CLASSIC SOLUTION: WELDING SAFER FOR CLASSIC STAINLESS COMPANY
Well-established and progressive NZ-owned Classic Stainless Steel Ltd, not only has a total commitment to provide top class stainless steel products that represent excellent value for money, it also places staff welfare top of the company’s agenda.
The Auckland-based business has a team of full time welders manufacturing a huge range of stainless steel items, individually tailored to client requirements, which include benchtops for both residential and commercial applications, as well as shower trays.
Classic Stainless Steel has 37 years manufacturing experience using stainless steel , started up by two business partners, and although the core of the business has been the manufacturing of traditional stainless products, over the intervening years there has been a shift to supermarket fitouts, hospital and hospitality projects says Andrew Grimmer who contacted NZDuct+Flex to solve their fume issues as the amount of welding gases and chemical smoke increased in the busy workshop.
Truly efficient fume extraction that effectively removes fumes, smells and associated dusts, must be operated as close to where these problems are generated as possible. Because of this, NZDuct+Flex fitted six 4-metre long fume arms to give maximum reach to accommodate the variety of work carried out, and the arms were supported in pairs by a stand, each with extraction from three 2.2kw fume fans on the roof.
The fume arms and fans are all from European supplier Oskar Air Products making the installation very simple, as all their components fit together, and the arms can be connected directly to the fan units, (via the brackets) if necessary.
A fume arm and hood connected to the right extraction, positioned correctly and constantly repositioned as the welder works, is the cheapest and best solution to deal with welding smoke and fumes. NZDuct+Flex has the largest range of fume arms in stock starting with the 75mm arms with a 1 metre reach up to the 160mm dia. and a 4-metre reach arms chosen here. The distinctive arms have blue powder coated metal tubes (also available in stainless) with external hinging to make minimal maintenance possible – no down time to clean and un-jam internally articulated arms.
From one of Europe’s leading suppliers, the fume arms and fans are incredibly good value, the arms can be wall mounted if the weld area is in bays or attached to a boom giving a phenomenal 8-metre reach if required. If a static situation is not well suited to a particular production line, the arms can be incorporated into a channel system and moved backwards and forwards to where needed: a perfect solution for assembly lines with a linear work flow.
“Our suppliers have been around for decades and their products have been tried and tested and enhanced over this time. No other company can offer what we offer in New Zealand, a source of LipLock modular ducting components, fans, and fume filtration units, guaranteed to work as a system efficiently and effectively, “ says NZDuct+Flex sales manager Geoff Ebdon.
Andrew says he was impressed with the install carried out by permanent staff from NZDuct+Flex, and was particularly grateful that they were happy to work around the production needs on the day, ensuring there was no down time for the busy workshop.

CELEBRATING 40 YEARS OF MANUFACTURING INNOVATION
Helping clients stay at the leading edge of their respective industries has always been a driving force behind everything Mulcahy does.
When Murray Mulcahy started business in 1980, his vision was to offer clients a total manufacturing solution.
It’s a vision that continues to be alive and well today.
“We don’t see ourselves as simply being a supplier of engineering services, but more as a manufacturing partner,” says Managing Director Kayne Mulcahy, who took over the running of the business from his father in 2012. “It’s all about enabling innovation for our clients.”
This partnership approach has taken Mulcahy from being a small facility with five employees in Gleneden, to having a 6000 square metre plant in Avondale and a team of 140.
Ongoing investment in technology is a key part of the company’s strategy. “It gives us complete control of our service deliverables, not only in terms of the quality of work produced, but also the timeframe within which the end result is delivered,” says Kayne.
When Mulcahy Engineering started operating in June 1980, the workshop only did manual processing.
It was a different world back then.
Plans and drawings were made on the coffee table. Pattern development was done manually on the floor of the workshop before being cut out with cutoff discs.
As the demands of the engineering and manufacturing world have increased over the years, Mulcahy has been at the forefront in providing the technology to meet those requirements.
Although always an early adopter of manufacturing technology, it wasn’t until 2000 that the company actually brought it inhouse. That was the year they purchased their first Trumpf L3030 laser cutting machine.
With a growth mindset and a focus on customer collaboration, this technology opened the doors to new industries which in turn paved the way for continued investment in additional plant.
Examples of this include a Trumpf TruLaser Tube 5000, which was purchased in 2018. This machine can bevel cut to +-45 degrees and process tubes of up to 8 metres in length.
Last year the business added two new Trumpf TruBend 5170s to their bending operation. The technology associated with the new machines allows the team to take a customer’s model and carry it across to the finished, folded part with complete accuracy, using innovation such as TechZone bend offline programming software.
Today, Mulcahy’s capabilities include laser cutting, punching, pressing and the full scope of fabrication services such as polishing, machining and welding.
The customer base encompasses the food and dairy industries, materials handling, original equipment manufacturing, agriculture, horticulture, and architectural.
A highly skilled team of designers and engineers ensures that even the most complex or large-scale projects can be turned around quickly, from the initial concept right through to the delivery of the finished item.
Kayne is confident about what the future holds. “We’re really focused on a strategic five year plan that’s going to put us in a great position to thrive for the next 40 years and beyond.”
Helping clients stay at the leading edge of their respective industries has always been a driving force behind everything Mulcahy does.

PRIME PUMP: THE PUMP VERSION OF HARE VS TORTOISE – SAME RESULT
Slow-running, high performance Wangen pumps offer outstanding, dedicated wastewater management solutions thanks to low life-cycle costs and some of the most advanced engineering in the world.
These pumps could provide some much-needed answers for the increasing number of under-pressure New Zealand cities whose ageing wastewater infrastructures are now reaching the end of their lives. Already deployed very successfully in one major city, Wangen delivers a much more cost-effective and enduring solution compared to the all-too-common, and ultimately very expensive, fall backs of short-term repairs or the relatively short-life options of competing pump brands.
Sourced from Germany by innovative New Zealand company Prime Pump, hard-wearing Wangen progressive cavity pumps are already very well-established in Europe. But far-sighted locals are also catching on. That’s according to Ben Petrie, Prime Pump key account manager. “Once clients have tried Wangen, they’ll never go back.”
His view is backed-up by users in other industries such as the agricultural effluent sector.
One key client says almost as soon as Prime Pump brought Wangen into New Zealand, he thought it was worth a look. And it’s more than rewarded his confidence. In two years, his company has seen some “fairly catastrophic” failings with other pumps of the same age, but none with German-engineered Wangen.
“The whole Wangen design is better,” he says highlighting the durable Cardan universal joint, in particular.
“They’re a really nice pump. And being slower running is a real advantage. It’s quiet, performs very well and it’s just logical that anything running slower will last longer.”
There is a very solid history behind Wangen’s success. Wangen Pumpen, which manufactures the pumps in the historic German city of the same name, located on the Bodensee, was founded in 1969. The region has a legacy of manufacturing that goes back to the Middle Ages and Wangen, as a company, has continued that venerable tradition. At the same time, it’s driven by a desire for continual improvement, extreme precision, resilience, and a dedication to ensuring long life in all its products.
Prime Pump are committed to travelling the world to find the best quality pumps, designed and manufactured to suit New Zealand conditions, and they back them up with guarantees and service. They say Wangen has more than met their expectations, not least because of its extreme hardiness. (There are well-documented examples of pumps running intervention-free for over three decades. One Wangen pump owned by an Austrian client, Mr Maier, has run for 35 years, without the need for repairs.)
The extended life of Wangen pumps comes from some significant design advantages over and above others in the market.
One of those keys to the Wangen pumps’ performance is the Cardan joint; a critical design feature. This universal joint-like system is superior to the conventional pin joint. The pin joint wears, often rapidly, resulting in characteristic “sloppiness” and ultimately the need for regular replacement. In contrast the Cardan joint operates smoothly and seamlessly, lasting the lifetime of the pump. The design, which has the same diameter as the rotor ahead also avoids constraint in the flow, and the problem of settling, which effectively removes the issues related to fibres becoming wrapped around the shaft.
A one-piece cartridge mechanical seal, filled with oil, rather than a traditional two- piece mechanical seal, is also far easier and quicker to fit while the oil, again, helps extend the life of the seal.
An extra bearing housing between the gear box and pump adds additional rigour to the structure and supports reliable performance.
The system also enables councils to customise to meet individual requirements thanks to the pumps’ ingenious modular construction and a wide range of standardised components. Available for all Wangen series pumps, this makes customising pumps to meet individual needs and environments, if not straight forward – entirely possible.

HI-TECH METALS GETS CUTTING EDGE TECHNOLOGY
Now one of New Zealand’s leading laser cutting companies with the introduction of the 12kw Bystronic fiber laser.
The Hi-Tech Metals warehouse is spacious and tidy. Racking is neatly stacked down the centre and an array of machines line the walls.
Filling one side of the room is something that looks at first to be out of place. A new colour scheme to a largely red and black layout. To the uneducated eye it appears a bit like a high-speed bullet train. It’s not though, it’s their latest piece of high-tech equipment – the 12 kilowatt ByStar 3015 Fiber Laser from Bystronic.
Edan and Michelle Newell have run Hi-Tech Metals for almost 15 years now and previously have only purchased machines under the Amada brand. However, with technology developing at rapid speeds, the high-powered piece of technology is the very best on the market.
Last year, the pair travelled to Switzerland and took a tour of the Bystronic factory. Impressed by what they saw, the philosophies of the company and the workmanship, they decided that to keep ahead of the game they would need to buy something new to the market that no-one else had.
With this, they became the proud owners of the first ever 12kw Bystronic laser machine in New Zealand.
“We have a massive loyalty and a great history with our previous supplier but the laser cutting technology is evolving so quickly. Top manufacturers are getting out of phase as they leapfrog each other and timing is now so important when purchasing new equipment,” says Edan.
“Even just a few years ago, technology was developing at a much slower pace. A machine would last a good few years in a company before needing to be upgraded.
“Power is taking leaps and bounds,” he says. “For the first five or six-years of fiber laser technology, a range of companies only produced 4-5 kw fiber lasers and they stayed like that for so long. Then all of a sudden they’ve jumped up to 6kw, 8kw, 10kw, 12kw and even 16 and 20 with talk of 30kw machines. The development side of the industry is just intensifying so much.”
“Some suppliers will rush machines into production and others will take their time. Because of the short time frames and the leaps in technology, they are getting out of sync with each other. What is impressive this month is surpassed by another next month.”
For this reason, Edan and Michelle wanted to get the latest and most powerful laser cutter available so that Hi-Tech could provide faster cutting speeds and offer superior cut quality in the thicker market.
Auckland has an array of laser cutting companies now and last year there was a noticeable number of impressive machines arriving into Auckland. Companies were investing in the new 8-10 kw laser cutters and Edan and Michelle knew that following what others had done just wouldn’t ‘cut’ it.
“There was no point getting another 8-10 kw laser cutter and competing on that level. For us, ever since we started, we have always been fortunate enough to purchase the latest technology.”
It was a big step for the company to branch out to another brand and Edan says the transition has had a steep learning curve.
“Brand loyalty had to step aside for timing and the desire to stay on top at that point in time, rather than waiting for the next best thing. There are some great sheetmetal companies in Auckland and some really smart people. They are all putting in good machines which means that there is an influx of laser cutters coming into Auckland. This new 12kw machine is all about power. It’s harder to compete against 8 and 10kw machines with a 5 or a 6kw. You need to be right up there and buying the exact same machine that other people have doesn’t give you that necessary edge in what is a tight market.”
As well as being significantly more powerful, the new machine is also a new series with a brand-new cutting head which Edan expects to increase production by 20% over the older models.
It has also allowed them to take on new clients and new jobs that they previously couldn’t do.
“That’s another key part of why we bought this machine. We were traditionally a sheet metal company specialising in 5mm and below. While we could process thicker material up to 16mm we were never that efficient at it. We didn’t buy our old machines to get into the plate business. We never wanted to cut 25mm but now you can buy a machine that’s fast, has made a big improvement in the thinner market but also has huge capabilities in the thicker market too.
“Now we can do jobs we’ve never been able to look at before which gives us the opportunity to service both ends of the market – customers who require thicker parts cut accurately.”
The machine also allows for ‘lights out’ manufacturing. This automation of the Bystronic ByTrans Extended gives the machine another competitive edge over other companies as the ByTrans can take a pallet of material and process it without needing an operator to be there.
This in turn reduces overhead costs and increases overall processing times which mean Hi-Tech Metals can offer faster turn arounds and more competitive prices.
The advantages of this new 12kw machine will only open up more opportunities for this company that already operates smart. Offering quality laser cut components now up to 25mm, coupled with the most accurate of folded components will keep Hi-Tech Metals ahead of the game.
“We’ve never been one to follow what other people have done. We have always aspired to be different to all the others.” And the new ByStar 12kw does just that.
PACKAGING MACHINERY MANUFACTURING GROWS AGAIN
Last year, 2019, was the ninth consecutive year of growth for packaging machinery manufacturers from Germany.
According to the Federal Statistical Office, the approximately 250 mainly medium-sized companies produced packaging machinery worth around 7.3 billion euros, an increase of 2 percent. The production of beverage packaging machines increased by 4.3 percent to 2.3 billion euros. The production of other packaging machines increased by 1.2 percent to just over 4.9 billion euros.
While the production figures for packaging machinery in the first three quarters of 2019 still showed a total increase of 8 percent, they fell in the fourth quarter by 10 percent below the previous year’s figure. The slowdown in demand in the second half of the year was already affecting the German production.
Europe remains largest sales region
Half of all German packaging machinery exports went to European countries. The delivery volume reached a value of 3 billion euros and was thus 3.1 percent above the previous year. Asia purchased machinery and equipment worth just over 1.1 billion euros (plus 16 percent) and North America worth 886 million euros (plus 8 percent). Deliveries to Africa amounted to 351 million euros (plus 1 percent). Less positive was the development of the export business to Latin America, the Near and Middle East and Australia-Oceania. Exports fell by a double-digit percentage.
USA largest single sales market
With an export volume of 786 million euros (plus 7 percent), the USA remained the largest single sales market for packaging machines made in Germany in 2019. China is in second place with 451 million euros (plus 23 percent), followed by France (309 million euros, plus 3 percent), Poland (296 million euros, plus 9.5 percent) and the United Kingdom (248 million euros, plus 18 percent). Exports to Russia increased by 5 per cent to 203 million euros. This puts the country in eighth place among the ten largest export markets, after Spain (234 million euros, up 24.5 percent) and the Netherlands (219 million euros, up 29.1 percent).
Outlook: Everything open
It is currently impossible to estimate or quantify how the packaging machinery industry will develop in 2020. Due to the weak order activity in the second half of 2019 and, in particular, the drop in foreign orders, the German Food Processing and Packaging Machinery Association already assumed in its November 2019 forecast that production of packaging machinery would decline in the current year.
“The extent of the decline caused by the outbreak of the corona crisis and the consequences associated with it will only become really clear in the coming months,” says Richard Clemens, managing director of the VDMA Food Processing and Packaging Machinery Association.
Companies are increasingly feeling the effects of the corona pandemic. In addition to disruptions in the supply chain, especially in Europe, disruptions on the demand side in particular have increased further. Not only are fewer orders coming from Europe, but also from Asia and North and Latin America. Order intake in the first quarter was down 19 percentage points year-on-year. If this trend continues, it will continue into the coming year.
“However, we are optimistic that demand will recover quickly following the easing of government restrictions. The increasing global demand for hygienically packaged and safe food and pharmaceutical products is a major contributor to this,” says Clemens.
END OF AN ERA FOR MAJOR MACHINERY COMPANIES
After more than 40 years in business, Aotea Machinery announced that on May 15 the company has gone into liquidation along with PT Equipment Limited.
“On 15 May 2020 at 8.40 am, it was resolved by special resolution of shareholders pursuant to section 241(2)(a) of the Companies Act 1993 that Aotea Machinery Limited and PT Equipment Limited be liquidated and that Christopher Carey McCullagh and Stephen Mark Lawrence of PKF Corporate Recovery and Insolvency (Auckland) Limited, both RITANZ Insolvency Practitioners accredited by CA ANZ, be appointed jointly and severally as liquidators for that purpose,” a public notice stated.
Aotea has been a leading provider to New Zealand’s manufacturing industry, with a range of equipment for sheet metal, CNC, fabrication, injection moulding and more.
PT Equipment Ltd traded under the name Sheet Metal Tooling and was the New Zealand agent for German brands Pass|Stanztechnik and UKB, and Yestool from Korea.
The liquidators have fixed July 15, 2020 as the day on or before the company are to make their claims and establish any priority their claims may have.
BUDGET TO BOOST CIVIL ENGINEERING AND CONSTRUCTION SECTOR
More than $1.2 billion has been set aside for rail infrastructure in the Budget 2020 and could significantly boost to New Zealand’s civil engineering and construction sector says State Owned Enterprises Minister Winston Peters.
This includes $246 million to support investment in the track and supporting infrastructure, $400 million to help replace the Interislander ferries and associated portside infrastructure and $421 million for new wagons and locomotives.
Changes proposed through the Land Transport (Rail) Legislation Bill will also provide long-term certainty for rail by allowing network investment to be channelled through the National Land Transport Fund. Budget 2020 provides $148 million to support the fund to make these investments once the Bill has been passed.
Mr Peters says this is a milestone in securing the future of New Zealand’s rail system, and a step towards economic recovery.
“Rail is a critical part of our integrated transport network. Not only is investment essential to address decades of under-investment, but further investment in rail will play an essential role in our economic recovery post-lockdown,” Mr Peters says.
“KiwiRail is a major contributor to New Zealand’s infrastructure projects, and currently employs almost 4,000 people.
“The investment in rail infrastructure, is not only helping to secure the thousands of existing jobs at KiwiRail but will be a huge boost to New Zealand’s civil engineering and construction sector, with hundreds of contractors, and their material suppliers, needed nationwide for track renewal, mechanical facility upgrades and ferry terminal projects.”
Transport Minister Phil Twyford says these investments will help future proof the economy and reduce emissions.
“The Coalition Government has a bold vision for a 21st century rail network as outlined in the draft New Zealand Rail Plan. We need a resilient and reliable rail system to support freight and get our cities moving.”

PRESTIGIOUS AWARD RECOGNISES ENGINEERING IMPACT
Dr Yifan Chen
Internationally recognised academic leader and University of Waikato Professor Dr Yifan Chen is the recipient of the prestigious Engineering New Zealand Fellows Award.
Dr Chen has worked in many well-renowned international universities and pioneered the emerging field of computational nanobiosensing, which involves smart tumour targeting using nanorobots.
These nanorobots can search for tumours by learning the biological environment. He has also contributed to the technological, clinical and commercialisation advancement in the area of microwave medical imaging and sensing.
The Engineering New Zealand Fellows Award recognises those who have made an impact on engineering in New Zealand and inspired others in their industry.
Professor Chen says receiving the award and being recognised by a leading engineering body in New Zealand was a great honour.
“Since joining the University of Waikato in 2017, in my role as Associate Dean External Engagement for the Health, Engineering, Computing and Science Division, I have fostered external linkages with top universities and institutes, particularly in China,” he says.
Dr Chen developed a wide range of electromagnetic medical examination technologies for low-cost healthcare, including microwave breast imaging, microwave stroke detection, and microwave cognitive impairment detection in collaboration with medical instrument companies and universities in the UK and China.
Professor Chen has also been elected as a Fellow of the Institute of Engineering and Technology (FIET) due to his innovation in the area of wireless technologies in medical diagnostics, therapy and information transmission. He is also currently part of several research projects, including one looking at developing hand-held high-resolution medical imaging in conjunction with Lincoln Agritech, the University of Auckland and the Université Nice Sophia Antipolis.
“As well as that project, I’m also looking into a portable low-cost microwave brain scanner for stroke detection and recovery monitoring, and I am writing a book on ‘Computational Nanobiosensing’ for Cambridge University Press, which would be the first book on this emerging area in the market,” says Professor Chen.
The award ceremony and dinner was to be held at the end of March however it was postponed due to COVID-19 and will now be held later in the year.
3D PRINTING PROJECT COULD BE USED TO STUDY COVID-19
UC Mechanical Engineering Senior Lecturer Dr Yilei Zhang
New technology being developed by a University of Canterbury mechanical engineer could be used to study the effects of Covid-19 and screen potential cures.
Senior mechanical engineering lecturer Dr Yilei Zhang is working on a prototype of a 3D printer that uses hybrid laser beams to speed up production and retaining accuracy.
He says the technology could be used to quickly print in-vitro organ models to study the virus’ effects, or to screen drugs that might potentially cure it.
“We’ve developed a novel hybrid, high-speed 3D printer based on laser beam shaping technology, which allows us to print large, complex structures faster than traditional 3D printers. This technology has broad applications in high-speed 3D printing of engineering and biological products.
“In the biomedical field it could be used to make not only scaffolds for tissue engineering, but also in-vitro organs with cells embedded inside for implantation.”
The technology would also allow for mass production of highly complex and accurate items, Dr Zhang says.
“3D printing is normally quite slow because it involves adding a thin layer of materials at each step, which enhances accuracy but reduces productivity. By using hybrid laser beams we can print fast without compromising on quality.”
Additive manufacturing is recognised as one of the key elements of future manufacturing and is already used in the aerospace, food, agriculture and marine industries.
Dr Zhang expects to have a working prototype for the printer ready in six months and has sponsorship from Auckland-based technology incubator Astrolab.
His project is also a UC Innovation Jumpstart 2019 winner, which means he receives $20,000 to help with experimentation and development.
