W. Amsler to Supply Npe2018’s Bottle Zone Beer Garden with Pet Beer Containers

Heidi Amsler

W. Amsler Equipment, the supplier of all-electric linear PET stretch blow moulders will use its single-cavity PET stretch blow moulder to produce bottles for NPE2018’s bottle zone beer garden.

The company will supply Craft beer in barrier PET bottles to be sold throughout the week at

in the Beer Garden, which is part of NPE’s Bottle Zone, an area consisting of 40 exhibitors who work in PET packaging.

The company worked with numerous suppliers and vendors including Bill Droste, a partner with Orlando Brewing in Orlando who had a pre-existing arrangement to supply beer in glass containers with the Orange County Convention Centre.

The 12oz, 36-gram preform was designed by Amsler with assistance from Athena Automation and Yudo Valuepro.

Amsler had to maintain the bottle height for filling but shortened the shoulder to compensate for the wall thickness in a glass bottle.

The preform was designed to accept a standard metal crown closure and optimised for the required axial and diametrical stretch ratios as well as core and cavity draft for preform moulding.

Amsler selected a monolayer structure with barrier additive for the barrier material which would allow the moulding of PET preforms on any injection moulding machine equipped for PET.

The company says it has also created barrier clear bottles to target the growing cider market.

Heidi Amsler, Marketing Manager for Amsler, said: “It was a stiff challenge but we were up to the task so that the Bottle Zone had another interesting feature to draw attendees.”

W. Amsler will be at NPE2018 7th-11th May at Booth #S21067.

The quest to produce quality bottles with greater precision and speed is being met with investment and innovation by blow molding machine manufacturers.

New products and next-generation models on exhibit at NPE2018 will show advances in repeatability and flexibility for primary equipment buyers in the automotive, beverage, cosmetic, health care and other markets.

For custom blow molders, W. Amsler Equipment Inc. has amped up the second version of its four-cavity stretch blow molding machine and will display it at Booth S21067. The L42X has gone from 3 to 12 Bosch-Rexroth servo motors and now has four parallel heating ovens — one for each cavity — to allow for more precise adjustments compared to a single continuous oven.

“We’ve been talking about this machine for a couple years. Nothing else like this is manufactured in North America,” Amsler Sales and Marketing Manager Heidi Amsler said in a phone interview.

She pointed to the new oven system, saying, “There’s a lot more control over the process. When you’re running four bottles, you don’t want a variance from the first cavity to the second or last.”

The extra servos improve repeatability and reduce energy use yet have fewer cables, according to the company. But Amsler expects another feature to impress businesses that run smaller loads with fast changeovers, maybe making trigger spray bottles one day and bear-shaped honey bottles the next. She said the L42X shines in operations that run a wide variety of containers.

“The range of bottles that can be made sets us apart,” Amsler said. “We can run bottles from 50 milliliters up to 5 liters with neck sizes from 18 mm to 70 mm.”

In addition, the machine is equipped with a larger touchscreen control for the operator and a Windows-based human machine interface with access to assembly drawings, bills of materials, set-up guides, trouble-shooting tips and training videos.

Founded in 1994, Amsler, a privately held Richmond Hill, Ontario-based company, is the only North American manufacturer of all-electric linear PET stretch blow molders. General Manager Bruce Coxhead will give a presentation on linear blow molding of non-conventional barrier containers at 10:45 a.m. May 9 at NPE’s Bottle Zone.

Bekum America Corp. (Booth W2127) says it will introduce the U.S.-made 407DL machine in response to the growing need for a high-speed bottle maker. The machine offers the benefits of a double-shuttle long stroke machine platen as well as cost-efficient production of smaller bottles, especially for personal care products, according to the company.

Molds can be changed in 15 minutes without the use of tools, Bekum says, and the machine provides “a very attractive” cost-output ratio. Bekum will demonstrate features of the electric version by producing 1-liter round, 3-layer personal care bottles made from HDPE.

The 407DL machines also come in hydraulic and hybrid versions and include Bekum’s patented C-Frame clamp design.

 

W. Amsler Equipment Inc. will display its four-cavity stretch blow molding machine with a larger touch screen control.

Kautex Machines Inc. (Booth W1543) will show how it expanded the range of its small-size KBB all-electric machines. The company added capacity for the machine line as well as its KSB suction blow molding machines to meet growing demand.

In December, Kautex opened a new assembly hall at its manufacturing facility in Bonn, Germany, where it increased capacity for more than 60 machines a year.

Kautex also will demonstrate a virtual training machine for its KCC range of hydraulically driven machines at NPE.

Pet All Manufacturing Inc. (Booth W6545) will put three new all-electric technologies on display. The Markham, Ontario-based company will exhibit a blow molding machine (IBM 300/700) suited for clean rooms, an injection stretch blow molding machine (ISBM-180E), and a PET stretch blow molding machine (CPSB-1000 LLE) for 15 liter containers.

Show manager Zoe Webster says the machines provide energy savings and have faster cycle times than their hydraulic counterparts.

Barcelona, Spain-based Side SA (Booth S16084), which manufactures PET blow molding machines, will focus on an engineering solution for containers that need a handle molded from a preform.

“The T-handle system is the simplest system that can be found for producing containers with handles,” Side Sales Director Josep Jimenez said.

Graham Engineering Corp. (Booth 2743), which is based in York, Pa., has expanded its proprietary control system called Navigator to all company’s brands, which includes Welex and American Kuhne from earlier acquisitions.

The control technology uses an industrial PC with a Windows platform to improve extrusion process control. Navigator’s hardware is designed to withstand environments considered harsh because of vibrations, temperature and humidity.

“The ease and ability to integrate is boundless,” Justin Kilgore, Graham’s vice president of engineering, said in a news release, noting synchronized supervisory control of a line is possible as well connectivity for data collection systems and remote support and trouble-shooting.

“Navigator offers integration without limits,” Kilgore added.

Graham also will have six processing systems on display, including its Mini Hercules accumulator head blow molder, a modular clamp station for its Revolution MVP rotary wheel blow molder; the Welex Evolution sheet extrusion system; American Kuhne’s Ultra extruders with expanded features; American Kuhne’s tri-layer medical tubing line; and American Kuhne’s AKcent co-extruder.

New-generation electric drives allow stretch blowmolding equipment manufacturer to reduce machine design complexity and improve its motion control capabilities

Caption: (From left) W. Amsler Equipment sales and marketing manager Heidi Amsler, company founder Werner Amsler, director of operations Jason Amsler, and Bosch Rexroth Canada’s technical consultant Paul Thiele pose for a team photo in the reception area of the company’s Richmond Hill, Ont. plant, which manufactures high-quality stretch blowmolding machines for customers across North America.

Building heavy-duty machines to produce mass quantities of everyday packaging necessities like plastic bottles around the clock is a job best-suited for a rather elite group of companies in the global packaging machinery business. And it’s a group where Canadian technical and engineering skills are widely renowned and celebrated far more than the average Canadians know—thanks to W. Amsler Equipment Inc. of Richmond Hill, Ont.

Founded in 1994 by Werner Amsler, the family-owned company has consistently displayed a remarkable knack for making high-quality stretch blowmolding equipment over the years, which has earned it a very special place and plenty of respect in the market traditionally dominated by large overseas manufacturers of far greater size.

To compete in this highly competitive marketplace, Amsler’s Richmond Hill operation boasts a wealth of technological prowess and expertise driving the daily design and manufacturing excellence packed into every high-speed blowmolder and other related machines assembled there.

“We take pride in our unique status of being the only North American manufacturer of all-electric linear PET (polyethylene terephthalate) stretch blowmolding equipment,” sales and marketing manager Heidi Amsler told Canadian Packaging on a recent visit to the company’s lively 20,000-square-foot facility just north of Toronto.

In addition to blowmolders, the Richmond Hill plant also manufactures empty bottle leak testers, spin trimmers and various downstream filling equipment for leading custom bottle blowmolders like Berry PlasticsAmcor and other key suppliers of PET plastic containers to the global beverage, cooking oils, agrochemical, health-and-hygiene, and other industries always in need of a steady supply of strong, well-made plastic containers to ship and market their products.

“The machines are designed and built right here in Canada with the primary idea of providing our customers as much machine uptime, and requiring as little maintenance, as possible,” Amsler explains.

Amsler-2-540x450

VALID POINT

“The whole point is to enable our customers to run as many bottles as they can to increase their revenue and improve their bottom line,” she says, “rather than spending their time on maintenance and changeovers.”

As Amsler explains, the company manufactures three types of PET stretch blowmolders to accommodate the production of almost all the popular types of plastic bottle shapes and sizes, including:

  • Small-neck bottles with 20-mm to 63-mm neck finishes, used for miniature single-shot liquor bottles to peanut jars, in volume capacities ranging from 20-ml up to five liters;
  • Wide-mouth jars, with neck finishes from 70- mm to 120-mm, to produce two- to five-liter PET bottles;
  • Bulk jars ranging from five liter water jugs up to 22-liter containers used as beer kegs and bulk food containers widely used in the foodservice and hospitality industries, as well as for packaging all sorts of household care and industrial cleaning products.

“Depending on the model, our machines can achieve output rates ranging from 1,500 to 1,800 bottles per hour per cavity,” Amsler states, noting the company offers its machine in one-, two, three- and, more recently, four-cavity versions to suit the end-users’ varying production needs.

“Many bottle manufacturing sites run our machines flat-out run on 24/7 schedule.”

“Customers are always looking for maximum reliability and output: in other words machines that will deliver the most uptime and reliable, highly repeatable production,” says Amsler, “which is why we are using a lot of Rexroth servomotors and servo drives in our machine design to optimize the stretch blowmolding process.”

Amsler-3-552x450

Amsler machinery uses the so-called two-step stretch blowmolding process, whereby its machines are fed pre-made, test-tube-shape PET preforms that are transferred inside the machines’ ovens—heated via high-intensity infrared lamps—and placed into molds.

A metal stretch rod then pushes the plastic, forcing it to stretch to the length of the mold cavity, which then balloons out by compressed air and internal pressure, stretched in hoop and axial directions, and adheres with the shape of the mold walls.

After it cures and cools down, the newly-formed bottle is ejected from the mold, with the whole process taking mere seconds to finish.

The stretch blowmolding process allows for the use of many complex designs to produce a broad variety of attractive, fully-recyclable cylindrical, rectangular or oval PET containers, with the round two-liter beverage bottles being one of the most commonplace end products made using this process.

Amsler-4-630x260

TIMELY RESPONSE

Like all machine manufacturers, Amsler Equipment is continuously upgrading its machinery offering to respond to evolving market demands and customer expectations in timely manner—working with many technology partners to improve its product offering.

Over the last 20 years, Amsler has built a tight partnership with Burlington, Ont.-based industrial automation specialists Bosch Rexroth Canada Corp. by incorporating many Rexroth servomotors, drives and other electrical system components into its equipment to ensure optimal motion control for all the many different moving parts inside the machinery used to turn preforms into finished bottles.

“Over the last 20 years or so, Rexroth has been a very good partner for us in terms of providing outstanding service, technical support and engineering assistance,” Amsler relates, describing Rexroth’s significant role in helping Amsler develop its next-generations L42X four-cavity linear stretch blowmolding machine, launched earlier this year.

“We have recently redesigned our four-cavity L42 machine into a next-generation system that has many more servos, more speed and a lot more control over the whole process,” she says.

Like its L42 model predecessor, the L42X can blow bottles up to two liters in size using four cavities, Amsler explains, and bottles up to five liters in two cavities, but whereas L42could only achieve maximum diameter of 48-mm, the L42X can handle larger diameters of up to 63-mm.

Amsler-5-457x450

Featuring upgraded 1,000 W heating lamps and oven controls, along with a double-acting clamp to move both mold halves away from the centerline upon opening, the L42Xmachine makes optimal use of Rexroth’s all-new IndraDrive Mi drives—combining a drive and a motor in a single compact package— to implement game-changing transformation in the machine design, simplicity and performance.

Paul Thiele, technical consultant with Bosch Rexroth Canada Corp. in Burlington, Ont., has worked closely with Amsler for nearly 18 years, helping in the development of the original L22 model blowmolder and all the subsequent machine updates and reiterations.

As Thiele explains, incorporating the Rexroth IndraDrive Mi servo drives into the L42Xmodel blowmolder enabled Amsler to eliminate the need for an external control cabinet that would have been remotely wired to the machine—enabling for a much smaller control cabinet to be placed inside the machine itself.

Amsler-6-768x581

Amsler agrees: “One of the big advantages of being able to reduce the cabinet size is that instead of having a separate cabinet outside of the machine, we have it placed inside, while also vastly reducing the amount of wiring we had before.

“This allows end-users a much faster startup in the field,” she says, “and it makes machine positioning much simpler because they don’t have to worry about where they should place the stand-alone cabinet.”

Says Amsler: “The new servo systems has made the machine faster, reduced its maintenance requirements, and freed up extra space inside to enable us to include new value-added features such as preferential heating and automatic neck orientation, which is something that our customers have been asking for.”

Adds Thiele: “One of the Mi motor’s most important advantages is that it is actually a drive and motor package whereby the drive is mounted on the motor,, which dramatically reduces the required cabinet space.

“Because Amsler’s machines are designed for a compact footprint, in the past there was not enough cabinet space inside the machine to put all nine servos in. “Now there’s just one power source in the cabinet that power all nine motors/drives, instead of one for each axis.

“So one of the key advantages is the significant reduction in the costs of installing wires, wire trays and the wire cabinetry,” says Thiele,.

Amsler-7-575x450

Moreover, the new blowmolding machine is controlled by a Rexroth MLC (motion logic and control) controller that provides all the software architecture to control all the motion, logic and power distributed to the proper I/O (input/output) connectors.

“These benefits provide operators with the ability to make any necessary changes from one single source, so when they set up a new bottle for different sizes, they can download very quickly all the parameters to the drives and off they run with the new different set-up.

“It’s all very fast and very efficient,” he states, “thanks to the Rexroth MLC’s ability to have coordinated motion.

“This dramatically decreases the cycle time by overlapping motions to make the most efficient use of time and motion,” he states.

According to Heidi Amsler, the Rexroth IndraDrive Mi drives enabled Amsler to replace all the pneumatic systems and components used on previous machine models to control preform loading, unloading and rotating inside the ovens with the more precise and repeatable Rexroth servo control.

All in all, these enhancements add up to about a 10-percent improvement in the new machines overall performance, according to Amsler.

Adds Thiele: “Using the Rexroth Mi family of drives allowed Amsler to reduce the cabinet space by 85 per cent—making shipping and field startup much simpler and quicker—while also reducing the amount of field wiring by 85 per cent.

“Instead of having two wires going into each of the machine’s axes as before, there is now just one single cable that daisy-chains across all the different axes,” he says, “which in turns saves a lot of machine assembly time and all the related costs.

“Basically, the cable inside the machine goes inside one Mi motor, exits and goes on to the next axis, and repeats the sequence through all the nine drives, rather than having 18 cables running throughout the machine to control the drives.

“This also eliminates the need to install additional components such as starters and contactors,” he adds, “further freeing up more space to accommodate other new machine functions or features.”

In addition to the Mi drives, Bosch Rexroth also supplied the linear modules used to guide the finished bottle out of the blowmolder onto the exit conveyor, Thiele notes, as well as a Rexroth VFD (variable-frequency drive) with Sensorless Vector Control to power the exit conveyor.

Amsler-8-267x450

THE NEXT LEVEL

Above all, Thiele points out that incorporating the Rexroth IndraDrive Mi technology into the new blowmolder makes the L42X machine perfectly compatible with the emerging new Industry 4.0 working environment based on the constant exchange and analysis of machine data between all the different pieces of automated equipment employed at modern manufacturing plants.

“The Amsler L42X is ready for the Industry 4.0 workplace, where data collection from the machine will not only be possible, but will also be an important part of the bigger plant picture,” Thiele explains.

“Also, when Amsler is remote-accessing the machine for troubleshooting, they have the ability to look into each of the drives and their motion profiles to see if there is a problem on any specific axis.

“This is made possible because of the Rexroth MLC control software that provides the full view of the whole system,” Thiele adds.

“With the ability to see and analyze each axis,” Thiele continues, “Amsler can compare that data to previous data and recorded cycle times and see if there are any changes that may have been caused by a mechanical problem or a motor issue, to use as an example.

“The more you can see, the better you can service and support the machine.”

Amsler-9-625x450

Says Thiele: “This enables Amsler to do very detailed analysis on these machines and to make whatever tweaks are necessary to reduce cycle-times.

“It may only be a small tweak amounting to 10 milliseconds, but if you can reduce the heating time or blowing time from a three-second cycle to 2.99 seconds, it all adds up when you’re talking about multiple cavities, several machines, and continuous 24-hour operation.

“Industry 4.0 is all about information, quality control and process improvement,” he states, “whereby machines all talk to each other back and forth to generate more detailed information that can be analyzed and used to improve the overall performance levels.”

Adds Amsler: “When we were looking to develop this new machine we contemplated the idea of perhaps using other automation suppliers, but given our long and successful history with Bosch Rexroth Canada we decided that they were the best option for us.

“The outstanding work they have done with our new L42X machine fully validates our decision,” Amsler states.
“Working with Amsler for the last 20 years has been a great experience for Bosch Rexroth,” Thiele concurs.
“It is a company that’s demanding on itself as it is on its suppliers—always raising the bar for service and technical excellence.

“It’s often a lot of work,” he sums up, “but it’s always worthwhile.

“And as Bosch Rexroth continues to bring advanced next-generation technologies to the table, and as Amsler continues to expand its markets, we are looking forward to maintaining our mutually beneficial long-time relationship well into the future.”

We’re on Canadian Plastics – Unbottled

Heidi Amsler

Blow molding can make shooting hoops against LeBron James look easy. Blow molding consultants like to describe it as the most technically challenging of the molding processes, and they’re probably not wrong. Why? Because in the blow molding world, having a perfect mold isn’t enough — that mold can still make an unaccept-able part if the molder isn’t in total control of the entire process, including the many indirectly controlled vari-ables. Simply put, the blow molding process itself exerts a major influence on the end product.

Which is why it’s crucial for the machinery makers to keep improving their equipment and technologies. With that in mind, here’s a look at some of the latest developments in extrusion blow molding, injection blow molding, stretch blow molding, and automation.

RADICAL REDESIGNS

Amsler Equipment Inc. has rede-signed its four-cavity, linear stretch blow molding machine for PET. Like its predecessor, the L42, Amsler’s new L42X can blow bottles up to two liters in size using four cavities, and bottles up to five liters in two cavities; but in the new machine, the maximum neck diameter is 63 mm, compared to 48 mm in the prior version. Improved features include upgraded drives, heating lamps, oven controls, and control software and hardware. Additionally, all machine motions now are servo-controlled, giving the operator a better handle on all motions within the machine, including rotation of preforms through the oven. The L42X individually controls the heating of the four preforms before they’re moved into the molding area. The clamp is double-acting, so that both mold halves move away from the centreline upon opening; clamp compensation acts on both sides of the mold.

L42X Amsler Equipment has redesigned its four-cavity, linear stretch blow molding machine for PET. Like its predecessor, the L42, the L42X can blow bottles up to 2 liters in size using four cavities and bottles up to 5 liters in two cavities. In the new machine, the maximum neck diameter is 63mm, compared to 48mm in the prior version.

What’s new? The machine, which Amsler launched last month, and its numerous improved features, including upgraded drives, heating lamps, oven controls and control software and hardware. All machine motions now are servo-driven. The L42X individually controls the heating of the four preforms before they are moved into the molding area. The clamp is double-acting, so that both mold halves move away from the centerline upon opening; clamp compensation acts on both sides of the mold. The far right photo shows heated oven banks without preforms. The inset photo shows preforms entering an oven bank.

Benefits Performance, ease of use and robust construction. Due to the use of servo motors, the operator has better control of all motions within the machine, including rotation of preforms through the oven. The new machine improves output by more than 10 percent.

Customer : Impact Plastics, Ontario, Canada
Machine : MAG two-cavity SSB20-HP
Machine Manufacture Date : 1999
Preform Slide Upgrade Install Date : November 2015

Impact Plastics was experiencing issues with their preform loader. No engraved scales were available to record settings for repeated setups. The original aluminum parts were worn and the slide was hard to adjust.

Before the upgrade, only one side of the preform slide could be adjusted at the top when adjusting the unscramble rollers and only one side of the preform slide would move, making slide alignment difficult. As a result, the preforms could drop out of or get stuck in the slide, causing a preform jam. This would also make changeovers more time consuming, due to trial and error.

With the new system, the operator uses the roller in the top section to make the initial adjustments as usual and then he can adjust each side of the rails individually if needed. A heavy-duty adjustment mechanism with bushings has been installed at the lower end of the rails. This lower adjustment uses a hand knob, lock nut, left and right-hand threaded rod which allows for easy even adjustments on the two sides of the preform slide. Scales were added in all sections to provide repeat ability.

The new rails replace the existing upper preform rails.
Installation time is approx. 4 hours.
