Moldmaking is a challenge that starts with our customers’ product concepts and designs, and every mold we design and build is the heart of our customers’ production system. We are always thankful to get recognition from our valued customers and industry peers.
During the 19 years that Goplas has been operating, we have bought molds from many companies in different countries; Italy, Germany, Mexico, China and Canada. From all of the injection molds that we have, only two have delivered results that are above the expectations that we had for them. Both molds were made by StackTeck in Canada.
“Our molding technicians said, of the 3 new molds we received, we liked the StackTeck tool the best. It’s a first class 2x2 5 Liter Container stack mold.”
Stackteck provides a great product made by knowledgeable, experienced and caring people. The process of buying tooling is moved along rapidly from quotation to start of production. The online review of the tooling before manufacturing is always excellent.
StackTeck’s TRIM proposal dramatically light weighted a thinwall container resulting in a weight reduction of more than 35% - a key accomplishment in our overall sustainability strategy. The costs to change the part were minimized by a plan to replace core components only in the existing production mold. Once converted, the mold continued to run with the original molding machine and IML automation. 90% of the surface area of the container was thinned out to unprecedented levels while maintaining top load strength, high quality IML decoration, original rim thickness and bale lug features for the pail handle.

I contacted StackTeck as a result of the recommendation from other companies that had worked in other projects with them. Based on that recommendation, we did an evaluation of StackTeck to determine if their capacity and vocation were suitable to fulfill the expectations that INOVA PHARMAPLASTICS S.A. de C.V. had.
In the evaluation of the company, we visited their facilities and interacted with their specialists including the ones that manufacture the molds as well as their representatives in Mexico, whom surprised us greatly and surpassed the technical and service expectations that can be anticipated for a specialty supplier.
They always showed their professionalism and seriousness during the development of the project, and they inspired trust in our working team in each of the stages of the project and all the way to its successful completion.
The fact that they have first class manufacturing facilities and a center to test molds with similar characteristics to those of a production plant that can be used to fine tune molds before they are shipped to the customer, allowed for the project to be done in a safe and transparent way for us.
It’s because of all of the above that I highly recommend StackTeck as a supplier of molds and post-sale mold service as they are a company that is serious, responsible, organized, and passionate about customer service and the execution of successful projects.
I recommend StackTeck because they are a serious Company with great technology and an outstanding team that provides quality and effective solutions. The mold quality is excellent and the mounted molds work according to their specifications, complying with their availability and efficiency.
Working with a company like StackTeck generates trust right from the start since all of their team members are highly qualified to provide solutions according to the proposal needs in an organized way, showcasing benefits and restrictions right from the project launch. The follow up and accuracy in how the projects are executed instills security and trust, aside from the post-sale and installation services which turns them into our partners.
“StackTeck truly delivered for us in the incredibly short timeframe we required to make the injection molds needed to produce face shields for healthcare and other frontline workers,” said Ken Meyers, Vice President of Operations for WNA, a Novolex company. “We’ve worked with and depended on StackTeck technology for many years and our trust in their know-how was renewed yet again on this emergency project.”
GL Plásticos y Empaques is very grateful and satisfied with the cutlery family molds made by StackTeck, as well as the support provided for the development of an improved product for the food industry. The design of this cutlery is pioneering in the Mexican market. It is 100% certain that we will continue our growth hand-in-hand with StackTeck since they were a fundamental part throughout the development process of our product.

"We are very pleased with the new system, which provides competitive cycle times while dramatically reducing the overall part weight and light blocking additives of a monolayer bottle by means of a multi-shot process. This results in a dramatic reduction in part cost, while delivering improved light barrier properties. We chose to work with StackTeck and Niigon, as innovative suppliers who bring state-of-the-art capabilities to high volume molding systems," said Russell Gray, COO of Ngoc Nghia Industry.
"The StackTeck mold includes an advanced Yudo hot runner, which helps improve our part quality with superior hot runner balance. At the same time, the hot runner pressure drop is much lower than conventional hot runners, which enables the molding of the thin layers needed for this multi-layer part design." Mr. Gray continued, "It's an exciting technology to work with, we've expanded our testing to include parts with pearlescent colours in the inner layer and clear PET in the outer layer; the final parts have a glossy, "candy-apple" look that gives great shelf appeal and significant savings over a monolayer bottle with 100% blended pearlescent colours. We see opportunities for cosmetics and personal care packaging beyond the original focus on beverage packaging.”
According to Envases CMF Operations Manager, Luis H. Girod: “StackTeck has not only been a supplier but really a partner. Their team has always showed us their professionalism, expertise and business knowledge. Those are qualities that confirm that our choice of StackTeck was the right one. In terms of quality, there are no doubts. After millions of cycles the injection molds are in perfect shape and continue producing CSD 1881 Caps with the same quality that they have since the beginning. As a result of our excellent experience with StackTeck, we have gained new business and we hope to continue doing so in the future.”
The new moulds arrived at our facility last Friday, we trialed them yesterday and today and I’ve gotta say, I think my lead moulding technician is in love!! He is very impressed with the moulds and feels that they are much better than the local ones we have had made! I’ll send you some video of them running with IML ASAP.
This is our first experience with StackTeck moulds, and it has been very positive! I’d like to thank the StackTeck staff for all the help this year. The whole experience was easy and very professional… …and I’m sure the moulds will back this experience up. It’s a great thing to have an overseas mould supplier who can support the challenging projects we’re planning for the future.
The manufacturing cycle times of these molds are very fast, which indicates that the design of the molds and especially their cooling is excellent.
We have been very pleased with Stackteck support as a one-stop source for all of our medical molding applications. The design and build quality of Stackteck molds are proven in our experience. One of our many high cavitation stack molds from Stackteck has been in non-stop production since 2009 and operating to this date with no unplanned interruption. This speaks highly of Stackteck’s build quality.
“There are 3 elements that I can highlight from my experience of having worked with StackTeck: the order and cleanliness they maintain in their manufacturing plant, the integrity of the company as well as the diversity of customers that they deal with and finally, the human qualities of their team.
Based on my personal experience, I recommend StackTeck for the quality of its molds and the professionalism of its technical, accounting and engineering staff. After 25 years of being in this industry, I can say that it was a very pleasant experience to have found a company like StackTeck”
And at the booth of Wave Swiss, a maker of injection machines (waveimm.com), StackTeck ran its next-generation 1881 tamper-evident carbonated soft-drink cap mold with four cavities in 2.8 sec, cutting more than 1 sec off the previous speed. Cap weight was 2.15 g.
Kortec Inc. has recently achieved another industry first with its successful development and production of a turnkey manufacturing cell for producing high barrier food containers. The cell employs a StackTeck 64-cavity stack mold (2 x 32) that is co-injection molding multilayer thinwall plastic food containers with an inner and outer layer of PP, and a barrier layer of EVOH. The system currently produces parts at a rate of greater than 200 million parts per year at a cycle time of 7.5 seconds.
A 2 x 8 stack mold running thinwall, 16-oz dairy containers at what was said to be an "unprecedented" cycle time of 3.3 sec. It ran on an Engel all-electric e-speed 650T press.
After 5 years of operation, these molds show practically no wear or corrosion.
Working with Stackteck has provided me with an assurance of working with a team of thorough professionals. StackTeck's engineering strength combined with excellent customer care are among the many characteristics that have helped me with various projects.
Mold standardization and the scalability feature have been a success with some of our mold programs. In Engineering StackTeck is willing to undertake Analysis over and beyond basic services offered.
StackTeck handles and supports every project(small or large) with the same level of enthusiasm.
My favorite part of dealing with StackTeck is that I have never been refused a project by StackTeck. StackTeck's capability and the willingness to take risks have always provided me with assurance that has, in turn, helped me confidently take on challenges at my end.
We were assigned a project for high volume applications with a well known cosmetics firm while competing with other companies that offered the same manufactured part using a traditional injection blow mould. We were able to offer a high quality, efficient and low-cost solution. The 5 piece collapsing core technology enabled us to produce low weight parts with higher cavitation moulds, all with a 10 second cycle time versus lower cavitation and 18 second cycle time that the traditional injection blow molding offered. We were very pleased with StackTeck’s support and expertise, right from the product development stage to the design and manufacturing of the mold.
“Our moulds, hot runners, end-of-arm-tooling and Picool, a new, patented post mould cooling technology, are compatible with all major machine brands, at very competitive costs and industry leading performance”, Rick stated. “Our hot runner technologies are designed to reduce pressure drop, improve cavity-to-cavity balance, reduce colour changeover time, and generate lower AA levels than conventional designs, while virtually eliminating PET dust”, he added. The new moulds feature conformal cooling to improve productivity, while Picool speeds up cycle times.
If any part of the mold is damaged due to an operation mistake or any other accident, we then order it. When the part arrives, we mount it and the mold works perfectly. We don’t experience what has happened to us with other molds in which each cavity or core is different so that adjustments are needed for each spare.
This relates to a recent large project involving 5 container molds, 3 lid molds, and 6 robots.
We knew about the quality of StackTeck molds and therefore we expected that their robots would
match the quality requirements we had. We always look for molds and robots to be made with
StackTeck. We knew that if StackTeck took care of both, we would be in good hands.
StackTeck robots are very robust, of a technology and quality superior to what we were used
to with the previous supplier. We knew that the quality of the StackTeck robots was good and
so far we have not regretted it, we are very happy with the support of the entire team and it
seems very important that the entire team is involved, from senior managers to operations
people. We see that StackTeck's culture is very similar to ours and we really like that.
Contenedores IEM, S.A. de C.V. (IEMCO) is a manufacturer of medium and wide mouth PET jars and closures located in Monterrey México for the food and cosmetic industries with over 25 years of experience.
StackTeck has been our partner since 1999. We still have the first 4 cavity 110mm closure mold that was bought to TRADESCO (now StackTeck) this mold has been running for 16 years with +25 million cycles, still working perfectly.
We also have an 8 cavity 110mm closure mold that has more than 5 million cycles and is basically new, no problems at all.
Due to the excellent performance of their molds during the past years, we recently bought a 110mm Snap-On closure mold and we are in the process to buy a second 8 cavity 110mm closure mold.
All this has been achieved with the respective maintenance suggested by StackTeck.
Mold quality, materials, service and delivery time from StackTeck are exceptional.
"I wanted to give you an update on our new tools. Both molds are running faster cycles and our QC department has approved the parts. This is a big improvement for us….and will allow us to run the newest assembly equipment at speeds over 30% faster than our old equipment. We are very excited to be moving into production with these molds!"
Operating in high-volume, fast-cycle-time markets such as hospital and homecare products, where shipments are sent daily, Medline Industries Inc. (Mundelein, IL) takes its responsibility to customers very seriously. The manufacturer of medical/hospital supplies (think medicine cups and washbasins) has found that partnering with its suppliers is critical to its success. Jack Maze, VP of manufacturing at Medline's Dynacor Div., says his relationship with mold manufacturer StackTeck Systems Ltd. (Brampton, ON), molding machinery maker Husky Injection Molding Systems Ltd. (Bolton, ON), and CBW Automation (Fort Collins, CO) began more than a decade ago.
Every project begins with a cycle objective, Maze explains. The objective in the 1000-ton press was 5 seconds. StackTeck and Husky engineering teams examined the required parameters of the molding machine to see if, in fact, they could get to the cycle rate Maze required.
The automation of the project involved CBW, which participated early in the development and worked collaboratively with StackTeck and Husky to ensure that the automation could support the cycle goal. "To get in, grab the parts, and get out in 0.5 second or less requires special equipment and integration," says Jim Overbeeke, VP sales for CBW.
Partnerships like that of Medline, Husky, StackTeck, and CBW don't develop overnight. The three suppliers have worked together for many years with a variety of customers. A level of trust has been achieved that doesn't often happen when different suppliers are called upon to work together only intermittently during a program. "There's a lot we can do in a partnership situation with a good working relationship," says Tustin. "Everyone has to trust everyone else."
