There are many options available to thermoformers when it comes to plug assist materials. Wood, Nylon, tooling board, Syntactic Foam and Aluminum are among the most popular. The top-of-the-line options being Syntactic Foam and Aluminum. Though they are both excellent products, each has its pros and cons. Understanding these characteristics can help you make sure […]
2021 SPE Thermoforming Conference: Grand Rapids After a year of shutdowns, speculation and doubt, the thermoforming industry converged on Grand Rapids, MI for its bi-annual SPE Thermoforming Conference. In a normal year, the SPE conference serves as an opportunity to network with industry colleagues or perhaps see the unveiling of new products. This year however, […]
In March of 2020, the Coronavirus Pandemic hit the U.S. and changed life as we knew it. Face masks, social distancing, curbside pick-up, and food delivery became the new normal. As businesses were forced to close while Shelter-in-Place orders were issued, CMT remained open and operating above our average production level.
Why? Because we were classified as an “Essential Business”. But what makes CMT Materials “essential”? Read more
High wages, opportunity to grow, and countless entry level positions means jobs are being filled…right?
CMT was delighted to participate in another great SPE Thermoforming conference, held this year in Milwaukee, Wisconsin. Individual seminars were informative and well attended. With the unfortunate absence of Mark Strachan, we applaud the last-minute presenters that had the unenviable task of filling Mark’s shoes. Although Mark was deeply missed, the conference and adjunct presenters were spectacular in providing good information, making for productive seminars for all those in attendance.
CMT would like to recognize Ian Munnoch of MSA Components for the honor bestowed upon him as the 2019 SPE Outstanding Board Member of the Year. Ian was also one of the SPE members that gave a last-minute presentation on the science behind plug assist material and geometry.
A large swathe of the world’s plastic industry will arrive in Guangzhou, China in the month of May. Chinaplas is the second-largest plastics trade show and has the numbers to prove it, with over 180,000 visitors expected this year. CMT will be exhibiting in the US Pavilion, Hall 9.2, K-01 along with our partners at CMT East Asia. HYTAC materials, however, will be omnipresent in thermoforming booths across the entire show floor. European and Chinese machinery manufacturers will be displaying HYTAC B1X, FLX, FLXT and XTL plug assists for a variety of thermoformed products.
33rd edition of Chinaplas
May 21-24, 2019
China Import & Export Fair Complex, Pazhou, Guangzhou
We hope to see you there!
CMT Materials, the leading provider of plug-assist materials for the thermoforming industry, will showcase its range of HYTAC® syntactic foams at the upcoming K 2019 exhibition, which runs Oct. 16-23, in Düsseldorf, Germany. In Hall 3/G83, CMT Materials will highlight the latest innovative plug-assist materials – HYTAC C1R and HYTAC XTL – which have recently enjoyed strong market acceptance.
“We continue to see strong growth for copolymer and thermoplastic plug materials as the global plastics packaging market continues to evolve and grow throughout the world,” said Terry Woldorf, Managing Director for CMT Materials.
Along with many other variables affecting thermoforming output, the selection of plug assist material is critical. While syntactic foam is widely recognized as an ideal plug material, the choice of which specific grade to use is often left to “whatever we used last time.” Base level epoxy syntactic foams provide a great starting point into the technology and are widely used for a variety of applications. Looking beyond the basics, though, frequently offers significant performance improvements and cost savings. The attached case study provides detail about how one manufacturer gained a 10% increase in average thickness at a critical location (also highlighted as a whopping 41% increase in minimum thickness at the same point) when working with HYTAC-B1X, a thermoplastic syntactic foam, that offered greater friction due to its performance enhancing makeup. The attached article offers details.

Common problems encountered in the cut sheet thermoforming process include thin spots, webbing, crowning and plug/pusher mark off. Syntactic foam can be used in various ways with both positive and negative tooling to alleviate these issues. Syntactic plugs result in improved material distribution leading to opportunities for down-gauging. Compared to other common plug/pusher materials such as wood and felt-covered wood, syntactic foam results in minimal plug mark-off and improved plug durability. Attached article as published in The Thermoforming Quarterly provides details.
