Our products provide:
We combine high-quality, industry-proven syntactic foam products with superior problem-solving skills and top-notch customer service to optimize the performance of thermoforming tools. Whether it’s off-the-shelf plug assists or custom sized solutions, CMT stands ready to help.
HYTAC® Plug Assist Materials – the CMT Materials plug assist family of products – allows thermoformers, tool makers, and machine builders to get more efficient material distribution with:
HYTAC products are available in a wide variety of sizes in rod, sheet, and block. See our HYTAC syntactic foam plug assist products in use in the HYTAC photo gallery.
There are four types of HYTAC materials:
HYVAC® is a fast and economical way to hold contoured parts in place during a trimming or assembly operation. It is also gaining popularity as a quick and easy-to-use go/no-go QC fixture to check formed part sizing. HYVAC comes as a three-part kit of resin, catalyst and fiber-reinforced spheres which can be easily mixed and poured into a formed part or other mold. Following an overnight room temperature or low temperature oven cure, the fixture is removed from the part/mold and ready for use. Vacuum may be pulled directly through the material to provide an effective hold-down fixture that may be installed on an automated or manual router system.
CTB and REN Shape® tooling and modeling board. Vacuum formers and thermoformers use these products for prototype and low volume production molds when forming in applications where metal molds do not make sense due to time or cost considerations. CMT can help in selecting the proper board material for specific forming applications considering factors such as surface quality, ease in machining, tool durability, and forming temperature. See our Comparison List for details on all available tool board products.
METAPOR® is a composite material consisting of two major components. Different granules, such as aluminium or ceramic materials, and binders are currently used in thermoforming tools. The material is air-permeable over the entire surface, due to its micro-porous structure. In contrast to sintered materials, the pores are not closed off after machining. The numerous advantages are useful in the thermoforming industry as well as for vacuum clamping and air cushion devices. Design flexibility is enhanced because micro-vents are an integral part of the complete surface. The material‘s inherent properties eliminate the need to design and manufacture complex venting systems. For ideas, see the METAPOR photo gallery.
