Hi-Tech Mold & Tool, Inc., a provider of advanced engineered thermoplastic part manufacturing for medical, aerospace, and consumer products and industrial equipment, offers part design assistance, mold flow analysis, tool design, and engineering support to best suit its customers' needs, according to company representatives.

The company's expertise in advanced materials, tooling, and the development of proprietary manufacturing processes for high-temperature molding gives customers a unique resource for cost-effective metal substitution, said company program manager Ann Fyfe, in a written response. Hi-Tech ( works with its customers at early stages of design to assist with design optimization for best manufacturability, she said.

"One of Hi-Tech's strengths is assisting in part design, material recommendation, and manufacturing for best costs. Customers choose Hi-Tech for our engineering/design support, quality systems, and expertise with high-temperature materials. Also, we are a full-service molder that offers machining to tight tolerances and final assemblies and testing," Fyfe said in a written response.

Hi-Tech's machining of thermoplastic components allows the company to achieve dimensions that cannot be molded. Its experience in tool building has allowed the company to demonstrate the capability of holding profile tolerance of +/- 0.001" over a complex geometry.

The company can review metal part designs and offer cost savings through re-design in engineered thermoplastics. Its specialty is high-performance, high-temperature engineering thermoplastics, according to Fyfe. "Hi-Tech's experience with material and alternate processes make us an ideal partner on complex engineering problems with metal to plastic conversions," she said.

An example of an engineering problem that the company faced involved molding and began with a long, clear part that needed to have a light transmission between 30 percent and 40 percent. Hi-Tech worked with material suppliers to find the best, clearest material for the applications, and using its expertise with injection molding, developed an optimal, repeatable process to ensure the best results, Fyfe said.

Another challenge involved a secondary operation in which the company had an over mold where the TPE (elastomer) was resistant to chemicals and needed to be pad printed. The ink was not adhering due to the resistance, but through research and trial, Hi-Tech developed a method to enable the ink to bond to the TPE using plasma treatment, ovens, and multi-part ink.

The company, based in Pittsfield, Mass., is ISO 9001, AS9100, and ISO 13485 certified and has engineers, tool makers, and processors with more than 30 years of experience, which Fyfe said is part of the company's key to success.
