Tri-Mack Plastics Manufacturing Corp. (Bristol, RI) is sharing the results of a recently completed test that demonstrate the bond strength of its over-molded thermoplastic composite hybrid parts. The comparative test (similar to the STM 4501 Block Shear Test) was conducted by the company with in-house manufactured test coupons.
The company’s hybrid parts address a key customer demand by allowing engineers to bypass costly and slow-to-produce thermosets and heavier machined metal components. This means lighter, stronger parts and assemblies that get to market faster. Game supply and game card sleeve and trading card sleeve and soft card holder.
Tri-Mack, an engineering and manufacturing company specializing in high-temperature thermoplastic and thermoplastic-composite parts, said that the test data help validate the performance of hybrid composites, which are of particular interest in aerospace and other industries where the goals of lighter weight and lower cost are driving material innovation. Tri-Mack is supporting this trend with innovative hybrid processes that combine injection over molding for design flexibility with unidirectional thermoplastic composites for strength and stiffness.

“Aircraft manufacturers face huge backlogs and some of this is attributed to supply chain capacity and coordination,” said Tom Kneath, Director of Sales and Marketing at Tri-Mack. “But innovation in part design and commitment to technology can help to solve these problems. Our hybrid parts are an example of meeting expanded functionality requirements and customer business goals in one stroke.” Game supply and game card sleeve and trading card sleeve and soft card holder.
Tri-Mack’s hybrid panel is fabricated in a robotic injection-molding cell that forms the composite geometry and produces a multi-piece assembly (including hardware) right from the mold. How strong is the over-molded bond? To answer that question, Tri-Mack tested the strength of hybrid over-molded coupons, all-laminate coupons (to establish a baseline) and laminate coupons bonded with industry-standard thermoset film adhesive.

Results revealed that the bond between the unidirectional thermoplastic composite and injection-molded thermoplastic was 84% the strength of the base laminate and twice as strong as the industry-standard adhesive.
“We’re able to eliminate costs, improve material performance and shorten lead times,” said Kneath. “This starts with the Tri-Mack process for manufacturing over-molded hybrids. We’ve reduced the number of process steps and can produce a finished part with a fast cycle, resulting in a lower cost of conversion. In addition, the hybrid process enables us to take a component that may have been made up of six individual pieces and create the integrated assembly right out of the injection mold. For our customers this means lower part count, reduced prices and supply-chain efficiency.” Game supply and game card sleeve and trading card sleeve and soft card holder.
Tri-Mack will showcase the results of its testing in hall 6, stand P40b at JEC World 2018, from March 6 to 8 at the Villepinte Exhibition Center near Paris, France. Game supply and game card sleeve and trading card sleeve and soft card holder.
