The manufacturer produces 7.5 million cases per year, and was using liquid injection molded (LIM) silicone for this part. However, the silicone was sticking to the mold and inner workings of the molding machine. This not only caused a high scrap rate, but also led to frequent interruptions in the automated process so that the mold and machine could be cleaned.

Achieve complex designs without expensive tooling – Gravi-Tech material can be injection molded into unique part shapes utilizing lower cost molds made of P20 or H13 steel. Add weight while simplifying your processing steps – Simplify your manufacturing process by injection molding a weighted, finished part in one step rather than adding a metal weight. Reduce the number of parts – By injection molding Gravi-Tech material, you will no longer need to assemble multiple parts to achieve added weight.

Overmolding integrates Polystrand tapes and multi- ply laminates into traditional thermoplastic molding processes, such as injection and compression molding, to create locally-reinforced, molded components. Read the Rome Snowboard Binding Case Study bit.ly/34PG0a6 Incorporating Polystrand CFRTP reinforcement in molded thermoplastic components combines the design flexibility and fast cycle times of traditional molding with the strength, stiffness, and lightweighting benefits that composites offer, all with the use of standard processing equipment.

For these reasons, it is often required to over mold TPE immediately after molding the nylon substrate. NYLON MOLDING PROCESS Bonding is also affected by mold design and nylon molding conditions. INSERT MOLDING Insert molding data is reported in Table 3 and Figures 4 through 9.
