Thermoplastic Resins for Insert Molding and Two Shot Molding
At LSI, we process virtually all thermoplastic engineering grade resins. There are many varieties of each of these materials with engineered fillers including glass, stainless steel fiber, carbon fiber, talc, and lubricants. We also mold many commodity thermoplastic resins.
Thermoplastic Elastomers (TPE's) are often used with the Insert Molding and Two-Shot molding processes to obtain the soft-touch, shock absorption features and molded-on/over gaskets. When overmolding a plastic substrate, material compatibility is essential between the selected TPE and the substrate to obtain cohesion between the materials during the overmolding process, if so desired.
Design Assistance and Prototyping for Plastic Injection Molding
Early engagement with LSI's engineering staff is necessary to achieve a mutually successful project. Our team of engineering professionals assist our customers with optimizing a products design using design practices that best facilitate the plastic injection molding process.
Careful consideration of the desired plastic resin, geometry/shape and features of the designed part, mold material and mechanics must all be taken into account when planning your plastic injection molding project. Together with our customers, a product design is evolved to produce the most cost-efficient and robust part that meets your requirements.
