Thermoplastic composite overmolding—important technology in overmolding, in which thermoplastic overmolding composite laminates are thermoformed and then plastic injection overmolding.
Features of thermoplastic composite overmolding:
Overmolding of thermoplastic composites is a hybrid process that combines thermoforming of a continuous fiber reinforced thermoplastic laminate with an injection or compression molding process. The process allows for complex parts with high structural performance due to the continuous fibers, providing high specific stiffnes and strength. Further advantages are the potential for a high level of function integration, net shape manufacturing and large series production in an automated process.
The process consists of the melting and forming of a composite laminate, which is subsequently over injected with a polymer that is compatible with the polymer matrix of the composite and which may be reinforced with short fibers.
Material selection:
TPE can be used for cladding and two-color injection molding. As a soft material, TPE is usually matched with hard materials, mainly plastics, metals, and fabrics. TPE can be firmly bonded with some commonly used plastics PP, GPPS, HIPS, ABS and engineering plastics PC, PC/ABS, PA and their modified materials. TPE + cloth is mainly used for luggage products. The process is the same as that of metal cladding, usually false cladding. And the real coating molding in secondary injection molding and double - color injection molding is more common.
TPE can be firmly bonded with some commonly used plastics PP, GPPS, HIPS, ABS and engineering plastics PC, PC/ABS, PA and their modified materials. Adhesion between TPE and POM is still a problem in the current elastomer industry. Since the solubility parameter SP(22.6) of POM differs greatly from that of TPE (7.2-7.6), the two materials are incompatible with each other, and no suitable compatibilizer has been found to promote the bonding of the two materials.
