About this Solution:







Composite material molding is the process of molding two or more different materials into a single part.

There are several processes required to achieve this, such as two-shot plastic injection molding, insert injection molding, and insert compression molding. Each material has its own character that leads to different advantages and disadvantages. Composite material molding compounds the strengths of the materials and curbs its weaknesses.



Mistakes and problems, such as flow lines, sink marks, weld lines, shorts, and burn marks, etc., occur if every small step during the course of any of the dual-material molding procedures is not well designed and executed. Most mistakes are due to human error caused by inexperienced workers or by not using the right hardware and software tools.
