Mould Overmolding Medical Parts
Overmolding: Two kinds of plastic materials are not necessarily injection molded on the same injection molding machine, and are molded in two parts; after the product is taken out from a set of molds; it is placed in another set of molds for second injection. Therefore, in general, this molding process is usually completed by two sets of molds, and does not require a special two-color injection molding machine. The mold has the same mold structure as the single-shot injection, mainly by adjusting the flow rate of the injection parameters to control the material. The rubberized mold is mainly soft plastic hard rubber. The soft rubber is usually made of artificial rubber, TPU, TPR, etc. The hard rubber can be ABS, PC, PP, etc.
