Plastic Injection Molding

Plastic injection molding is a manufacturing process to obtain molded products by injecting plastic materials molten by heat into a mold, and then cooling and form a part of the shape of the mold.

Overmold Injection Molding

Overmolding is a plastic injection molding process which is the good way for producing multi-material parts with some unique properties. To help understand how overmolding is used in parts fabrication, here are some examples of how the process is applied:

A )Over Plastic/ 2K Injection Molding– It’s possible to overmold plastic onto plastic. Firstly, more rigid plastic component is molded or machined and then the more durable plastic part is molded over the previous plastic part.

B )Over Metals/ Inserts overmolding.– Overmolding plastic onto metal is often used for making plastic handles, shells or electronic components etc. It’s a similar process with over Plastic, in which plastic is molded over the metal part.
