1.
Two-color Injection Molding, also known as two-color
Mold injection molding, is to inject two plastic materials on the same injection molding machine and mold them in two times, but the mold for which the product is only released once is usually completed by a set of molds and requires a special two-color injection molding machine. Injection molding machine.
The same back mold, different front mold, high production efficiency, good product quality, suitable for mass production.
2. Secondary injection molding is also called overmolding
injection molding. Two plastic materials are not necessarily injected on the same injection molding machine, but are molded in two times; after the product is taken out from one set of molds, it is put into another set of molds. Secondary injection molding is performed. Therefore, in general, this molding process is usually completed by two sets of molds, without the need for a special two-color injection molding machine.
Secondary injection molding is to first take out a part of the product after injection molding, and then put it into another injection molding machine for injection molding. The efficiency will be slower and the cost will be higher, which is suitable for small batch production.
