What is the difference between the two-color mold and the overmolding before? Two-color mold: Two plastic materials are injected on the same injection molding machine and molded twice, but the product is only molded once. The molding processing speed is fast, the processed product has a more beautiful appearance, and it can process precise two-color or even multi-color products. shortcoming—Two-color molds require special two-color injection molding machines, but the cost of two-color injection molding machines is much more expensive than ordinary injection molding machines.

Overmolding: 1. It is not necessarily injected on the same injection molding machine, and it is molded twice; after the product is taken out of one set of molds, it is put into another set of molds for the second injection molding. 2. It can be molded and processed by ordinary injection molding machines, and the investment in equipment is relatively small. 3. It is not suitable for precision injection molding of double-material and multi-material injection products; the molding processing cycle is relatively long, and the production efficiency is lower than that of two-color molds.
