It is understood that the two-color injection molding machine is used in multi-color and hard rubber encapsulated products, two-color TPU soles, two-color watch straps and other two-color and two-color handles. Although the two-color injection molding machine is equipped with a fully automatic inserting and removing system, it can completely realize unmanned operation. It has the advantages of a fully active inserting and removing system, a fully automated work flow, power, and low cost, but at the same time there are shortcomings that make it in The market is unable to hold a foothold. With the development of science and technology, the transformation of high-performance two-color injection molding machines has gradually become a trend.
