Two-color and multi-color injection molding has developed rapidly and been widely used in automobiles, medical products, packaging, electronic products, household appliances, toys, homes decoration, electric tools, daily necessities, portable wearable products and other fields.
Various innovative technologies of two-color and multi-color molding are constantly emerging, and two-color or multi-color injection molding technology has become the preferred direction for processing many high-end products.
Multi-color injection molding has gradually developed into a mainstream technology in the injection processing market, and more and more high-quality and high value-added products are processed by multi-color and multi-material molding technology.
After years of development, two-color and multi-color injection molding is not only limited to rotary machine molding, but has expanded many fixed branches, among which there are sandwich injection molding, cube mold and liquid silicon multi-color injection, which are also popular trends in recent years.
Sandwich injection molding consumes secondary materials, and twin screws are responsible for injection and independent pressure maintaining, thus increasing cycle and reducing energy consumption, which is a relatively environmentally
friendly injection molding process at present.
Cubic die has unique advantages in efficiency, which is very suitable for thin-walled products such as bottle caps and has excellent advantages in mass production products.
Liquid silicon injection has become a hot new product selection scheme, because it combines the excellent performance of LSR such as high and low temperature resistance and corrosion resistance, and has the excellent characteristics of stability and precision brought by injection molding parts.
