ZSD’s Thoughts on Double-color Injection Molding Technology Processes

Double-color molding is the one available process for managing product molding with two different materials and colors, using simultaneous molding processes in the same injection machine to output a single unit. Double-color molding is now widely used for electronic parts, electric tools, medical parts, home appliances, toys and almost all areas of plastic products. Center-stack Rotary Double-shot is one hot double-color molding method seen in recent years, differing from common double-color rotary injection molding, especially in the automotive injection molding sector, for products such as two-color door panels, lights and so on. The development of double-color mold manufacture and molding process, double-color or multi-color injection machines and double-color material is advancing rapidly, with several advantages:

Simplification of the assembly and post-processing process, saving costs in melting and printing, while increasingartistry and raising the products’ level and added value.

With anti-slip and increased friction functions, flexible resin is more ergonomic and feels better.

Increased quality stability, with easier control of product deformation, and a high yield with short cycle time. Comparing with overmolding, there is 7% less loss and a 20%-30% lower product manufacturing cost can be achieved.
