1. Two color injection molding advantages

Two color mold can be two different characteristics of resin and color, into a single two color product, can reduce the formation of molding products and post-processing engineering. Save the cost of melting and printing, increase the aesthetic visual effect of products, enhance the grade and added value of products. Not only has the function of anti-skid, increase friction, flexible resin material makes it more ergonomic, feel better. Two-color injection molding products have high quality stability, easy control of product deformation, short molding cycle, high output, loss is 7% lower than plastic injection molding, product manufacturing cost is 20%-30% lower than plastic.

2. Two color forming principle

Two-color injection molding usually refers to two colors or different kinds of plastic molding, because the two groups of two-color machine injection unit and nozzle is independent separate, so the color of the finished product is mostly two-color distinct, not mixed together. The biggest difference between the two color injection machine and the general injection machine is the design of the moving template of the injection unit machine. Generally speaking, the two-color machine has two separate groups of injection units, and the injection machine generally has only one group of injection units. Two groups of injection unit configuration with the design of various manufacturers and have a variety of forms, as for the design of the active template is to provide rotation mechanism, generally common design such as the increase of the rotary plate or shaft mechanism, in order to provide 180° reciprocating rotation function, so that the mold cycle alternating action. Some special two-color molds do not require a turntable or shaft mechanism, and the mold for sliding alternately or horizontal rotation.
