Difference Between Plastic Mould And Two-color Mould.

Difference between plastic mould and two-color mould

1. Two-color mold: a mold in which two kinds of plastic materials are injected on the same injection machine and molded twice, but the product is only molded once. Generally, this molding process is also called double injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine. Two-color mold can make two resins and colors with different characteristics into a single two-color product, which can reduce the assembly and post-treatment of molded products. Save the cost of dissolving and printing, increase the aesthetic visual effect of products, and enhance the grade and added value of products. Not only has the function of anti-skid and increasing friction, but also the flexible resin material makes it more ergonomic and feels better. Two-color injection molding products have high quality stability, easy control of product deformation, short molding cycle, high yield, 7% lower loss than encapsulated injection molding, and 20%-30% lower manufacturing cost than encapsulated injection molding.

2. Plastic mold (secondary molding): two kinds of plastic materials are not necessarily injected on the same injection molding machine, and are 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. Therefore, generally, this molding process is usually completed by two sets of molds, and there is no need for a special two-color injection molding machine. Its mold structure is the same as that of a single-color injection mold, and it mainly depends on adjusting the flow rate of injection parameters to control the combination point of materials. The plastic mold mainly covers hard rubber with soft rubber, among which artificial rubber, TPU and TPR are commonly used for soft rubber, and ABS, PC and PP are used for hard rubber.

Eight common injection mold structure classification One. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated, so as to take out the plastic parts, which is called single parting surface mold, also called double-plate mold. It is the simplest and most basic form of injection mold, which can be designed as single-cavity injection mold or multi-cavity injection mold according to the need, and is the

The difference between injection moulds and plastic moulds Many people can’t tell the difference between injection molds and plastic molds, and many people even think that they are the same kind of molds, just called different. Although injection molds and plastic molds are both molds, but there is a difference between them. Want to figure out the difference between the two, first and Xiaobian together to understand what is injection mold, what is plastic mold.
