Advantages of a Bi-Color Injection Mould

A Bi-color Injection Mould has the advantage of being an easy process to operate and to control. This makes it perfect for plastic injection moulding and other manufacturing techniques. It is also very stable and reliable, meaning that it is able to withstand a lot of stress.

Two-color injection moulding combines two materials into one part, with different colors, textures, or characteristics. This can reduce costs of melting and post-processing, while providing excellent stability.

Bi-color injection molding plastic products have complex structures and are made with materials with high flow resistance, high thermal stability, and low melt viscosity. These parts require higher injection pressure, higher melt temperature, and longer mold runners.

In general, these parts can be made in regular patterns or in irregular moire colors. They can also be treated with surface finishes to serve technical needs or give the injection molded part a cosmetic look.

Depending on the type of plastic and the application, additives may be used to change properties such as color, lubricants, antimicrobials, and UV protectants. It is important to use additives that are compatible with the material being molded.

When designing a two-color injection mould, it is essential to consider the parting line. Parting lines need to be smooth. Otherwise, they will be rough, which will affect the lifetime of sliding parts. Moreover, they can cause drag marks.
