Multi Shot Molding

Different plastic materials and colors are used to create multi shot injection molding parts. In the process of injection molding, different materials must be tightly differentiated from one to another and cannot penetrate one another, like a Heart Rate Band.

Different injection molding goods need to match different types of plastic materials in addition to materials with diverse hues, such as:

1) The majority of the time, thermoplastic material and thermoplastic elastomer (such as TUE, TPU, etc.) are used to create products that combine soft and hard components. The product may have a rigid, corrosion-resistant matrix as a result of this combination, as well as a sealed anti-seismic or more pleasant feel.

2) Items that incorporate Liquid Silicone Rubber (LSR). Since LSR has greater temperature resistance and mechanical qualities than thermoplastic elastomer, it is being used more frequently in multi material injection molding processes.

MATERIALS OPTION OF

CN's Multi-Shot Tooling

Because it directly affects a number of factors, such as mold manufacturing technique, mold life, the quality of plastic components made from molds, and mold processing costs, the choice of mold materials is an important stage in the design and manufacture of molds.

In general, between 150 and 200 °C in both temperature and pressure are needed to operate plastic molds. Taking into account the various usage scenarios and processing methods of plastic mold, the following are the fundamental performance characteristics of steel for plastic mold that CN Mould & Plastic Limited selected:
