For two-color plastic parts, in addition to a small number of two hard plastic two-color parts, most two-color plastic parts are composed of hard plastic parts and soft plastic parts. Hard plastic parts are generally made of PP, ABS, PC and other materials. Hard rubber part is generally made of PP, ABS, PC and other materials. Strength and hardness of this kind of hard glue material are good. When plastic part is assembled, it can meet strength and use requirements of plastic part itself, but for contact parts, hand feel and texture are relatively poor; soft rubber part is generally made of TPU, TPE, characteristics of this type of soft rubber material are that material strength and hardness are low, but material is soft and softness of hand is very good.

There are many plastic parts use PA+GF material, basic characteristics of PA+GF: self-lubricating, high strength. PA has good fluidity during molding, but molding shrinkage rate is large, resulting in poor product dimensional stability; Glass fiber has good heat resistance and is a high-grade insulating material with good insulation, which is suitable for production of thermal insulation and fireproof materials.

Main points of two color mold design of the parts with PA+GF material :

As long as GF material is added, front and rear mold cores need to be heat-treated materials (S136).
In the case that rear mold needs to be exactly same, machining accuracy and life are required to be higher than front mold core, so heat treatment hardness of front mold core is HRC48~52°, and heat treatment hardness of rear mold core HRC58~60°.
