Now the ever-changing consumer product models require good looks, fancy design, and also to quickly meet market demand. Designers generally design the house ware products for different purposes, in different parts of different materials to meet the needs of a particular environment, and to extend the product life and increase aesthetic and practical purpose. This practical design requirements will undoubtedly lead to the production technology also will be complicated, double color injection molding process is to be born of this trend.
 
Double color injection molding is make two different color material injected to one same mold, to make plastic parts presents regular or irregular pattern moire-like colors to enhance the plastic parts of practicality and aesthetics.
 
The double color mold core and cavity must match well after rotate 180°. When make the design, designer must check this action, as this has very high requirement of mold base positioning process.
 
The total thickness of clamp plate and A plate should not less than 170mm. When design the mold, must check customer’s injection molding machine max and min mold thickness and KO hole size.
 
When molding the products, it’s better to make the 1^st color a little bit bigger, so it can fit tighter when put it to the 2^nd color mold.
 
Avoid 2^nd injection melt flow makes 1^st color product deform, if this situation may happen, must rectify.
