Principle Analysis of Over Moulding Technology for Injection Mold

• 

In the past 10 years, over mouldingtechnology has completely changed the aesthetic standards, design ideas and functional requirements of consumer goods. Medical device manufacturers also recognize the potential advantages of the technology and continue to expand its application in the medical field. Secondary injection moulding technology is famous for creating "soft surface". But it also has many other functions, such as ergonomic design, two-color appearance, brand identification and feature improvement. Using this technology, we can increase the functions of products (such as noise reduction, shock absorption, waterproofing, collision avoidance) and added value. Secondary injection, like co-injection, double injection and sandwich injection, belongs to multi-material injection technology. The basic idea of multi-material injection moulding is to combine two or more materials with different characteristics to improve product value. In this paper, the first kind of injection material is called base material or base material, and the second kind of injection material is called cover material.

In the Over Moulding process, the covering material is injected into the upper, lower, surrounding or inner parts of the substrate to form a complete component. This process can be accomplished by multiple injection moulding or embedded injection moulding. The commonly used covering material is elastic resin.
