Micro injection molding of polymers – technology, tools and machines

Polimery 2007, No 3, 179


Summary

Two basic methods of micro-devices' manufacturing: hot embossing and micro injection molding were characterized, the latter method was stressed. The stages of technological process and the course of micro injection molding of polymers were described. The constructions of forming tools and the processing requirements were presented. The techniques of fabrication of mold inserts, such as micromachining, electro-erosion machining and especially LIGA process (Fig. 2), were described. The differences between micro injection molding and conventional injection molding were pointed.


Key words: micro injection molding, polymers, mold inserts
