Abstract

Different from the traditional physical mold injection, UV curing mold injection is a new manufacturing method which combines mold injection process and UV curing technology. On the basis of the traditional mold injection process the photochemical mold manufacturing process parameters had been studied, the effect of UV material temperature and the holding pressure on products precision had been analyzed and the quality of products microstructure morphology had been evaluated with cross section graph comparison method. Meanwhile, the micro-structure formability and replication accuracy of triangular edge cross section of miniature products had been researched. The experimental results shows that it is possible for UV curing mold injection to replace the thermoplastic mold injection. UV radiation intensity has a significant impact on formability and replication accuracy of microstructure; The UV system temperature has a certain influence on microstructure replication accuracy.
