High fineness injection moulding technology and device
2009
A high fineness and no-weldlines injection moulding system was developed.The mould structure with following media path,the work principle of rapid heating and cooling device and temperature control device were presented.Analysis was made mainly on the constitution of high fineness panel shell and backboard of cores in fixed half,four types of media circulation paths and its switching ways.Experiments show that the system can effectively diminish surface defects like weld lines and flow mark and therefore improve the surface quality.The following spray painting process of products is no longer needed.
