- Abstract
The shrinkage which occurs in the plastic parts molded by injection is a very serious problem deu to these parts replaced the mechanical products that are manufactured into very small tolerances. In this study, the shrinkage of a I 20-3 plastic product which is affected from the injection parameters and the mold properties is experimentally investigated. In the experiments it was graphically obtained how the injection temperature, the injection pressure, the proportion of supplement material and the injection duration effect the shrinkage amount of a plastic part. I 668 polyethylene is selected for a supplement material. It was found that the shrinkage amount of plastic decreases with the increase the injection pressure and the duration.
