Injection is a themal plastic process that are molten plastics to push in the mold by a injection machine with high pressure and high temperature, then cooling to have products.
This process use to create the products with high precission standarts, high quality and applications in many areas from small parts to big parts. This is one of the most popular plastic technology.
The quality of molded part is largely determined by the performance of the injection molding machine as well as by the precision and the function of the mold. It is also influenced greatly by the molding metarial. Various combined factors involve molding production, a high quality molding will be achieved upon good condition of all elements.
2. The factors effecting to quality of products
