Abstract
Paper for PC molding process and the status quo and development trend of the content on process. Blow molding to ensure a large number of molding products and economic production, to meet the growing needs of the people. Blow molding include the following: to soften the thermoplastic of the inflating parison to mold close to the closed cooling surface, the inflation of the parison solidification, the formation of hollow plastic products. Blow molding products, and with a shiny surface, or in the processing process, the products formed on the surface of engraving or carving patterns. Applicable to the majority of blow molding of plastic, so its in a variety of plastic molding processes account for a large advantage. As a new materials and new forming processes, blow molding process will be continuous development of the plastics industry to become the development trend of the future. Injection blow molding is an engineering technology, it is involved in the plastic and into a useful product to maintain the original performance. Injection blow molding is an important process conditions affect the plastics flow and cooling the temperature, pressure and the corresponding time in all. The main view of the current adverse moldings are to be analyzed to determine the reasons, in the molding machine, mold and provide
reference to the factors of raw materials so as to effectively control the selection of non-performing, lower production costs.
