Along with our country mold profession's high speed development, in addition each high performance engineering plastics's unceasing development, the plastic formation craft more and more uses in forming each performance requirement the product. The plastic formation craft including the injection molding, the pressure models, the blow molding, to push models and so on, the injection moldings are the methods which in the plastic processing uses most generally, is suitable in the complete thermoplastic and the partial thermosetting plastics. In the plastic products production process, mold's design is a quite important link, because mold's quality immediate influence models a quality, as well as price height. Therefore takes a mold designer, below should have the essential requirements: Mold's structure basic reasonable, can realize models a automatic drawing of patterns, based on the optimize structure, reduces the optimize structure and the cost as far as possible
