Mold is an important process equipment for the production of various industrial products. With the rapid development of the plastic industry and the promotion and application of plastic products in industrial sectors such as aviation, aerospace, electronics, machinery, ships and automobiles, the requirements for molds are becoming more and more High, the traditional mold design method can no longer meet the requirements of product upgrading and quality improvement. Computer-aided engineering (CAE) technology has become the most effective way for these weak links in plastic product development, mold design and product processing. Compared with traditional mold design, CAE technology has great advantages in terms of improving productivity, ensuring product quality, or reducing costs and labor intensity.
Moldflow, a listed company in the United States, is a professional injection molding CAE software and consulting company. Since it released the world’s first set of flow analysis software in 1976, it has been leading the plastic molding CAE software market. In recent years, it has been widely used in the fields of automobiles, home appliances, electronic communications, chemicals and daily necessities. CAE technology can be used to analyze the entire injection molding process on the computer before mold processing, and accurately predict the filling, pressure holding and cooling of the melt, as well as the stress distribution in the product, molecular and fiber orientation distribution, and shrinkage of the product And warping deformation, etc., so that the designer can find the problem as soon as possible, and modify the part and mold design in time, instead of waiting for the mold to be repaired after the mold is tested. This is not only a breakthrough in traditional mold design methods, but also has great technical and economic significance for reducing or even avoiding mold repair and scrap, improving product quality and reducing costs.
The design of plastic molds requires not only CAD technology, but also CAE technology. This is an inevitable trend of development. Injection molding is divided into two phases, the development/design phase (including product design, mold design, and mold manufacturing) and the production phase (including material purchase, mold trial, and molding). The traditional injection molding method is to design the mold by experience and intuition before the official production. After the mold is assembled, it usually needs several trial molds. Mold design, which will inevitably increase production costs and prolong product development cycle. The use of CAE technology can completely replace the trial mold. CAE technology provides a complete solution from product design to production. Before the mold is manufactured, it can predict the entire molding process of the plastic melt in the cavity, helping to study and judge potential problems, and effectively Prevent problems from happening, greatly shorten the development cycle and reduce production costs. In recent years, the importance of CAE technology in the field of injection molding has increased day by day, and the use of CAE technology can comprehensively solve the problems that arise in the injection molding process.
