Injection molds are important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the requirements for molds are becoming more and more important. The higher comes, the traditional mold design methods can no longer meet today's requirements. Compared with traditional mold design, computer-aided engineering (CAE) technology is either in terms of improving productivity, ensuring product quality, or reducing costs and reducing labor intensity. In all aspects, they have great advantages.
