High die quality has a significant effect.

Dalian mould processing and manufacturing technology is catching up with the international level, and enterprise management technology is in line with the international level. However, all employees of Chinese mould industry must study hard, firmly grasp the development direction of world mould technology, give full play to their subjective initiative, and create a better future with down-to-earth and full confidence. Computer Aided Engineering Analysis (CAE) technology for die and mould has been developed since 1990s.

Now it is also used in many enterprises. It has a significant effect on shortening the manufacturing cycle and improving the quality of the die. As far as most die and mould manufacturing enterprises are concerned, the future development direction should be to improve the level of numerical control and computerization, actively adopt high and new technology, and gradually move towards the integration of CAD/CAE/CAM information network technology. Paperless die manufacturing will gradually replace the traditional design and processing.

Whether the inserts are reasonable or not, the allowable degree of forming defects such as weld marks and shrinkage holes, whether there are post-processing such as painting, electroplating, bonding, drilling, etc. Choose plastic parts with high dimensional accuracy for analysis, to see whether the estimated forming tolerance is lower than the tolerance of plastic parts, whether the plastic parts can be formed to meet the requirements. In addition, we also need to know the plasticizing and forming process parameters of plastics.

The selection of moulding equipment depends on the type of moulding equipment, so we must be familiar with the performance, specifications and characteristics of various moulding equipment. Choosing the ideal die structure can make the die work to meet the technological and economic requirements of the plastic parts under the condition that the number of ideal cavity of the necessary forming equipment is absolutely dependent. The technological requirements of the plastic parts must be guaranteed to ensure the surface finish of the geometric shape and dimensional accuracy of the plastic parts. The low production efficiency and high die can work continuously for a long service life and save labor.
