"Mould is the mother of industry" has been well known. The importance of mould has been recognized by people day by day. Mould design and manufacturing technology have made considerable progress.

The innovation of die processing technology, the wide application of various new die materials, and the standardization and specialization of die parts force us to design faster and adapt to the development of die.

The improvement of speed requires that the design section can be completed to the post-processing section in about 3 days, and the improvement of accuracy requires that the processing methods of each part should be considered clearly in the design process, and the processing methods with high accuracy and low processing cost should be adopted as far as possible.

The improvement of accuracy and speed is mutually reinforcing. The improvement of speed inevitably requires the improvement of accuracy, and the improvement of accuracy inevitably drives the improvement of speed.
