What are the basic knowledge of plastic molds and injection molds?
The innovation of plastic mold processing technology, the widespread application of various new mold materials, and the standardization and specialization of mold parts force us to speed up the design speed and adapt to the development of molds.
The improvement of speed requires the design section to be completed in about 3 days; the improvement of plastic mold precision requires that the processing methods of each part should be clearly considered during the design process, and the processing methods with high precision and low processing cost should be adopted as much as possible. The improvement of precision and speed are common. The improvement of speed must require the improvement of precision; the improvement of precision must lead to the improvement of speed.
