1. Don't just focus on product design and neglect Mold manufacturing: Some users often focus only on product development and development in the initial stage when developing products or trial production of new products, neglecting communication with mold manufacturing units. After the initial determination of the product design plan, contacting the mold manufacturer in advance has the following three benefits: (1) To ensure that the designed product has a good forming process and will not modify the finalized design due to the difficulty of processing the parts. (2) The mold manufacturer can make design preparations in advance to prevent hasty and thoughtless considerations from affecting the construction period. (3) To produce high-quality molds, only through close cooperation between supply and demand can costs be reduced and cycles shortened. 
2. Don't just look at the price, consider quality, cycle, and service from all aspects:
(1) There are many types of molds. Select different types of molds for forming based on different requirements such as part material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, and economy. (2) High precision molds require the use of high-precision CNC machine tools for processing, and there are strict requirements for mold materials and forming processes. CAD/CAE/CAM mold technology is also needed for design and analysis. (3) Due to special requirements during molding, some parts require the use of hot runner, gas assisted molding, nitrogen cylinder and other processes in the mold. (4) Manufacturers should have CNC, electric spark, wire cutting machine tools and CNC profiling milling equipment, high-precision grinding machines, high-precision three coordinate measuring instruments, computer design and related software, etc. (5) Generally, large stamping molds (such as automotive cover parts molds) should consider whether the machine tool has a pressing edge mechanism, multi station progressive, etc. In addition to stamping tonnage, consideration should also be given to punching times, feeding devices, machine tools, and mold protection devices. (6) The manufacturing methods and processes of the above-mentioned molds are not possessed and mastered by every enterprise. When choosing a collaborative manufacturer, it is important to understand its processing capabilities, not only based on hardware equipment, but also combined with management level, processing experience, and technical strength. 7) For the same set of molds, there may be significant differences in quotations from different manufacturers. You should not pay more than the value of the mold, nor should you pay less than the cost of the mold. Mold manufacturers, like you, need to achieve reasonable profits in their business. Customizing a set of molds with a much lower quotation would be the beginning of trouble. Users must start from their own requirements and comprehensively measure. 3. Avoid multi head collaboration and strive to integrate mold production and product processing as much as possible. The above is the design precautions for plastic molds compiled by the editor.
