What Should Vietnamese Plastic Manufacturers Pay Attention to in Mold Design Requirements?

Vietnamese plastic manufacturers should pay attention to the following requirements in mold design. First, ensure a rational mold structure to meet the molding needs of plastic parts. The materials selected should possess high wear resistance and corrosion resistance to extend the mold’s service life.

Thorough Analysis of Plastic Part Structure and Technical Requirements: The structure of a plastic part determines the complexity of the injection mold, while its technical requirements (such as dimensional accuracy and surface roughness) impact the difficulty of mold manufacturing and forming processes. For any special requirements or unreasonable structural shapes that do not meet injection molding standards, improved design solutions must be proposed to avoid adding complexity to mold design and manufacturing.

Familiarity with Injection Molding Machine Specifications: The specifications of the injection molding machine directly limit the mold size and the range of products that can be molded.

Understanding the Processing and Technological Properties of Plastics: This includes knowledge of the plastic melt’s flow characteristics, flow distance, flow resistance in the runners and cavities, air release, crystallization and potential internal stress, as well as cooling shrinkage and temperature requirements.

Consider Mold Design and Manufacturing: Choose a suitable mold structure by reviewing plastic part drawings and technical requirements, and study the appropriate molding methods and equipment. Gather ample feedback to ensure that the mold design is reasonable, reliable in quality, and easy to operate. If necessary, request modifications to the plastic part drawings, but ensure customer approval is obtained.
