6. Sandwich injection molding
Sandwich injection molding, also known as sandwich injection molding or surface-core processing, allows a material to be completely injected into the surface material. It can be used for refilling, hardness and toughness, and different requirements in the adjustment of the center of gravity of the product. It improves the performance requirements of the product and ensures the appearance of the surface.
An internationally renowned sanitary ware company introduced sandwich injection molding and optimized the addition of secondary materials, saving 35% of raw materials a year. At the same time, it can make rational use of the secondary materials that could not be added, which greatly enhances the competitiveness of the enterprise in terms of manufacturing costs.
7. Cube mold
The cube mold can fully utilize the time of mold opening for cooling, which greatly increases the production efficiency and increases the capacity of the equipment to the limit.
It has outstanding advantages in the production of thin-walled and high-volume products. The only drawback is the extremely high cost of the mold input, and the need for some custom modifications to the equipment.
In the current multi-color molding process, the advantages of the cube mold in terms of efficiency are unparalleled. This process fully utilizes the opening and closing mode, ejection time, etc. in the molding cycle, and has outstanding advantages in mass production.
