The structure of two-color injection molded products is very different from that of ordinary plastic products. Due to the use of two different materials for injection molding, the products have two different properties and characteristics, which are fundamentally different from ordinary injection molded products; Before injection molding, a detailed two-color injection product structure design is required, and the compatibility of the two materials should be fully considered. 1. The front mold cavity structure of the two sets of molds A and B is the same, but the back mold is different; 2, if the parts A and B are combined with each other, the processes between them will be affected by each other;
The concept of color mold cavity-the plastic part cavity of part A is formed as a single color, and then part B is produced; 4, there are double-layer thimble plates and 'stepped' ejector pin holes-ejected when forming part A Only the front plate PET preform mould (nozzle) is topped, but the back plate (product) does not move. After rotating 180 degrees, part B is formed and then tops the back plate (product). Design the mixing ratio and connection method of the two materials in combination with the function and use environment of the plastic product, analyze the complexity of the process in detail, and consider the design of the use strength, so that the two-color injection product can meet the relevant material standards And requirements.
Plastic Mould Factory has two-color injection molding, strict quality control procedures, from the beginning of the two-color mold raw materials to the final delivery, every link is strictly controlled, so that the two-color mold design is reasonable, production accuracy, two-color mold life and injection product quality We can produce high-quality two-color molds and two-color injection products for you.
