Quality blow mold company supplier: Blow molding is a process in which a hollow product formed by the expansion of a hot-melt plastic tube closed in a mold by means of gas pressure. The blow molding process was used to produce LDPE vials in World War II. In the 1950s, with the birth of HDPE materials and the development of blow molding machines, the blow molding process was widely used and the technology was upgraded. According to the different plastic blank tubes, it can be divided into extrusion blow molding, injection blow molding, stretch blow molding and multi-layer blow molding. Compression molding process A manufacturing process for molding polymers such as thermosetting plastics, thermoplastics, elastomers, rubber and plastic materials, and natural rubber. For example: children’s pacifiers, sealing rubber rings, power insulation parts, electrical enclosures, etc. Find a lot more information on blow molding china.
Plastic injection molds are made of mold steel, aluminum alloy and other materials. It is divided into a fixed end and a sliding end. Generally, the sliding end has a feed injection hole, a support plate, an ejector box, an ejector rod, an ejector pin, an ejector plate and other accessories. Mold manufacturing and design is a professional and challenging job, which can directly represent whether a manufacturer has the technical ability to provide a series of solutions for high-precision products.
The loss of raw materials is small and will not cause too much loss (usually 2% to 5% of the product quality). The internal stress of the product is very low, and the warpage deformation is also very small, and the mechanical properties are relatively stable. The wear of the mold cavity is small, and the maintenance cost of the mold is low. The cost of molding equipment is low, and the mold structure is simpler, and the manufacturing cost is usually lower than that of injection molds or transfer molding molds. Larger flat products can be formed. The size of the products that can be formed by molding is only determined by the clamping force of the existing molding press and the size of the template.

Rigid plastic overmolding process: After the internal base material is made of rigid plastic injection molding, another type of steel plastic is wrapped around the base material through an overmolding mold. The color of the material can be customized, but the material compatibility limit should be consulted. Otherwise, cavities or cracks will occur. Rubber overmolding plastic: The internal base material is made of steel plastic. After molding, the rubber material or TPE material is wrapped on the surface of the base material. The product presents the softness of rubber and can play a role in wear resistance and non-slip, such as: toothbrush handles, electric tool handles, etc. Read additional information on https://www.china-plasticparts.com/.
