Injection mold supplier 2024: In the blow molding process, the billet is formed by the head under low pressure, and is blown under low pressure, because the residual stress of the product is small, and the strain properties such as stretching, impact, bending and environment need to be improved, so its use performance is higher. There is no waste generated in the processing of blow molded products, which can well control the wall thickness of the products and the dispersion of the materials, and the fine neck products have high molding accuracy, and the surface of the products is smooth, and can be economically produced in small batches. And the products have no seams, high bottom strength, accurate mouth size, and blow molded products have high stiffness, high strength, high hardness, creep resistance, gloss and moisture permeability, good oil, fat, acid and alkali resistance, and a very wide range of use.

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.

Generally, overmolding is an injection molding technology that effectively reduces costs and is widely used, and requires rich manufacturing experience and high mold manufacturing standards. It can quickly reduce the cost of secondary assembly of traditional plastic parts, as well as applications that do not require harmful glue, and can achieve stable quality, high efficiency, and reduce the risk of defective products during mass production.

The process of rotational molding is much simpler than the manufacturing process that relies on pressure molding, but in fact it requires very rich experience and technical knowledge. While the material cannot be controlled by high pressure, the environmental temperature, environmental humidity, mold type, material specification, material Factors such as pretreatment quality will directly affect the final quality of rotomolding products. Put the powdered plastic into the hollow mold. Close the mold and rotate along the two axes. Heating the mold during the rotation process to melt the powder material. After all the materials are melted, cool the mold.After the product has solidified, open the mold and take out the product.
In the production process, it is difficult to completely fill the mold, and there are certain technical requirements. After the curing stage is over, different products have different stiffness, which has an impact on product performance. For products with high dimensional accuracy requirements (especially for multi-cavity molds), the process is somewhat short. The flash of the final product is thicker, and the workload of removing the flash is large. The shortcomings of compression molding are that the mold manufacturing is complicated, the investment is relatively large, and coupled with the limitation of the press, it is most suitable for mass production of small and medium composite materials.
