Plastic molding manufacturer and supplier in China: Stretch blow molding is the process method of billet, stretch and blow molding in a machine. Billet is a semi-finished product in the production process. After cooling, cold billet is reheated to stretch and blow molding. After extrusion molding, directional tensile blow molding, maintain a certain tensile speed, orientation before blowing, after stretching, transparency, impact strength, hardness and rigidity, surface gloss and barrier properties have been higher. The production process of stretch blow molding is to control the temperature of the billet below the melting point under the principle of bidirectional bigeneration to improve the strength of the product.

Only high-quality molds can produce high-quality products. Many times we will receive feedback from customers, “I don’t agree with the price of your injection mold, why is it so high?”. Such problems are mainly concentrated in non-professional mold technicians, who only calculate the average cost of the mold on the product, without real research and exploration, how important a high-quality mold is to the quality of the product and the progress of the overall project. We have many methods for low-cost molds, but we have lost 100% of the assurance of the quality of your products. The cost of the mold depends on the size, structure, material, product quantity and other special requirements of the part. For example: if you need 1,000 injection parts, then we will actively recommend that you choose a low-cost single-cavity mold, which can meet the quality and deliver the product on time. The most important thing is low-cost investment.
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.

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 more details at china-plasticparts.com.
Rotomolding products & mold design: We provide customers with professional rotomolding design technical support services, mainly focusing on the design of rotomolding molds. We use our rich experience to reduce quality risks in the design and ensure the high quality of products as you expect , And reduce the cost of mold modification due to design errors. In-house Mold Manufacturing: We have a powerful rotational molding mold manufacturing center, three 5-meter-long CNC machining centers, which can accurately engrave the details of the mold. Usually we will use high-quality aluminum alloy or cast aluminum to make rotomolding molds. High-quality mold manufacturing ensures that you can receive the highest quality products in the shortest time and have economic benefits. And we can add custom textures, logos, batch numbers and other copywriting on the surface of the mold.
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.
