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.
As an injection mold manufacturer, Mulan Group has been engaged in plastic molding molds for more than 25 years. We have a professional in-house mold manufacturing factory, located in Shanghai, China, a high-quality mold manufacturing base, equipped with a team of engineers with rich manufacturing experience and professional knowledge. Rely on digital programming software and equipment to customize precision injection mold services after the part design is completed. Allow the material to fill the mold cavity without obstacles to ensure that the product will not have defects. For some appearance parts, a smooth surface is an important factor in obtaining market value. We will use very small pinhole feeds. There are no traces on the surface of the product, and it is hidden on the surface of the product installation part.
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.
Rotomolding molds are usually made of cast aluminum or steel plates without the aid of high pressure, so the mold process is relatively simple, the cost is low, and small batch production has economic advantages and is suitable for early investment in product development. Rotomolding relies on the material to adhere to the inner wall of the mold, which has very low restrictions on the shape of the product. It can be achieved smoothly through reasonable design of the mold details. And you can easily create functions such as reinforced ribs, custom textures, and in-mold inlays.
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. Discover more information on china-plasticparts.com.
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.
