Plastic molding wholesale provider 2024: 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. Read many more info on China plastic molding company.

The shrinkage of the product is small and the repeatability is good. A mold with a large number of cavities can be placed on a given template, and the productivity is high. It can be adapted to automatic feeding and automatic removal of products. High production efficiency, easy to realize specialized and automated production. The product has high dimensional accuracy and good repeatability. The surface is smooth and clean without secondary modification. Products with complex structures can be formed at one time. Mass production, relatively low price.
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.
We can come into contact with toothbrushes every day. Its base material is injection molding made of steel plastic, which is very hard and tough. The rubber handle on the handle can effectively help us to prevent slippage, and can improve the color matching and aesthetic appearance. The product is derived from the overmolding process and is suitable for mass production. Improve product surface friction; Can achieve a more ergonomic design; Improve product electrical insulation; Create products with better sealing; Effectively isolate vibration and sound transmission. Improve color matching options and improve aesthetics. Reduce the use of harmful adhesives and other consumables. Increase manufacturing efficiency, suitable for mass production. The product structure is not restricted, and the adaptability is high. Find additional details at china-plasticparts.com.
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.
