Premium plastic mold manufacturer factory: 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.

If your product quantity is relatively small, we can provide fast mold service, which is a fast turnaround and low price mode, but the disadvantage is that the quality of the mold is not good, and it is unable to undertake too many product manufacturing tasks. From the design of the mold to the final test of the mold, all the processes are carried out in our internal injection workshop and the mold workshop. We reserve a lot of material warehouses for manufacturing high-quality molds, which are in line with most plastic products, there are many spare parts in reserve, we can call for use at any time. The injection molding workshop is next to the mold workshop. After the mold is manufactured, the injection molding equipment can be installed and tested within a few hours. This is the key to rapid response.
Blow molding is a plastic molding process for rapid production of hollow structure products. Many products in life will choose injection blow molding for packaging, such as water bottles, oil drums, children’s toys, etc. This is an economical and efficient plastic molding process. It is also suitable for mass production of plastic products. Mulan Group has been engaged in the production of blow molding parts for more than 15 years. It has two large blow molding manufacturing bases that produce small injection blow molding parts, such as medical test tubes, cosmetic bottles, drinking water bottles, etc. And large-scale extrusion blow molding products, such as insulation barrels, oil drums, car water tanks, tool boxes, etc.
Rotational molding can achieve very uniform wall thickness, and the corners will be thickened, which greatly enhances the strength and integrity of the product. Unlike blow molding, the corners will be pulled thin by pressure and cracked. , Affect the intensity. Rotational molding has also become rotomoulding. Rotational molding is a method in which thermoplastic plastics are rotated to form hollow plastic parts. The plastic raw material powder is added to the mold, and the mold is continuously rotated along two axes while heating. Under the action of gravity and thermal energy, the material presents a hollow plastic part with uniform wall thickness and complex structure.
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.
Mainly used as structural parts, connectors, protective parts and electrical insulation parts. It is widely used in industry, agriculture, transportation, electrical, chemical, construction, machinery and other fields. Because of the reliable quality of molded products, they have also been used in weapons, aircraft, missiles, and satellites. The molding cycle in the entire production process is long, the efficiency is low, and the staff has a large physical consumption. It is not suitable for molding complex products with depressions, side slopes or small holes.
