Injection molding
Also known as injection molding, it is a molding method of injection molding. The advantages of injection molding method are fast production speed, high efficiency, operation can be automated, variety of designs colors, shapes can be varied simple to complex, sizes can be varied large to small, products can be easily updated can be made into parts with complex shapes, injection molding It is suitable for forming processing fields such as mass production products with complex shapes.
At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, cooled solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes is one of the important processing methods.
Rotomolding
Also known as rotational molding, rotational molding, rotational molding, rotational casting, rotational molding, etc. Rotational molding process is to first add plastic raw materials into the mold, then the mold is continuously rotated along two vertical axes heated, so that the plastic raw materials in the mold gradually uniformly coat, melt adhere to the mold under the action of gravity thermal energy. The whole surface of the cavity is formed into the required shape, then cooled shaped, demolded, finally the product is obtained.
