Plastic trays are widely used in household items, and they are also very convenient to use with a wide range of applications. However, people may not be very familiar with their production process, so follow the plastic tray manufacturer to learn about its production process. Firstly, there should be an injection molding and blow molding machine, and then the corresponding molds should be processed or purchased.

1、 Injection molding process

Excellent molds can produce products with complex shapes, accurate dimensions, and embedded parts in one go, making it convenient to mass produce products with identical dimensions, shapes, and functions. Injection molding has good production functions, short molding cycles, and can also implement automated or semi automated operations, with high production efficiency and skill economic indicators.

2、 Extrusion molding process

Suitable for the molding of some thermosetting plastics and reinforced plastics with good fluidity, it is an early used, widely used, and highly applicable molding method in the plastic processing industry, and is also produced based on molds. The plastic products processed by extrusion molding are mainly continuous profile products.

3、 Compression molding process

Used for the production of thermosetting plastic products, it is divided into compression molding and lamination molding. Compression molding is the use of upper and lower molds to press materials, which undergo chemical reactions to solidify and form. Laminated molding is the process of laminating resin impregnated sheet materials to the desired thickness and placing them in a laminating machine to bond and cure them into layered products at specific temperatures and pressures.

4、 Blow molding process

In the production of hollow plastic products such as bottles, packaging boxes, fuel tanks, toys, etc. Some of them are also used in the production of furniture parts.

5、 Casting and molding process

Pour the liquid resin mixture with curing agent and other additives into the molding mold, and gradually cure it under specific conditions to become a product with a specific shape. Suitable for plastics with high fluidity and shortening properties.

The above five are the production processes of plastic discs. Simply put, one is injection molding and the other is blow molding. Specifically, injection molding involves placing the material into an injection molding machine, melting it, and injecting it into a mold for cooling and forming. Blow molding involves first melting the material into a tube blank, which is then placed into the mold and molded using compressed air.
