The working principle of L-shaped plastic mould is as follows:

1. Feeding: plastic raw materials are added to the barrel of the injection molding machine.

2. Heating and melting: the plastic is melted by heating.

3. Injection molding filling: under the pressure, molten plastic is injected into the mold cavity.

4. Cooling and setting: the plastic is cooled and set quickly by using the cooling system of the mold.

5. demoulding and taking parts: open the mold and take out the molded L-shaped plastic products.

In this process, the design and manufacture of the mold is very important:

1. Cavity and core: determine the shape and size of L-shape.

2. Gate and runner: optimize the flow of plastic melt.

3. Cooling system: control the cooling speed to ensure the product quality.

Its advantages include:

1. Efficient mass production.

2. Complex shapes can be manufactured.

3. The cost is relatively low.

In order to ensure the quality, attention should be paid to:

1. Choose suitable plastic raw materials.

2. Precise control of process parameters.

3. Maintain the mold regularly.
