Injection molding operation process and precautions

Injection molding is a production process in which plastic raw materials are heated to a molten state, injected into a mold, and cooled to obtain the desired shape of the product. This process has the advantages of high efficiency, low cost and suitable for large-scale production, and is widely used in various industries.

Operation process:

1. Ingredients: According to the production requirements, different types of plastic particles are added to the injection molding machine.

2. Heating: the plastic particles are heated to a molten state, which is generally completed by the heating cylinder of the injection molding machine.

3. Plasticizing: the molten plastic is injected into the mold through the nozzle of the injection molding machine, and the temperature and fluidity of the plastic need to be ensured at this time.

4. Pressure preservation: After the plastic injection mold, it is necessary to maintain a certain pressure to ensure the integrity and accuracy of the product after molding.

5. Cooling: After holding the pressure for a certain time, open the mold, take out the product, and cool it.

6. Packaging: Pack the cooled product for subsequent use.

Note:

1. Temperature: During the operation, it is necessary to ensure that the temperature of the plastic is within the appropriate range, too high or too low temperature will affect the quality and accuracy of the product.

2. Pressure: In the injection process, to maintain the appropriate pressure, too much or too little pressure will affect the molding effect of the product.

3. Time: In the process of pressure holding and cooling, it is necessary to master the time, too long or too short will affect the quality and efficiency of the product.

4. Materials: Different plastic materials have different processing characteristics, and appropriate materials should be selected according to production requirements.

5. Safety: During the operation, pay attention to safety and avoid contact with high-temperature equipment and materials to prevent accidents.


Injection molding is an important production process, to master the operation process and precautions, in order to produce high-quality products.
