The Production Process And Precautions Of Custom Refrigerator Injection Molds

Manufacturing refrigerator injection molds

The manufacturing of refrigerator injection molds requires processes such as cutting steel billets, cooling steel billets, milling steel billets, processing templates, and grinding templates. First, cut the steel billets into the required size and shape, then assemble the templates, use a milling machine to process the convex and concave shapes on the template surface, and use electric spark machining to make a more refined internal space. Finally, polish the template and design an injection-molded tetrahedron. The above processes need to be carried out strictly in accordance with the process flow to ensure the stability and service life of the mold.

Test the injection mold

After the refrigerator injection mold is completed, it needs to be tested to ensure the performance and reliability of the injection mold. The test methods include comprehensive inspection, injection molding front and back, injection molding adjacent edges, cooling water and high-pressure airway test items to test the service life of the mold and the quality of injection molding production.

Grinding injection mold

After the refrigerator injection mold has been used for a period of time, it needs to be ground to extend the service life of the mold. During the grinding process, it is necessary to select the appropriate grinding method according to the wear of the mold, repair the pits and wear on the mold surface, and adjust the size. After grinding, the quality of the mold must be tested to ensure that the mold can be used normally after grinding.

Precautions

When making refrigerator injection molds, the following points should be noted:

1. The quality of the steel must be guaranteed, and the inside of the mold should be treated with high temperature to ensure the service life.
2. The wall thickness, internal and external shapes of the mold should be consistent with the design of the refrigerator injection molded product to obtain the ideal injection molded product.
3. The mold should have the ability to adjust the size.
4. Avoid collision, fall and other damage during mold transportation and storage.
5. Regular maintenance and maintenance should be performed during mold use.
6. During the injection molding process, the injection molding and operation specifications must be strictly followed.
