How to control automotive parts quality during injection molding?

1. Molding Cycle

The time required to complete an injection molding process is called the molding cycle, also known as the molding cycle, molding cycle directly affects labor productivity and equipment utilization.

Therefore, in the production process, the quality of the premise should be ensured to minimize the relevant time in the molding cycle. In the entire molding cycle, the injection time and cooling time are the most important, they have a decisive impact on the quality of products.

2. The pressure control

Pressure in the injection molding process includes both plasticizing pressure and injection pressure and directly affects the plasticizing and product quality of the plastic.

3. Temperature Control

The temperatures that need to be controlled during injection molding are barrel temperature, nozzle temperature, and mold temperature. The first two temperatures affect the plasticizing and flowing of the plastic, while the latter temperature mainly affects the flowing and cooling of the plastic.

How to maintain the surface of automotive molds?

We should pay attention to the surface maintenance of automotive molds, which directly affects the surface quality of the products and focuses on preventing rusting, therefore, it is very important to choose a suitable, high quality, and professional anti-rust oil.

When the mold has finished its production, different methods should be used to carefully remove the remaining injection molding according to the different injection molding, and copper rods, copper wires, and professional mold cleaner can be used to remove the remaining injection molding and other deposits in the mold, and then air dry.

It is forbidden to use iron wire, steel bar, or other hard objects to remove the residue to avoid scratching the surface. If there are rust spots caused by corrosive injection molding, grind and polish them with a grinding machine and spray with professional anti-rust oil, then store the mold in a dry, cool, and dust-free place.
