What is the injection molding process for pet products?

The pet product injection molding process is a complex and delicate process that involves several key steps to ensure the quality and performance of the final product.

The following are the detailed steps of the injection molding process for pet products, mainly including the following 6 aspects:

(1) Mold design
This is the starting point of the entire injection molding process, and the quality of the mold design directly affects the shape, size and structure of the subsequent products. Designers need to carry out mold design according to the specific requirements of pet products, combined with market demand and cost control and other factors.

(2) Mold manufacturing
Mold manufacturing is a key link in the injection molding process, requiring the use of high-precision processing equipment and technology to ensure the accuracy and durability of the mold. After the mold manufacturing is completed, strict inspection and debugging are required to ensure that it meets the design requirements.

(3) Injection molding stage
First, the plastic raw material is heated to a molten state and then injected into the mold by high pressure. During the injection process, parameters such as injection speed, pressure and temperature need to be precisely controlled to ensure that the plastic raw material can be evenly filled with the mold. After the injection is completed, the mold needs to be held under pressure and cooled for a period of time to ensure the density and shape stability of the product.

(4) Open mold operation
When opening the mold, it is necessary to ensure smooth and rapid action to avoid damage to the product. Then, take out the product and carry out the necessary post-processing, such as trimming the raw edge, polishing the surface, etc.

(5) Inspection and packaging
Strict inspection is carried out on each product to ensure that it meets quality standards. Qualified products are packaged for transportation and storage.

(6) Finished products are stored
Put the packaged pet supplies into the warehouse for sale or delivery.

In the entire injection molding process, it is also necessary to pay attention to safe production and environmental protection. Workers need to wear appropriate protective equipment to ensure safe operation; At the same time, waste and wastewater should be treated rationally to reduce environmental pollution.

In general, pet products injection molding process is a rigorous, fine process, which involves the precise control of multiple links and parameters. By continuously optimizing the process flow and improving the technical level, product quality and production efficiency can be further improved to meet the market demand.
