1. Design mold

Injection molding requires the use of molds, so the first step is to design molds. The design of the mold needs to consider factors such as the shape, size, material, and production quantity of the product. When designing molds, it is necessary to choose appropriate mold materials, such as steel or aluminum, based on the characteristics and requirements of the product.

2. Manufacturing molds

The manufacturing of molds is an important part of injection molding. The mold needs to have the characteristics of high manufacturing accuracy, long service life, and adaptability to different processing conditions. Mold manufacturing requires the use of professional mechanical equipment for cutting, polishing, and debugging processes based on design drawings. In the manufacturing process, it is necessary to ensure that the accuracy and dimensions of the mold meet the requirements to ensure the quality and consistency of the product.

3. Prepare raw materials

The raw materials used in injection molding are granular and need to be added to the injection molding machine for melting and mixing. The selection of raw materials needs to be based on the needs and requirements of the product, such as the type, hardness, color, etc. of plastic. During the preparation process of raw materials, precise measuring equipment needs to be used for raw material proportioning to ensure the quality and consistency of the raw materials.

4. Injection molding

After the raw materials are melted and mixed, they will be injected into the mold. The injection molding machine injects molten plastic into the mold through pressure and forms the desired product shape in the mold. Injection molding requires controlling parameters such as injection time, injection temperature, and injection pressure to ensure product quality and consistency.

5. Cooling and Curing

After injection molding, the product needs to be cooled and cured in the mold for a period of time. The length of cooling time depends on the size and shape of the product. During the cooling process inside the mold, the plastic will gradually solidify and solidify, forming the desired product shape.

6. Demoulding and post-processing

After cooling and curing are completed, the product needs to be removed from the mold. When removing, it is necessary to consider the shape and structure of the product to ensure that it can be completely removed. After removal, the product needs to undergo subsequent processing and processing, such as trimming, polishing, etc. These processes have a significant impact on the surface smoothness, accuracy, and appearance quality of the product.

7. Inspection and Testing

The products produced need to undergo inspection and testing to ensure the quality and consistency of the injection molded products. The content of inspection and testing includes the size, shape, appearance quality, mechanical properties, and other aspects of the product. During the inspection and testing process, it is necessary to use precision measuring equipment and testing instruments, and analyze and judge the test results.

8. Packaging and Shipping

Products that pass inspection and testing can be packaged and shipped. Packaging needs to consider factors such as product size, quantity, and transportation method to ensure that the product is not damaged during transportation. Before shipment, it is necessary to conduct a final inspection and confirmation of the product, and ensure that it meets the customer's requirements and needs.
