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 needs of the product.
2. Manufacturing molds
The manufacturing of molds is an important part of injection molding. The mold needs to have high manufacturing accuracy, long service life, and adapt to different processing conditions. Mold manufacturing requires the use of professional mechanical equipment for cutting, polishing, and debugging processes based on design drawings. During 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
When the raw materials are melted and mixed, they are injected into the mold. The injection molding opportunity 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. Demolding and post-processing
After cooling and curing, the product needs to be removed from the mold. When taking out, it is necessary to consider the shape and structure of the product to ensure that it can be completely taken out. 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 finish, 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 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, precise measuring equipment and testing instruments need to be used, and the detection results need to be analyzed and judged.
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.
