Overmolding

Overmolding processing refers to the process of processing metallic or non-metallic materials using specific processes and equipment to produce a mold that meets the design requirements. Injection overmolding processing plays a vital role in industrial production; it is the basis for the production of parts and products, widely used in automobile manufacturing, electronic equipment, home appliances, plastic products, and other industries.

Overmolding Process

1.Overmolding design and planning:

The first step of overmolding processing is to design and plan the mold according to the design requirements of the product. Designers determine the structure, parts, and materials of the mold according to the size, shape, and functional requirements of the product.

2.Overmolding material preparation:

According to the design requirements, select appropriate metal or non-metal materials and carry out material preparation. This includes the steps of material selection, cutting, and adjusting material size. For example: P20, 718, NAK80, S316H

3.Processing Overmolding:

According to the design drawings of the overmolding, process each part. This includes CNC milling, turning, drilling, wire cutting, grinding, and other processes. The machining process needs to strictly control the size and surface accuracy to ensure the quality and accuracy of the parts.

4.Assembly and commissioning:

The processed parts are assembled to form a complete overmolding structure. In the assembly process, we need to ensure the matching precision and sealing between the parts, as well as the reliability and stability of the mold. After the assembly is completed, debugging and testing of the injection overmolding is carried out to ensure its normal operation.

5. Surface treatment:

Necessary treatment is carried out on the surface of the overmolding to improve its wear resistance, corrosion resistance, and reduce the coefficient of friction. Common surface treatment methods include electroplating, spraying, polishing, and so on.

6. Trial and repair overmolding:

After completing the production of the overmolding, carry out the work of trial and repair overmolding. Through the trial overmolding, the design and processing quality of the overmolding can be verified to ensure that the overmolding can meet the production requirements of the product. If problems are found, overmolding repair is required, including adjusting the size, shape, and fit of the overmolding.

7. Maintenance and repair:

Overmolding will be subject to wear and tear and damage in the process of use, need to carry out maintenance and repair work to extend the service life of the mold and maintain processing accuracy. Maintenance work includes cleaning, lubrication, and replacement of damaged parts.

Overmolding processing is a complex process that requires the collaboration of designers, processing technicians, and debuggers. Through accurate design and high-quality processing, overmolding with stable performance and accurate dimensions can be produced, providing a reliable guarantee for the production of products. At the same time, overmolding processing is also a process of continuous improvement and innovation. With the development of science and technology and the changing needs of the market, overmolding processing technology is also constantly developing and progressing.
