What is the production process of precision mold and its key technology?

Precision mold is a kind of mold with high precision, large size and complex shape, which is widely used in the production and manufacturing of automobile, electronics, aerospace, medical equipment and other fields. The production process of precision mold and its key technologies are important content in the mold industry, and the following is a detailed introduction.

First, the production process of precision mold

1. Design stage: In the mold design stage, it is necessary to carry out relevant design and analysis according to customer needs, and determine the model, size, shape, material and related parameters of the mold.

2. Processing preparation: Processing preparation usually includes mold material selection, parts processing, mold surface treatment, mold assembly, etc.

3. Processing and manufacturing: The core of precision mold manufacturing is processing and manufacturing, and its process includes drilling, milling, turning, electric discharge machining, wire cutting, grinding and a series of processes.

4. Mold debugging: After mold manufacturing is completed, mold debugging needs to be carried out, which includes testing and checking the processing accuracy and production efficiency of the mold to ensure that the mold fully meets customer requirements.

5. Delivery and after-sales service: Later, the precision mold will be sent to the customer site, and provide related after-sales service.

2. Key technologies

1. Material selection: Precision molds are usually large, so the stability and reliability of materials are required. In terms of material selection, some high-strength, wear-resistant, high-hardness carbon steel, alloy steel, tungsten steel and other materials are commonly used.

2. Processing technology: Modern processing technology plays an important role in the mold manufacturing process. Machining technology, the application of new cutting tools and CAE (computer aided engineering) technology can effectively enhance the processing efficiency and improve the processing accuracy.

3. Debugging technology: Due to the high processing accuracy and production efficiency of precision molds, it is necessary to use high-precision test tools to provide effective data for analysis and processing during mold debugging to ensure that the molds meet customer requirements.

4. Surface treatment technology: precision mold surface treatment technology is very key, it can protect the hardness, toughness, wear resistance, corrosion resistance of the mold, color and texture characteristics can also be effectively protected. Some surface treatment technologies, such as electroplating, electroless plating, sulfur oxidation and other technologies are widely used in this respect.

5. Mold design: Precision mold design should pay attention to reduce the number of parts, improve the production efficiency of the mold, simplify the mold operation and maintenance, and reduce the size and weight of the precision mold as much as possible.

The above is my summary of the precision mold production process and its key technologies. Precision mold is a high-tech, high-quality product, in the manufacturing process need to pay close attention to the details of each link, and finally produce a qualified mold, to ensure the stability and reliability of mold quality, to provide high-quality products and services for the manufacturing industry in various industries.
