The focus of precision mold processing must be on precision. Compared to ordinary molds, precision molds have very high requirements for dimensional tolerances, typically within+/-0.001. During the manufacturing process of precision molds, it is necessary to strive for excellence in their raw materials, design, processing, accuracy, size, and other aspects. The processing process must be a high-precision processing and molding process. For example, the production and processing method commonly used for injection molding is wire cutting, while precision molds are likely to use slow threading.

The main specifications of many precision molds do not allow gradients, but in mold production, it is generally flexible to use tolerance levels plus minor gradients, such as transmission gear mounting studs. When designing drawings for precision molds, it is necessary to consider the operability and controllability of processing to ensure the smooth progress of processing.

Main characteristics of precision mold processing:

1. Complex shapes and surfaces: Some commodities, such as vehicle covers, airport parts, small toys, and electrical products, have a surface layer composed of different bevels, and some of them must be solved using mathematical calculations.

2. High machining accuracy requirements: A mold is generally composed of a concave mold, a mold base, and a mold embryo. Some may also be multiple splicing control modules, and the splicing in the middle of the control module is required to have a high machining accuracy. The specification accuracy of high-precision molds usually reaches μ Level m.

3. There are many processes for precision mold processing: various processes such as milling, boring, drilling, reaming, and tapping external threads are always used in mold production and processing.

4. Repeated construction and production: The use of molds has a service life. When the application of a mold exceeds its service life, it is necessary to replace it with a new mold, so the production and manufacturing of the mold often involves duplication.

5. Large quantity and small quantity: The production and manufacturing of molds is not mass production, and precision mold manufacturing usually only produces one mold in many cases.

6. Copying production and processing: Sometimes there are neither drawings nor data information in mold production and manufacturing, and it is necessary to carry out copying production and processing based on entities.
