Hardware mold manufacturing can design corresponding molds according to different product characteristics and needs. Different mold structures and functions are also different, and the products produced are also different. Today, small make up with you specifically about the characteristics of metal mold manufacturing and machining accuracy and error related knowledge.

The number of parts or engineering content completed per unit time is several times higher than the general processing method, or even hundreds of times. In addition, the metal mold manufacturing process can be used in the mold centralized application of multi-piece, multi-process content combination processing, to further improve production efficiency.
2, product quality is stable, good exchange, the use of metal stamping products, the impact of product quality changes in the factors less, low risk. Some factors can take appropriate measures to correct, product quality management in the ideal range to ensure the stability of quality, can effectively ensure its exchangeability. Good exchangeability is the basic guarantee of mass production of assembly line. At the same time, it is also conducive to the maintenance and replacement of products.
3. High material utilization rate can improve the utilization rate of materials and reduce the material cost of products through various superposition methods such as cross, tilt, multi-row, mixing, superposition, and even superposition without waste.
4. The material does not need to be heated. Usually, the metal mold manufacturing process does not need to heat the material. This can not only save energy, reduce heating equipment and site occupation, but also prevent the surface oxidation and deformation of the product caused by the heating furnace from being unstable in shape and size. In addition, adverse effects of temperature rise on the mold can be prevented.
5. The mechanical properties of stamping are improved. Affected by the phenomenon of metal stamping hardening, the stamping surface is dense, the hardness and wear resistance are increased, and the stamping strength and rigidity are also improved.
Hardware mold manufacturing processing accuracy and error are terms for evaluating surface geometric parameters. The machining accuracy is measured by the tolerance level, and the smaller the level value, the higher the accuracy. The processing error is expressed in numbers, and the larger the number, the greater the error. The machining accuracy is high, and the machining error is small, and vice versa. The actual parameters obtained by the processing method are absolutely inaccurate. In the function of the part, as long as the machining error is within the tolerance range required by the part drawing, it is considered to ensure the machining accuracy.
Position accuracy: Indicates the difference in the actual position accuracy of the part between the machined surfaces. Controlled by the position tolerance, the position tolerance of each item is also divided into 12 accuracy levels.
The relationship between the dimensional accuracy, shape accuracy and position accuracy of mold accessories: usually when designing machine parts and specifying the machining accuracy of parts, attention should be paid to controlling the shape error within the position tolerance, and the position error should be less than the dimensional tolerance.
