Four indicators of custom mold determine the price

The accuracy of the mold includes dimensional accuracy, shape accuracy, position accuracy and surface roughness. The accuracy of the mold is mainly reflected in the accuracy of the mold parts and the matching accuracy. The precision of the working part of the mold is higher than the precision of the product parts. For example, the precision of the blanking edge size is higher than that of the product parts. The numerical size and uniformity of the blanking punch and die blanking gap are also the main precision. one of the parameters.

The accuracy usually measured is the accuracy in non-working state (such as blanking gap), that is, static accuracy. In the working state, under the influence of working conditions, the static accuracy and the change become dynamic accuracy, and the dynamic accuracy is the real meaningful data.

Generally, the accuracy of the mold should be coordinated with the accuracy of the product, and at the same time, it is also restricted by the mold processing technology. Replacement production will also produce will also become a reality.

It is very important for high-speed stamping dies, large-scale stamping and forming dies, precision plastic molds and large-scale plastic molds, which not only require high precision, but also require good rigidity.

The working load of this type of mold is relatively large. When a large elastic deformation occurs, it will not only affect the dynamic accuracy of the mold, but also whether the mold can work normally. Therefore, in the mold design, while meeting the strength requirements, it should be Ensure the rigidity of the mold, and at the same time avoid additional deformation due to improper processing during manufacturing.
