The characteristics of mold processing are simple and important!

The characteristics of mold processing are simple and important!

1. High accuracy

The mold should not only have high machining accuracy, but also have good machining quality. The general tolerance range should be controlled at the micrometer level. Only high-precision molds can ensure that the product can achieve a certain degree of accuracy, ensure the qualification rate of the product, and extend the service life of the mold. Long service life, molds are a relatively expensive process equipment, and their processing costs account for approximately 10% to 30% of the cost. Therefore, requiring molds to have a longer service life is more meaningful.

2. Short manufacturing cycle

This is mainly to meet production requirements and market competitiveness of the product. Low cost. The cost of molds is related to the complexity of the mold structure, mold materials, manufacturing accuracy requirements, and processing methods. Therefore, it is necessary to design and develop processing techniques reasonably, select appropriate processing equipment, and ensure lower processing costs.

3. Complex mold shape

The working part of a mold is generally a two-dimensional or three-dimensional complex surface, rather than a simple plane. For example, the inner cavity of automotive panel molds is mostly composed of curved surfaces. The material used has a high hardness, and generally the mold is made of quenched tool steel or hard alloy, which is difficult to process using traditional processing methods. At present, in the process of mold manufacturing, ordinary mechanical processing and electric discharge machining are mainly used. In order to shorten the manufacturing cycle and reduce costs, advanced cutting techniques must be widely used to process molds. High speed cutting technology, as an advanced manufacturing technology, has emerged to meet the requirements and characteristics of mold processing.
