What are the characteristics of metal powder mold?

Apr 28, 2019

Metal powder molds must not only have high processing precision, but also have good processing quality. In general, the tolerance range should be controlled on the order of microns. Only the high-precision metal powder mold can guarantee the product to achieve a certain precision and ensure the qualified rate of the product, so that it is possible to extend the use of the mold.


The metal powder mold processing cycle is short, which is mainly to meet the production requirements and market competitiveness of the product. The cost is low, and the cost of the metal powder mold is related to the complexity of the mold structure, the mold material, the manufacturing precision requirements, and the processing method. Therefore, it is necessary to rationally design and formulate the processing technology and select appropriate processing equipment to ensure low processing costs.


Metal powder molds are complex in shape, and the working part of the mold is generally a two-dimensional or three-dimensional complex surface rather than a simple plane. For example, automotive cover moulds, the interior of which is mostly composed of curved surfaces. At present, in the processing and manufacturing process of metal powder molds, mainly machining and EDM are the main processes. To shorten the manufacturing cycle and reduce costs, advanced cutting technology must be widely used to process molds. The emergence of high-speed cutting technology as an advanced manufacturing technology meets the requirements and characteristics of mold processing.
