How to process maple, special, surface and heat treatment of parts?
In order to ensure the accuracy of the mold, parts must be processed, mainly including: mechanical processing, special processing, surface processing and heat treatment.Machining is mainly to use the cutting machine tool to process metal materials.
The machined dies are almost assembled from metal parts.In order to get the parts that meet the requirements of the drawings, most of them are machined.Therefore, machining is one of the most laborious parts.
The special processing mold structure is quite special, and there are many plastic products of solid parts, which are formed in the cavity of convex and concave mould combination.This kind of curved cavity is very difficult to be machined by general machinery. Even if it is machined reluctantly, its quality is not guaranteed.Therefore, it is necessary to adopt special processing, such as electric spark processing, electroforming molding and so on.These special processing has become an indispensable processing method in mold processing.
(3) the surface processing general requirements for the surface of the plastic products is higher, the plastic parts surface luster, beautiful round, which requires the corresponding to the cavity surface is very smooth and round, due to the cavity is usually curved surface, with usually hard to ensure machining quality, generally need to specialized mold surface machining, grinding and polishing, electrochemical polishing, ultrasonic polishing, squeezing grinding polishing, shot peening, polishing, etc.
In the production of injection moulds, all important parts are heat treated, and some parts are processed many times.Because heat treatment is the main way to change the properties of metal materials.Mold is commonly piece production, companies want to reduce the mold cost and demand mould is durable, and the heat treatment can without changing the shape and dimension change under the condition of the internal organization and performance, is an important method to ensure the quality of inner parts.
