It is understood that the processing stage of two-color mold parts is an important stage to ensure the accuracy of the mold, which mainly includes four steps, namely, mechanical processing, special processing, surface processing and heat treatment. The following Shandong mold will be analyzed for you in detail:
1. Machining mainly uses cutting machine tools to process metal materials.
As we all know, the mold is almost assembled by metal parts. In order to get the parts that meet the requirements of the drawings, the most important means is to use machining. Therefore, machining is one of the most workload.
2. Special processing, mold structure is relatively special.
Because the plastic product is a three-dimensional part, it is formed by the combination of male and female molds in the cavity. This kind of cavity with curved surface is difficult to deal with in general machining, even if it is barely machined, its quality is difficult to guarantee. Therefore, special machining, such as EDM, is needed. Electroforming processing, etc. These special processing methods have become indispensable in mold processing.
3. Surface processing.
Generally, the surface of plastic products is required to be high, and the surface of plastic parts is required to be glossy, round and beautiful, which requires the corresponding cavity surface to be very smooth and round. Because the cavity is generally curved surface, it is difficult to guarantee the quality with normal machining, which requires special surface processing of the mold, mainly including grinding and polishing, electrochemical polishing, ultrasonic polishing, extrusion Grinding and polishing, shot peening, etc.
4. Heat treatment.
In the production of injection mold, all the important parts need to be heat treated, and some parts need to be treated many times. Because heat treatment is the main method to change the properties of metal materials. Due to the fact that the mold is usually produced in a single piece and the manufacturing cost is not cheap, people always hope that it can be used more often. Therefore, the mold is required to be durable, and heat treatment can change its internal structure and performance without changing the shape and size of the part, which is an important method to ensure the internal quality of the part.
The above is the introduction of the processing process of the two-color mold parts. This article is provided by Shandong mold friendship. If you want to know more mold processing skills, please consult the website http://www.436695.tw 。
