According to statistics, in the traditional mold manufacturing, the actual processing time of the machine tool is only about 50%, and the other half of the time is spent on clamping, workpiece and tool replacement. The mold automatic processing can give full play to the processing efficiency of the machine tool, and make the processing time rise to 90%. Machining accuracy is the actual size, shape and position of the machined part surface, which is consistent with the ideal geometric parameters required by the drawing. Machining accuracy is measured by tolerance grade, the smaller the grade value is, the higher the accuracy is; machining error is expressed by numerical value, the larger the numerical value is, the larger the error is. The level of automobile parts processing and mold manufacturing has become an important symbol to measure the level of a country's manufacturing industry, and also one of the important guarantees for a country's industrial products to maintain international competitiveness. In recent years, the market scale of China's mold industry has been expanding, and the main business income has increased rapidly, from 23.064 billion yuan at the end of 2004 to 247.419 billion yuan at the end of 2014.
With the rapid progress of technology, people may ignore the endless variety of new cutting tools in the market. Cemented carbide tool manufacturers for auto parts processing constantly improve the tool geometry design and constantly update their tool technology. Mold manufacturers can choose a variety of different tools for their mold processing. Nowadays, in the mold processing industry, it is very common for manufacturers to use aluminum alloy material instead of mold steel to make injection mold. Compared with steel molds, aluminum molds are easier to manufacture, operate and use, and cost recovery time is shorter. In most cases, the quality of plastic products produced with aluminum molds is better.
