The rushing process for improving the quality and size accuracy of the customized shear surface of the car hardware is called precision. The secondary processing of ordinary feeding parts is usually referred to as precision processing, including repair and squeezing.

The precision punching process of precision stamping parts, if it is promoted and applied to factories with simple shapes, only partial stubborn, small size, small output, and no special fine -free equipment, it can also achieve good technical and economic benefits and have good development prospects. The application industry of fine -cut technology includes cars, motorcycles, computers, video recorders, communication equipment, aircraft manufacturing, home appliances, office machinery, optical components, air conditioners, compressors, etc.

Strong pressure plate essence (FB), which has a strong pressure plate with different structures, used for the maintenance of the blank, and the reverse top upgrade 

The harmonious tailor, including the V -shaped gear pumping technology maintained in the production of strong rough materials, and the less use of a sawtoral pyrophology method, tapered pressure plates and convex stamping plates.

Hedge mold essence — using the principle of plane cutting, and using a pair of public models and mother models corresponding to the upper and lower cuts at an angle of angle. It is a fine -rushing technology invented by the Japanese in 1968 and promoted production in Japan. It is also used in China, but it is not popular.
