Metal stamping parts are parts that can be processed by stamping, bending, stretching and other means. A general definition is the parts with constant thickness in the process of processing. Metal stamping is very important in industrial production. It is widely used in electronics, auto parts, mechanical parts, etc., but what kind of metal stamping parts are qualified products? How does the metal stamping parts factory produce qualified products? Now the automobile stamping parts factory will explain to you how to identify the metal stamping parts process is qualified.

Carefully observe whether the appearance is rough, and then use the hand slide switch test several times to see whether it is sensitive and whether there is abnormal noise. Do not compare with the furniture hardware, but need to compare with the similar products. It depends on the materials. The materials used are relatively good. The manufacturer should have a long business history and high reputation as far as possible. (jintaihua Hardware Products Co., Ltd. has 20 years of experience in professional production of metal stamping, which is trustworthy) as far as the quality identification of hardware accessories is concerned, it can be identified by the feel, finish, matching gap, etc. of the products. Qualified users should purchase the hardware accessories manufactured by regular manufacturers, because most of the regular manufacturers use mold processing, with product accuracy It has the characteristics of high quality, good dimensional consistency and standard processing technology. Decorative cabinet hardware accessories, such as cabinet handle, should be considered and furniture color, texture coordination. Cupboard handle should not use solid wood handle, otherwise in the humid environment, the handle is easy to deform. The solid wood cabinet can choose the antique handle, which is made of zinc alloy and other materials, as well as the engineering plastics pressed by the mold. The patterns on its surface can be made very meticulous and delicate, and after the surface treatment, it can match the wood completely, with good effect.

Therefore, before the purchase of hardware accessories, the relevant reference materials that can be mastered or understood, for consumers, can not only choose hardware accessories that meet their own needs, but also enjoy high-quality life fun. The design of hardware stamping parts factory should not only ensure good use performance, but also have good process performance, in order to reduce material consumption, extend die life, improve productivity, reduce cost and ensure the quality of stamping parts.

Compared with castings and forgings, metal stamping parts are thin, uniform, light and strong. The workpiece with stiffener, rib, undulation or flanging, which is difficult to be manufactured by other methods, can be manufactured by stamping to improve its rigidity. Due to the use of precision die, the precision of workpiece can reach micron level, and the repetition precision is high, the specification is consistent, and the hole and socket, boss, etc. can be punched.

More time is needed for mold design and manufacturing, which prolongs the production preparation time of new hardware stamping parts The standardization of die base, die base and guide parts, the development of simple die (for small batch production), compound die, multi position progressive die (for large batch production), and the development of rapid die change device can reduce the preparation workload and time for stamping production, reduce the preparation workload and time for stamping production, and enable the advanced stamping technology for large batch production It can be used in small batch and multi variety production. In addition to forming thick plates by water press, stamping equipment generally adopts mechanical press. The automatic stamping production line with high productivity can be made up of conveying and other machines, mold library and rapid die change device, and controlled by computer program In the case of producing tens or hundreds of metal stamping parts per minute, the processes of material feeding, stamping, part discharging and waste discharging are completed in a short period of time, often resulting in personal, equipment and quality accidents.
