Powder metallurgy products are mechanical parts and various metal products made of metal powder (iron powder, colored metal powder) through mixing, pressing, sintering and subsequent processing, which belong to high-tech products. Technology is advancing, technology is innovating, and green sustainable development has always been the goal pursued by the times. In the metal forming industry, powder metallurgy is recognized as a green technology. Powder metallurgy technology can be used to manufacture complex shapes, high-strength, and high-precision mechanical parts that are difficult to manufacture by traditional techniques. It has the characteristics of less, no cutting, material saving, energy saving, and high efficiency.
Powder metallurgy is a technology for metal forming process by heating and compacting metal powder below its melting point. It has advantages in shape and size control. Dongguan Chenghua Powder Metallurgy Co., Ltd. is an enterprise specializing in R&D and production of powder metallurgy parts. The company has fully invested in R&D and production during the development process. Perfect functional characteristics of the product. At present, the company's products mainly include stainless steel precision powder metallurgy parts, powder metallurgy oil bearings, powder metallurgy smart lock parts, powder metallurgy lock accessories, powder metallurgy pneumatic tool parts, black powder metallurgy parts, oil bearing bushings, spiral teeth, bevel teeth, etc. .
During the development process, Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. uses various forming processes to directly form powder raw materials into blanks or net-shape parts with little or no margin, which greatly reduces the amount of machining, improves material utilization, and reduces cost. Among them, the structure of the tooth surface of the helical gear is complex, and its special purpose and excellent meshing performance have very strict requirements on the geometric accuracy and meshing quality of the tooth surface. However, the helical gear produced by Zhongwei Precision has a large number of teeth in contact with the transmission, and the uniform transmission noise is relatively low. It is small and can transmit large power. It can be used in the case where the two axes are parallel to each other or the two axes are at any angle without intersecting. Therefore, it is widely used in various industries and has been well received by many users.
Powder metallurgy processing technology has been widely used in the fields of machinery, transportation, electronics, aerospace, weapons, nuclear industry, biology, information, environmental protection and energy saving, and has become the most dynamic branch of new material science. In recent years, the global manufacturing industry is accelerating the transfer to China. The rapid development of the automobile industry, machinery manufacturing, metal industry, aerospace, instrumentation, hardware tools, engineering machinery, electronic appliances and high-tech industries has brought powder metallurgy industry Rare opportunities for development and huge market space. In addition, the powder metallurgy industry has been included in China's priority development and foreign investment projects, and its development prospects are very broad. Dongguan Chenghua Powder Metallurgy will continue to accumulate rich experience, specialized professionals, and complete and reliable records in the future development. It will be the partner sought by customers and is determined to provide you with high-quality, high-quality products Powder metallurgy parts.
