With the continuous progress and industrialization of powder metallurgy technology, the application of powder metallurgy parts in the lock industry has played an important role in promoting. At present, my country's lock industry is in a vigorous development stage. According to industry statistics, China's smart door lock market has more than 1,500 merchants and 3,500 brands. All kinds of smart locks are widely used in major residential areas and industry markets. Vast, its corresponding internal components such as powder metallurgy gears, bearings, etc. have a huge market demand, so it also brings rare market opportunities to my country's powder metallurgy parts manufacturing enterprises.
For the processing and customization of powder metallurgy lock fittings, among PM powder metallurgy manufacturers, Weiji has rich project practical experience. In the manufacture of smart lock parts, its main production and processing products include smart lock gearbox oil bearing, smart lock pinion, smart lock gearbox gear, smart cabinet lock hook lever, smart cabinet lock accessories, smart lock fork , smart lock accessories, lock cylinders, etc., all adopt precision powder metallurgy technology, which endows the parts with excellent corrosion resistance and anti-aging performance, far exceeding the locks of ordinary carbon steel parts, helping smart lock merchants to provide users with more convenient and intelligent products. Security has become an ideal choice for the market.
Zhongwei strictly implements the processes of raw material mixing, forming, degreasing and sintering, subsequent processing, and finished product inspection, and ingeniously manufactures smart lock series parts, with a product qualification rate of over 98%. Zhongwei precision powder metallurgy does not require or only requires a small amount of machining, and can produce complex or strange shaped parts, mass production, good consistency, high precision, and material composition can be adjusted according to the performance requirements of customer parts, which is unmatched by other processes processing advantages.
It is understood that Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. was founded in 1997. It cooperates with the Powder Metallurgy Research Institute of Central South University, focusing on the research and development of powder metallurgy PM and MIM technology, and providing customers with various high-precision and complex mechanical hardware parts powder metallurgy. Products, and provide professional advice according to customer needs, customize the overall solution to help customers improve efficiency and save costs. With 22 years of industry application experience, Zhongwei Precision has developed 6,000+ product varieties and customized 3,300+ sets of molds, which can meet various shapes, materials, and applications. Its powder metallurgy products have high precision, uniform structure, and excellent performance. Production Low cost and other characteristics have won the favor and trust of many industries such as the automobile industry, lock industry, mechanical equipment, hardware accessories, electric products, household appliances, etc. Among them, the lock industry includes General Lock Industry, Wanjia Group, Sanhuan Lock Industry They are all partners of Zhongwei Precision.
At present, the era of intelligence has come, and locks are closely connected with human life, and the industry has also undergone tremendous changes. The emergence of smart locks has made consumers extremely demanding on the precision, life, and wear resistance of their parts. Moreover, the structure and shape of some parts are complex, and the traditional process is high in cost, low in efficiency and difficult. The powder metallurgy PM pressing method will become a new choice. Next, Zhongwei Precision will also rely on strict quality management concepts, high-quality talents and the spirit of continuous improvement to provide better products and services for customer partners in the smart lock industry.
