Door Lock

This door lock is a metal structural component of a lock hook stopper, custom-formed using powder metallurgy technology, specifically manufactured for smart lock accessories. The door lock part is designed and optimized based on the internal space and functional requirements of the lock body. By selecting suitable iron-based or alloy powders, and using precision molds for pressing and high-temperature sintering, a near-net-shape final part with specific shape, dimensional accuracy, hardness, and mechanical properties is obtained, allowing for direct assembly and use without extensive secondary processing.

Product Parameter (Specification)

Product Feature And Application

(1) Excellent Material Performance and Wear Resistance

The homogeneous microporous structure formed by sintering can store lubricating oil, enabling self-lubrication and reducing friction and wear. Through material formula adjustment and heat treatment, high hardness (up to HRC 25-35) and good toughness can be achieved, significantly improving the impact resistance and wear resistance of the stopper surface and ensuring long-term reliability.

(2) Superior Dimensional Accuracy and Batch Consistency

Mold forming ensures extremely high dimensional repeatability of parts (key dimensional tolerances can reach ±0.03mm), ensuring stable clearance with the lock hook and precise and accurate operation. Consistent quality between batches provides a solid foundation for part interchangeability and large-scale, automated assembly of smart locks.

(3) Significant Cost and Efficiency Advantages

Near-net shaping greatly reduces raw material waste and subsequent machining, with material utilization approaching 100%, resulting in a 30%-50% reduction in overall cost compared to full machining.

High production efficiency makes it suitable for medium to large-scale production and allows for quick response to market demands.
