Limited Block

The limited blocks are all manufactured using powder metallurgy near-net shaping technology, achieving a material utilization rate of over 95%.  Adhering to ISO 9001quality management system and IATF 16949 process control standards, we provide full-process technical services, from design support and rapid prototyping to mass production. Guangzhou Guangming Metal Products Co.,Ltd's limited blocks components are made of iron-based alloy material,and through high-precision molds and blackening treatment processes, precise control is achieved according to the dimensional accuracy requirements of the drawings.

Product Parameter (Specification)

Product Feature And Application

(1) High Integration and Integrated Structure and Function

Complex three-dimensional structures (such as multi-step surfaces, irregular holes, and thin-walled reinforcing ribs) can be formed in a single pressing process, achieving integrated functions of blocking, guiding, positioning, and weight reduction, optimizing the internal layout of the lock body and improving space utilization.

(2) Excellent 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 error-free operation.

(3) Significant Cost and Efficiency Advantages

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

High production efficiency is suitable for medium to large-scale production, enabling quick response to market demands.

(4) Lightweighting and Strength Optimization

By designing internal cavities and optimizing wall thickness, effective weight reduction can be achieved while ensuring structural strength, contributing to the overall lightweight design of smart locks.
