Custom Lock Hardware Manufacturer

China Simis Company specializes in the custom manufacturing of Precision Lock Hardware Parts, serving the architectural, security, and industrial control sectors. Lock hardware components (including the lock body, cylinder, latch, strike plate, and faceplate) are highly mechanical devices that must function reliably over tens of thousands of cycles while providing uncompromising security against tampering.

Our capabilities span multiple casting techniques and alloys—from Investment Casting for high-strength Stainless Steel components (critical security and external applications) to Die Casting for precision Zinc and Aluminum Alloys (intricate cylinders and aesthetic housings). We ensure the final product delivers the tight tolerances required for smooth mechanical action, the durability for long service life, and the material integrity required for security.

1. Lock Hardware Component Classification

Lock hardware parts are classified based on their function within the locking system, categorized primarily into three areas: Structural & Security, Driving & Operation, and Aesthetic & Integration.

2. Core Manufacturing Processes: Precision and Material Versatility

The choice of casting method is driven by the material's properties and the part's requirement for internal complexity, strength, and finish.

3. Material: Security, Durability, and Aesthetics

The material is selected to match the required functional performance (security) and environmental exposure (corrosion).

4. Quality Assurance: Functionality and Security

QA focuses intensely on dimensional accuracy for function and material integrity for security.

·Dimensional and Tolerance Inspection: 

Mandatory CMM checks on critical interfaces (e.g., cylinder bore, keyway, latch throw) to ensure smooth, reliable mechanical cycling.

·Cycling Life Testing: 

Simulated testing of the final assembly (or critical components) to ensure the lock can withstand tens of thousands of open/close cycles without failure or excessive wear.

·Corrosion Resistance Testing: 

Salt spray testing of coated steel and zinc components to verify compliance with ASTM or ISO standards for environmental durability.

·Non-Destructive Testing (NDT): 

Used on high-security steel components to check for internal defects that could compromise the lock's integrity against physical attacks.

5. Application Areas: Access Control and Security

6. Advantages of Simis Custom Lock Hardware

Simis provides cast lock hardware that balances security integrity, mechanical precision, and cost efficiency across diverse applications.

·High Precision for Smooth Operation: 

Leveraging Die Casting and CNC machining ensures the tight dimensional tolerances required for effortless key rotation and reliable latch engagement.

·Tailored Material Security: 

We guide the selection of the correct material (e.g., Stainless Steel Investment Casting for maximum security, Zinc Die Casting for precision housing) to meet security ratings and environmental demands.

·Excellent Surface Finish: 

Expertise in Die Casting and surface treatment allows for a polished, ready-to-plate finish for aesthetic components, reducing post-processing costs.

·Structural Soundness: 

NDT procedures on load-bearing/security components guarantee the internal integrity necessary to resist forcing and tampering.
