Material & Manufacturing Process
Reliable field performance relies on controlled metallurgy, precision tooling, and strict quality verification.
Die-Casting Precision: Components are produced using multi-slide hot-chamber die-casting machines with automated shot monitoring, maintaining dimensional stability within +/- 0.05 mm to eliminate assembly misalignment on production lines.
Surface Treatment Line: Multi-stage ultrasonic degreasing followed by automated electrostatic powder coating or electroplating, ensuring uniform film thickness (60-80 um) and strong inter-coat adhesion.
Heat Treatment & Hardening: Internal hook bolts undergo carbonitriding heat treatment to achieve a core hardness of HRC 38-42, resisting hacksaw cutting and frontal impact forces.
Application & System Compatibility
These locking solutions integrate into multiple architectural profile systems:
Aluminum Patio Doors: Designed for standard Euro-groove and C-channel aluminum sliding door extrusions in residential and hospitality projects.
Commercial Storefront Sliding Entrances: Heavy-duty hook bolt configurations designed for high-frequency retail and office entries requiring anti-lift security, utilizing robust commercial sliding door mortise lock designs.
Frameless & Semi-Frameless Glass Sliders: Low-profile latch assemblies compatible with patch fittings and bottom-rail sliding configurations.
Quality Control & Factory Testing
Every production batch undergoes strict testing before export to minimize field failures and warranty claims.
Salt Spray Testing: Continuous exposure in a salt fog chamber for 500 hours to verify oxidation resistance for coastal and humid environments.
Torque & Pull Testing: Digital force gauges measure the shear resistance of the hook bolt under lateral loads exceeding 3,000 N.
Dimensional Verification: Coordinate Measuring Machines (CMM) inspect critical mounting holes, backset depths, and cylinder clearances on a strict AQL 1.0 sampling plan.
Buyer Decision & Sourcing Guide
When evaluating sliding glass door lock suppliers for volume procurement, consider the following technical factors:
Verify Profile Fitment: Request physical engineering drawings (PDF/STEP files) to cross-reference your extrusion channel dimensions and backset requirements before sample testing.
Confirm Finish Durability: For coastal installations, verify that the salt spray test report matches your project specifications (e.g., minimum 500 hours for architectural grade).
Evaluate Packaging for Bulk Transit: Ensure individual blister or industrial bulk packaging uses anti-scratch interleaving to prevent surface damage during ocean freight.
Frequently Asked Questions
Q: What are the standard backset options available for custom aluminum profiles?
A: Standard production runs support 45 mm, 50 mm, and 55 mm backsets. Custom backset dimensions and non-standard faceplate lengths can be tooled according to your extrusion drawings with an initial sample lead time of 15 days.
Q: Are the lock handles and cylinders reversible for left-hand and right-hand sliding doors?
A: Yes. Most hook-bolt and latch configurations feature a non-handed or field-reversible latch mechanism, allowing installers to adjust orientation on-site.
Q: What is the standard Minimum Order Quantity (MOQ) for OEM finishes?
A: Standard finishes (Satin Nickel, Black powder coat) have an MOQ of 500 sets per item. Custom RAL color matching or specialized plating requires an MOQ of 1,000 sets per batch.
Q: What documentation is provided with commercial shipments?
A: Each shipment includes a Material Test Report (MTR) for raw metals, salt spray test certificates, dimensional inspection sheets, and a Certificate of Conformance (CoC).
