Material Composition & Manufacturing Process
Body Material: Forged from high-purity brass alloy (HPb59-1), preventing internal micro-cracks and providing structural rigidity against physical shear attacks.
Plug & Pins: Precision-turned brass plugs paired with nickel-plated steel bottom pins and anti-pick mushroom driver pins.
Cam Production: Powder metallurgy sintered steel cam, hardened to HRC 50-55 to withstand torque wrench attacks and repetitive actuation stress.
Surface Finishing: Multi-layer electroplating passing 96-hour neutral salt spray testing (NSS) for exterior and coastal architectural deployments.
Keying Systems & Master Key Capabilities
Project orders require flexible locking hierarchies. Factory-configured keying options include:
Key Different (KD): Each cylinder operates with its own unique key set.
Key Alike (KA): Multiple cylinders operate with the same key, minimizing keyring bulk for facility managers.
Master Key System (MK): Individual doors have unique keys, while a designated master key overrides all cylinders within a specific zone.
Grand Master Key System (GMK): Hierarchical grouping across multi-building facility complexes.
Application Suitability
Commercial Office Parks: Interior office partitions, server rooms, and perimeter security doors utilizing DIN mortise locks.
Multi-Family Residential: Main entrance gates and individual apartment entry doors.
Institutional Facilities: Universities, hospitals, and government buildings requiring audited master-key hierarchy.
Quality Control & Testing Protocols
Torque Resistance Test: Exerting a rotational force up to 15 N·m on the plug to verify shear pin integrity.
Pull & Break Test: Applying a tensile load of 15 kN to the cylinder body to evaluate anti-snap structural performance.
Cycle Life Test: Automated pneumatic rigs cycle each cylinder configuration past 100,000 continuous rotations under load.
Gauge Inspection: 100% optical and Go/No-Go plug gauge inspection for keyway and pin chamber alignment tolerances.
Frequently Asked Questions
Q: What are the minimum order quantities (MOQ) for custom keyway profiles?
A: For standard stock profiles (e.g., standard Euro profile), MOQ starts at 500 pieces. For proprietary restricted keyways requiring custom broaching tools, MOQ is 2,000 pieces per project batch.
Q: Can these cylinders be integrated into an existing Master Key system?
A: Yes. Provide your current bitting list or key chart specifications. Our engineering team matches pin depth increments and blank profiles to maintain compatibility with your installed hardware framework.
Q: What emergency egress or clutch functions are available?
A: Standard models require internal key engagement if locked from outside. Emergency function (double-side operable even with a key inserted inside) and thumbturn configurations are available on request.
Q: What documentation is supplied with bulk shipments?
A: Each shipment includes individual test reports, material mill certificates for HPb59-1 brass, dimensional inspection sheets, and batch traceability barcodes.
