Dimensional Configurations
Standard Lengths: Symmetric configurations from 60 mm (30/30) up to 120 mm (60/60). Asymmetric steps in 5 mm increments (e.g., 30/35, 35/45, 40/50).
Tolerance Control: CNC lathe turning and milling tolerances maintained within +/-0.02 mm to prevent binding in mortise lock bodies.
Emergency Function: Available with clutch/emergency function (operable from outside even if a key is inserted inside) upon specification.
Manufacturing & Quality Control
Material Processing & Forging
Extruded brass bars undergo spectral analysis to verify copper and lead content ratios prior to multi-axis CNC milling.
Plugs and shells are broached on dedicated vertical broaching machines to maintain core pin-hole alignment tolerances under 0.015 mm.
Surface Treatment & Plating
• Multi-layer electroplating: Copper flash (5 um) followed by Nickel (12 um) and Chrome/Brass finishing.
• Salt spray test resistance: Minimum 96 hours to 240 hours neutral salt spray (NSS) depending on surface finish grade.
Testing & Inspection
• Torque Testing: Cam shear-strength tested to withstand torque loads exceeding 15 Nm.
• Pull Testing: Plug extraction force tested up to 2.5 kN.
• 100% Functional Gauging: Every assembled cylinder is tested on automated air-gauge fixtures for key insertion smoothness and pin alignment verification.
Application Guide
Commercial Mortise Locks: Designed for integration with standard Euro mortise lockcases used in aluminum, steel, and timber doors.
Master Key Systems (MK / GMK): Compatible with complex hierarchical key charts supporting up to 4 levels of master keying without compromising pick resistance.
Retrofit & Maintenance: Direct drop-in replacement for existing DIN-standard installations in office buildings, educational facilities, and hospitality projects.

Packaging Standards: Available in industrial bulk master cartons (protective compartmentalized trays for assembly plants) or individual visual boxes/blister packs for wholesale distribution. Minimum Order Quantity (MOQ) starts at 500 units per size/finish variant for standard specs.
Certifications: ISO 9001:2015 quality management system; CE marked in accordance with Construction Products Regulation (CPR) EN 1303.
Frequently Asked Questions
Q: What keying options are available for bulk orders?
A: Cylinders can be supplied Keyed Different (KD), Keyed Alike (KA) in specific batch groupings, or built to custom Master Key (MK) and Grand Master Key (GMK) charts. Key codes are tracked securely to prevent unauthorized duplication.
Q: How do you prevent key bitting cross-contamination in large orders?
A: Bitting combinations are computer-generated using restricted mathematical algorithms to ensure zero key duplication within specified batch sizes.
Q: What is the standard lead time for OEM orders?
A: Standard production lead time ranges from 30 to 45 days following technical drawing sign-off and order confirmation. Stock components for standard sizes (30/30, 30/35) are maintained for expedited sample dispatch.
Q: Are anti-snap bars available for high-security applications?
A: Yes. Reinforced steel bridges or sacrificial break-off score lines can be incorporated into the cylinder body to resist mechanical snapping attacks, meeting EN 1303 attack resistance requirements.
