CNC Machining Strength
Single-Process Accuracy for Complex Cylinder Components
Lock cylinders depend on the accurate relationship between the plug, shell, pin holes, keyway, cam, tailpiece, and multiple security elements. EOSYS uses Swiss-type CNC machining to complete complex components with fewer transfers, reducing cumulative errors often caused by multi-machine processing.
Higher Dimensional Consistency
Precision-controlled machining helps maintain stable dimensions across large production batches, supporting consistent assembly and key operation.
Smoother Mechanical Performance
Accurate component matching improves turning smoothness, reduces friction, and supports a premium operating feel for professional lock brands.
Better Security Structure Support
High-precision machining enables anti-pick, anti-bump, anti-drill, anti-snap, and restricted keyway designs with reliable structural execution.
Stable Mass Production
Mature manufacturing procedures, controlled fixtures, and documented inspection standards help maintain repeatable output for global OEM projects.
Factory Scale
Built for Reliable OEM and Project Supply
EOSYS operates a 7,000㎡ production base with approximately 200 skilled employees and an annual output value exceeding RMB 100 million. The facility supports scalable production for distributors, lock brands, door hardware manufacturers, locksmith channels, and project-driven integrators.
Advanced 6S Management
Organized production flow improves efficiency, traceability, and workshop stability.
Audited by Leading Brands
EOSYS has passed factory audits from recognized domestic and international brands.
Quality Consistency
Precision Is Controlled Before, During, and After Production
EOSYS precision machining is supported by a structured quality workflow. From material verification and first article inspection to interval audits and final inspection, each stage is designed to protect component accuracy and functional reliability.
Incoming Material Inspection
Raw materials are checked for composition, dimensions, straightness, and conformity before entering production.
First Article and Process Audits
Key dimensions are confirmed before mass production, with interval inspections during production to protect consistency.
Tooling Control Management
Tooling is inspected, documented, and replaced according to controlled standards to avoid accuracy loss during batch production.
EN1303-Oriented Testing Capability
In-House Laboratory Support for European Security Requirements
EOSYS operates an in-house laboratory capable of performing tests according to EN1303 standards, supporting technical validation for high-security cylinders and customized product development.
