Central locking gearbox
Central locking gearbox Applications and Precision Gear Manufacturing
Central locking gearboxes are widely used in automotive door lock actuators, featuring high torque, stable transmission, and long-lasting durability.
We select premium imported raw materials and employ proven mold design and project management experience, supported by advanced processing equipment and Japanese all-electric precision injection molding machines ranging from 30 to 120 tons with advanced 5-axis robots. We specialize in various precision plastic gear molding, including weather-resistant gears, wear-resistant gears, and angle conversion gears.
Full-process precision control ensures quality from source, with professional QC personnel and advanced inspection equipment. Production includes FQC first-article inspection, IPQC in-process inspection, OQC outgoing inspection, and 100% inspection for special products, ensuring delivered products meet all customer quality requirements.
UNITECH-GEAR Gears — High Precision, Low Noise, Long-Lasting Durability
Mastering Core Manufacturing Technology — Pursuing Excellence
Design-Driven, Analysis-FocusedExperienced Engineers Optimize Tooth Profile Design
- Gear design analysis software optimizes tooth profiles, improving safety factors and service life.
- Close communication with customers to understand product functional requirements including material selection, mechanical strength, dimensional accuracy, surface finish, and service life.
- Rigorous design review process: pre-design structural discussion, designer self-inspection against checklists, and post-design review with manufacturing teams.
Processing-Driven, Precision-FocusedFrom Mold Design to Injection Molding — Precision Manufacturing
- Independent machining department for copper electrode (EDM electrode) design and manufacturing. Post-machining copper electrode surface roughness reaches Ra 0.3, accuracy up to JIS Grade 0 (highest level).
- Mold cavity mirror finishing using Charmilles C-axis EDM, achieving surface roughness of Ra 0.3 and accuracy within 0.001mm.
- Japanese brand high-precision injection molding machines produce gears with dimensional tolerances within 0.03mm and weight deviation typically below 0.7%.
Detail-Driven, Control-Focused100% Visual Inspection — Full Testing Before Shipment
- Advanced inspection equipment: gear meshing testers, CMM (Coordinate Measuring Machines), roundness testers, and electron microscopes ensure product quality.
- Strict implementation of ISO 9001 quality management system ensures all products meet customer requirements.
- All gear products undergo 100% visual inspection before assembly, and all gearboxes are fully tested before shipment.
