Electric shaver gears
Electric shaver gears Applications and Precision Gear Manufacturing
UNITECH-GEAR specializes in precision gear mold design and micro precision injection molding for electric shaver transmission gears, sonic toothbrush gear modules, electric oral irrigator motor modules, massager motor modules, and fascia gun motor modules.
Achieving optimal shaving requires the cutter foil to perfectly conform to skin while cutter heads rotate at high speed for clean cutting. In multi-head designs from brands like Philips, Flyco, Braun, and Panasonic, plastic gears are extensively used. The motor drives the main gear, which sequentially transfers rotation to other driven gears for each cutter head.
UNITECH-GEAR's plastic gear solutions reduce noise, lower current draw for extended battery life, and minimize wear for longer product lifespan. Our solutions increase rotational speed for improved cutting performance while reducing shaft-gear wear for extended service life.
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.
