Precision Power Transmission Solutions

Compound transmission gears are essential components in modern industrial power systems. These gears efficiently transfer torque and rotational motion in compact mechanical systems. We manufacture compound transmission gears ranging from miniature sizes to large-scale models. This wide product range meets different equipment requirements across multiple industries. Our machining capabilities cover outer diameters from Φ5 mm to Φ300 mm. This means we can supply suitable gear solutions for both precision instruments and heavy machinery. Our customers trust us to deliver consistent performance across their complete equipment systems.

Strict Quality Standards for Long-Term Reliability

We focus on the long-term operational reliability of every gear we produce. Our manufacturing processes strictly follow international gear precision standards. These include German DIN and American AGMA gear standards. For miniature gears, we achieve Grade 6 precision with dimensional tolerances of ±0.005 mm. The tooth surface roughness reaches Ra 0.4 μm or better. This high precision ensures quieter operation and smoother power transmission during high-speed rotation. For larger gears, we guarantee Grade 8 precision with Ra 1.6 μm tooth surface quality. Every gear undergoes strict inspection to verify these critical parameters before shipment.

Advanced Manufacturing and Quality Control Systems

Our facility has over 15 years of experience in precision machining. We operate Hehai/DeMA 5-axis simultaneous machining centers and Tsugami Swiss-type automatic lathes for high-precision manufacturing. These Japanese-made high-end machines ensure exceptional accuracy on every part. Our digital production management system records and tracks data from every processing step. This complete traceability helps us maintain consistent quality across all production batches. We follow the "Three No" quality principle throughout our operations. This means we do not produce, accept, or release defective products. Our quality control covers incoming material inspection (IQC), in-process inspection (IPQC), and final quality control (FQC). Our compound transmission gears are manufactured under strict quality control systems to ensure stable performance for demanding industrial applications. This systematic approach to quality management enables us to support demanding global brands.
