Production Management

Our production process ensures high-quality gears. The workers are trained to inspect the gears and identify any defects during production. Quality control (QC) checks 1 piece every 100 pieces in CNC machining, ensuring that the gears meet all dimension tolerances. Gears are inspected at every step, and a final inspection is conducted before shipment. All inspection records are kept for three years. Our sales team provides regular updates on the production status and pays close attention to every detail.

Quality Control Process

Our quality control process includes inspecting the raw materials (IQC), checking the details before production, conducting full inspections and routing inspections during mass production (IPQC), checking the gears after production finishes (FQC), and conducting outgoing quality control (OQC) checks before shipping.


Our services include designing molds based on customers’ gear drawings, submitting mold drawings for review and confirmation, providing samples with dimensions and cosmetic inspection reports, and offering material certifications. We also provide inspection reports for batches of parts.

Packing and Shipment

The gears are carefully packed in PP bags in cartons, ensuring they are strong enough for express shipping, air shipment, or sea shipment. We offer various shipping options such as UPS, DHL, FedEx, TNT, and sea shipping. Our trade terms include EXW, FOB Shenzhen, or CIF.
