Samples are shipped for confirmation, and the shipping cost is paid by the customers. The gear is carefully packaged to ensure safe delivery. The total delivery time usually takes 2-8 weeks.

Production Management

1. Workers are trained to inspect the gears during production to detect any defects.
2. Quality control (QC) checks 1 piece out of every 100 pieces during CNC machining to ensure dimensional tolerances are met.
3. Gears are inspected at every step of the production process, and final inspection is conducted before shipment. All inspection records are kept for three years.
4. Sales representatives provide updates and pictures of the gears at each production stage, allowing customers to monitor the process and identify any potential mistakes.
5. Our team is committed to delivering high-quality products and providing excellent customer service.

Quality Control Process

1) Inspecting the raw material (IQC)
2) Checking the details before the production line operates
3) Conducting full inspection and routing inspection during mass production (IPQC)
4) Checking the gears after production is finished (FQC)
5) Checking the gears again before shipping (OQC)


1. We design molds based on customer’s gear drawings and submit them for review and confirmation before production.
2. We provide samples with detailed dimensions, cosmetic inspection reports, and material certifications.
3. We provide inspection reports for important dimensions and cosmetic features of batch parts.

Packing and Shipment

1. The gears are carefully packed in PP bags and CTNS, ensuring they are strong enough for express shipping, air shipment, or sea shipment.
2. We offer various shipping options, including UPS, DHL, FedEx, TNT, and sea shipment.
