Product Description

The Machine Drive Involute Transmission Precision Injection Plastic Helical Cylindrical Worm Gear Wheel is a customized injection and machining gear. It is made using materials like Nylon, PA66, ABS, PP, PC, PE, POM, PVC, PU, TPR, TPE, TPU, PA, PET, HDPE, PMMA, and more. The gear undergoes a quality control process to ensure its precision and meets industry standards such as AGMA, JIS, and DIN. It can be surface-treated with blackening, plating, anodizing, hard anodizing, and more. The gear’s hardness ranges from 30 to 60 H.R.C, and its size and color can be customized according to customer drawings. The dimensions tolerance is ±0.01mm or more precise. Samples are available for confirmation before bulk production.

Production Management

1. Our workers are trained to inspect gears and identify any defects during production.
2. Every 100 pieces of gears in CNC machining are checked by QC to ensure they meet all dimension tolerances.
3. Gears are inspected at every step and before shipment. All inspection records are kept for three years.
4. Our sales team provides pictures of the production process to keep customers informed and ensure accuracy.
5. We prioritize the quality of our products and value every inquiry and customer.

Quality Control Process

1. Inspecting the raw material (IQC) to ensure its quality.
2. Checking the details before the production line is operated.
3. Conducting full inspection and routing inspection during mass production (IPQC).
4. Checking the gears after production is finished (FQC).
5. Conducting outgoing quality control (OQC) to ensure the gears meet the required standards.


1. We design molds based on customer’s gear drawings.
2. Molds drawings are submitted to customers for review and confirmation before production.
3. We provide samples with dimensions and cosmetic inspection reports, along with material certification.
4. Inspection reports of important dimensions and cosmetic features are provided for batch parts.

Packing and Shipment

1. Gears are carefully packed in PP bags in cartons, suitable for express shipping, air shipment, or sea shipment.
2. Shipping methods include UPS, DHL, FedEx, TNT, air shipment, sea shipment, or according to customer requirements.
3. Trade terms: EXW, FOB Shenzhen, or CIF.
4. We ensure that all shipments are carefully arranged and reach their destinations quickly and safely.
