Technical FAQ
Q
Can you manufacture gears with completely irregular shapes and custom keyways?
Absolutely. Our core strength lies in 100% custom production. As long as you provide the CAD models or technical drawings, our engineering team will design the precise tooling required to manufacture your custom and irregular gears.
Q
Why choose POM over other plastics for gearbox applications?
POM (Polyoxymethylene) is highly crystalline, offering excellent tensile strength, outstanding fatigue resistance, and a very low coefficient of friction. This makes it the ideal plastic for high-load, continuous-movement applications like gearboxes.
Q
How do you guarantee the quality of custom orders?
We are an ISO 9001 certified manufacturer. From raw material inspection to first-article approval and final rigorous batch testing, our comprehensive quality control ensures every gear meets your exact tolerance and performance requirements.
Q
What is the typical lead time for a new custom gear project?
Lead times depend on the complexity of the mold design. Typically, mold development and prototyping take 15–25 days, followed by rapid mass production upon your final approval of the samples.

Frequently Asked Questions
Q
What materials other than POM can you use for custom plastic gears?
While POM is our primary material for gearbox applications, we also work with other engineering plastics such as Nylon (PA6/PA66), PEEK, and PPS depending on the specific load, temperature, and chemical resistance requirements of your application. Contact our engineering team to discuss the best material for your project.
Q
What file formats do you accept for custom gear design submissions?
We accept all standard CAD formats including STEP, IGES, SolidWorks (.sldprt), AutoCAD (.dwg/.dxf), and PDF technical drawings. Our engineering team can also work from physical samples or detailed dimensional sketches for reverse engineering purposes.
Q
What is the minimum order quantity (MOQ) for custom plastic gears?
Our MOQ varies depending on the complexity of the mold and the gear specifications. For new custom tooling projects, we typically start from small prototype batches to validate the design, followed by scalable production runs. Please contact us with your requirements for a tailored MOQ and pricing offer.
Q
Can plastic gears truly replace metal gears in heavy-duty gearbox applications?
Yes, in many applications. High-performance engineering plastics like POM offer an excellent strength-to-weight ratio, self-lubrication, and corrosion immunity. They are particularly advantageous where noise reduction, weight savings, and elimination of external lubrication are priorities. Our engineers can assess your specific load and speed parameters to confirm suitability.
Q
Do you offer surface treatment or post-processing options for plastic gears?
Yes. Beyond standard injection molding, we offer secondary operations including precision CNC machining, grinding for tight tolerances, and surface finishing. These post-processing steps ensure that gears meet the exact dimensional and functional requirements for demanding transmission applications.
Q
How do you handle international shipping and export documentation?
We are experienced in international B2B export from Shenzhen, China. We handle all necessary export documentation including commercial invoices, packing lists, and certificates of origin. We work with major freight forwarders and can support FOB, CIF, and EXW shipping terms based on your preference.
