Technical FAQ
Q
Can you manufacture gears with completely irregular shapes and custom keyways?
A: 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?
A: 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?
A: 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?
A: 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
Q1
What materials are used in your custom plastic gears, and why is POM preferred?
Our custom gears are primarily manufactured from POM (Polyoxymethylene), a high-performance engineering plastic known for its exceptional stiffness, low coefficient of friction, and outstanding fatigue resistance. Compared to nylon or other engineering plastics, POM offers superior dimensional stability and is far less susceptible to moisture absorption, making it the preferred choice for precision gearbox and transmission applications.
Q2
What are the advantages of using plastic gears instead of metal gears in transmission systems?
Plastic gears offer several key advantages over metal alternatives: they are significantly lighter, self-lubricating (reducing maintenance costs), operate more quietly, and absorb vibration and shock loads more effectively. In many industrial applications, this translates to lower energy consumption, longer service life for surrounding components, and reduced overall system noise levels.
Q3
What file formats do you accept for custom gear design submissions?
We accept a wide range of standard engineering file formats including STEP (.stp), IGES (.igs), SolidWorks (.sldprt), AutoCAD (.dwg/.dxf), and PDF technical drawings. If you only have a physical sample, we can also reverse-engineer the part using precision measurement tools to create the required tooling.
Q4
What is the minimum order quantity (MOQ) for custom plastic gears?
MOQ varies depending on the complexity of the mold and the gear specifications. For custom injection-molded gears, we generally recommend a minimum order that justifies the tooling investment. We are happy to discuss your specific volume requirements and offer scalable solutions from prototype batches through to full mass production runs.
Q5
Can your plastic gears withstand high temperatures or harsh chemical environments?
Standard POM gears perform reliably within a temperature range of approximately -40°C to +120°C. For applications requiring higher thermal resistance or chemical compatibility, we can work with alternative engineering plastics such as POM-C, PA66+GF (glass-filled nylon), or PEEK. Please share your operating environment details so we can recommend the most suitable material.
Q6
Do you offer OEM and private label manufacturing services?
Yes, we provide full OEM and ODM services. All custom gears can be produced under your brand name with customized packaging. Our team works closely with clients throughout the entire product development cycle — from initial DFM (Design for Manufacturability) review to final delivery — ensuring complete confidentiality and intellectual property protection.
