Frequently Asked Questions
Q
What material are your plastic worm gears made from, and why does it matter?
Our plastic worm gears are manufactured using DuPont engineering-grade materials sourced from the United States. This ensures superior mechanical strength, thermal stability, and consistent dimensional accuracy of ±0.02mm — far exceeding standard industry tolerances and making them suitable for precision-critical applications.
Q
How long can the worm gear operate without additional lubrication?
Thanks to our patented self-lubrication technology integrated into the material and design, the worm gear can operate continuously for up to 10,000 hours without requiring any additional lubrication. This significantly reduces maintenance costs and downtime in industrial applications.
Q
Are anti-static or conductive grade options available for electronic device applications?
Yes. We offer optional conductive grade and anti-static grade material variants specifically designed to meet the electrostatic discharge (ESD) requirements of sensitive electronic equipment, including medical devices and precision instruments.
Q
What standard specifications are available in stock, and can custom sizes be ordered?
We maintain ready inventory for the three mainstream module specifications: M1.0, M1.5, and M2.0. For custom or non-standard parameters, we support rapid mold opening within 30 days, enabling flexible and efficient production tailored to your specific requirements.
Q
What quality testing does each product undergo before shipment?
Every worm gear undergoes a rigorous quality control process, including more than 200 no-load test cycles before leaving the factory. Additionally, third-party testing institutions have verified key mechanical properties: tensile strength of 65 MPa, flexural modulus of 2800 MPa, and a dimensional change rate of less than 0.3% under humid conditions.
Q
What are the typical industries and use cases for these plastic worm gears?
Our precision plastic worm gears are widely used across multiple industries, including: smart home systems (intelligent curtain motors), medical devices (blood glucose meter miniature drives), industrial automation (robot joint reducers), and automotive engineering (tailgate lifting mechanisms). Their low noise output (below 35 dB) and high precision make them ideal for both consumer and industrial-grade applications.
