Frequently Asked Questions
Q
What material are your plastic worm gears made from, and why is it superior to standard plastics?
Our plastic worm gears are manufactured using DuPont engineering-grade materials sourced from the United States. These materials offer significantly higher tensile strength (65MPa), superior flexural modulus (2800MPa), and excellent dimensional stability in humid environments (less than 0.3% change rate) compared to standard engineering plastics, making them ideal for precision transmission applications.
Q
How long can the plastic worm gear operate without additional lubrication?
Thanks to our patented lubrication technology integrated into the gear design, the product can operate continuously for over 10,000 hours without requiring any additional lubrication, significantly reducing maintenance costs and downtime.
Q
What standard specifications are available, and can custom sizes be ordered?
We maintain ready inventory for the three mainstream specifications: M1.0, M1.5, and M2.0. For custom requirements, we support rapid mold opening within 30 days. Please contact our engineering team with your specific parameters for a tailored solution.
Q
Are there special material grades available for use in electronic or static-sensitive environments?
Yes. We offer optional conductive grade and anti-static grade material variants specifically designed to meet the requirements of electronic devices and environments where electrostatic discharge (ESD) control is critical.
Q
What quality testing does each product go through before shipment?
Every unit undergoes a rigorous quality control process, including more than 200 no-load operation tests prior to leaving the factory. In addition, product specifications have been independently verified by a third-party testing institution for tensile strength, flexural modulus, and dimensional stability.
Q
What are the key noise and precision performance metrics of these worm gears?
Our plastic worm gears achieve a dimensional accuracy of ±0.02mm and maintain a helix angle error within ±0.5° for smooth meshing. The surface roughness is Ra ≤ 0.8μm, which keeps operational noise below 35 decibels — suitable for noise-sensitive applications such as medical devices and smart home systems.
