Frequently Asked Questions
Q
What material are these plastic worm gears made from, and why is it significant?
Our plastic worm gears are manufactured using DuPont engineering plastics sourced from the United States. DuPont materials are renowned for their superior mechanical strength, dimensional stability, and low friction properties, making them ideal for precision transmission applications. This material choice ensures consistent performance, longevity, and reliability across a wide range of operating conditions.
Q
What dimensional accuracy can I expect from these worm gears?
Our injection molding process achieves a dimensional accuracy of ±0.02mm, with a helix angle error controlled within ±0.5°. This high level of precision ensures smooth and consistent meshing, minimizes backlash, and supports reliable performance in demanding mechanical assemblies.
Q
How long can the worm gears operate without lubrication?
Thanks to our patented self-lubrication technology and the inherent low-friction properties of the DuPont material, these worm gears can operate continuously for up to 10,000 hours without requiring additional lubrication. This significantly reduces maintenance costs and downtime, making them especially suitable for sealed or hard-to-access applications.
Q
Are these worm gears suitable for use in humid or wet environments?
Yes. Third-party testing has confirmed that the dimensional change rate in humid environments is less than 0.3%. Combined with a tensile strength of 65 MPa and a flexural modulus of 2800 MPa, these gears maintain excellent structural integrity and dimensional stability even under challenging moisture conditions.
Q
What standard specifications are available, and can custom sizes be ordered?
We maintain ready stock for the three mainstream specifications: M1.0, M1.5, and M2.0. For custom requirements beyond these standard sizes, we support rapid mold opening with a lead time of approximately 30 days. Please contact our technical team with your specific parameters for a tailored solution.
Q
What quality control measures are applied before the products are shipped?
Every worm gear undergoes more than 200 no-load test cycles prior to shipment to ensure consistent performance and dimensional conformity. In addition, key mechanical properties including tensile strength, flexural modulus, and noise levels have been independently verified by a third-party testing institution, giving you full confidence in the quality of every component you receive.
