Core Advantages
In the field of mechanical transmission, plastic worm gears are gradually replacing traditional metal components. Our products, made with DuPont materials from the United States, achieve dimensional accuracy of ±0.02mm through injection molding. The unique double-ended thread design enhances the load capacity by 40%, and combined with the patented-lubrication technology, it can operate continuously for 10,000 hours without additional lubrication.

Frequently Asked Questions
Q
What material are your plastic worm gears made from, and why is it significant?
A
Our plastic worm gears are manufactured using authentic DuPont engineering-grade materials sourced from the United States. DuPont materials are renowned for their superior mechanical strength, chemical resistance, and dimensional stability, making them ideal for precision transmission applications that demand long-term reliability.
Q
How long can the plastic worm gear operate without lubrication?
A
Thanks to our patented self-lubrication technology, the plastic worm gear can operate continuously for up to 10,000 hours without requiring additional lubrication. This significantly reduces maintenance costs and downtime in industrial and consumer applications.
Q
What standard specifications are available, and can custom sizes be produced?
A
We maintain ready stock for three mainstream specifications: M1.0, M1.5, and M2.0. For custom requirements, we support rapid mold development with a turnaround of approximately 30 days, allowing flexible production for special parameters and unique application needs.
Q
Are the plastic worm gears suitable for use in electronic or sensitive environments?
A
Yes. We offer optional conductive grade and anti-static grade material variants specifically designed to meet the requirements of electronic devices, medical equipment, and other environments where electrostatic discharge control is critical.
Q
What quality testing does each product undergo before shipment?
A
Every plastic worm gear undergoes a minimum of 200 no-load test cycles before leaving the factory. In addition, mechanical properties are verified by a third-party testing institution, confirming a tensile strength of 65 MPa, a flexural modulus of 2800 MPa, and a dimensional change rate below 0.3% in humid conditions.
Q
What are the typical noise levels produced during operation?
A
Our plastic worm gears are engineered for quiet operation. With a surface roughness of Ra ≤ 0.8μm and helix angle error controlled within ±0.5°, operational noise is reduced to below 35 decibels — making them highly suitable for noise-sensitive applications such as smart home devices and medical instruments.
