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
Q1 What materials are used in your plastic worm gears?
Our plastic worm gears are manufactured using DuPont engineering-grade materials sourced from the United States. These materials offer exceptional mechanical strength, dimensional stability, and low friction properties. Optional conductive grade and anti-static grade variants are also available to meet the specific requirements of electronic applications.
Q2 What dimensional accuracy can you achieve?
Through precision injection molding processes, we achieve a dimensional accuracy of ±0.02mm. The helix angle error is controlled within ±0.5°, ensuring consistent and smooth gear meshing across all production batches.
Q3 How long can the worm gear operate without additional lubrication?
Thanks to our patented lubrication technology integrated into the gear design, our plastic worm gears can operate continuously for up to 10,000 hours without requiring additional lubrication. This significantly reduces maintenance costs and downtime in long-term applications.
Q4 What standard specifications are available in stock?
We maintain ready inventory for the three major mainstream specifications: M1.0, M1.5, and M2.0. For custom or special parameters outside these standard sizes, we support rapid mold opening within 30 days to accommodate your specific project requirements.
Q5 What quality testing is performed before shipment?
All products undergo more than 200 no-load test cycles before leaving the factory. In addition, third-party testing institutions have verified key performance metrics including a tensile strength of 65 MPa, a flexural modulus of 2800 MPa, and a dimensional change rate of less than 0.3% in humid environments.
Q6 In which industries are these worm gears commonly used?
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 applications (tailgate lifting mechanisms). Their low noise, lightweight, and self-lubricating properties make them suitable for a broad range of demanding environments.
