Frequently Asked Questions
Q1
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. Compared to standard plastics, DuPont materials offer significantly higher tensile strength (65 MPa), a flexural modulus of 2800 MPa, and excellent dimensional stability — with less than 0.3% dimensional change even in humid environments. This makes them far more reliable for precision mechanical applications.
Q2
How long can the plastic worm gears operate without lubrication?
Thanks to our patented lubrication technology integrated into the gear design, the plastic worm gears can operate continuously for up to 10,000 hours without requiring any additional lubrication. This dramatically reduces maintenance costs and downtime in automated systems.
Q3
What dimensional accuracy can be achieved, and how is it verified?
Our injection molding process achieves a dimensional accuracy of ±0.02mm. All products are verified by an independent third-party testing institution before delivery. In addition, every unit undergoes more than 200 no-load test cycles to ensure consistent quality and performance.
Q4
Do you offer anti-static or conductive grade materials for electronic applications?
Yes. We offer optional conductive grade and anti-static grade material variants specifically designed for electronic and sensitive device environments. These are ideal for applications such as blood glucose meters, precision medical instruments, and electronic assembly equipment where electrostatic discharge control is critical.
Q5
What standard specifications are available, and can custom sizes be ordered?
We maintain ready inventory for the three most popular specifications: M1.0, M1.5, and M2.0. For custom or non-standard parameters, we support rapid mold opening within 30 days, allowing you to obtain tailor-made solutions without lengthy lead times.
Q6
In which industries and applications are your plastic worm gears most commonly used?
Our 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 the automotive sector (tailgate lifting mechanisms). Their low noise (below 35 dB), high precision, and self-lubricating properties make them suitable for any application requiring quiet, reliable, and compact transmission.
