Frequently Asked Questions
❓
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 are selected for their superior mechanical strength, dimensional stability, and long-term durability, ensuring consistent performance across demanding applications.
❓
How long can the plastic worm gear operate without additional lubrication?
Thanks to our patented lubrication technology, the plastic worm gears can operate continuously for up to 10,000 hours without requiring any additional lubrication. This significantly reduces maintenance costs and downtime in automated systems.
❓
What dimensional accuracy can be achieved in your injection molding process?
Our injection molding process achieves a dimensional accuracy of ±0.02mm, ensuring tight tolerances for precision mechanical transmission applications. The helix angle error is controlled within ±0.5° for smooth and reliable meshing performance.
❓
Are custom specifications available, and what is the lead time?
Yes, we support custom parameters beyond our standard M1.0, M1.5, and M2.0 specifications. Custom orders can be fulfilled with a rapid mold opening lead time of approximately 30 days, allowing flexibility for unique application requirements.
❓
Do your products support anti-static or conductive grade options?
Yes. We offer optional conductive grade and anti-static grade material options for our plastic worm gears. These variants are specifically designed to meet the special requirements of sensitive electronic devices and ESD-controlled environments.
❓
What quality testing is performed before products are shipped?
All products undergo more than 200 no-load test cycles before leaving the factory. Additionally, mechanical properties including tensile strength (65MPa), flexural modulus (2800MPa), and dimensional stability in humid environments (change rate <0.3%) have been independently verified by third-party testing institutions.
