Frequently Asked Questions
Q
What material are your plastic worm gears made from, and why is it superior?
Our plastic worm gears are manufactured using DuPont engineering materials sourced from the United States. These materials offer exceptional mechanical strength, low friction coefficients, and excellent dimensional stability. Compared to standard plastics, DuPont materials provide a tensile strength of 65MPa and a flexural modulus of 2800MPa, making them a reliable replacement for metal components in many transmission applications.
Q
How long can these worm gears operate without lubrication?
Thanks to our patented lubrication technology incorporated into the material and design, these plastic worm gears can operate continuously for up to 10,000 hours without the need for additional lubrication. This significantly reduces maintenance costs and downtime in automated systems.
Q
What standard specifications are available in your current inventory?
We currently maintain inventory for three mainstream specifications: M1.0, M1.5, and M2.0. For non-standard or custom specifications, we support rapid mold opening within 30 days to meet your project's specific requirements.
Q
Are these gears suitable for use in humid or moisture-exposed environments?
Yes. Third-party testing has confirmed that the dimensional change rate of our plastic worm gears is less than 0.3% even in high-humidity environments. This ensures consistent performance and precise meshing in applications exposed to moisture, such as outdoor automation or medical devices.
Q
Do you offer anti-static or conductive grade materials for sensitive electronic applications?
Absolutely. We offer optional conductive grade and anti-static grade material variants specifically designed for use in electronic devices and ESD-sensitive environments. These are ideal for applications such as blood glucose meters, semiconductor equipment, and precision medical instruments.
Q
What quality control processes are in place before shipment?
Every plastic worm gear undergoes a minimum of 200 no-load test cycles before leaving the factory. In addition, each batch is verified for dimensional accuracy (±0.02mm), helix angle error (within ±0.5°), and surface roughness (Ra ≤ 0.8μm) to ensure consistently high quality and quiet operation below 35 decibels.
