Typical Application Scenarios
Frequently Asked Questions
Q
What material are your plastic worm gears made from, and why does it matter?
Our plastic worm gears are manufactured using DuPont engineering materials sourced from the United States. This ensures superior mechanical strength, dimensional stability, and resistance to wear and humidity — making them a reliable alternative to traditional metal components in demanding transmission applications.
Q
What level of dimensional accuracy can your worm gears achieve?
Through precision injection molding, our worm gears achieve a dimensional accuracy of ±0.02mm. The helix angle error is controlled within ±0.5°, and the surface roughness is Ra ≤ 0.8μm, ensuring smooth and quiet meshing performance.
Q
Do these gears require regular lubrication during operation?
No. Thanks to the patented lubrication technology integrated into our design, the gears can operate continuously for up to 10,000 hours without requiring additional lubrication. This greatly reduces maintenance costs and downtime in industrial and consumer applications.
Q
Are there material options suitable for use in electronic devices?
Yes. We offer optional conductive grade and anti-static grade material variants specifically designed to meet the special requirements of electronic devices, such as blood glucose meters and other precision instruments where electrostatic discharge must be controlled.
Q
What standard specifications are available, and can custom sizes be ordered?
Our current inventory covers three mainstream module specifications: M1.0, M1.5, and M2.0. For custom requirements, we support rapid mold opening within 30 days, allowing you to obtain tailored specifications without long lead times.
Q
How are the products tested before shipment?
Every product undergoes more than 200 no-load test cycles before leaving the factory. Additionally, our materials have been independently 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 of less than 0.3% under humid conditions.
