Frequently Asked Questions
Q
What materials are used to manufacture your plastic worm gears?
Our plastic worm gears are manufactured using DuPont engineering-grade materials sourced from the United States. These materials offer superior mechanical strength, dimensional stability, and long-term durability. Optional conductive grade and anti-static grade variants are also available to meet the specific requirements of electronic device 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 surface roughness is maintained at Ra ≤ 0.8μm, ensuring smooth meshing and quiet operation below 35 decibels.
Q
Do your plastic worm gears require regular lubrication during operation?
No. Thanks to our patented lubrication technology integrated into the material and design, our plastic worm gears can operate continuously for up to 10,000 hours without any additional lubrication. This significantly reduces maintenance costs and downtime in long-term applications.
Q
What standard specifications are available in stock, and can custom sizes be ordered?
We maintain ready inventory for the three mainstream specifications: M1.0, M1.5, and M2.0. For custom requirements, we support rapid mold opening within 30 days. All products — standard or custom — undergo more than 200 no-load tests before shipment to ensure consistent quality.
Q
How do your plastic worm gears perform in humid or demanding environments?
Our products have been independently verified by a third-party testing institution. In humid environments, the dimensional change rate is less than 0.3%. The tensile strength is 65 MPa and the flexural modulus reaches 2800 MPa, demonstrating excellent structural integrity under challenging operating conditions.
Q
What are the typical industries and applications for your plastic worm gears?
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 automotive applications (tailgate lifting mechanisms). Their lightweight design, low noise, and high precision make them ideal for compact and precision-critical systems.
