Frequently Asked Questions
What makes Sponge Composite flat belts better than V-belts?
Flat belts offer up to 98% transmission efficiency compared to 93 to 95% for V-belts. They also produce less vibration, run quieter, and allow smaller pulley diameters, reducing overall system cost and size.
Can you produce custom sizes and profiles?
Yes. We manufacture flat belts from 10mm to 600mm width, 0.8mm to 8mm thickness, in any length. Custom surface patterns, edge profiles, and material formulations are available for OEM requirements.
What is your typical lead time and MOQ?
Standard belts ship within 7 to 12 working days. For custom specifications, lead time is 15 to 20 days. MOQ starts at 10 pieces for standard belts and 50 pieces for custom orders.
