Arc-Shaped Teeth: Featuring precise arc-shaped teeth, high-strength tension lines, remarkable anti-extension capabilities, and a wear-resistant nylon surface layer for optimal tooth protection. Crafted from polybutadiene rubber, our belts offer low noise and impeccable precision, making them ideal for intricate transmissions. Genuine imports stand as the pinnacle of timing belt quality, though domestically manufactured alternatives, like those by Sanmin Gears, provide cost-effective options.

Distinguishing GT from S2M:

1.Tooth Design: GT employs precise arc-shaped teeth, while S2M boasts flat tooth tips.
2.Origins: GT is the domain of GATES, whereas various brands produce S2M belts.
3.Interchangeability: GT belts can substitute S2M, but the reverse is not advised.
Manufacturing and Formation Process:
The synchronous belt production process features two primary methods. One involves shorter mold-based shaping, utilizing flat vulcanizing machines. While this method offers simplicity and low investment, its drawbacks include unstable product quality, high material consumption, elevated production costs, low efficiency, and substantial labor intensity. The second, more popular approach entails continuous tension molding using vulcanization and rubber-coated sleeves, followed by grinding post-vulcanization and branding before cutting. This method uses flexible, unpartitioned rubber sleeves of varying lengths for external mold pressure vulcanization, addressing the shortcomings of the former method and representing an advanced production technique.


1.Semi-Finished Preparation:
Following the prescribed process, ingredients are mixed and various cavity materials are pressed to specifications. Pressed sheets should be uniform and bubble-free. Nylon-coated fabric is dried, cut, and sewn into cylindrical shapes. A specialized demolding agent is applied to the awaiting mold. Vulcanization cavities are pre-fabricated. Layers of predetermined thickness are wound onto vulcanization cavities sprayed with demolding agent. After wrapping with a water-soaked cloth, they are placed into a vulcanization tank for curing. Post-curing, they are demolded and readied.

Prepared nylon fabric sleeves are suspended on corresponding molds, mounted on the molding machine. Glass fiber ropes are wound with specified pitch and tension, followed by layering with a set thickness of body rubber sheets.

Unvulcanized belt sleeves are hung within the vulcanization tank, sealed, and subjected to external steam pressure of 0.3~0.6 MPa. After a period of pressure maintenance, saturated steam is introduced into the inner steam chamber to accelerate vulcanization.

Post-vulcanization, the belt sleeves are hung in a cooling tank for gradual cooling.

Cooled belts are mounted onto a grinder, ground to specified dimensions, and then removed.

Ground belt sleeves are suspended on a demolding machine. Adequate demolding claws are selected and pressure applied. The bottom plunger is activated, pushing the molds out of the belt sleeves. Molds are placed in a storage area for later use.

7.Trademark Printing:

An appropriately sized expansion drum is chosen for the cutting machine. After being wound with layers of non-sulfurized rubber sheets, the belt is ground to the desired outer diameter using a fine abrasive wheel. Once tightly fitted on a belt sleeve, it is cut.
