Synchronous Pulley

As a specialist insynchronous pulley, Guangzhou Guangming Metal Products Co.,Ltd over two hundred different specifications and materials of synchronous pulley components.Manufactured from wear-resistant materials and processed using a standard sintering process, the product achieves a density of 6.8 g/cm³, meeting the requirements of most general industrial applications. After sintering, the product exhibits the natural metallic color of iron-based materials, and the surface can be treated with rust-preventive oil. The tooth profile accuracy is controlled within a reasonable range to ensure basic transmission precision requirements. This economical design is particularly suitable for large-volume purchases by OEM customers, providing a reliable solution in cost-sensitive applications.

Product Feature And Application

The core advantages of producing synchronous pulley using powder metallurgy technology are near-net-shape forming, integrated pulley tooth profile and hub structure, and significant advantages in cost, efficiency, and consistency under large-scale production.

(1)Near-net shape forming, with the tooth profile/hub integrally pressed, significantly reduces subsequent machining.  Both iron-based and stainless steel powders can be adapted for forming by adjusting the pressing parameters, completely avoiding the difficulties of machining complex tooth profiles.

(2)Material utilization rate exceeds 95%, resulting in significant savings in raw material costs.Iron-based and stainless steel raw materials have a high unit price, and traditional machining or forging processes result in 30% to 60% material loss; powder metallurgy uses quantitative powder filling and pressing, resulting in only a very small amount of powder waste. The material cost savings for stainless steel pulleys are even more pronounced than for iron-based ones, and the cost advantage in raw materials will be further amplified under large-scale production.
