1. Casting brake surface blanks+： In the research and development of brake disc manufacturing, brake performance is the top priority, its material selection, wear resistance coefficient and thermal expansion coefficient directly determine the quality and safety of products. We use high carbon gray cast iron as the core material of brake body, this material selection has significant advantages In terms of material characteristics, high carbon gray cast iron is based on high carbon content, and the graphite in the interior is evenly distributed in the matrix structure. This unique microstructure endows the material with excellent shock absorption and noise reduction performance, which can effectively buffer the high-frequency vibration generated during braking, reduce harsh noise, and improve driving and riding comfort. In terms of wear resistance, high-carbon gray cast iron, thanks to its unique composition and microstructure, exhibits outstanding wear resistance. Professional tests have confirmed that its wear resistance coefficient is among the industry's best, capable of withstanding tens of thousands of high-intensity braking cycles. Even under harsh conditions such as frequent braking and heavy loads, it maintains stable friction performance, significantly extending the service life of the brake disc. In terms of thermal stability, the low coefficient of thermal expansion of high-carbon gray cast iron is a significant core advantage. In extreme conditions where continuous braking causes the brake surface temperature to spike (up to over 600℃), the material's dimensional change rate remains minimal, maintaining the precision of the disc geometry. This ensures the stability and reliability of the braking system, thereby preventing brake failure risks caused by thermal deformation at their root.

In this vibrant spring and summer season, our company organized a summer camp. On April 26, we took a good mood and went from the office to outdoor activities, and had a wonderful journey of "training empowerment + team cohesion"! This activity is mainly divided into two parts: indoor training and outdoor play.
