01 · COMPANY PROFILE

Who we are

Founded in 2010, Sunbond is a professional hot-work die steel forging company based in Tanbu Town, Huadu District, Guangzhou. We focus on the sale and re-forging of hot-work die steel. Our experienced R&D, quality-control and forging teams work closely with Guangdong Tianfumei Heat Treatment Co., Ltd. Every forging undergoes strict annealing, ultrasonic testing and metallographic inspection before shipment. Supported by 5,000-ton and 8,000-ton hydraulic presses, we can produce electroslag remelted steel to customer requirements. Our forged products serve automotive die-casting dies, wheel moulds, machinery components, extrusion dies and industrial tooling applications.
