Our Capabilities

As China’s foremost Manufacturer of high-performance die-casting machine parts, Yulong distinguishes itself through a steadfast commitment to quality, innovation, and cost-efficiency. Serving over 300 die-casting factories, we bring industry-leading expertise to ensure each client receives optimal solutions tailored to their needs.

Advanced Heat Treatment: Key to Premium Die-Casting Parts

We use state-of-the-art equipment from the esteemed German brand, IPSEN in our heat treatment process. This includes a vacuum quenching furnace, a multi-use quenching furnace, and a vacuum nitriding furnace, all providing excellent temperature uniformity and control. This ensures a consistent, high-quality output for our products.

Our unique nitriding process further enhances the surface hardness of our products to ≥ HV900 and nitriding depth to ≥ 0.3mm, significantly increasing their wear and corrosion resistance. 

This robust heat treatment process, combined with our strict quality control, enables us to deliver die-casting machine parts with exceptional durability, efficiency, and overall performance.
