Product Q&A

Q:What is the difference between forging and casting?

Forging transforms solid metal into another shape through plastic forming (hot or cold), while casting transforms liquid metal into a solid shape by pouring it into a mold. Forging is a solid-to-solid process, whereas casting is a solid-liquid-solid process.

Q:How to choose high-quality forgings?

Quality is verified through external observation (checking for cracks, wrinkles, bubbles, and dimensional accuracy) and internal testing (analyzing chemical composition, microstructure, tensile strength, hardness, and ductility using specialized instruments).

Q:What are the characteristics of the forging process for blank forgings?

The process includes pier roughening, elongation, punching, and expanding. Free forging uses a horse screw to expand holes, while ring rolling uses rolling to expand holes.

Q:What materials are available for these forged rings?

We provide various materials including C45, 42CrMo, chromium-nickel-molybdenum steel, bonded steel, carbon steel, stainless steel, spring steel, and bearing steel.

Q:What are the customization options available?

We offer flexible customization including minor customization, full customization, customization from designs, and customization from samples.
