Product Q&A

Q:What is the difference between forging and casting?

Forging transforms solid metal from one shape to another through plastic forming processes like extrusion or punching. Casting transforms liquid metal into a solid shape by pouring molten metal into a mold. Forging is a solid-to-solid process, while casting is a solid-liquid-solid process.

Q:How to choose high-quality forgings?

High-quality forgings are selected through external observation (checking dimensions, surface defects like cracks or wrinkles) and internal testing (analyzing chemical composition, mechanical properties, and using specialized instruments to detect internal fractures or shrinkage).

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

The forging process for circular forgings mainly consists of pier roughening, elongation, punching, and expanding. Free forging uses a horse screw to expand holes, while ring rolling uses rolling for this purpose.

Q:What materials and standards are used for these forgings?

We use 45# carbon structural steel (GB/T699-1999), with similar designations like S45C (JIS) and 1045 (AISI). The products meet GB/T19001-2016 and ISO9001:2015 standards.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 Pc. We support flexible customization, including minor and full customization from designs or samples.
