Product Q&A
Q:What is the difference between forging and casting?
A:
Forging transforms a solid from one shape to another through plastic forming, while casting transforms shapeless liquid metal into a solid shape. Forging is a solid-to-solid process, whereas casting is a solid-liquid-solid process.
Q:How to choose high-quality forgings?
A:
Quality inspection involves external observation for defects like cracks or scratches, and internal testing using specialized instruments to analyze chemical composition, structure, and mechanical properties such as tensile strength and hardness.
Q:What are the characteristics of the forging process for blank forgings?
A:
The process includes 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 are the available customization options?
A:
We offer flexible customization, minor customization, full customization from designs, and customization from samples, including shapes like round bars, squares, shafts, rings, and cylinders.
Q:What is the minimum order quantity?
A:
The minimum order quantity is 1 piece.
