Product Q&A

Q:What is the difference between forging and casting?

Forging transforms solid metal from one shape to another through plastic deformation, while casting transforms liquid metal into a solid shape by pouring it into a mold. Forging improves mechanical properties, whereas casting focuses on melting and pouring processes.

Q:How to choose high-quality forgings?

High-quality forgings are selected by checking external dimensions and surface defects (cracks, wrinkles) and performing internal testing for chemical composition, mechanical properties, and structural integrity 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 for expanding holes, while ring rolling uses rolling methods for the same purpose.

Q:What materials are used for these spindle parts?

The parts are made from structural carbon steel, specifically 45# steel (GB standard), which corresponds to S45C (JIS) and 1045 (AISI). It features good cutting performance and high hardness after heat treatment.

Q:Is customization available for sizes and shapes?

Yes, sizes are customized. Available shapes include Round Bar, Square, Shaft, Ring, and Cylinder. Delivery surfaces can be Black, Rough Machining Bright, or Fine Machining Bright.
