Production Process

Raw material selection and chemical composition control

• We strictly select high-quality alloy steel from well-known steel mills at home and abroad, and the chemical composition is tested by a spectrometer to ensure that the content of elements such as C, Cr, and Mo is accurate and stable.

High-temperature forging and preliminary shaping

• Forging at a high temperature of more than 1,200 ℃ makes the internal grains refined and the structure dense. After preliminary shaping, it is put into storage for inspection.

Multi-stage heat treatment strengthening

• Normalizing: 850–900 ℃ uniform heating to refine the metal structure.
• Quenching: Rapid cooling under oil cooling medium, the hardness is increased to HRC 48–52.
• Double tempering: 580–620 ℃ for more than 2 hours to eliminate internal stress and improve toughness.

CNC precision machining and online measurement

• Imported five-axis linkage CNC machine tools are used, and the machining tolerance is controlled at ±0.02 mm. Critical dimensions are tested online using a three-coordinate measuring machine to ensure that every piece leaves the factory with precision.
