Forging Process Overview

Forging is a process of plastically forming metal by pressure. The core is to heat the blank and then use a die or forging hammer to stamp it. Relying on CNC equipment and die design capabilities, the company realizes full process control from blank forging to finishing, and cooperates with tools such as three-coordinate measuring machines to ensure accuracy and performance.

Application

Applicable to fields with high mechanical performance requirements: automotive transmission systems, hydraulic core components, agricultural machinery and industrial key components, etc. The company has passed ISO certification and customized processes to provide highly reliable and long-life metal solutions.

Forging Process Steps

Material Pretreatment
Precision Forming
Heat Treatment and Cooling
CNC Finishing
Full-process Quality Inspection

Material Pretreatment

According to the performance requirements of the parts, high-quality raw materials such as steel, aluminum alloy, and titanium alloy are selected, and the size and uniformity of the blank are ensured through cutting and heating pretreatment.
Precision Forming

After the blank is heated to the plastic temperature, the forging die developed by the company's own die design team is used, combined with the CNC four-spindle machining center and forging equipment to accurately control the punching force and deformation path to achieve one-time forming of complex structures.
Heat Treatment and Cooling

By controlling the cooling rate and heat treatment process (such as normalizing and quenching), the material grain structure is optimized, the mechanical strength and fatigue resistance are improved, and the performance requirements of high-stress components in the fields of automobiles and hydraulics are met.
CNC Finishing

After the forging blank is roughly processed by drilling machines, grinders and other equipment, the CNC vertical/horizontal machining center is used for high-precision dimensional correction and surface treatment to ensure that the tolerance range meets ISO standards.
Full-process Quality Inspection

Use three-coordinate measuring machines, projectors and other testing tools to fully verify the geometric dimensions, hardness and microstructure of finished products, combined with the ISO 9001/16949 quality system to ensure product reliability.

Through the above steps, the company realizes independent control of the entire process from blank forging to precision finished products, providing customers with high-efficiency and high-consistency customized forging solutions.

Our Forging Capabilities

Closed Die Forging

Process features: Forming in a closed cavity, no transverse flash, only a small amount of longitudinal burrs. High material utilization (up to 85%-95%), tolerance accuracy of ±0.6-0.8mm, suitable for complex precision parts such as gears and bearing rings.
Equipment adaptation: Double-acting hydraulic die frame, sliding clearance 0.08-0.20mm, die hardness HRC58-62, support friction press, hydraulic press and other equipment.
Hot Forging

Temperature range: Usually carried out above the recrystallization temperature (≥760℃), the steel is heated to about 1000℃ to reduce deformation resistance.
Advantages: Large and complex parts (such as ship crankshafts and automobile crankshafts) can be forged, but attention should be paid to the dimensional accuracy problems caused by the thickening of the oxide film.
Cold Forging

Temperature range: Carried out at room temperature (≤30℃), relying on phosphate film compound treatment technology and super-hard alloy molds.
Advantages: high dimensional accuracy (up to 0.1mm), good surface finish, suitable for batch production of small and medium-sized high-strength parts (such as automobile bolts).
Upset Forging

Process characteristics: local thickening of metal rods, and upsetting while heating through electric upsetting process, suitable for rod forgings such as valves.
Equipment: special electric upsetting machine, combined with cold-drawn materials and voltage stabilizing device, material utilization rate reaches 70%-80%.
