Custom Metal Forging Process in Metal Forming Company China

Forging shapes metals through plastic deformation (hot forging/warm forging/cold forging), endowing them with high strength, toughness, fatigue resistance, and a dense microstructure, suitable for critical load-bearing components. The materials include carbon steel, alloy steel, titanium alloy, etc., and the processes include free forging, die forging, and precision forging. Core products such as automotive crankshafts, aviation engine blades, oil and gas valves, and heavy-duty gears have high load-bearing and impact resistance characteristics. Advantages: Eliminating casting defects and improving mechanical performance; Batch production costs are controllable and suitable for harsh working conditions (high temperature/high pressure). Quality control relies on non-destructive testing (UT/RT) and metallographic analysis, which are one of the core processes in high-end equipment manufacturing.

The existing equipment can meet the needs of various types of free forging and ring forging products, and has factory certification certificates from 8 major ship class societies worldwide, API20A qualification certificates from the United States, API6A qualification certificates, APIQ1 system certificates, TPG NDT certification certificates, TPG heat treatment certification certificates, EU PED certification certificates, etc.

The materials we can produce are:

Carbon Steel: A105N, LF2, A694 F60, F65 etc.

Austenitic SS: ASTM A182 F316/F316L F304/F304L etc.

Duplex SS: ASTM F51, F60, F53, F55 etc.

The weight of forgings can reach 40-650kg; Maximum diameter 1600mm

How to Improve the Durability of CNC Machine Tool Parts Through Forging

The core mechanism for improving the durability of CNC machine tool parts through forging can be divided into the following four aspects:

Grain refinement enhances fatigue resistance

Forging densifies metal grains and eliminates casting defects such as porosity and shrinkage through hot deformation, improving the uniformity of the microstructure of the parts, increasing fatigue strength by 30% -50%, and extending the high-frequency impact resistance life of key components such as gears and spindles.

Directional fiber streamline enhances load-bearing capacity

Forging continuously distributes metal flow lines along the direction of force on the part, forming a fiber network similar to a "skeleton". Under dynamic loads, the deformation resistance is more than twice that of machined parts, and the wear rate of moving parts such as rails and screws is reduced by 40%.

Stress concentration point elimination

Precision forging can form complex curved surfaces as a whole, avoiding weak areas caused by welding/assembly, making the stress distribution of structures such as bearing seats and knife towers more uniform, and reducing the risk of crack initiation by 60%.

High temperature stability optimization

After temperature controlled forging, the heat resistance and creep resistance of forged aluminum alloy/alloy steel are improved. The dimensional stability of components such as the spindle box is enhanced under continuous cutting heat load, and the precision maintenance cycle is extended by 3-5 times.

The Importance of Forging in the Production of High-strength Components

Material performance improvement

Forging refines metal grains through high-temperature plastic deformation, eliminates internal defects (pores, shrinkage porosity), significantly improves material density, and increases tensile strength, toughness, and fatigue life by 30% -50%.

Optimization of streamline structure

The metal streamline is distributed along the contour of the component in a directional manner, forming a continuous fiber structure, which increases the load-bearing capacity of the machined part by 2-3 times, especially under alternating stress conditions.

Lightweight design support

The forging process can accurately control the distribution of materials and achieve complex structures such as thin-walled and hollow structures while ensuring strength, reducing weight by 15% -25% compared to traditional castings.

Full cycle cost advantage

Although the cost of molds is relatively high, extending the service life of forgings can reduce maintenance frequency, and the comprehensive usage cost is reduced by more than 40% compared to welding/casting structures, making it particularly suitable for high-end fields such as aviation and energy.
