Cold forging
Cold forging is a forming process in which metal is processed without prior heating, below the recrystallization temperature. This process is frequently used to manufacture precise, high‑quality metal parts with enhanced strength and surface quality.
Properties and Advantages of Cold Forging
-
High dimensional accuracy: Cold forging enables production of parts with tight tolerances and high precision.
-
Improved surface quality: The surfaces of cold‑forged parts are smooth and show fewer irregularities.
-
Increased strength: The process increases material strength through work hardening.
-
Material efficiency: Less waste is generated compared to other forming processes.
-
Environmental friendliness: Because no high temperatures are required, energy consumption is lower and environmental impact is reduced.
Cold Forging Process
The cold forging process comprises several steps:
-
Raw material preparation: The metal is shaped into the desired initial form, often as bars or wires.
-
Forging: The raw material is pressed into the desired shape under high pressure. This can be performed using various techniques such as cold heading, cold extrusion, or cold rolling.
-
Post‑processing: Forged parts are cleaned and, where necessary, further processed to achieve the desired dimensions and surface quality.
Applications of Cold Forging
Cold forging is used in numerous fields:
-
Automotive industry: Manufacture of precision components such as screws, nuts, bolts and other fasteners.
-
Electronics: Production of components for electronic devices requiring high precision and strength.
-
Mechanical engineering: Fabrication of machine parts that must withstand high loads.
-
Medical technology: Production of medical instruments and implants with high dimensional accuracy and surface quality.
Safety and Environmental Considerations
Appropriate safety measures should be taken when cold forging to prevent injuries caused by high pressures and forces. These include wearing protective clothing, gloves and eye protection. Environmental considerations involve minimizing material waste and using eco‑friendly lubricants.
