COLD FORGING

WHAT IS COLD EXTRUSION?

Cold extrusion can be defined as forcing unheated metal to flow through a shape forming die. It is a method of shaping metal by plastically deforming it under compression at room temperature while the metal is under a die cavity formed by the tools. It is a chipless forming technology.

Cold forming products to near net shape maximises material usage producing virtually no wastage. The process of cold extrusion is ideal for fast volume production at least cost. On this score it is unrivalled.Cold Extrusion is a modern method of forming parts, superior in many respects to other technologies.

ADVANTAGES OF COLD EXTRUSION PROCESS:

•Saves material sometimes over 50%.
•Avoids machining to a great extent.
•Ideal for large volume faster production.
•Work hardens and strengthens cheaper material to required specification eliminating need for heat-treatment.
•Good surface finish and close tolerances are achievable.
•Uniform, uninterrupted grain flow develops naturally during the forming process, giving extruded parts higher strength.
