Cold Extrusion Parts

The function of cold extrusion parts can be understood as a metal blank being placed in a cold extrusion chamber at room temperature. At room temperature, a punch attached to our press applies pressure to the blank, causing the metal of the raw material to plastically deform, thus creating the resulting shape of the part.

Cold extrusion is a processing method that places a metal blank in a cold extrusion mold cavity, applies pressure to the blank through a fixed punch on a press at room temperature, and causes plastic deformation of the metal blank to produce parts. China is capable of cold extrusion of metals such as lead, tin, aluminum, copper, zinc and their alloys, low carbon steel, medium carbon steel, tool steel, low alloy steel and stainless steel, and even bearing steel, high carbon and high aluminum alloy tool steel, high-speed steel, etc. with a certain amount of deformation. In terms of extrusion equipment, China has the ability to design and manufacture various tonnage extrusion presses. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed high-energy equipment have also been successfully used for cold extrusion production.

Cold extrusion parts produced by cold extrusion can save a lot of steel and non-ferrous metal materials.


What should be considered in cold extrusion parts?


In order to ensure that the cold extrusion process is technically and economically reasonable and feasible, we generally use the following indicators to measure:

1. For larger extruded parts, cold extrusion is more difficult to apply.

2. The more complex the shape of the extruded part and the greater the degree of deformation, the more cold extrusion is required.

3. The accuracy and surface roughness of extruded parts are limited. Increasing the trimming process will improve the accuracy of extruded parts.

4. The extruded material directly affects the extrusion difficulty and allowable deformation.

5. The cost of extruded parts generally includes material cost, material preparation cost, tool and mold manufacturing cost, cold extrusion cost and subsequent processing cost.

6. Larger extruded parts can reduce the overall cost.


Through a comprehensive analysis of the above indicators, you can clearly choose the best treatment plan. Details and advice on the best processing plan are as follows: It uses as few extrusion processes and intermediate annealing times as possible and meets the technical requirements for extruded parts on the market through the lowest material consumption, highest tool life and production efficiency. The design of the cold extrusion process is a key task in the planning of the cold extrusion process.
