What is the difference between metal stamping and extrusion?

Stamping parts processing plants, processing metal stamping parts, stainless steel stamping parts, carbon steel drawing, different processes have different process characteristics. Today, let’s take a look at the difference between metal stamping and extrusion? 1. Hardware stamping is under the pressure of a punching machine, the product shape changes, and the material thickness basically does not change. Hardware stamping is the use of punches and molds to deform or break stainless steel, iron, aluminum, copper and other plates and special-shaped materials to achieve A process of a certain shape and size. Metal stamping is sometimes called sheet forming, but there are some differences. The so-called sheet forming refers to the use of sheet materials, thin-walled tubes, thin profiles, etc. as raw materials for stamping parts. The forming method of plastic working is collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered. 2. Extrusion is to make the material flow under the pressure of the punch or forging bed and the die, and the thickness and structure of the material are changed to meet the needs of the design. The direction of the material flow and the force of the forging bed is divided into front extrusion, rear backlog and Compound extrusion. Stainless steel extrusion uses forging oil, and different grades of stainless steel use forging oil differently. It needs to be verified to reduce friction coefficient and improve material fluidity; extrusion, especially cold extrusion, has high material utilization and material structure The mechanical properties are improved, the operation is simple, and the productivity is high. It can produce long rods, deep holes, thin-walled, and special-shaped cross-section parts. It is an important cutting process. Extrusion is mainly used for the forming of metals, but also for the forming of non-metals such as plastics, rubber, graphite and clay blanks; extrusion, according to the temperature of the blanks, can be divided into hot extrusion, cold extrusion and warm extrusion. The extrusion when the metal billet is above the recrystallization temperature (see plastic deformation) is hot extrusion; the extrusion at room temperature is cold extrusion; the extrusion at room temperature but does not exceed the recrystallization temperature is warm extrusion. According to the plastic flow direction of the blank, extrusion can be further divided into: 1. The flow direction is the same as the pressurizing direction is forward extrusion; 2. The flow direction is opposite to the pressurizing direction is reverse extrusion; 3. The blank is forward and reverse Flowing in both directions is called compound extrusion.
