Extrusion: Under the action of three-way uneven compressive stress, the blank is extruded from the orifice or gap of the die to reduce the cross-sectional area and increase the length. The processing method to become the required product is called extrusion. This processing of the blank is called Extrusion.
Process flow:
Preparation before extrusion→heating of casting rod→extrusion→stretching and twisting straightening→saw cutting (fixed-length)→sampling inspection→artificial aging→packing and warehousing
advantage:
1. Wide production range, many product specifications and varieties;
2. Large production flexibility, suitable for small batch production;
3. The product has high dimensional accuracy and good surface quality;
4. The equipment investment is small, the plant area is small, and it is easy to realize automatic production.
shortcoming:
1. Large loss of geometric waste;
2. Uneven metal flow;
3. Low extrusion speed and long auxiliary time;
4. Large tool wear and high cost.
Scope of production: Mainly used for manufacturing long rods, deep holes, thin-walled, and special-shaped cross-section parts.
