Main processing methods
1, scroll
The metal blank passes through the gap (various shapes) between a pair of rotating rollers. Due to the compression of the rollers, the cross section of the material decreases and the length increases. This is the most commonly used production method for producing steel, mainly used for producing profiles, plates and pipes. Cold rolling and hot rolling.
Step 2 cast
A pressure processing method that uses the reciprocating impact force of forging hammer or the pressure of press to change the blank into the shape and size we need. Generally divided into free forging and die forging, it is often used to produce materials with large cross-sectional dimensions such as large profiles and cogging.
Step 3 pull
Processing method of stretch rolling metal blank (mold, pipeline, product, etc.). ) reducing the cross section and increasing the length through the die hole is mostly used for cold working.
Step 4 squeeze
The processing method of putting the metal into a closed extrusion box and applying pressure at one end to extrude the metal from the specified die hole to obtain the finished product with the same shape and size, which is mostly used to produce non-ferrous metal materials.
