Project Background
The hot press production line is a large-scale press production line independently researched, manufactured, and trial-produced by Si Chen Machinery to meet the needs of automobile engine casting factories to change castings to forgings.
Changing from castings to forgings not only reduces the amount of processing but also optimizes the product for lightweighting; moreover, forgings have a higher density than castings and are of better quality.
Project Introduction
Due to the thick thickness of the steel plate, it is difficult to form it in one time, and there are many variables in the hot extrusion process. Si Chen Machinery has developed special equipment that meets the extrusion process of different products and achieves automatic pressing and forming multiple times.
This equipment includes product conveying roller conveyors, medium-frequency local and overall heating, press equipment, and a cooling circulation system.

Project Value
1. Improved product quality by changing castings to forgings; 2. Precise processing of uncertain variables in the hot extrusion process through automated equipment;
3. Realization of a practical scheme for hot extrusion, secondary shaping, and simultaneous top ejection to avoid mold jamming.
