Lost-in-process production line
The lost foam casting production line (lost foam production line) has reasonable process layout, advanced equipment, high degree of mechanization and automation, and has the world's advanced level in the early 1990 s. According to the process, the lost foam casting is divided into "white area" and "black area.
Lost foam casting is known as the casting method of the 21st century, its main advantages are:
1, the casting size precision is high, up to the national standard CT7 level or above.
2. The surface of the casting is smooth, and the surface roughness can reach more than Ra12.5.
3. Lost foam casting does not require a lower core and no parting surface. Flexible design can be adopted to produce castings with complex shapes, thin walls and porous grooves.
4. The casting processing volume is small and the weight is light, which can save a lot of processing hours.
5. The casting has no flash burr, easy sand cleaning, less cleaning time and good working environment.
6, the old sand can be recycled, less environmental pollution, known as the "green casting project".
7, less investment, short construction period, can quickly form the scale of production benefits.
