Full mold casting method, press die, upper mold, gray cast iron, FC250

Casting X - A casting method using digital technology for large and small rod castings, contact Tomo Iron Works for cost reduction!!

FMC casting creates foam models that are the same shape as the product using expanded polystyrene, and then produces the product by replacing the foam model with molten metal in a sand mold. This method makes it difficult for burrs to form and allows for the creation of complex and high-precision products. For small lots, cost reduction is possible compared to the wooden pattern method. Cost reduction is also possible with original (steel substitute) materials.

Stabilization of material components in wire spheroidization treatment.

Stabilization of material components in wire spheroidization treatment.

The automatic control of the feeder appropriately manages the input amount and input speed!

We would like to introduce the stabilization of material composition in our casting process known as "wire spheroidization treatment." When molten metal is received from the electric furnace into the ladle, the weight and temperature are input into the control computer, allowing for the subsequent addition of wire-shaped material while considering the target temperature and weight. At that time, the wire is mechanically controlled and fed from a dedicated feeder, which eliminates variations between production batches and human-induced variations, resulting in stable quality. [Wire Spheroidization Treatment] - Automatic control of the feeder allows for appropriate management of the amount and speed of addition. - Reduces the impact of human-induced variations. - Localized dust collection contributes to the improvement of the working environment. *For more details, please refer to the PDF document or feel free to contact us.
