　 1 Casting 　
砂込め作業PHOTO 脱型作業PHOTO
Packing sand 　 Removal of sand mold
A sand mold used for casting a cast product is formed by packing the sand mixture (sand mixed with resin and hardener). It is hardened over time. 　 The hardened sand mold is removed from the pattern.
　 　

被せ作業PHOTO 塗型作業PHOTO
Clamping 　 Protective coating
The upper and lower mold halves are securely clamped together to form a mold cavity (ready for pouring). 　 A protective coating is applied on the surface of the sand mold to protect against molten metal.
　
1Smelting
　 　 　
材料投入PHOTO 電気炉溶解PHOTO

Feeding material

　

Melting metal in electric furnace

The calculated quantity of material is fed to the electric furnace. 　 A control panel is used to control power input to the furnace to ensure optimum melting performance.
　 　

　 　

成分調整PHOTO
　 　

Controlling the content of molten metal
　 　 A CE meter is used for molten metal analysis. The content of molten metal is controlled within a specified range by adding the alloying element.
　
1 Pouring and Shakeout
　 　 　
出湯作業PHOTO 注湯作業PHOTO
Tapping 　 Pouring
The molten metal is tapped from the furnace into the ladle. 　 The molten metal is poured into a mold made of packed sand.

1 Finishing
　 　 　
ショット作業PHOTO 仕上作業PHOTO
Shot blasting 　 Trimming
Shot blasting removes scale and sand from the surface of castings after shakeout. The castings in the shot blasting machine are blast cleaned with a large amount of shot media. 　 The cleaned product is trimmed and finished by grinding all excess metal such as burrs, runners, feeder-heads and overflows.
　
　 　

塗装作業PHOTO
Inspection 　 Painting
　 　 The product is painted in the specified color. Careful finishing provides a very smooth surface.
