MESSAGE

Message from the President

Turning a foundryman’s instinct into technology the next generation can use.

Founded in 1962 as a small workshop in Hamamatsu, Shiomi Alloy Foundry has grown together with the region’s transportation equipment industry.

Casting is delicate work: a slight change in temperature, humidity or sand condition changes the result. In a field that once relied heavily on veteran experience, we actively adopt CAE simulation and 3D measurement to record that instinct as data.

Inheriting craftsmanship and taking on the future — we will continue to answer every “Can you make a part like this?” with sincerity.

President & CEOKenichiro Shiomi
