Overview
Marumae is headquartered in Izumi, Kagoshima. It machines, welds and surface-treats vacuum parts for semiconductor and flat-panel display equipment, including large and high-precision parts such as vacuum chambers and electrodes.
Vacuum chambers and electrodes are large, precisely machined parts made from aluminium or stainless steel and then surface-treated. Equipment makers outsource much of this work, so parts makers in Japan move with equipment orders and must keep up with tighter flatness and cleanliness requirements.
Business: Precision-machined vacuum parts for equipment
Why it matters
- Equipment makers outsource much of their precision machining, so parts makers' capacity rises and falls with equipment demand.
- Kagoshima is part of the Kyushu region, where semiconductor investment has grown around Kumamoto.
