With cold press forming, head plates can be formed with inner diameters ranging from 200-3,200 mm (50 mm pitch up to 2,000 mm, and 100 mm pitch for above 2,000 mm), and with plate thickness of up to 28 mm using the fully-automated press we developed exclusively for head plates. Our cold press forming technology meets JIS standards for head plates, and contributes to their reliable quality as well as boosting productivity.

Hot spinning is used to fabricate head plates with inner diameters ranging from 600-7,000 mm and plate thickness of up to 80 mm.

Spinning is used to fabricate medium-sized (non-standard) head plates and those of large diameters. Using cold spinning,head plates can be formed with inner diameters ranging from 400-8,000 mm and plate thickness of up to 26 mm.Head plates with inner diameters of up to 12,000 mm can be fabricated if they are thin and the knuckle radius is short.
