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 press forming is used to fabricate head plates that are very thick or made of special materials.
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.
Hot spinning is used to fabricate head plates with inner diameters ranging from 600-7,000mm and plate thickness of up to 120 mm.
Segment press forming is used to fabricate very large, specially shaped head plates, which cannot be fabricated via pressing and spinning.Parts are fastened togerther by welding after dishing.
This is a method for shaping plates with air or liquid pressure, without molds, and applied to shaping large, thin head plates.
The advantage of this method is that the plate’s surface cannot be scratched during processing, because the material is not in contact with a mold. For this reason, it's ideal for food, beverage and pharmaceutical needs.
