Solution
Hemisphere and Dome Forming
Stamped and welded metal hemispheres in stainless steel, carbon steel, brass and aluminium
Overview
Stamped and welded metal hemispheres in stainless steel, carbon steel, brass and aluminium
Stamping press hemispheres run from Φ20 mm to Φ700 mm, 0.6 mm to 3 mm thick. Welded and assembled hemispheres run from Φ200 mm to Φ3500 mm, 0.6 mm to 3 mm thick. Weld seams are finished so they are invisible in the polished surface.
Process Flow
From Requirement Analysis to Delivery
Every stage below has one owner and one output, so nothing is left to be resolved on site.
Size and Method Selection
Stamping for smaller diameters, spinning or welded assembly for larger domes.
Forming
Sheet is pressed, spun or assembled from segments depending on the diameter.
Edge Preparation
Rims are trimmed, levelled and prepared for the mounting detail you need.
Seam Finishing
Assembled domes have their seams ground and blended before polishing.
Surface
Mirror polish, mill finish, brush, electroplating, sandblasting, etching or silk printing.
Inspection
Reflection checked for uniformity, sharpness and distortion before packing.

FAQ
Hemisphere and Dome Forming FAQ
What do you need from me to start?
A size, a grade, a finish and a destination. A drawing, a photograph or a small sample is enough for our 3D drawing team to develop the panels.
Do you quote one off pieces?
Yes. Commissions of one are normal here, and the same route also covers repeat batches.
Can I change the specification after quoting?
Yes, before production starts. Diameter, grade, wall thickness, finish and mounting can all be revised, and we requote against the change.
How is the finished piece protected in transit?
Pieces are crated for the freight route chosen. Customs clearance paperwork is handled by the carrier and we assist where extra documentation is required.
