The conical frustum — a truncated cone wider at the top and narrowing toward the base — is one of the most geometrically demanding containers to heat effectively. The continuously changing circumference means a standard blanket will never fit correctly, leaving gaps, pressure points and unheated zones that directly impact material flow and process stability. Our custom heating blankets are engineered to follow the exact taper of your conical frustum — from the top diameter down to the outlet — ensuring consistent, gap-free heat distribution across the entire surface.
