method of manufacturing stainless steel sinks with vats or colorees benches and sinks obtained

摘要

A process for manufacturing a sink of stainless steel having a tub member connected integrally or by assembly with a plate member forming a drain board. The process comprises forming the members of stainless steel, one of the members being coated with an adherent color layer of abrasion resistant material. The tub member is joined to the plate member along a rounded annular connection region to which the color layer extends and the annular connection region is tangentially ground all along its length to form a chamfer providing a precise connection between the color layer on the coated member with the bare surface of the other member. In the case where the color layer is applied after the members are connected together, a removable mask is placed in the areas which are not to be coated. When the tub member and plate member are assembled together from separate units, such assembly can be effected by electrically welding the members together at the bare contacting surfaces.
