Custom moulding in the USA refers to the specialized process of creating tailored architectural or industrial mouldings to meet specific design, size, or material requirements. It is widely used in residential, commercial, and manufacturing sectors to achieve precise fits and aesthetic details. The process typically involves advanced fabrication techniques such as CNC machining, casting, or extrusion, depending on the material—wood, plastic, or metal. Custom moulding is often required in restoration projects, new construction, or product development where standard mouldings do not suffice. Its applications range from trim and casing in interiors to complex parts in industrial equipment and packaging solutions.
