Galvanoforming

Galvanoforming or electroforming produces parts by electroplating a thick layer of metal on a negative or positive form. The form can be made from wax, tin, aluminum, silicon rubber, stainless steel etc. If the form is not electrically conductive, it can be treated with conductive paint. BOEHM utilises its own procedure to achieve conductivity without building up the forms surface. The form is electroplated until the desired thickness of the layer is achieved. Common are copper-, nickel- and silverlayers. Form and layer are separated by dissolving the form (aluminum, tin, wax) or separating form and layer mechanically (silicon, stainless steel).

Galvanoformed parts have close tolerances and exactly replicated surfaces. Complex inside surfaces can be produced to close tolerances. The process is especially useful for thin walled parts.
