Z18 Series Automatic Cold Header

Cold Heading Machine uses high speed automated "cold-headers” or "part formers” to transform a wire into an intricately shaped part with tight and repetitive tolerances. The process is volume specific and uses dies and punches to convert a specific "slug” or blank of a given volume into a finished intricately shaped part of the exact same volume. Cold Heading Machinery is specially designed for the mass production of the fasteners, especially screws and bolts.
Based on the thread length, diameter and forging force, our Cold Heading Machinery can be further classified into Z25 Series, Z12 Series, Z18 Series, Z41 Series and Z47\Z46 Series.
