Secondary stamping operations can be used to produce very small quantities of simple parts inexpensively. They can also be used to produce small to moderate quantities of parts that could have been produced with a progressive die, thus avoiding the cost of the large die. Secondary operations are the only option to produce parts whose geometry is suited neither to a progressive die, nor a compound die (for an example of such a piece, see case study 7). Finally, secondary stamping operations are frequently the most cost-effective method of completing a job consisting of a family of parts (for an example of such a piece, see case study 5).
The most common secondary machining operation is tapping. While there are dies capable of performing crude tapping within the die, we've found these methods to be unreliable. We use two floating armature tapping machines and a Procunier multiple-head tapping machine for our production tapping requirements.
We offer several methods of deburring and surface conditioning, including belt grinding, buffing, vibratory tumbling, and barrel tumbling in a variety of media, wet and dry, and bead-blasting. Other finishing requirements that we can provide in a turnkey role include plating, anodizing, heat treating, and passivating.
