Improving on Cold Heading with Secondary Machining
Cold heading is the process of shaping semi-cold metal into a variety of different shapes, often used to make customized screws, bolts, and other metal fasteners. The cold heading process uses a large amount of force to transform the metal blank into the desired shape.
Many factories use cold heading to manufacture parts and pieces of all different sizes. However, there are fewer factories that continue modifying and improving on cold headed parts with secondary machining methods.
Secondary machining methods, like heat treating, rolling, or drilling can help maximize the effectiveness of cold headed parts. Cold heading provides many benefits, like reduced metal waste, and a short manufacturing time, but other issues are present with cold heading as well. In some cases, the metal tolerance of metal could be improved through secondary machining in some way.
Few factories take advantage of the multi-machining process to create the best metal parts possible. However, factories that do mix machining operations see improvements in the structure, quality, and strength of their products. Using a combination of machining methods, a factory can also expand the types of products that they offer to customers, creating unique parts and pieces that perform better than parts manufactured using one tooling method alone. This puts these factories in a unique position to offer one-of-a-kind products to customers and provide stronger, customized solutions that perform better than other products. This increases customer satisfaction and loyalty, and can cut down on product waste due to increased performance and strength.
