One of Accurate Forming’s value added operations is the ability to form threads on the external or internal surfaces of the deep drawn product. Thread forming is defined as a process of reshaping the surface of material such as a round tube or bar into graduated thread form.
How threads are formed in the deep drawn process
The deep drawn process accomplishes this by rolling the threads into the surface of the part in a similar manner as other deep drawn product geometries are created. By comparison, typical threading operations involve cutting the threads into the surface of the material, thereby creating more wasted material per part.
Why rolled threads are often better than other methods
Forming threads by use of press and roller machines also creates a thread that is stronger than those produced by cutting operations by creating surfaces that are cold worked by pressure. This added strength provides longer life, resistance to corrosion, and increased wear resistance. Comparatively, typical thread cutting operations create thread surfaces that are coarse, prone to corrosion, and can cause localized weakness in the finished part.
Why Accurate Forming
When deciding on thread forming using the rolled thread method, considerations should be taken regarding the outside diameter and the length of the part. As always, the knowledgeable staff at Accurate Forming is there to help with any questions or decisions regarding your deep drawn project.
Accurate Forming offers thread forming as a value added operation in order to provide the customer with one-stop shopping for all deep drawn stamping services. Threads may be added to a part whenever screw threads are required, or simply as a decorative finish to the final product.
