The United States uses ANSI’s American National Standard Pipe Thread Standards to regulate the formation and sizes of screw threads on manufactured parts with straight or tapered threads. These standards ensure that separate pieces fit together properly for specialized attributes such as pressure-tight sealing and rigidity.
Thread rolling is a metal forging process that forms threads into the mirror image of a roller die. The process is different from metal cutting, grinding, and chasing because it does not remove any metal from the workpiece. Instead, thread rolling uses hardened steel dies to displace and mold ductile metals. The high-pressure process physically changes the properties of rolled metal parts to make the base part and the threads harder and stronger.
Most frequently used in the production of threaded rods, bolts, screws, and other metal fasteners, thread rolling is a cold metal forming process that creates threads using precision thread rolling dies that are the mirror image of the thread being produced. Though a reliable and flexible practice, there are a number of techniques that can improve your output. Extensive experience in thread rolling makes CJWinter’s team of well-versed experts the go-to source for anticipating and preventing common thread rolling problems.
In these unprecedented times, and their ever-changing, always-challenging impact on manufacturing and supply chain, CJWinter would like to let you know that while supremely focused on safeguarding the health and welfare of our workforce, we remain committed to providing superior customer & partner services. We continue to produce the highest quality thread rolls with unparalleled delivery times.
Since the company’s incorporation in 1956, the team at CJWinter developed a reputation for the fast and efficient production of thread rolled products. Our top priority is giving customers a competitive advantage, which we do by leveraging experienced engineers, superior customer support, and online resources.
An Introduction to Thread Rolling
Thread rolling is a cold forming or cold metal forming process that creates threads using precision thread rolling dies that are the mirror image of the thread being produced. This process is different from other processes like metal cutting, grinding, and chasing because it does not remove any metal to create the desired profile. Instead, these hardened steel thread rolls move and mold ductile metals quickly and very precisely into desired thread form.
Every year, the PMPA Technical Membership Chairman’s award is given to the outgoing Chairman in gratitude for his or her exceptional leadership and service throughout the year. We are proud to say that this year, CJWinter’s own Liberato Pietrantoni received the award for his work in this role. It was a great year for PMPA and our company, and we’re happy to have worked closely with this organization.
In today’s fast-paced manufacturing environment, delivering products ahead of time is more important than ever. OEMs and other production facilities operate under increasingly tight deadlines, so ensuring that their supply chain exceeds their expectations is crucial to success.
Taps, dies, bolts, and other helically threaded parts are defined by a number of measurement parameters. Some typical thread dimensions include pitch, depth, angle, and major and minor diameters. Among these dimensions, the pitch diameter is considered to be one of the most crucial.
