Thread Rolling Dies

The industry regards thread rolling - with its cold forging process - as the preferred method of producing uniform, smooth and precise threads. For example, its benefits versus cut threading include:

• Superior physical characteristics.
  Cold forming improves tensile strength and shear strength, as well as increases resistance to fatigue failure
• Greater accuracy.
  It is easier to achieve pitch diameter, thread angle, lead and taper accuracy over long periods of time
• Uniformity.
  Rolled threads can be uniformly produced at high production rates with no material waste
• High degree of smooth surface finish.
  Due to the slipping and burnishing experienced in the rolling process, the threads produced on the work blank are typically smoother than the dies
• Material savings.
  Since the material pressed out of the thread roots is rolled up to form the crests, no material is removed - yielding savings of approximately 15% on larger diameter threads and 27% on smaller diameter threads.
• Speed.
  Thread rolling is the fastest method of producing screw threads
• Operational savings.
  Since thread rolling dies do not require sharpening, certain costs associated with downtime and labor are eliminated

Extensive Range Of Thread Rolling Dies

Reed-Rico and Hi-Life Tools produce an extensive variety of thread rolling dies, including flat dies, cylindrical dies, planetary dies, thread roll dies and form roll dies/ form plates. With their reputation for world-class quality products, Reed-Rico and Hi-Life Tools offer:

• Thread rolling dies, materials and surface treatments that serve the industry's broadest range of applications
• Dies manufactured from the highest quality tool steels that have superior dimensional and metallurgical properties - to ensure uniformly accurate threads, minimized shimming, elimination of drunkenness and maximized die life
• Conformance to UNR (ANSI B1.1 and MIL-S-7838), UNJ (MIL-S-8879), ISO Metric (ANSI B1.13M) and MJ Profile (ANSI B1-21M) industry standards; dies for other thread forms can be manufactured upon request
• Reed-Rico Patented Flaw Free Form (F³®) dies - for lap-free rolling
• Hi-Life ClassicProfile dies- for rolling exotic materials and after "heat treat" product
• More licensed flat dies than any other supplier
• Standard and special flat dies
• Combination thread and form rolling
• Optimized roll-forming designs using finite element analysis
• Controlled Radiused Root Runout (RRO) - a technique whereby the smooth radius in the thread root continues to the point at which the thread blends in the screw shank; by thus distributing stress evenly, the radius increases fatigue resistance
• Controlled regrinding
• Highest tolerance specifications - including compliance with IFI Standards 109 and 510 - for repeatability, fast set up time, easy die replacement during production runs and lower per-piece threading costs
• Global sales and service centers
• Competitive prices
