    Tube Mills and Pipe Mills - (18 companies)
    Tube mills and pipe mills fabricate metal tubes and pipes. Tube and pipe mills typically consist of a series of machines to form, weld, and cut metal plate or sheet to finished tube or pipe form. Tube mills and pipe mills produce tubes and pipes...
  • Thread Rolling Machines-Image
    Thread Rolling Machines - (34 companies)
    Thread rolling machines generate threads by displacing and flowing metal into a thread shape. Thread rolling machines are used to produce screws, bolts, and studs. Thread rolling is a cold-form forming operation used to form external screw threads...

    ...such as thread mills and threading inserts. Thread Rolling Machines and Standard Workface. Thread rolling dies are designed to fit thread rolling machines made by companies such as Winter, Landis, Detroit, Davenport, Reed and Salvo. When selecting...
  • Forging Machines (hot forming)-Image
    Forging Machines (hot forming) - (31 companies)
    Forging machines (hot forming) use compressive force and a high workpiece temperature to shape metal by plastic deformation. A type of hot forming, hot forging involves the plastic deformation of a metal at a temperature and strain rate where recrystallization and deformation occur simultaneously. This prevents strain hardening, which can reduce ductility and contribute to brittle failure and structural fatigue.
