Forgings

Introduction

Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
When it comes to forging, there are four main ways to forge a part. Those four are impression die forging, cold forging, open die forging and seamless rolled ring forging.

Types of Forgings:

Chain Link, D Shackle, Bow Shackle, Single Jack Chain, Lifting Chain, Double Loop Chain, Special Bow Shackle w/ No-Snag Pin, Open Die Forging, Closed Die Forging, Seamless Rolled Ring, Crane Hooks, Step Shafts, Forged Hollow Bars, Anchor Shackle, Safety Chain Shackle, Bolt Chain Shackle, Forged Flat Bars, Forged Circles, Forged Circular Plates, Joining Shackle, Forged Discs, Mandrel Rings, Shafting & Bars, Long Link Chain.

Specification of Forgings:

  • Dimension: ASTM, DIN, BS, GB, IS and all International Standards

  • Forged Between : 2300/1700°F (1260/930°C) and air cooled

  • Severe Reductions : Ingot breakdown, Roll forging, Drawing, Blocking and Backward extrusion – 2300°F (1260°C).

  • Moderate Reductions: Finish forging and upsetting- 2200°F (1200°C).

  • Slight Reductions : Coining, restriking and end upsetting- 2050°F (1120°).
