Machined Forgings


Machined Hot & Cold Forging manufacturer

AmTech International’s forged component division specializes in cold forging and hot forge manufacturing processes.

Forging is a manufacturing process where the metal is hammered, pressed or rolled under high, localized pressure and shaped into high strength parts known as forgings. This metal working method has been in use for centuries and was traditionally deployed in the manufacture of tools, weapons, kitchenware and jewelry.

During the forging process, the coarse grain structure of the metal is broken down into finer grains, and a grain structure that is better aligned towards the desired directional strength can be obtained; in addition, gas porosity and low-density/empty spaces may be removed, and cracks sealed during the process. Forging thus produces parts that are much stronger than those produced by any other metal-working process. Forgings are therefore widely used in applications where great strength is required and reliability and human safety are critical.

Cold Forging Advantages

  • Reliable and cost efficient process.
  • Savings in material and final machining.
  • Increased dimensional control.
  • Parts require very little or no finishing.
  • Less susceptible to contamination issues.
  • Favorable crystal grain flow increases toughness of the part.
  • Final component features offer a better overall finish.
  • Long die life.

Hot Forging Advantages

  • Main advantage of hot forging is that as the metal is deformed the strain-hardening effects are negated by the re-crystallization process.
  • Parts possess increased ductility which makes them desirable for many configurations.
  • Homoginized Grain Structure.
  • Porosity free surface quality enables a wide range of completion operations such as polishing or surface treatment.
  • Efficient process when working with harder metals such as steel.
