METAL FORGING AND ROLLING
Hubs & Tooled Forgings
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. These forces are delivered with a power hammer or press. No other process for working metal can equal forging results in strength and toughness.
At its most basic level, forging is the process of forming and shaping metals through the use of hammering, pressing or rolling. The process begins with starting stock, usually a cast ingot (or a “cogged” billet which has already been forged from a cast ingot), which is heated to its plastic deformation temperature, then upset or “kneaded” between dies to the desired shape and size.
During this hot forging process, the cast, coarse grain structure is broken up and replaced by finer grains. Shrinkage and gas porosity inherent in the cast metal are consolidated through the reduction of the ingot, achieving sound centers and structural integrity. Mechanical properties are therefore improved through reduction of cast structure, voids and segregation. Forging also provides means for aligning the grain flow to best obtain desired directional strengths. Secondary processing, such as heat treating, can also be used to further refine the part.
Forging can create a myriad of sizes and shapes with enhanced properties when compared to castings or assemblies.
Ring Forging Process
We regularly carry out the following forging operations:
- Press forging
- Hammer forging
- GFM forging
- Closed die forging
- Ring rolling
- Bar rolling
We have the ability to convert ingot, billet or bar stock to finished and semi finished products in various shapes and sizes. All in accordance with individual customer requirements.
Shaped components can be forged through the closed die process. We can arrange for dies and tooling to be manufactured in accordance with customer requirements.
We offer many size forgings in both standard and unique geometries to meet your needs.
- Complex Shapes
- Step Shafts, Eccentric Shafts & Rotor Shafts
- Hubs & Tooled Forgings
- Forged & Rolled Rings
- Semi-Closed Die
- Discs & Blanks
Cold forging (or cold forming) is a process that takes cold heading quality wire on heading machines which is cut to required lengths. The “cut off” is transferred through a series of dies (the more complex the part, the greater the number of dies), which produces a “headed blank”. This part of the process determines the size and length and the head configuration i.e. countersunk, cap, pan etc. The recess is also formed at this stage i.e. socket, 6-lobe, pozi etc.
