.: Near Net Shape Forging
What is it?
- Typically takes 6 Seconds
- No material loss
- Finished forging weight = starting billet weight
- High degree of material deformation
Orbital cold forging is a forging process where a fixed bottom die and a moveable/orbiting top punch come together to form complex geometric workpieces with finished dimensional accuracy in a single forging operation. The orbiting upper die rolls over a metal blank while the bottom die is raised hydraulically. The billet is kneaded into the bottom die with relatively little force to produce a NEAR NET SHAPE or FINISHED workpiece.
Why use orbital cold forging?
1. SAVES MONEY
- No material waste — Near net shaping is a chipless operation
- Simplifies Manufacturing — Eliminates expensive secondary machining and brazing operations
- Inexpensive long life tooling
- Automated material handling — All presses equipped with robotic loading and unloading
2. INCREASE MATERIAL STRENGTH
- Strength, hardness and surface finish improved through orbital cold working
- Grain structures rearranged
- Less expensive materials achieve tensile strength upgrades after the orbital cold working process
3. CONSISTENT QUALITY
- Higher strength to weight ratios in structural components
- Low friction forging operation extends die life
- Repeatable low force forging process yields accurate manufacturing runs
