Discover The Advantages Of Induction Heating!
Induction Benefits
-
Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
-
Increases production rates with faster heating cycles
-
Reduces defect rates with repeatable, reliable heat
-
Eliminates variability from operator-to-operator, shift-to-shift
-
Maintains metallurgical characteristics of the individual metals

Benefits
Here are the advantages of hot forming with induction heating:
- springback effect is eliminated
- ductility is improved
- low pressure & minimal residual part stress
- better grain flow & microstructure
- improved mechanical properties
- reduced need for post production tempering & heat treating
- improved production rates with minimal defects
Expertise
Induction heating in hot forming is applied for several different purposes:
Heading - forming a head on blot, screw or rivet
Blanking - cutting a whole piece from sheet metal
Punching - cutting a hole
Slotting - cutting of elongated holes
Perforating - cutting a group of holes
Trimming - cutting away excess metal
Shearing - cutting in straight line across piece
Bending - producing single, double, straight flange, edge hem, curl or double hem bends
In order for the hot forming process to succeed, an application should be tested including the following variables. Ambrell's experienced applications engineers will provide you with the necessary advice and recommendation.

How Can Hot Forming with Induction Improve Production Speeds?
Consistent uniform heating with induction helps reduce scrap and process variations.
-
Is there a variable that falls between Warm Form and Hot Form?
yes, however the temperature achieved should not change the material properties of the metal.
-
Are there any limitations with bending when using hot forming?
Usually bending with hot forming is optimal.
