Hydraulic Press Draw Force Calculator

Two different draw force estimators are available…one for circular parts and one for rectangular parts. For circular parts, just enter a few parameters (material yield strength, thickness, draw and blank diameters) and, PRESTO, the drawing calculator gives you draw tonnage and total tonnage figures. For rectangular part jobs, enter a similar parameters (material yield strength and thickness, as well as corner radius and straight line lengths) and draw tonnage and total tonnage figures are given.

CALCULATOR DESCRIPTION »

Input values in the boxes. Click here for yield strengths. Note: This provides an estimate of the tonnage necessary to draw form a circular part. Actual tonnage should be confirmed with the manufacturer of the die.

* Holding or cushion tonnage is estimated at 1/3 of draw tonnage. Actual tonnage will vary as required to achieve a quality part.
