Practical design calculators for press sizing, feeding ratio, die land length and material selection — built for tooling engineers worldwide.
Select a module below
Extrusion ratio (EX) and feeding ratio for porthole dies; billet and profile sizing.
Open module →Estimate required extrusion pressure, all-in force and projected press tonnage. Plastic die head pressure too.
Open module →Base land length from wall thickness and equalised land for varying profile sections.
Open module →H13 / H11 die steels, extrusion alloys and common plastics with recommended parameters.
Open module →Compression and buckling check for porthole-die mandrels and support pillars.
Open module →Bending and shear check for porthole-die bridges under uniform or midspan point load.
