Special Tooling Design and Springback Control for Acute Angle Bending (<90°)
2026-08-02

Abstract: Bending sensitive alloys or high-tensile sheet metal below 90 degrees triggers massive material springback and rapid punch tip wear. Standard 88° air bending tools cannot achieve proper over-bending on acute profiles. This technical guide outlines how specialized acute tool profiles, 30° tool steels (like H13 or SKD11), and precision over-bending calculations eliminate angle variations without cracking the material skin.

How to Match Press Brake Punch and Die: A Shop-Floor Safety & Setup Guide
2026-07-23

How to Match Press Brake Punch and Die Without AccidentsAnyone who works with press brakes knows: 8 out of 10 problems aren't caused by bad tooling — they're caused by mismatched punch and die sets. Get the punch and V-die wrong, and you'll get every problem in the book: off-angle bends, deep press
Press Brake Tooling: The Shop Floor Guide To Selection, Materials, Maintenance & Industry Solutions
2026-07-22

Key TakeawaysPress brake tooling — punch on top, V-die on bottom — bends sheet metal by forcing it to plastically deform under pressure. And here's the thing: a lot of the headaches on the shop floor trace back to tooling. Surface marks, chipped edges, short die life — those are almost always toolin
