Tonnage calculator
Estimate air-bending force from material strength, thickness, bend length and V opening.
ExplorePress brake resource centre
Choose a machine, estimate the bend and understand the process. Find Carter’s calculators, buying advice and technical guides in one place.
Calculate, compare and plan
Bend allowance & flat length
Calculate blank length and bend centres for L, U and Z profiles using your bend data.
ExploreV-opening & minimum support calculator
Compare V openings, estimated radius and minimum bend-centre-to-edge support. This is not a finished outside flange dimension.
ExploreBend Studio
Explore profiles, candidate bend sequences and tooling clearance before discussing the job.
ExplorePress brake buyer’s guide
Plan capacity, controls, tooling and installation. Print the checklist for your team.
ExploreElectric vs hydraulic press brakes
Compare drive systems around the same component, tooling and workload.
ExploreUnderstand the bend
Press brake crowning explained
Crowning compensates for machine deflection under bending load. It helps keep the angle consistent along a long bend.
ExploreAir bending vs bottoming
The bending method changes the tooling, force and flexibility you need. Confirm the process before comparing machine capacities.
ExplorePress brake springback guide
Springback is the change in angle as a bent sheet relaxes after unloading. Judge the finished part after the bending force is removed.
ExploreBending by material
Stainless steel bending guide
Plan the grade, finished appearance and bend geometry together. A stainless part needs more than a thickness and a machine ton rating.
ExploreAluminium bending guide
Identify the alloy and temper before choosing a tight radius. Aluminium grades and material conditions do not all bend in the same way.
ExploreMild steel bending guide
Use the material certificate and part drawing to turn a nominal machine capacity into a useful bending enquiry.
ExploreUse estimates to start the conversation
Calculators support planning. They do not approve a machine setup, tooling load or collision clearance. Confirm the exact machine, material, tooling and safe procedure before production.

Send the material, thickness, working length and a drawing with your enquiry.
