Eliminate Annealing & Increase Productivity
With Triform
• No annealing needed
• Production costs down 25 %
• Scrap rates less than 1 %
• Improved weld quality and overall appearance
Before Triform
• 6 Annealing steps
• Thicker starting material
• High scrap rates
• Poor appearance

Supplier Eliminates Annealing , Reduces Costs and Increases Production with Deep Draw Sheet Hydroforming
Aerosud Holdings Pty ., a manufacturer of wing components for commercial airliners located in Pretoria , South Africa , was experiencing a bottleneck in the production of aluminum canisters for the Airbus A320 . The company ’ s traditional forming operations required six annealing steps to draw a 4.50 ” diameter canister 6.50 ” deep .
Excessive thinning in the process — which resulted in high scrap rates — required a starting sheet thickness of . 080 ”. In addition , the high number of anneals affected the quality of the welding in the final assembly and made it difficult to meet demanding delivery schedules .
Aerosud Director of Technology , Dr . Deon Labuschagne , worked with Triform to transfer production to a Triform model 16-10-7DD deep draw sheet hydroforming press . “ Aerosud is now working on the design for the Airbus A350 slat track cans ,” said Labuschagne . “ With the success
we have had on the A320 program we are designing as many components as possible to be formed on our new Triform .”
By moving production to a Triform press , the canisters are now drawn consistently without any annealing . Plus , the steady , uniform pressure of the Triform ’ s internal diaphragm reduced material thinning to only 10 %. This allowed the blank thickness to be reduced from . 080 ” to . 063 ”, offering significant material cost savings .
Precision hydraulic and controls components allow for unprecedented
manipulation of both the diaphragm pressure and punch position throughout the draw , and proven recipe components can be easily saved and recalled at a later date , expediting setup time and ensuring batch-to-batch repeatability .
Thanks to the Triform 16-10-7DD , Aerosud ’ s production costs have been lowered by 25 %, scrap rates have been reduced to less than 1 %, weld quality has been greatly improved , and the overall appearance of the final parts has been significantly enhanced .
“ With the success we have had on the A320 program , we are designing as many components as possible to be formed on our new Triform .”
