THIOT INGENIERIE installed the first hydraulic autofrettage machine in 2000, a machine whose basic principle constituted a technological breakthrough at the time. New ideas were put forward to limit maintenance operations, the number of spare parts to be kept in stock, and especially to make the autofrettage process more reliable. Overnight, the maximum autofrettage pressure was increased to 10,000 bar, a pressure perfectly stabilized in the whole machine and the barrel that had to be autofrettaged.
THIOT INGENIERIE’s autofrettage machines are now tested at 14,000 bar, to work daily at 12,000 bar. They allow the autofrettage of several barrels per day, the number depending on the pressurization protocol for each barrel.
AUTOMATION
- Automatic configuration adjustments in just a few minutes
- Automatic connection of the barrel to be autofrettaged to the mandrel using a carriage (plug & play mandrel)
- Gradual, automated pressurization with precision of 20 bar
up to 11,000 bar
WE ALSO MAKE SWAGING MACHINES
EASE OF USE
- The distance between the two plates is adjustable, to adapt to the length of the barrel to be autofrettaged: easy alternation between different types of barrel
- A single mandrel for the various autofrettage operations, at low and high pressure
- Capacity to check the bore diameter of your barrels with precision of 3 microns: no need for a qualified operator
