Whitepaper - Quintus Purus® Enabling clean processing in Hot Isostatic PressingWhite paper
Quintus Technologies has supplied high-pressure rubber diaphragm presses to the world’s major aircraft manufacturers for decades, such as Airbus, Boeing, Bombardier, Embraer, Alenia, British Aerospace, Aerospatial, EADS, Cessna, China Aviation, Mitsubishi, Kale Pratt & Whitney, Daber-Socata and many more.
The availability of ultra-high forming pressures greatly increases the range of sheet metal parts that can be formed economically. The final shape can be achieved in fewer steps and with less manual correction. Also, heavy gauge and difficult materials can be formed into complex shapes with close tolerances. Trimming can be included in the press cycle.
“We make hard-to-manufacture sheet metal aerospace components and assemblies from a broad variety of materials. The Quintus press will enable us to produce very complex, high profile parts that require a deep draw function. A reflection of our commitment to relentless, continuous operational improvement, it is expected to help achieve our ambitious production goals spurred by the current growth in the jet engine arena. ”
Mr. Allen Roy, Engineering Manager, Whitcraft
Whitcraft Group Gears Up for Aerospace Growth with Quintus Hydroform Press. Press eliminates forming operations, intermediate heat treatments, and operator dependencies, cutting manufacturing lead times by half. Thirteen months after being tapped to supply $234 million in parts and assemblies for Pratt & Whitney’s next-gen geared turbofan engines, Connecticut’s Whitcraft Group inaugurated a brand-new Quintus hydroform deep-draw press at its Eastford sheet metal facility.
Quintus offers a full line of standard models of Flexform™ Presses with rectangular trays dimensions up to 1.8 x 3.6 m (71 x 142 in) and pressures from 800 bar (11,600 psi) to 1,400 bar (20,000 psi). The cycle time is normally one to three minutes, depending on press size, formed parts and selected pressure.
QFL presses are compact units with circular trays, designed for faster forming of smaller parts.
Cycles average about one minute, with maximum pressure of 800 bar (11,600 psi). These presses are commonly used for off-loading and back-up for larger rectangular tray presses and for rapid forming of smaller parts.
Quintus offers a line of standard deep-draw press models with forming area/diameter ranging from 560 mm / 22 inch to 1100 mm / 43.3 inch. Pressure ranges from 800 bar / 11,600 psi to 1,200 bar / 17,400 psi. The cycle time is depending on the tool size and the pressure level required, but normally range from some 30 seconds to two minutes.
The Flexform™ High Pressure Warm Forming process is a new technology that can replace or complement existing Titanium forming methods, such as hot-forming, hot stamping, super plastic forming, SPF, and hot gas forming. Benefits: 50% reduction in production costs, five times increased throughput, and forming repeat-ability
Airbus hood component in 0.8 mm (0.03 in) stainless steel formed in a hardwood cavity die in one operation to 1,400 bar (20,000 psi). The part was previously made in three operations in a rubber pad press, with high reject rate.
