Mechanical Requirements
• High elongation
• High Yeld Strengh
• High Ultimate Strengh
• Heat treatment
Rheinfelden source
• Large frontal area
• Thin walls
Combination of
That means:
• Large HPDC machine size
• Short filling time i.e. high 2nd phase velocity
NoX Integrated Strategy
Twin Valve High Dynamic close loop control (TVHD ICS)
Fig. 7 TDP "Twin valves" system
10 Mts/sec Injection velocity
Setting and actual velocity values excellent matching
Setting and actual velocity values excellent matching
Overlapping the two curves it’s possible to appreciate also graphically the excellent matching between setting and actual result of fastdynamic and accurate response time both electronic as well hydraulic
2nd phase velocity as high as 10 mt/sec, good
injection parameters stability (Cmk > 1,33) combined
with traditional rigidity of IDRA clamping unit, are
associated to high vacuum technology
NoX
Micro porosity due to turbulence and shrinkage heavily reduces mechanical properties
NoX Technology
o Deep die cavity vacuumMinimized gases contents
oAvoid metal oxidation because no contact to air(noOxides)
