The key to the SuperShot III's spectacular performance is precision. Programmable
real-time closed-loop CNC control of all injection phases provides maximum shot
consistency and repeatability. Flash and porosity are reduced drastically, and
surface finish and stability are greatly improved. Here is a walkthrough of a
typical shot, with a profile from each of the stages.
1st Phase/LIFT-OFF:
Absorbs initial oil surge from accumulator to prevent shock wave in the metal
and prevent gas entrapment. Remains constant for all setups.
2nd Phase/CLOSE POUR HOLE:
Advances plunger past the pour hole with precisely controlled velocity and fills
cold chamber to minimum 50% full. Remains constant for all setups.
3rd Phase/SLOW APPROACH:
Precisely controlled at the "critical slow shot velocity" to eliminate waves
and turbulence in the metal. Prevents porosity caused by gas entrapment.
4th Phase/FAST SHOT:
Industry's fastest acceleration to high cavity filling speed. Closed-loop control
even at maximum injection speed provides the best reproducibility possible.
Automatically compensates for other variables to prevent defects.
5th Phase/LOW IMPACT:
Industry's fastest deceleration allows higher fast-shot velocities to obtain less
porosity and better surface finish without flash. Increases machine's effective
clamping tonnage by 25 to 50%. Unique Tymac flexible control by metal pressure or
position compensates for ladle variation automatically.
6th Phase/FINAL FILL:
Increases Metal Pressure within milliseconds after LOW IMPACT to increase casting
density and prevent porosity without excessive flash.
7th Phase/FINAL SQUEEZE:
Unique Tymac flexible control of intensifier by metal pressure, position, and time
automatically compensates for stroke variation. The faster response with consistency,
through Tymac Intensimax Control, delivers minimum porosity and optimum properties.
