Castle Machine Standard Features
Clamping Unit
» Optimised force flux and rigidity of clamping system through five point double toggle system.
  Actual locking force is 10% greater than the rated locking force thanks to typical positive locking mechanism of the toggle system,even at high rates of Injection.
  Less jerks & vibration of machine thanks to inbuilt cushion cylinder.
  Platen casting designed with finite element analysis for maximum rigidity.
  The moveable platen ensures uniform clamping force distibution in the molds to obtain a superior planar pressure balance.
  Electrical and hydraulic safety interlocks in mould platen movements for mould & operator safety.
  Multi stage mould open/close pressure & speed control. (5 stage close / 4 stage open.)
  2- stage, multi function hydraulic ejection control.
  Set mode for mould mounting(Low speed & pressure mould Open/close function.)
  Automatic toggle lubrication system by central lubrication device.
  Adjustable moving platen support (>180 tonnes)
  Pre-tensioned tiebar for reliable endurance.
  Automatic mould height adjustment through sun gear mechanism
  Graphite impregnated oiless bushes used to reduce wear& tear of clamping mechanism.
  Safety doors with clear PMMA windows
  Frame with catch tray and guide channels to collect surplus oil and keep machine frame clean.
  Fixed cover over top of toggle set for safety & to keep toggle area clean of workshop dust.
  Low dry cycle tim

Injection Unit
» Twin cylinder balanced injection system.
» Sub-flighted screw for better melt quality and low temperature plasticisation so reduction in mold cooling time
» Casle type ring plunger for better shot weight accuracy.
» Very high speed, high response closeloop injection ensures superior reproducibility & stabilised quality of moulded products.
» High injection power,high rigidity of platen & fast cycling parallel machine functions very useful for producing very thin & deep products with shortest cycle time.
» 10 stage injection phase pressure/speed/position control. (selectable 5 to 10 )
» 5 stage holding phase pressure/speed/time control. (selectable 3 to 5 )
» 3 stage plasticizing pressure/ speed / position control.
» Injection to holdon Switchover on time, pressure & position control.
» Automatic purging function
» High torque motor for screw pasticization
» Wide selection of special application screw & barrels
» PID barrel temperature control device
» Nozzle centering allignment device.
» Screw speed indication on MMI
» Short circuit proof SSR control circuit for heater bands

Hydraulic
» High quality energy saving variable delivery pump / fix delivery pump.
» High quality pressure line filter with clogging signal enhances long service life of machine components.
» Seperate oil filteration & oil cooling circuits maintains oil quality & oil temp. even at very fast cycling useful for mass production.
» Hydraulic circuit consisting of a high capacity accumulator combined with a high response servo valve for closeloop injection function & proportional flow/pressure valves for controlling rapid open/ close mould platen movement.
» Regenerative hyd. circuit achieved very high platen speed more than 1200 mm/sec.
» Return line oil filter with clogging alarm signal
» Plate type oil cooler(Highly efficient & easy maintenance)
» Oil tank air breathers with filters.
» Provision to isolate oil tank for maintenance
» Efficient piping by using max.no. of hoses thus achieved zero oil leakage.
» Easy maintenance

Control System

» Running function display by LED on function keys & status message on MMI.
» Machine cycle timing details in a single screen.
» Temperature setting resolution in 1 degree centigrade.
» Hourly & monthly production monitoring system with cumulative production counters.
» Membrane keys to operate machine axes and application options
» USB interface to connect storage media(pen drive)
» Control panel temperature display and interlock for overheat.
» Cabinet ventilation and fan cooling.
» Swivel-mounted control panel in operation station.
» Events protocol (logbook) for more than 1000 events with help menu & facility of copy to pen drive
» Stastical process control of 15 nos.various critical parameters for last 100 machine cycles
» Extra electric power supply socket-1 no
» Analog input/output monitoring in milli volts
» Graphical display with history of selected function for last 5 cycles
» Auto calibration for linear transducers
