ENGEL DUO 5550/1100

ENGEL DUO 5550/1100 Injection Moulding Machine

Year of manufacture: 2011

Injection Unit

Two short-design injection cylinders for plasticizing.
Direct screw drive; ceramic heaters on the cylinders.

Standard screw geometry L/D = 22.
Hardened and nitrided screw, diameter Ø 90 mm.

Maximum injection volume: 2,740 cm³.
Maximum shot weight (PS): 2,520 g.

Open nozzle: front radius R = 35 mm, channel diameter Ø 6 mm, mounting thread M55×3.

Increased specific injection pressure: 2,180 bar.
Plasticizing throughput: 85 g/s (for polystyrene, screw Ø 90 mm).

Injection unit equipment:
M3-type cylinder – bimetallic, increased corrosion and wear resistance, permissible temperature up to 350°C.
S4V-type screw – heat-treated, chrome-plated, with armoured edges, increased corrosion and wear resistance.
Special screw geometry G11.3, optimized for the process.
R12 non-return valve (multi-ball, recommended for PC, PMMA, ABS).

Clamping Unit (Clamping System)

Hydromechanical two-platen clamping system.
Four short high-pressure cylinders on the nozzle side.
Four tie-bar tensioners on the ejector side.
Two fast-movement cylinders mounted diagonally within the clamping system.
Mold opening stroke dependent on mold height (dynamic stroke adjustment).
Moving platen guided on the machine frame – ensures platen rigidity and parallelism.
Clamping force: 11,000 kN.

Mold mounting platen dimensions: 1,850 × 1,810 mm.
Tie-bar spacing: 1,400 × 1,150 mm.
Mold mounting height: 600–1,200 mm.
Maximum opening stroke: 1,800 mm.
Mold cooling system: 10 water circuits with rotameters (max. 30 l/min each).
Special platen design with additional holes for ejector system in two arrangements (horizontal and vertical).

Core Drives (Core Pull Units)

Independent hydraulic core pull drives in the mold: 2 units on moving platen, 2 units on fixed platen.
Hydraulic pressure reduction systems for core circuits.
Independent pneumatic core pull drive on both moving and fixed platens.

Hydraulics

Pump station with electrohydraulic pressure and flow-controlled pumps and fixed displacement pumps.
Energy-efficient proportional hydraulics with precise flow and pressure control.
Servovalve for controlling injection speed, hold pressure, and back pressure.
ECODRIVE system – energy-saving hydraulic drive enabling parallel auxiliary movements with minimal energy consumption.

ENGEL Viper 40 Robot

Integrated Cartesian robot, controlled from CC200/RC200 panel.
Three servo-driven axes: X = 700 mm (extendable to 900 mm), Y = 1,000 mm (tandem up to 1,900 mm), Z = 1,880 mm (extendable to 5,720 mm).
Payload up to 17 kg, accuracy ±0.05 mm.
C axis: rotating gripper 0–90°, pneumatic drive.
B axis: head rotation around lift axis (Y), servomotor drive, range +90° / –180°.
