ENGEL DUO 5550/1100 Injection Moulding Machine

Year of manufacture: 2011

Injection Unit

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

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.
Plasticising capacity: 85 g/s (for polystyrene, screw Ø 90 mm).

Injection unit equipment:
M3-type barrel – bimetallic, increased resistance to corrosion and wear, permissible temperature up to 350°C.
S4V-type screw – heat-treated, chromed, with wear-resistant edges, increased corrosion and wear resistance.
Special G11.3 screw geometry optimized for process.
Return valve R12 (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 stretchers on the ejector side.
Two fast-movement cylinders mounted diagonally on the clamping system.
Mould opening stroke dependent on mould height (dynamic stroke adjustment).
Movable platen guided on the machine frame – ensuring platen rigidity and parallelism.
Clamping force: 11,000 kN.
Mould mounting platen dimensions: 1,850 × 1,810 mm.
Tie bar spacing: 1,400 × 1,150 mm.
Mould height: 600–1,200 mm.
Maximum opening stroke: 1,800 mm.
Mould cooling system: 10 water circuits with rotameters (max. 30 l/min each).
Special platen design with additional holes for ejector system in two configurations (horizontal and vertical).

Core Drives (Core Pull Systems)

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

Hydraulics

Pump station with pressure- and flow-controlled electrohydraulic pumps, as well as fixed delivery pumps.
Energy-efficient proportional hydraulics with precise flow and pressure regulation.
Bljdpfxew U Taxs Altol
Servo valve for control of injection speed, hold pressure, and back pressure.
ECODRIVE system – energy-saving hydraulic drive ensuring parallel auxiliary movements with minimal energy consumption.

ENGEL Viper 40 Robot

Integrated Cartesian robot, operated via CC200/RC200 control system.
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: rotatable gripper 0–90°, pneumatic drive.
B axis: head rotation around lift axis (Y), servo motor drive, range +90° / –180°.
