PowerJet DP series

PowerJet DP series – Two-platen large machines, 650–3,300 t

The PowerJet DP series is the top of the large-machine range distributed by CIS, designed specifically for the high-volume production of large, deep-cavity plastic parts. The defining feature of the series is the two-platen direct-hydraulic clamping unit: in place of the rear platen and toggle linkage used in conventional toggle machines, four high-stroke hydraulic clamping cylinders are integrated into the moving platen. This design brings two important benefits: at the same clamping force, the machine length is 10–20% shorter than that of a toggle machine; and the opening stroke is unrestricted — the top-of-range DP3300-S6 reaches a maximum daylight of 4,200 mm.

The servo-hydraulic drive controls the hydraulic pump via a variable-speed servo-motor, so the machine consumes only as much energy as is actually needed at any given moment. This represents a 30–50% energy saving compared with a conventional hydraulic machine. Linear-rail moving-platen guidance provides low friction, long service life and accurate positioning. Automatic mould-thickness adjustment means there is no need for manual setting after a mould change.

The KEBA control system has a 12-inch touchscreen, a 100 μs processing cycle and 1,000 mould-memory positions. The series ranges from 6,500 kN (DP650-S6) to 33,000 kN (DP3300-S6) across 12 machine sizes — covering the entire large-part injection moulding segment, from logistics pallets through to automotive body panels.

Key features

• Max. daylight: 1,850 mm (DP650) – 4,200 mm (DP3300)
• Servo-hydraulic drive: 30–50% energy saving
• Linear-rail moving-platen guidance – low friction, long service life
• Automatic mould-thickness adjustment – no manual setting after a mould change
• Synchronous split-nut locking mechanism – fast, accurate, low-noise
• KEBA control: 12″ TFT, 100 μs CPU, 1,000 mould-memory positions
• Optional: servo-motor plasticising (further 30%+ saving)

Fields of application

• Logistics: pallets, transport boxes, containers
• Environmental industry: 240 L – 1,100 L wheelie bins, composters
• Automotive: bumpers, spoilers, bonnet panels, large interior parts
• Packaging: IBC containers, plastic drums, industrial tanks
• Domestic appliances: washing-machine drums, refrigerator frames, large appliance housings
• Infrastructure: road barriers, large drainage components, signage-pole housings

Why choose this machine?

• A single machine series from 650 to 3,300 tonnes – uniform platform, uniform service
• Deep-cavity products cannot be moulded on a toggle machine – the DP is the only solution for 1,100 L+ wheelie bins or deep pallets
• Smaller footprint = lower hall-rental cost for the same capacity
• No manual setting at mould change = shorter downtime
• 30–50% energy saving with servo-hydraulic drive
• Optional servo-motor plasticising – further 30%+ saving
• KEBA control developed for the EU market – reliable, European-made controller
• CIS exclusive distributor – local service, spare parts, commissioning, training
