Servo Hydraulic Blow Moulder with 120-150 kg/h HDPE Drum Output

On a large blow molding machine the hydraulic pump runs all shift, whether or not the machine is clamping. A fixed displacement pump therefore burns power during cooling, during parison drop and during every idle minute of a 120 second cycle. The MP100FD uses a servo driven hydraulic pump that only delivers what the cycle asks for.

Measured across a full shift of 100 litre drum production, that control strategy cuts energy consumption by 25 to 30 percent against a conventional fixed pump of the same rating. On a machine installed at roughly 55 kW, the saving is not a rounding error in the electricity bill.

• Servo driven hydraulic pump: Pump output follows actual demand, removing the fixed losses of a constant displacement system
• 25-30 percent energy saving: Verified against a conventional fixed pump on the same 100L drum cycle
• 120-150 kg/h HDPE output: 80 mm, 25:1 nitrided screw keeps melt supply ahead of the accumulator
• Lower oil temperature: Less wasted energy means the oil runs cooler, extending seal and valve life
• Quieter operation: Servo pump idles at low speed instead of running at full displacement
• 55 kW installed power: Compact electrical demand for a machine of this clamping capacity

• Drum and barrel plants with high electricity cost
• Factories with limited transformer headroom
• Continuous three shift container production
• Plants measuring kWh per finished container
• Large part moulding where cycle time is cooling dominated

A: With a power analyser on the incoming supply, comparing the same 100L drum mould and material against a fixed pump machine of equal rating over a full shift. We can supply the method and a sample log so a buyer's own engineer can repeat the test after installation.

A: No. Clamp, carriage and blow sequences reach the same speeds because the servo motor responds faster than a fixed pump with proportional valves. Cycle time is unchanged or slightly better.

A: The same oil and filter regime as a conventional hydraulic machine, plus a periodic check of drive cooling. Servo pumps have fewer moving parts than variable displacement piston pumps, so overhaul intervals are usually longer.

The machine is shipped with hydraulic oil drained, ports capped and the cabinet sealed with desiccant inside a fumigation-free export wooden case. Delivery is 30 to 45 working days after deposit. ISO 9001:2015 and CE certification, a 48 hour dry run report, 12 month warranty and remote technical support come with every unit.
