1L HDPE Bottle Extrusion Blow Molding Machine, Hydraulic Driven

The MP70D-2 is a hydraulic driven extrusion blow molding machine that MEPER has refined across more than a decade of field service on bottle lines in Europe, the Middle East and Southeast Asia. It targets one group of products only, HDPE bottles from 10 ml up to 1 L, and it is tuned for the operators who run those moulds every day.

Every movement that decides bottle quality is hydraulic: clamping, carriage and blow pin travel respond directly to proportional valve commands, so pressure stays repeatable from the first shift to the third. Electrical sequencing on top of that hydraulic base keeps cycle timing identical whether the machine is starting cold in the morning or running at full temperature after eight hours.

• Hydraulic driven clamping: Direct-acting hydraulic cylinders deliver 90 kN of clamping force, so mould flash stays controlled even with thin-wall 1L HDPE parisons
• Double station layout: Two stations with two die heads cut idle time between shots and roughly double output against single station frames of the same footprint
• 70 mm screw, 24 L/D: Optimised compression ratio for HDPE gives 70 kg/h plasticizing capacity with stable melt temperature
• Proportional hydraulic control: Pressure and speed ramp smoothly, protecting mould parting lines and extending blow pin life
• TECHMATION control system: Recipe storage, alarm history and cycle counters in one interface that a line operator can learn in a single shift
• Auto lubrication and FRL unit: Centralised lubrication plus filtered and regulated air supply reduce unplanned stops on long runs

• Lubricant and motor oil bottles from 250 ml to 1 L
• Agrochemical and fertilizer containers requiring thick walls
• Household cleaner and detergent bottles in HDPE
• Automotive fluid and coolant bottles with handle inserts
• Personal care and industrial chemical packaging lines

A: Actual output depends on wall thickness and cooling time, yet the double station design with two die heads typically returns twice the cycle count of a single station frame. For a 1L lubricant bottle at 2.5 mm wall we normally quote 900 to 1100 bottles per hour, and we confirm the figure from a mould trial before shipment.

A: In practice it reduces wear points. There are no toggle pins or bushes to adjust, force is generated inside the cylinder, and the proportional valve block is a standard industrial item that any local hydraulic shop can service. MEPER supplies a full seal kit with every machine.

A: Platen opening stroke runs from 180 to 480 mm, so a 1L single cavity mould and a 500 ml two cavity mould both fit without modification. Positioning holes for quick mould change are standard, and we can prepare a second mould plate set for faster changeover.

Each MP70D-2 is inspected under power before dispatch, then protected with rust preventive film, anchored on a wooden pallet and crated in a plywood case with the control cabinet packed separately. Delivery is 25 to 35 working days after deposit. The machine carries CE marking and ISO9001:2008 production control, with a 12 month warranty, remote commissioning support and a spare parts list supplied in English.
