Twin Station Hollow Extrusion Blow Molder for 10L Plastic Jars

The MP70FS twin station hollow extrusion blow molder is built around a shuttle clamping layout that lets two moulds work in parallel, raising jar output without lengthening the cycle. It is a dependable choice for 10 L plastic jars that must hold shape, seal cleanly, and stack neatly.

A 70 mm screw, electro-hydraulic proportional control, and a parison programmer cooperate to keep jar walls uniform and jar necks burr-free, so downstream capping and filling lines run without interruption.

• Twin Station Parallel Moulding: Two clamping stations alternate automatically, nearly doubling the number of jars produced per cycle while drawing moderate power.
• Hollow Body Built for 10 L: The 150 kN clamping force and 500 x 360 mm platen handle large hollow jars with stable mould locking and no deflection.
• 70 mm Screw Plasticizing 90 kg/h: High melt output keeps jars at consistent weight and thickness across a full shift.
• Automatic Neck Calibration: The down-blowing blow pin trims and calibrates the jar neck during inflation for a smooth, burr-free sealing edge.
• Zero-Drift Flashing Control: A liquid control one-way valve hydraulically locks the clamping circuit to eliminate flashes and improve the parting-line appearance.
• Centralized Microcomputer Control: Sequencing, heating, and parison profiles are managed from one panel with forty stored mould recipes.
• Anti-Cold-Start Protection: The variable-frequency extrusion drive cannot rotate until every barrel zone reaches its set temperature, protecting the screw.

Large plastic jars for jams, sauces, pickles, and dried foods are a natural fit, because the twin station layout keeps up with high daily demand.

The machine also produces industrial and household jars for paints, adhesives, cleaning agents, and lubricants, where a sturdy hollow body and a leak-free neck are essential.

Q: What does twin station mean on a blow molder?
A: Twin station refers to two clamping stations that alternate under one extruder, so the machine forms two mould sets per cycle and raises jar output without a longer dry cycle.

Q: Can it mould 10 L jars reliably?
A: Yes. The 150 kN clamping force and generous platen size hold large jar moulds firmly, keeping walls even and preventing mould deflection at high pressure.

Q: How is the jar neck finished?
A: A down-blowing blow pin calibrates and trims the neck during inflation, leaving a smooth, burr-free edge ready for capping.

Q: Is operator safety covered?
A: The machine uses Category-4 safety door interlocking with dual limit sensors, cutting clamping power the moment a guard opens.

Every unit is packed in a standard export package with an optional wooden pallet or wooden case for long-distance sea freight. The machine is CE and ISO9001:2008 certified and is supported by remote commissioning, operator training, wearing-part supply, and responsive after-sales service worldwide.
