Four Cavity Blow Moulding Machine with PLC Control for 20L Jerry Cans

Jerry can production rewards cavity count more than screw size. A 20 litre can is small enough that four cavities fit the platen, and each extra cavity multiplies output without adding an operator or a metre of floor space. The MP100FD supports up to four die heads on the same accumulator body.

Managing four cavities is a control problem as much as a mechanical one. Every head needs its own flow balance, every cycle needs identical blow timing across cavities, and every mould change needs the settings recalled rather than retyped. The PLC recipe system covers all three.

• Four cavity output: Four 20L jerry cans per cycle on the 800 x 600 mm platen with 180 kN clamping
• Per-cavity balance: Flow channels machined and balanced so each can weighs within a couple of percent of the others
• PLC recipe control: Stored settings per head configuration and mould, recalled by name at changeover
• Synchronised blow timing: All cavities blow from the same trigger, so wall distribution matches across the platen
• Automatic deflashing: Pneumatic cutters handle four parts per cycle without manual trimming labour
• Closed loop cooling: Chiller circuit keeps mould temperature even across all four cavities

• 20L jerry cans for lubricants and edible oils
• 20L agrochemical and fertiliser containers
• 10L and 15L chemical bottles with handles
• Stackable industrial containers
• Contract runs for private label packaging

A: With a 45 to 60 second cycle, four cavities typically deliver 240 to 320 cans per hour depending on wall thickness and cooling. We confirm the figure with your mould during the factory trial rather than quoting an ideal case.

A: Yes, cooling load rises with cavity count. We size the chiller with the machine and the mould, and we will tell you honestly when a four cavity mould needs a larger unit than the standard package.

A: They can run in pairs, but mixing moulds on one platen means both share a cycle time, which usually wastes capacity on the faster part. Plants that need two 20L designs generally run them in separate production blocks.

Die heads are crated individually with flow plates numbered, the machine packed in a fumigation-free export wooden case with steel reinforcement and VCI film. Delivery is 30 to 45 working days after deposit. ISO 9001:2015 certification, CE marking, 12 month warranty and on-site or remote commissioning are included.
