80mm Screw Blow Moulding Machine for 5L to 100L HDPE Drums and Barrels

Screw diameter is the single number that decides how large a parison a machine can feed. At 70 mm a plant is limited to small and medium containers; at 80 mm with a 25:1 L/D barrel the MP100FD pushes 120 to 150 kg/h of HDPE and can hang a parison heavy enough for a 100 litre drum.

The barrel is nitrided rather than simply hardened, which matters when a machine runs abrasive grades or regrind. Nitriding resists the wear that quietly opens up the clearance between screw and barrel over a few years, and that clearance is what turns a stable parison into an unstable one.

• 80 mm nitrided screw: 25:1 L/D geometry gives thorough plasticizing and resists wear from regrind and filled grades
• 120-150 kg/h HDPE output: Enough melt volume to feed a large accumulator head without waiting between shots
• Four to six heating zones: Independent barrel zones let the profile be tuned from feed to metering section
• 5L to 100L working range: One screw and one frame cover the full container size span buyers usually need
• Multi die head ready: Single, double or four head configurations bolt to the same extruder
• Closed loop water cooling: Dedicated chiller circuit keeps barrel and mould temperatures stable through the shift

• 5L to 20L jerry cans for lubricants and chemicals
• 25L to 60L drums for agrochemical concentrates
• 60L to 100L tight head and open top drums
• Large blow moulded toys and sports equipment
• Automotive ducts and washer fluid reservoirs

A: Nitrided screws handle clean regrind well, and most buyers run 20 to 30 percent regrind in the middle of the wall. For heavy regrind with abrasive fillers we recommend a bimetallic barrel, which we can quote as an option at order stage.

A: The frame will physically run a 5 litre part, but a 100L machine has a long cooling cycle compared with a dedicated small machine. Plants running mostly small parts usually take a smaller frame; we advise on the split before quoting.

A: Four to six zones run from feed to metering, with the die head zones set separately. Our technician records the profile during commissioning with your material and hands over a written sheet, so your team is not guessing on the first material change.

Each unit is packed in a fumigation-free export wooden case with steel reinforcement, moisture barrier film and VCI protection. Standard delivery is 30 to 45 working days after deposit. ISO 9001:2015 and CE certification are supplied with the machine, together with a 48 hour pre-delivery dry run report, a 12 month warranty and on-site or remote installation guidance.
