Four Head Blow Molding Equipment for Multi Cavity Bottle Output

Cavity count is the cheapest capacity a bottle plant can buy. The MP80D accepts one, two, three or four die heads on the same machine body, so output scales in steps without adding floor space, operators or another electrical connection.

The practical benefit shows up in quoting. A plant that owns a four head capable machine can quote a private label order at four cavities and a low volume specialist order at one cavity, using the same frame and the same team, instead of turning work away or over-committing a large line.

• One to four die heads: Output scales in steps on the same frame, from single cavity prototypes to four cavity production
• Multi cavity mould support: Four parisons per cycle for small and medium bottles where cavity count drives unit cost
• Independent head adjustment: Each head is trimmed separately so cavity weights stay close across the platen
• 80 mm screw supply: 90 kg/h HDPE output keeps four heads fed without starved parisons at full cycle speed
• Recipe per configuration: Settings for each head count stored and recalled, so a change of setup is not a re-tune
• 150 kN clamping: Holds the parting line on four cavities simultaneously on the 520 x 460 mm platen

• Multi cavity 500 ml to 2L detergent bottles
• Four cavity shampoo and lotion production
• Small chemical bottles in the 250 ml to 1L range
• Private label packaging runs with high cavity counts
• Contract moulding where unit cost decides the order

A: Roughly proportional to the head count, provided cooling capacity and cycle time keep pace. On a 1 litre bottle a four head setup typically returns three to four times the single head rate; we confirm the real figure with your mould at the factory trial.

A: Yes, and that is the usual path. The body and PLC support four heads, so additional heads and moulds are added when volume justifies it, without replacing the machine.

A: Only if the flow channels are unbalanced. Each head on this machine is adjusted independently, and we record cavity weights during pre-delivery testing so the buyer receives the variation data rather than a promise.

Die heads ship crated individually with flow components wrapped and numbered, and the machine travels in an export wooden case with steel reinforcement and anti-rust film. Delivery is 25 to 35 working days after deposit. CE marking, ISO9001:2008 records, English documentation and a 12 month warranty are included, with commissioning support on request.
