Jars and pots demand two things at once: a wide, flat body and a clean, sturdy seam where the lid seats. A double station HDPE blow molding machine answers both, because two mould platens share one extrusion head, letting a filled cycle overlap with an open one. In a double station HDPE blow molding machine, the platen moves on a toggle mechanism along a linear guide, so motion is fast and smooth and the clamp holds its pressure through the whole cooling window. For 500 ml to 10 L jars, that steadier clamping keeps wall thickness even around the rim, where lids must seal.
Because both stations run from a single head, output rises without a second extruder. A converter running a double station HDPE blow molding machine for plastic jars gets close to double the parts per hour of a single-station machine at a fraction of the extra footprint and power draw, and the layout still fits a standard hall.
Built for Jars and Pots
The engineering priority here is seam quality and cycle overlap. A wide rim needs uniform clamp pressure to avoid thin spots that leak, and a jar body needs stable parison support so the base does not sag. The toggle-plus-guide design gives both, and the 200 kN clamp is enough to hold large cavities without flashing a soft PE shot. Because the oil tank is removable and portable, hydraulic service is a quick job rather than a long shutdown.
- Double station clamping: the defining trait of this double station HDPE blow molding machine.
- Toggle plus linear guide: quick, stable platen travel for consistent seams.
- Wide mould size: up to 700 x 420 mm suits large jar bodies.
- 200 kN clamp: enough force to hold big cavities without flashing.
- Removable oil tank: simple hydraulic service.

Applications
Cosmetic cream jars, food storage pots and industrial 1-10 L tubs are typical. The machine also handles wide-mouth containers for agrochemicals and paints, where a deep, even body and a precise thread are both required, and it can be paired with in-mould labelling when a jar carries a printed wrap.
Product Q&A
Q: Two stations from one head - does output really double?
A: Output rises because filling and cooling overlap, keeping the extruder busy far more of the cycle.
Q: Is clamping strong enough for large jars?
A: Yes, the 200 kN clamp and 700 x 420 mm platens hold big cavities firmly.
Q: How is maintenance handled?
A: A removable, portable oil tank makes hydraulic service quick on the double station HDPE blow molding machine.
