Applications
The PET 260 Ton is used where a preform or jar mould needs the most platen area, daylight and shot weight in the PET range. Very high cavity preform production also depends on the mould, hot runner and post-mould cooling, so discuss these with our engineers when sizing the machine.

FAQs / Buyer Questions
The answers our engineers give most often about the PET 260 Ton, before a specification is agreed.
What Is the PET 260 Ton Injection Moulding Machine?
It is a horizontal injection moulding machine from Pratishna Engineers for PET raw material, based on the C Series 260 Ton. It is the largest model in the PET range, built for the heaviest preforms and the highest-cavity moulds in the range.What PET Products Can I Mould on a 260 Ton Machine?
Typical PET work includes high-cavity bottle preform moulds, heavy preforms for large-volume water and edible oil containers and large wide-mouth jar preforms.How Do I Know if 260 Ton Is Enough for My Preform or PET Part?
Required clamping force depends on the projected area of all cavities, injection pressure and material, with a safety factor. For preform moulds, mould height, cavity pitch and hot runner size within the tie-bar space often decide the machine as much as clamping force. Share your preform or part drawing and mould details and Pratishna Engineers will confirm whether the PET 260 Ton is suitable.What Are the Screw Options on the PET 260 Ton?
The PET 260 Ton is available with two screws: the 55 mm screw gives a 513 g shot at up to 1,862 kg/cm² and 215 cc/sec; the 60 mm screw gives a 610 g shot at up to 1,564 kg/cm² and 256 cc/sec. Clamping, ejector and general specifications are common to all screw options. Shot weights are given for PS. PET is denser in the melt, so the same swept volume gives a heavier PET shot; the PET shot weight and the screw and barrel configuration for PET are confirmed for each enquiry.Why Must PET Be Dried Before Moulding?
PET absorbs moisture from the air. Moisture left in the granules breaks down the polymer in the barrel, lowering its intrinsic viscosity (IV) and giving brittle or hazy parts. PET is normally dried in a dehumidifying dryer to below about 50 ppm moisture before moulding, following the resin supplier’s drying conditions. A hopper dryer and loader is available as an optional feature.
What Mould Size Fits the PET 260 Ton?
The PET 260 Ton takes moulds 200 to 600 mm thick within a tie-bar space of 580 × 497 mm, on platens of 865 × 800 mm, with a 1050 mm daylight opening and 150 mm ejector stroke.If 260 Ton Is Not the Right Size, What Other Options Are There?
The PET range also offers 75 Ton, 100 Ton, 125 Ton, 150 Ton, 180 Ton and 220 Ton models. For other plastics, the same machine is available as the 260 Ton Horizontal Injection Moulding Machine (C Series).Does Pratishna Provide Installation and After-Sales Support?
Yes. Installation, commissioning, operator training, spare parts and after-sales technical support are provided as part of Pratishna’s machine lifecycle services.How Do I Get a Price for the PET 260 Ton?
Share your preform or part drawing, PET grade, part weight, mould dimensions, cavities, hot runner details, production quantity and cycle time, and Pratishna Engineers will evaluate the configuration and provide a quotation.
