FAQs / Buyer Questions
The answers our engineers give most often about the 180 Ton, before a specification is agreed.
What Is the C Series 180 Ton Injection Moulding Machine?
It is a horizontal plastic injection moulding machine from Pratishna Engineers, built for closures, cups, small tubs and thin-wall food containers.What Can I Manufacture on a 180 Ton Container Machine?
Typical products include thin-wall food containers and lids, dairy and dessert cups, small iml tubs, jerry-can caps and bottle closures and sweet boxes.How Do I Know if 180 Ton Is Enough for My Container?
Required clamping force depends on the projected area of all cavities, wall thickness, flow length and material, with a safety factor. Thin-wall parts need more pressure and clamp margin than their weight suggests. Share your container and mould details and Pratishna Engineers will confirm whether the 180 Ton is suitable.What Are the Screw Options on the C Series 180 Ton?
The 180 Ton is available with two screws: the 40 mm screw gives a 249 g shot at up to 2,250 kg/cm² and 111 cc/sec; the 45 mm screw gives a 315 g shot at up to 1,778 kg/cm² and 140 cc/sec. Clamping, ejector and general specifications are common to all screw options.What Mould Size Fits the 180 Ton?
The 180 Ton takes moulds 200 to 500 mm thick within a tie-bar space of 480 × 424 mm, on platens of 725 × 650 mm, with a 875 mm daylight opening and 110 mm ejector stroke.
What Plastic Materials Can the 180 Ton Machine Process?
Depending on configuration, it can process PP copolymer, high-flow PP, HDPE, LDPE, PS and other thermoplastics used in packaging, as well as engineering plastics.If 180 Ton Is Not the Right Size, What Other Options Are There?
The C Series also offers 140 Ton, 220 Ton, 260 Ton and 320 Ton models. Larger pails and containers can move to the PHM Series two platen machines, and smaller parts to the E 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 C Series 180 Ton?
Share your container drawing, material, part weight, mould dimensions, cavities, production quantity and cycle time, and Pratishna Engineers will evaluate the configuration and provide a quotation.
