Key Features
- Hydro-mechanical locking with balanced clamping force across the mould face, which reduces corner flash on large parts
- Clamping stroke of 1000 mm and 1225 mm daylight opening for deep moulds 225 to 645 mm thick
- Two screw options: the 45 mm screw reaches 2,323 kg/cm² and the 50 mm screw gives shots up to 424 g (PS)
- Tie-bar space of 460 × 440 mm and platens of 800 × 815 mm
- Hydraulic ejector with 150 mm stroke and 7.5 tons force
- Servo-driven pump of 24.1 kW and much less oil than a ram or direct-lock machine
- Moving platen on a linear motion guide, and Vignan SV 84 controller with 150 mould programs
Applications
The PHM 160 Ton is commonly used for buckets, storage boxes and deep parts where a toggle machine of similar tonnage cannot open far enough.

FAQs / Buyer Questions
The answers our engineers give most often about the PHM 160 Ton, before a specification is agreed.
What Is the PHM 160 Ton Two Platen Injection Moulding Machine?
It is a hydro-mechanical two platen injection moulding machine from Pratishna Engineers, the entry model of the PHM Series, built for buckets, crates, storage boxes and other deep or large parts that need a long opening stroke.What Can I Manufacture on a 160 Ton Two Platen Machine?
Typical parts include buckets and pails, storage boxes with lids, small crates and bins, casseroles and large houseware and battery covers and small containers.Why Choose a Two Platen Machine Instead of a Toggle Machine at 160 Tons?
The PHM 160 Ton opens 1000 mm with 1225 mm daylight, so deep parts such as buckets and bins can be released, while the machine stays shorter than a toggle machine of similar tonnage. Clamping force is applied at the tie bars, which keeps large flat moulds closed evenly.What Are the Screw Options on the PHM 160 Ton?
The 160 Ton is available with two screws: the 45 mm screw gives a 343 g shot at up to 2,323 kg/cm² and 143 cc/sec; the 50 mm screw gives a 424 g shot at up to 1,882 kg/cm² and 177 cc/sec. Clamping, ejector and general specifications are common to both.What Mould Size Fits the PHM 160 Ton?
It takes moulds 225 to 645 mm thick within a tie-bar space of 460 × 440 mm, on platens of 800 × 815 mm, with a 1000 mm stroke and 150 mm ejector stroke.
Can the Clamping Force or Opening Stroke Be Increased?
Yes. Clamp force and opening stroke can be increased on demand for applications that need more than the standard specification, subject to evaluation of the mould and part.If 160 Ton Is Not the Right Size, What Other Options Are There?
The PHM Series also offers 200 Ton, 250 Ton and 350 Ton models. Smaller parts can move to the H or C Series horizontal machines.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 PHM 160 Ton?
Share your product drawing, material, part weight, mould dimensions and height, cavities, production quantity and cycle time, and Pratishna Engineers will evaluate the configuration and provide a quotation.
