Horizontal Injection Moulding Machine (E Series)
The E Series is a range of horizontal plastic injection moulding machines from Pratishna Engineers, built for production moulding of small and medium plastic components. The series spans 75 to 180 tons across six models, each with two or three screw options, so manufacturers can match clamping force and injection capacity to the specific component and mould.
Pratishna Engineers is one of the top and trusted E Series horizontal injection moulding machine manufacturers in India. The Mumbai-based company has 35+ years of experience and has supplied 9,000+ machines to 1,000+ customers, offering the E Series for small and medium parts across household, electrical, packaging, automotive and agricultural applications, backed by in-house engineering and after-sales support.
Across the range, screw diameters run from 27 to 45 mm, shot weights from 82 to 315 g (PS) and injection pressure up to 2,645 kg/cm², with daylight openings from 625 to 900 mm and platens from 550 × 510 mm to 725 × 650 mm. Buyers should select a model by clamping force, shot weight, screw diameter, injection pressure, mould dimensions, cycle time, material and production volume, not tonnage alone.

The answers our engineers give most often, before an E Series specification is agreed.
What Is the Pratishna E Series Horizontal Injection Moulding Machine?
The E Series is a range of horizontal plastic injection moulding machines from Pratishna Engineers, available from 75 to 180 tons across six models, designed for small and medium plastic components.What Clamping-Force Range Does the E Series Cover?
The E Series covers six models: 75, 100, 125, 150, 165 and 180 tons.Which E Series Model Is Suitable for My Product?
The suitable model depends on your projected area, required clamping force, shot weight, mould dimensions, number of cavities and production volume. Share these details and Pratishna Engineers will recommend an appropriate model.Why Does Each E Series Model Offer Two or Three Screws?
A smaller screw gives higher injection pressure for thin walls and long flow paths, while a larger screw gives more shot weight. On the E-75, for example, the 27 mm screw reaches 2,500 kg/cm² with an 82 g shot, and the 32 mm screw gives a 116 g shot at 1,780 kg/cm².
What Products Can Be Manufactured on E Series Machines?
E Series machines are used for household products, electrical and electronic parts, packaging components, closures, small automotive parts, agricultural and irrigation parts and general industrial plastic components.What Plastic Materials Can the E Series Process?
Depending on the machine configuration, the E Series can process thermoplastics such as PP, PE, ABS, PS, nylon, PC, POM and other engineering plastics. Material-specific screw and barrel requirements should be evaluated before selection.What Is the Difference Between the E, C and H Series?
The E Series (75 to 180 tons) suits small and medium parts. The C Series (140 to 320 tons) is built for container making and thin-wall packaging, and the H Series (120 to 350 tons) is built for household articles and larger parts.Does Pratishna Provide Installation and Support for E Series Machines?
Yes. Pratishna Engineers provides installation, commissioning, operator training and after-sales technical support, along with spare parts, as part of its machine lifecycle services.
