ENGEL ES 1350H200W/300HL-2F — 2K Injection Moulding Machine

This machine from the prestigious Austrian manufacturer ENGEL, built in 2001, features a clamping force of 300 tonnes and a true 2K L-configuration in horizontal layout.

Motor and Hydraulic System

The machine is equipped with a powerful electric motor coupled to a high-pressure hydraulic pump group. The electric motor continuously drives the hydraulic pump, providing pressurised oil flow throughout the entire system. This pressurised oil feeds the clamping cylinder, the injection pistons of both units, and the ejector system. The thick red hydraulic hoses visible behind Unit B carry this high-pressure oil flow — both units are supplied via independent hydraulic circuits, allowing Unit A and Unit B to operate simultaneously without influencing each other.

Operating Principle

The two independent injection units are positioned at 90° to each other — in an L-shape. The mould is locked with 300 tonnes of clamping force. Unit A injects the primary material into the mould at 1834 bar. Immediately afterwards, Unit B injects the second material or colour from a 90° angle into the same mould at 1620 bar. The two materials bond at a molecular level inside the mould, cooling is completed and the ejectors push out the finished 2K part as a single piece. No gluing, screwing or assembly is required — two materials emerge as one single part in a single cycle.
