Hydraulic Power Unit for Presses and Extrusion Lines

Extrusion lines require hydraulic systems capable of working with force, continuity and control. In applications dedicated to processing aluminium, copper, brass and special alloys, the hydraulic power unit is not a simple power pack: it is a fundamental part of the machine’s performance.

This CMH hydraulic power unit was engineered for industrial applications in the extrusion sector, where work cycles can be prolonged and where system stability is essential to ensure repeatable movements, control of the functions and operational reliability.

One of the main features of the system is the management of work continuity. During machine operation, the oil must maintain suitable temperature and cleanliness conditions, avoiding drift that can compromise performance, precision and component life. For this reason the power unit integrates a heat exchanger, useful for stabilising the oil temperature even under intensive cycles.

The layout of the power unit was developed considering the available space, the position of the components, ease of connection to the machine and maintenance needs. The motor-pump group, valve blocks, piping, reservoir and cooling system are integrated into a compact, robust solution.

In the extrusion sector, hydraulic control must meet precise requirements: feeding the machine’s services, managing pressures and flows, ensuring stability during the cycle and supporting the continuous work of the production system.

CMH designs and builds custom hydraulic power units for industrial machines, always starting from the real function of the application. Every system is developed according to flow, pressure, work cycle, operating environment and the requirements of the final machine.

Designed, built and tested in Italy, this power unit is a concrete example of hydraulics applied to industrial production: power, control and continuity at the service of the machine.
