What the cylinder does

The SUN-series boosting cylinder from Chen Sound is a pneumatic-hydraulic intensifier — a cylinder that uses ordinary compressed air as the input medium and converts it into a hydraulic output force an order of magnitude higher.

The principle works by air pushing on the large area of the primary piston, which moves a secondary piston with a much smaller area — this multiplies the force by the ratio of the piston areas. The output is a short but high-energy stroke, ideal for clamping workpieces, gripping fixtures or pressing operations.

The 3000 kg / 13 mm version means an output force of 3 000 kg (≈ 30 kN) at a stroke of 13 mm. The main advantage over pure hydraulics is the simplicity of installation — all you need is a compressed-air supply, no hydraulic pump or power unit.

Where the cylinder is found

The SUN boosting cylinder is used as a clamping element for CNC machines and milling fixtures, as well as for pressing operations and in automation lines. It is ideal where a compressed-air supply is available but a high gripping force is needed without having to install a separate hydraulic station. It is compatible with common clamping systems in CNC machining and can be deployed universally in shops running machines of various brands.
