The Pneumatic Cylinder for PET Bottle Blowing Machines is a high-performance, high-pressure actuator specifically designed to withstand the rapid cycling and intense force requirements of the PET preform blowing process. Engineered for precision, durability, and speed, this cylinder plays a vital role in functions like mold opening/closing, stretching, and pre-blow or final blow operations during the bottle forming cycle.

Built with hardened chrome-plated steel piston rods, hard-anodized aluminum or high-strength steel tubes, and high-pressure seals, these cylinders deliver consistent, high-speed actuation under operating pressures of up to 40 bar. The result is reliable and repeatable motion performance—critical for maintaining quality and efficiency in fully or semi-automatic bottle blowing machines.

The design includes adjustable cushioning, magnetic pistons for sensor-based stroke monitoring, and compatibility with various mounting styles, allowing seamless integration with machines from different OEMs. Designed for long life and minimal maintenance, these cylinders are widely used in the packaging, beverage, and plastic industries for producing PET bottles of various shapes and volumes.
