The cylinder tubes are machined, polished to mirror finish and electro less nickel plated internally in order to reduce surface roughness to the lowest value and to provide highest protection against corrosion and low maintenance.
For pneumatic actuators the sealing with flanges and piston is performed by means of a floating O-ring design and guided internally by a sliding ring in Teflon graphite.
For hydraulic actuators the sealing with flanges and piston is performed by means of O-rings and guided internally by a sliding ring in Teflon bronze.
All seals are specifically designed and chosen on the basis of the use cases: ambient temperature, supply medium type, etc.
Pneumatic cylinders (supply medium can be air or gas) are suitable for supply pressures up to 160 bar.
Hydraulic cylinders are suitable for supply pressures up to 400 bar.
The springs are fully encapsulated in a welded container, which encloses the spring assembly in a safety frame arrangement that does not allow it to extend beyond a given value and ensures personnel safety.
Quality control has top priority throughout all stages of design and manufacturing. Each phase of the process is executed according to defined policies necessary to guarantee that the final product exceeds the customers’ expectations and has an increased reliability.
Any arisen non conformities are thoroughly checked and any reasons which have caused the non-conformity are removed by the implementation of the necessary corrective actions.
In order to protect from corrosion, before the assembly each actuator’s component is individually degreased, phosphate cleaned & treated, shot-blasted and epoxy primer coated.
