Steel Custom Hydraulic Cylinder Single Action For EVA Foam Sheet Moulding Hot Press

Name:Custom Made Single Action Cylinder for Single Daylight / Multi Daylights EVA Foam Sheet Moulding hot press​

EVA Foam Sheet Moulding hot presses shall need heavy, robust press frames with height heavy fabricated side columns.The hydraulic cylinder for EVA Foam Sheet Moulding has been highly required on the quality,and these cylinders are designed for at least 50 years usage,so we have the robust cylinder body thickness -120mm,and all the parts are made from steel C45/42CrMo forged and Ultrosand testing passed and stress relief:

Cylinder body:1045/42CrMo one piece forged steel or welded forged steel with stress relief with full UT tested

Piston:C45/42CrMo forged steel rod with heat treatment and surface hard chrome plating with surface RA 0.4 and hardness HRC 45

Seal:German brand or Parker

Guide sleeve:Brass
