From Concept to Drawing
Each hydraulic cylinder starts with a detailed 2D or 3D drawing to ensure precision in every stage of production.
①
Define Working Conditions
Determine the working pressure and required stroke based on the actual application.
②
Select Main Dimensions
Decide the inner diameter of the cylinder barrel and the piston rod diameter.
③
Calculate Structural Parameters
Calculate wall thickness and outer diameter to ensure strength and safety.
④
Design Cylinder Head and Guide Sleeve
Determine the thickness of the cylinder head and the minimum guide sleeve length.
⑤
Determine Cylinder Barrel Length
Define the total barrel length according to the stroke and mounting type.
⑥
Check Piston Rod Stability
Perform stability verification to ensure reliable operation under working load.
