Product introduction
Hydro-cylinder is the main component on engineering machinery; many actions are taken by it. It is a hydraulic actuator, which is doing straight reciprocating motion to transfer the hydraulic energy into mechanical energy. It has a simple structure and runs reliably to do reciprocating motion without reduction gear, and without transmission interval. Therefore, it is widely used at all kinds of hydraulic systems.
Our main material for the Hydro-cylinder is similar to followings:
Advantage
1. Stable property 
Shanghai Special Metal Co., Ltd produces high quality hydro-cylinder with good leakproofness to keep its power stable.
2. Simple process, friendly-environment
Air is in endless supply from medium view, easy to get supplied; it is convenient to use it. And it is friendly-environment.
3. Small air viscosity
 Production Process 
1. Wooden pattern Production  
2. Molding
