Boom Cylinder of Excavator is a very important part of the injection molding machine. When the injection is completed and the mold is opened, the ejector hydraulic cylinder pushes the ejector rod or ejector block through the hydraulic force to eject the injection molded product from the mold cavity, making it easier to take out the product.

The material of the T2A hydraulic cylinder relief valve block; Q355D forged, 20# steel, GGG50, etc. Each piece is subjected to flaw detection testing to prevent oil leakage and oil channeling in the hydraulic valve block.

Crane counterweight hydraulic cylinder is an important device that realizes crane balance through hydraulic transmission mechanism. It is mainly composed of cylinder body, piston, piston rod, sealing element, oil filter, hydraulic pipeline and oil tank. The working principle is based on Pascal's law, that is, in a closed container, pressure is transmitted to every point in the liquid, and the pressure acting on the liquid is proportional to the area. When the crane is lifting, the hydraulic pump presses the oil into the cylinder, causing the piston to rise, thereby increasing the hook height. When the load of the crane increases, the oil inside the cylinder will be compressed and the piston will drop, thus achieving the balance of the crane.

China Model 28600 High Precision Tool Vises
