Injection Molding Machine Ejection Hydraulic Cylinder 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 injection molding machine ejection hydraulic cylinder function: drives the injection platform to move.

Installation with earrings at both ends
Excavator boom hydraulic cylinder
MAPKER, Parker oil seal, Japanese NOK, Swedish SKF, equivalent brands, customer-specified brands are accepted.
1. The hydraulic cylinder of the excavator, the cylinder head and the cylinder cover are made of rolled steel and cast iron, and can also be processed according to the material specified by the customer.
2. The cylinder barrel is made of seamless steel pipe by grinding. The inner hole reaches a higher degree of finish, reduces internal friction, and extends the service life of the seal.
3. Each batch of purchased materials has a material inspection report, and its material and material properties are strictly in accordance with customer requirements.
4. The piston rod is generally made of high-strength steel, which makes the piston rod resistant to wear and corrosion. Stainless steel piston rods are usually used in specific environments, and can be chrome-plated to resist wear.
5. The guide sleeve is used to support the forward and backward movement of the piston rod. It is mostly made of ductile iron and can usually be removed without disassembling the entire cylinder.
6. Seals are generally made of nitrile rubber, grain rings, polyurethane, fluororubber or filled polytetrafluoroethylene (PTFE).
7. O-rings are used for static seals such as cylinder and guide sleeve, piston and rod, and Y-seal, V-seal or combined seal is used between piston and piston rod.
