High Performance Single Acting Plunger with CE for 250 Tons Hydraulic Hot Press Machine

Forged hydraulic plunger is the core transmission component in hydraulic systems. It converts hydraulic energy into mechanical energy by reciprocating within the hydraulic cylinder, thereby achieving force transmission and motion control.

Understanding


The High Performance Single Acting Plunger is a CE-certified hydraulic component designed exclusively for 250 Tons Hydraulic Hot Press Machine systems. Unlike double-acting plungers, its Single Acting Design relies on hydraulic pressure for one-way motion (e.g., downward pressing) and external force (e.g., spring or gravity) for return—ideal for cyclic hot-pressing processes. As a core part of hydraulic cylinders in hot press machines, it efficiently converts hydraulic energy into pressing force, ensuring stable performance under high-temperature conditions (common in hot-pressing operations). The CE Certification guarantees compliance with EU safety and quality standards, making it suitable for global markets.

Features


Built with Heat-Resistant Alloy Steel Forging to withstand high temperatures (up to 200°C) in hot press operations, preventing material deformation.

Equipped with CE Certification, ensuring adherence to EU safety regulations for mechanical components, suitable for export to European and global markets.

Features Single Acting Design that simplifies hydraulic circuit layout, reduces energy consumption, and improves cycle efficiency for hot-pressing tasks.

Undergoes High Frequency Surface Hardening to achieve HRC50-60 surface hardness, enhancing wear resistance against high-temperature friction.

Uses precision CNC Machining to ensure tight tolerance (±0.02mm), minimizing oil leakage and extending the service life of hydraulic cylinders.

Provides Customized Service for size, surface treatment, or hardness adjustments to match specific hot press applications (e.g., wood, metal, or composite materials).

Includes 100% UT/MT Inspection before delivery to eliminate internal or surface defects, ensuring reliability in continuous hot-pressing workflows.


Typical Uses


This CE-Certified Single Acting Plunger is widely used in the hydraulic cylinders of 250 Tons Hydraulic Hot Press Machines for:

Wood processing: Hot-pressing plywood, MDF, or veneer to enhance bonding strength.

Metal forming: Hot-stamping or shaping thin metal sheets for automotive parts or household appliances.

Composite material manufacturing: Pressing fiberglass or carbon fiber composites into structural components (e.g., wind turbine blades).

Rubber and plastic processing: Vulcanizing rubber products or molding thermoplastic parts under heat and pressure.


FAQ


What is the advantage of the Single Acting Design in a Hydraulic Hot Press Machine?

It reduces hydraulic system complexity (fewer valves and hoses) and energy use—only one hydraulic line is needed for pressing, while return is powered by gravity or springs, speeding up hot-press cycles.


Does this plunger meet EU safety standards?

Yes, it is CE Certified (compliant with EU EN 13920 and EN ISO 4413 standards), ensuring safe operation and eligibility for sale in the European Economic Area (EEA).


What is the size of this High Performance Single Acting Plunger?

The standard size is OD600*L900. For non-standard hot press cylinders, we offer Customized Service to adjust outer diameter (OD) and length (L) as needed.


How long is the warranty, and what does it cover?

It comes with a one-year warranty covering manufacturing defects (e.g., material cracks, surface peeling). It does not cover damage from improper installation or overloading beyond 250 tons.
