FORGE-P-OD500*L4000
ETERNAL
A Heavy Duty Hydraulic Plunger is a precision-engineered transmission part that operates within hydraulic cylinders. Unlike standard plungers, it is built to withstand extreme pressure, repeated reciprocation, and harsh working conditions—critical for forging press machines that shape metal through high-force compression. ETERNAL's plunger stands out for its robust construction, which ensures minimal wear, long service life, and consistent performance in even the most demanding industrial settings.
Our plunger is not just a component; it's a reliability-driven solution. Crafted from high-grade alloy steel forging material, it undergoes strict quality control—including 100% UT/MT inspection before shipment—to eliminate defects. This focus on quality makes it a top choice for manufacturers seeking to reduce downtime and maintain operational efficiency in their hydraulic press machine systems.
Alloy Steel Forging: The plunger is made from premium alloy steel, selected for its exceptional strength, hardness, and wear resistance. This material ensures the plunger can handle the high impact and pressure of forging press machine operations without deformation.
Quenching and Tempering: Every unit undergoes a precise heat treatment process—normalizing followed by quenching and tempering—to enhance mechanical properties. This step boosts toughness while maintaining rigidity, a key requirement for heavy-duty applications.
To further improve durability, the plunger features multiple surface treatment options:
Surface Quenching: Creates a hardened outer layer (HRC 50-60) with a quenched depth of 2-4mm, enhancing resistance to abrasion and corrosion.
Electroplating: A 20-50μm electroplated layer adds an extra barrier against wear, ideal for environments with frequent friction.
Stainless Steel Overlay Welding: For maximum protection, 2Cr13-4Cr13 stainless steel overlay welding is available—perfect for clients needing resistance to harsh chemicals or extreme temperatures.
CNC Machining: Each plunger is crafted using CNC machining and surface grinding, ensuring dimensional accuracy and smooth operation within hydraulic cylinders.
100% Inspection: Before delivery, all plungers undergo UT (Ultrasonic Testing) and MT (Magnetic Particle Testing) to detect hidden flaws—guaranteeing compliance with international industrial standards.
The plunger is specifically designed for hydraulic cylinders of forging press machines. It enables these machines to generate the high force needed to shape metal components—such as automotive parts, industrial gears, and construction hardware—by converting hydraulic pressure into linear motion. Its durability ensures consistent performance even during long production runs.
Beyond forging presses, ETERNAL’s plunger is also compatible with other high-pressure systems, including:
Hydraulic press machines for metal stamping and forming.
Cold chamber die casting machines for high-speed, high-pressure metal casting.
Extrusion press machines for aluminum and steel extrusion.

ETERNAL offers customized hydraulic plunger solutions to match specific client requirements. Whether you need a different size, alternative surface treatment (e.g., specialized coatings), or modified material grades, our engineering team works closely with you to deliver a product that fits your hydraulic press machine or forging equipment perfectly.
Our plunger combines three key advantages: premium alloy steel forging material, advanced heat and surface treatments, and 100% pre-shipment inspection. This trio ensures superior durability, longer service life, and fewer maintenance issues compared to standard plungers—critical for minimizing downtime in heavy industries.
Yes. The quenching and tempering heat treatment process enhances the plunger’s heat resistance, making it suitable for high-temperature settings (e.g., hot forging press machines). For extreme heat applications, we also offer optional stainless steel overlay welding to further boost thermal stability.
The 1-year warranty covers any manufacturing defects, and our team provides after-sales support to help extend the product’s lifespan.
Absolutely. We regularly export our Heavy Duty Hydraulic Plunger for Forging Press Machine to Egypt, Russia, Europe, and Southeast Asia. Our shipping process includes secure steel pallet packaging and compliance with international import regulations, ensuring timely delivery and hassle-free customs clearance.
