High Strength Forged Cylinder for Hydraulic Press Piston Applications

High Strength Forged Cylinder for Hydraulic Press Piston Applications

Our High Strength Forged Cylinder is precision-engineered for use in hydraulic press piston systems, ensuring outstanding reliability and durability under extreme operating conditions. Manufactured from premium alloy steel through advanced open-die forging and heat treatment processes, this cylinder provides superior tensile strength, excellent impact resistance, and uniform internal structure.

Key features include:

• Exceptional fatigue resistance for long service life in high-pressure environments.

• Enhanced dimensional stability achieved through precision machining and controlled heat treatment.

• Optimized grain flow ensuring consistent mechanical performance and reduced risk of failure.

Applications:
This forged cylinder is widely used in hydraulic presses, heavy-duty forming machines, metallurgical equipment, construction machinery, and marine hydraulic systems, where high compressive load and wear resistance are essential for safe and efficient operation.

Forged Steel Manufacturing Process:

Raw material verification → Precision cutting to required size → Controlled preheating under uniform temperature → Open-die or closed-die forging to specified geometry → Normalizing and heat treatment for grain refinement → Visual and dimensional inspection of forged blanks → Rough machining for shape accuracy → Non-destructive testing (UT, MT) and dimensional measurement → Quenching and tempering for enhanced strength and toughness → Final inspection of mechanical and surface quality → Finish machining to drawing tolerance → Dimensional verification and marking → Anti-rust coating, protective packaging, warehousing, and shipment.

Frequently Asked Questions (FAQs)

1. What is the weight capacity of your forgings?
We manufacture forged parts ranging from approximately 100 kg to 7,000 kg, covering both medium-size and heavy-duty applications across various industrial sectors.

2. Do you provide heat treatment and machining services?
Yes. Our in-house heat treatment facilities allow precise control of mechanical properties, and we offer components in as-forged, rough-machined, or fully finished conditions based on customer requirements.

3. Which industries commonly use your forged products?
Our forgings are widely applied in wind power generation, heavy construction equipment, port cranes, mining machinery, and power transmission systems, where reliability and high load performance are critical.

4. What is the typical production lead time?

• Standard materials in stock: around 30 days after order confirmation.

• Custom alloys or special-size forgings: usually 40–45 days, depending on weight, dimensions, and machining complexity.

5. Where is your production facility located?
Our manufacturing base is situated in Changzhou, Jiangsu Province, approximately two hours from Shanghai, with convenient access to Shanghai Port for global export logistics.
