ETERNAL

Product Description

Our ceramic press forging hydraulic cylinder is a high-pressure, long-life, high-precision actuator for ceramic powder dry pressing,which can be installed in hydraulic presses of mainstream brands such as Keda, SACMI, System, SITI B&T. The core uses forgings+heat treatment+hard surface+high-pressure sealing, suitable for 25-40MPa, large tonnage (500-6000t) presses, and the main cylinder is mostly plunger type.

Detailed Paremeter

2.Cylinder barrel heat treatment:	Normalizing
3.Plunger heat treatment:	quenching and tempering
4.Hardness of plunger:	HB200-250
5.Surface hardness of plunger:	HRC53-58
6.Surface treatment of plunger	Surface quenching; chrome plating
7.Thickness of the chrome plating layer	0.02mm
8.Hydraulic cylinder max work pressure:	31.5MPA
9.Hydraulic cylinder max thrust:	1500 tons
10.We choose suitable seal ring kits. Seal ring brands include: Parker, Merkel, NOK, Guangzhou Rubber institute, Taiwan brand etc.
11.The welding on cylinder tube and flange would be Ultrasonic tested every time.The welding seam would be cleaned before machining.We ensure that every welding seam has no any leak during lifetime.
12.Carry out 100% pressure testing without any leak before shippment.

Application

We specialize in producing forging heavy-duty hydraulic cylinders specifically for ceramic presses, which are fully compatible and interchangeable with international mainstream brands such as Keda, SACMI, System, SITI B&T ceramic hydraulic presses.

Architectural ceramics: wall and floor tiles, permeable bricks, ceramic panels, etc

Industrial ceramics: alumina ceramics, zirconia ceramics, etc

Electronic ceramics: ceramic capacitors, resistors, insulators, etc

Product Procedure

Material Selection & Blanking: Adopt high-pressure steel such as 42CrMo.
Forging Blanking: Heat steel billets and forge into cylinder barrel and piston rod blanks, then pass flaw detection.
Heat Treatment: Quenching and tempering to ensure sufficient strength, toughness and qualified hardness.
Precision Machining
Cylinder barrel: Rough & fine boring → rolling/honing → thread and oil port turning.

Plunger: Rough turning → quenching and tempering → precision grinding → chrome plating/nickel-based coating.
Surface Treatment: Implement anti-rust treatment for cylinder barrels and hard chrome/anti-corrosion coating for piston rods to enhance wear and corrosion resistance.
Component Assembly: Clean parts → install seals → connect piston and piston rod → assemble into cylinder barrel → fit end caps and guide sleeves.

Pressure Test & Inspection: Hold pressure at 1.25~1.5 times the rated pressure to check internal and external leakage, stroke and buffering performance.
Finished Product Coating: Spray paint for rust prevention, ship after passing inspection.
