CORE CAPABILITIES

Six Capabilities Behind Every Hydraulic Cylinder Project

Engineering & Design

Application review, 2D and 3D drawings, material selection, mounting design, and technical confirmation.

CNC Machining

Turning, milling, drilling, threading, grinding, large-component machining, and precision interface production.

Barrel Processing

Honing, skiving and roller burnishing, bore control, straightness inspection, and surface-finish verification.

Welding & Fabrication

Qualified welding procedures, robotic or manual welding, inspection, and material traceability.

Assembly & Integration

Seal installation, cylinder assembly, cushioning, hydraulic valves, sensors, and accessories.

Testing & Documentation

Proof pressure testing, leakage inspection, certificates, inspection reports, and packing records.

ENGINEERING & DESIGN SUPPORT

Application-Based Cylinder Engineering

Engineering begins with the application—not with a standard cylinder catalog. Requirements are reviewed around load, pressure, stroke, mounting geometry, operating speed, duty cycle, hydraulic fluid, temperature, corrosion, and installation conditions.

PRECISION MANUFACTURING

CNC Machining and Cylinder Barrel Processing

Machining accuracy, surface finish, alignment, and dimensional consistency directly affect cylinder life and performance.

WELDING & FABRICATION

Controlled Welding for Structural Reliability

Welded joints, mounting ends, ports, trunnions, cross tubes, and fabricated structures are produced according to confirmed drawings and project requirements.

Procedure Control

WPS/PQR documentation and project-specific welding requirements.

Qualified Welders

Welder qualification records can be supplied when requested.

Inspection Support

Visual inspection, MT, LPI, UT, or third-party inspection as specified.

Traceability

Material, welding, and inspection records are linked to documentation.

ASSEMBLY & SYSTEM INTEGRATION

Assembly, Accessories, Valves and Sensors

Cylinder assembly is completed using confirmed seals, bearings, wear rings, ports, fasteners, valves, sensors, and other accessories required by the application.

Seal and wear-ring installation

Piston and gland assembly

Fixed or adjustable cushioning

Counterbalance valve, check valve, load-holding valve

Linear position sensor, proximity switch, pressure sensor

Final cleaning and preparation

SURFACE PROTECTION

Rod Treatments, Coatings and Corrosion Protection

Surface treatment is selected according to wear, corrosion, temperature, fluid, outdoor exposure, and expected service life.

Hard Chrome Plating

Common piston-rod protection for wear resistance and industrial service.

HVOF Coating

High-performance coating for demanding wear and corrosion environments.

Stainless Steel

Suitable for marine, washdown, chemical, and corrosion-sensitive applications.

Industrial Painting

Color, thickness, surface preparation, and coating system selected according to project requirements.

Marine Coating Systems

Multi-layer corrosion protection for offshore, coastal, and saltwater applications.

Black Oxide or Special Finish

Component-specific surface treatment for carbon-steel parts.

TEST & QUALITY CONTROL

Inspection and Testing Before Shipment

Testing requirements are confirmed according to the cylinder design, working pressure, specifications, and project documentation requirements.

Material Verification

Material grade, certificates and traceability when required.

Welding Inspection

Ensuring reliable weld quality through visual and non-destructive test.

Proof Pressure Test

Pressure held according to confirmed test requirements.

Dimensional Inspection

Critical dimensions, mounting interfaces and tolerances.

Surface & Coating Check

Rod surface, paint, coating thickness and visual condition.

Accessory Verification

Valves, sensors, ports and installed accessories.
