Hydraulic Booster Cylinder
The hydraulic booster cylinder is a device that converts low-pressure hydraulic input into high-pressure hydraulic output by utilizing the piston area ratio principle. The boosting function is completed within an integrated cylinder body. Users only need to supply a low-pressure hydraulic source to obtain several to dozens of times higher pressure output.

Compared with traditional hydraulic systems, hydraulic booster cylinders do not require large hydraulic power units, thereby saving installation space, reducing costs, and improving safety. They are particularly suitable for workstations where localized high pressure is required.

Key Features
• Equipped with a built-in hydraulic sequence valve. With its pre-pressurization characteristic, the working cylinder can be fully filled with oil, and when the sequence valve is triggered at the preset pressure, the system automatically switches to boosted pressure.
• High-pressure output: Delivers several to dozens of times higher hydraulic pressure from low-pressure input.
• Integrated design: Built-in boosting mechanism, no external hydraulic source required.
• Compact structure: Ideal for installation in limited workspaces and fixtures.
• Cost saving: Replaces the combination of conventional hydraulic pumps and cylinders.
• Easy maintenance: Only requires inspection of oil level and sealing components.

Applications
Suitable for hydraulic special-purpose machines and in low-pressure circuits of machining center (MC) fixtures. When certain cylinders require high-pressure operation, the HB booster can be operated with just one solenoid valve or connected in the pipeline. It automatically converts low hydraulic pressure into high hydraulic pressure for strong clamping.

Hydraulic booster cylinders are commonly used in processes that require intermittent or localized high pressure, such as:
• CNC machining fixtures: Provides stable clamping force to prevent workpiece displacement caused by cutting forces or vibration.
• Stamping and forming stations: Small-scale pressing, punching, and riveting operations.
• Automated production lines: Provides high pressure for individual workstations without requiring a full system high pressure supply.
• Pressure testing equipment: For sealing tests and endurance pressure checks.
• Electronics and automotive parts assembly: Provides high-pressure clamping or pressing during precision component assembly.
