At CLAMPWELL COMPANY LTD., we design every Clamping Cylinder with one goal in mind—empowering industrial buyers who seek dependable precision and long-term stability in modern machining environments. Since our early years, our team has been committed to advancing the performance level of clamping technologies by integrating engineering knowledge gained from decades of supporting global CNC system requirements. What began as a focus on distributing European and American clamping mechanisms gradually evolved into an in-house development roadmap that allowed us to build stronger, more adaptable systems for customers who rely on predictable positioning, consistent pressure behavior, and dependable holding strength under demanding conditions. As machine tools advanced, we extended our capabilities to produce pneumatic and hydraulic solutions, ensuring that our product range gives importers, wholesalers, and large-scale operators the performance flexibility they expect. Today, our portfolio supports long-term production reliability for every buyer seeking durable fixture components sourced from a trusted manufacturer in Taiwan.
Our engineering teams continue to refine structural rigidity, sealing integrity, and operational smoothness across a wide range of applications, particularly as machining centers increase in speed and tolerance expectations. Through ongoing material improvements and performance testing, we create cylinders engineered for stable clamping force throughout high-load operations. Each unit is structured to maintain balanced pressure distribution, optimized piston movement, and long service life even under repetitive cycles. As part of our long-term development strategy, we also integrate system compatibility features that allow our cylinders to operate smoothly with a Hydraulic Pump, helping users achieve reliable responsiveness, consistent pressure buildup, and enhanced positioning accuracy across intensive production cycles. Our customers benefit from solutions built on decades of accumulated knowledge—solutions that align with operational requirements for automated fixtures, modular tooling systems, and precision-driven manufacturing workflows. And because global buyers increasingly prioritize products from trustworthy suppliers with international experience, we emphasize innovation, structural diversity, and sustainable performance in every design to ensure dependable results for expanding production lines.

Hydraulic Pump
Air Drive Hydraulic Power Unit
A air drive hydraulic power unit is a device that uses compressed air to generate high-pressure hydraulic oil. By driving a hydraulic piston with a pneumatic cylinder, it converts low-pressure air energy into high-pressure hydraulic energy. Through the principle of hydraulic intensification (pressure ratio), it can generate hydraulic pressure many times higher than the input air pressure, without the need for a large hydraulic pump. Typical input air pressure: 5–8 bar; output hydraulic pressure: 50 bar to 350 bar or even higher.
Main Components
1. Pneumatic Drive Module – driven by compressed air.
2. Hydraulic Intensifier Cylinder – converts pneumatic force into hydraulic pressure.
3. Oil Reservoir – stores hydraulic oil.
4. Control Valve Set – includes directional control valve, check valve, and relief valve.
5. Pressure Switch / Sensor (optional) – monitors output hydraulic pressure.
Features
• High Pressure Output: Small pneumatic input produces high hydraulic output.
• Compact and Simple Structure: Eliminates the need for a traditional hydraulic pump and motor.
• Safe Operation: Operates only with compressed air, reducing electrical hazards.
• Easy Maintenance: Modular design of pneumatic and hydraulic components.
• High Energy Efficiency: Consumes air only during operation.
Applications
1. Clamping Fixtures / Jigs: Used with hydraulic cylinders in CNC machining or automated fixtures. Example: workpiece positioning → high-pressure hydraulic clamping.
2. Press-Fitting / Assembly Processes: Provides high pressure for press-fitting, riveting, and assembly operations.
3. Mold Operation: In plastic, die-casting, or stamping molds, drives small hydraulic cylinders for ejection, release, or locking.
4. Testing Equipment: Supplies high-pressure oil for pressure resistance and leakage testing.
5. Handling / Gripper Mechanisms: Provides stable thrust through hydraulic cylinders for automated handling.
Typical Example
In an automated fixture system: The compressed air system provides 6 bar air pressure → supplied to the pneumatic-hydraulic power unit. The unit converts this into 150 bar hydraulic pressure → delivered to the hydraulic cylinder. The hydraulic cylinder then performs clamping, pressing, or ejecting operations.
Advantages Compared
Compared with pure pneumatic systems: Can deliver higher thrust and more stable operation.
Compared with pure hydraulic systems: No motor or large oil tank required → simpler system and lower cost.
Air-Hydraulic Booster Pump
Air-hydraulic booster pumps use compressed air as the driving source to generate high hydraulic pressure by the piston area ratio principle. With 5–8 bar air input, the unit delivers 150–700 bar hydraulic output, eliminating the need for large hydraulic power packs.
Features:
• High pressure output with low air consumption
• Compact design, easy to install
• Energy saving, air-driven with no electric motor
• Low noise, safe and reliable operation
• Easy maintenance
Applications:
• CNC machining fixtures
• Quick Die Change (QDC) systems
• Injection molding / die casting machines
• High pressure hydraulic sources
• Testing & pressure equipment
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.
