Custom Pneumatic Fixtures
Engineered for Various Industrial Applications
Pneumatic Fixture
A pneumatic fixture is a specialized workholding device that uses compressed air to generate clamping force for securing workpieces during manufacturing operations. These fixtures transform air pressure into mechanical force through precision-engineered cylinders and clamping mechanisms.
Unlike manual fixtures, pneumatic fixturing systems provide consistent, repeatable clamping pressure across multiple points simultaneously. This automation capability makes them ideal for high-volume production environments where efficiency and consistency are paramount.
Core Components
- Pneumatic cylinders that convert air pressure to linear force
- Clamping mechanisms (swing clamps, work supports, or linear clamps)
- Control valves for operation sequencing
- Base plate or structure for mounting components
- Air supply connections and distribution manifolds
Pneumatic Fixture Manufacturing Services
Fecision manufactures a comprehensive range of clamping fixtures to address diverse workholding requirements.
Each type offers specific advantages for different machining scenarios and workpiece geometries.
Precision Engineering
Our pneumatic fixtures are manufactured to exacting tolerances using high-grade materials. Each component is precision-machined to ensure perfect alignment and consistent performance over thousands of cycles.
Modular Adaptability
Fecision fixtures feature modular designs that adapt to various workpiece geometries. Our quick-change components allow rapid reconfiguration for different production runs, minimizing downtime.
Advanced Automation
Our pneumatic fixtures integrate seamlessly with production automation systems. Optional digital pressure monitoring and position sensing provide real-time feedback for process control.
Pneumatic Fixtures for Superior Production
-Enhanced Operational Efficiency
Pneumatic fixtures dramatically reduce workpiece setup time compared to manual clamping methods. With the push of a button, operators can simultaneously engage multiple clamps, reducing cycle times by up to 70% and increasing throughput.
The consistent clamping force provided by pneumatic mechanisms also eliminates variations in operator technique, ensuring uniform quality across production runs regardless of who operates the equipment.
-Improved Quality and Consistency
Our pneumatic fixtures deliver precise, repeatable positioning for every workpiece. This consistency translates directly to improved part quality, reduced scrap rates, and fewer quality control issues in your production process.
The controlled application of clamping force prevents workpiece distortion while ensuring secure holding during machining operations. This balance is particularly valuable when working with thin-walled or delicate components.

Applications of Pneumatic Fixtures
Welding Applications
Our pneumatic welding fixtures provide precise component alignment and secure holding during both manual and robotic welding processes. The fixtures maintain consistent positioning despite heat-induced expansion, ensuring weld quality.
Common applications include automotive frame assembly, structural steel fabrication, and precision sheet metal welding where dimensional accuracy is critical.
Machining Operations
Pneumatic fixtures excel in CNC machining environments where consistent workholding is essential for dimensional accuracy. Our fixtures provide rigid support that minimizes vibration while allowing full tool access.
Ideal for milling, drilling, and turning operations on components ranging from small precision parts to large structural elements requiring multi-point clamping.
Assembly Processes
In assembly operations, our pneumatic fixtures ensure components are precisely positioned for joining processes. The fixtures integrate seamlessly with automated assembly systems for high-volume production.
Applications include electronics assembly, mechanical component assembly, and product testing where consistent positioning and gentle but secure holding are required.
