Efficient assembly and packaging of pneumatic components
Flow control valves are often used as either supply or exhaust air throttles to ensure the reliable operation of pneumatic systems in a wide range of applications. These valves play a crucial role in the control and regulation of air flows in various applications.
Flow control valves are assembled in a cycle time of 30 parts per minute on the ultra-modern PIA assembly system consisting of three assembly cells. The valves are packaged in a tubular bag packaging system and made available to the end customer.
The system enables the production of 18 different type of variants using our patented clictec system. The units are laser-marked with the necessary information before packaging. This ensures complete traceability and a high level of quality assurance.
Most interesting process steps are:
- Laser welding: Two plastic parts are laser-welded in an axial direction, and in one size also in a radial direction, using gold-plated ring mirrors. This process ensures a stable and permanent connection between the components.
- Automatic check: The tightness and flow direction of each valve are checked fully automatically. This ensures each valve meets the required quality standards and functions reliably.
The advanced manufacturing processes and strict quality control guarantee that the flow control valves manufactured on the assembly line meet the requirements and work reliably in their applications.
