Return Tension Springs for Packaging Lines
Extension springs ensure the dependable operation of reset mechanisms, tensioning units, and backlash compensation assemblies. They find heavy application in blister packaging units, cartoners, dosing systems, and conveyor lines. High-precision coiling paired with consistent elasticity delivers smooth mechanical motion while preventing cycle disruptions.
DATAPHARM designs and manufactures custom tension springs in diverse configurations. Automated CNC coiling combined with controlled heat treatment yields high fatigue strength and resistance to mechanical wear.
📌 Primary Applications
- Returning levers, cams, and shutters in automated filling machinery.
- Maintaining continuous tension on drive belts, chains, and flexible packaging films.
- Compensating for mechanical play and damping vibrations in blister machine nodes.
- Providing active clamping force in marking and capping stations.
✅ Key Advantages
- Tailored production according to engineering drawings, specs, or reference samples.
- Exceptional resistance to cyclic fatigue and stress deformation.
- Precision heat treatment (quenching and tempering) for maximum operational life.
- Versatile hook designs (English, German, extended loops).
- Corrosion-resistant finishes suitable for high-humidity environments.
