Torsion springs

Torsion springs are mechanical components designed to store and release rotational energy. They resist twisting or rotational forces by exerting torque, making them essential in applications requiring controlled rotational movement.

Design Variations:
Baumann Group offers several configurations of torsion springs to meet diverse application needs:

• Single Torsion Springs: Feature a single coil and are typically used where space constraints are a concern.

• Double Torsion Springs: Consist of two coils wound in opposite directions, providing balanced torque and reducing stress on the spring.

• Inner/Outer Legs: Designed with legs that extend inward or outward, suitable for specific mounting requirements.

• Bent Legs: Legs are bent at various angles to facilitate installation in complex assemblies.

Materials:
Torsion springs are manufactured from various materials to suit different operational environments:

• Spring Wire: Standard wire used for general applications.

• Oil-Tempered Wire: Offers enhanced fatigue resistance, ideal for high-stress applications.

• Stainless Steel Wire: Provides excellent corrosion resistance, suitable for medical and food-grade environments.

 Surface Treatments:

To enhance durability and performance, Baumann Group applies various surface treatments:

• Blank: Untreated surface, suitable for non-corrosive environments.

• Pre-coated (Zi/Al): Zinc-Aluminum coating for improved corrosion resistance.

• Zinc-Lamella/Top Coat: Advanced coating techniques offering superior protection against environmental factors.

Manufacturing Specifications:

• Wire Diameters: Ranges from 0.5 mm to 6 mm, accommodating a wide range of applications.

• Spring Ends: Custom-designed ends to fit specific installation requirements.

• Cleaning: Ultrasonic cleaning processes using water, alcohol, hydrocarbon, or perfluorinated solvents to ensure cleanliness and precision.

• Cold-Set: Cold-setting processes to maintain dimensional accuracy and spring characteristics.

Typical Applications:
Baumann Group's torsion springs are utilized in various industries, including:

• Automotive: Ignition systems, seating mechanisms, and power transmission components.

• Medical Devices: Pens, autoinjectors, metering systems, safety syringes, and lancets.

• Industrial Equipment: Braking systems, combustion engines, and other mechanical assemblies.
