Our machined reversing solutions are characterized by maximum customizability and maximum precision. They are used in areas such as valve technology, medicine, aviation and mechanical engineering. Our products meet the highest international standards in terms of design, materials and production technology and offer the following advantages:
Precision
Maximum individualization
Improved dynamics
Function integration
Increased service life
Precision
Precision and minimal force tolerances through machining production
- The spring rate of a coiled spring lies within a tolerance range of +/-10%, while machine-produced springs lie in the range of +/- 5%. We can also manufacture precision springs with a tolerance of +/-1% on a customer-specific basis.
- Machining processes do not generate any internal stresses that have to be overcome in order to apply force.
Maximum individualization
Maximum customization thanks to free choice of materials and CNC technology
- CNC production enables maximum customization in terms of dimensions, spring rate and geometry.
- Since all machinable materials can be used, a wide selection of materials is available. In addition to conventional materials, lightweight aluminum springs, electrically insulating springs made of plastic or even high-strength titanium springs can also be produced.
Improved dynamics
Improved dynamics, for example through multi-start helix
- A multi-start spring can be used to manufacture components that can absorb compressive, tensile and torsional forces at the same time.
- With multi-start springs, the compression or tension is distributed over several points, resulting in an even, parallel distribution of force. As this prevents undesirable lateral buckling of the spring, there is no need for additional spring guidance.
Function integration
Reduced assembly effort thanks to Function integration in the component
- The integration of additional functions (e.g. bore, thread, flange or grooves) optimizes the installation space and greatly simplifies assemblies.
- Integrated connections (e.g. flange ends, grooves, threaded holes/spigots, etc.) increase the stability of the spring.
Increased service life
Increased service life through optimization of the helix geometry at the start and end area
- The strength of the spring in the critical area can be increased by “thickening” the spiral outlet.
- By using the finite element method (FEM), precise statements can be made about strength and service life.
