What are special springs?
Special springs are non-standard spring types developed for specific applications, complex motion profiles or demanding environments. They often combine multiple functions in a single component or deviate from conventional geometries. Thanks to our in-depth expertise in spring technology, material properties and toolmaking, we supply, among others, the following special springs:
- Conical compression springs: Compress to a compact height, ideal for applications with limited installation space or a progressive spring characteristic.
- Die springs: Robust springs for heavy industrial loads, widely used in dies, stamping tools and mechanical constructions.
- Combined spring assemblies: Combine several spring types in one component, for example a tension spring with an integrated wire form or leaf segment.
- Double torsion springs: Provide torque in two directions or higher torque transmission within a limited space envelope.
- Spring mechanisms with integrated damping: Developed for controlled movement with damping, with or without hydraulic elements; for example in combination with a gas spring.

Applications of special springs
Special springs are developed for advanced technical applications where standard solutions fall short. They are used in sectors where space, loading, precision or durability place specific demands on spring behaviour. Some examples:
- General machinery: Special springs such as conical compression springs and die springs are widely used in grippers, press systems and automated modules. Thanks to their compact design and high force output, they are extremely suitable for dynamic applications with limited installation space. Combined spring assemblies integrate several functions into one component and contribute to a more efficient overall design.
- Offshore & Maritime: In corrosive environments such as offshore platforms and maritime installations, robust, corrosion-resistant springs are crucial. Examples include Inconel spiral springs with constant force in valve systems, and die springs for hydraulic damping in door latching mechanisms. These spring elements withstand seawater, temperature fluctuations and heavy load cycles.
- Medical: In the medical sector, reliability, hygiene and precision are key. Special springs are used in adjustable aids, surgical instruments and dosing systems. Constant force spiral springs provide smooth and predictable movement, while micro springs and combined spring systems enable compactness and control in modular devices.

At De Spiraal, we combine advanced production technology with engineering support to create springs that match your technical specifications exactly. Whether you need a single prototype or a large production run, we think along with you from the design phase onwards. Thanks to our in-house toolmaking and flexible CNC machinery, we produce complex geometries with minimal tolerances. Materials such as stainless steel, phosphor bronze and special alloys are available on request. We deliver quickly, accurately and always tailored to your application.
Benefits of De Spiral special springs
- Unique shaping options: Special springs can be designed in complex shapes, such as tapered conical compression springs, flat-wound spiral springs or springs with multiple segments. This makes them ideal for applications with limited space, varying force profiles or integrated functionality.
- High functional reliability: Through careful material selection, post-treatments (such as hardening, grinding or coating) and tight tolerances, we manufacture springs that continue to operate reliably, even under cyclic loads or in environments with high vibration or temperature demands.
- Space-saving design: Special springs are often selected for their compact installation dimensions combined with high spring performance. Examples include constant force spiral springs in sliding systems or die springs in compact actuators.
- Multifunctional use: Combined spring solutions integrate multiple functions (such as damping and locking) into a single component. This simplifies assembly, reduces the number of parts and increases the level of integration in the final product.
- Consistent quality, even with variation: Thanks to stable production processes, automated quality control and full traceability of material and surface treatment, we guarantee consistent quality, even when designs change or series sizes are smaller.
