Conical compression springs (variable diameter springs)

Conical compression springs, also known as variable diameter springs, are designed to provide high load capacity while optimizing space. Their conical shape allows for more compact compression, as the larger coils can overlap the smaller coils, reducing the spring height when fully compressed. This feature makes them particularly suitable for applications where space is limited but a high force absorption capacity is required.

Conical compression springs can be manufactured with either a constant or variable pitch, similar to cylindrical springs. However, their conical structure allows for more precise control of stiffness and behavior under load. The variability in the coil diameter enables modulation of the spring's elastic response, tailoring it to specific performance requirements.

Technical specifications of conical compression springs produced by Mollificio Romagnoli

Mollificio Romagnoli's variable diameter springs are produced using high-quality materials, including carbon steels, oil-tempered steels, stainless steels, and copper alloys, all conforming to EN standards. The wire sizes for these springs also range from 0.20 mm to 6.00 mm, with the capability to produce small series up to 20 mm in diameter.

Surface treatments offered, similar to cylindrical springs, include epoxy coating, cataphoresis painting, trivalent galvanizing, phosphatizing, and Teflon coating. These treatments ensure long-lasting protection against corrosion and wear.

Versatility of variable diameter springs

Conical compression springs are widely used in sectors such as electronics, automotive, appliances, medical devices, textiles, automation, pneumatics, hydraulics, and electrotechnics. Their ability to provide specific and reliable solutions for complex applications makes them highly versatile.
