Custom Compression Springs Manufacturer
Custom-made compression springs tailored to your specific specifications. Discover Filame's deep expertise, production capabilities, sector expertise, materials and finishings.
Compression springs operate generally via pushing motion. Compression spring bodies are generally cylindrical, conical or bi-conical in shape.
Available in all sizes and grades of 0.1 to 8 mm wire thickness, Filame manufactures according to your needs from the single piece ( prototype) but also in small, medium and large series. Compression springs are available only up to 20 mm in small and medium series.
