Compression Springs is the most common type of springs. The majority of compression springs are cylindrical and linear, but to this group belongs also conical, barrel shaped, tapered out ends and more. The design can be adjusted to fulfil a wide range of requirements concerning spring characteristic.
We provide both stock springs and bespoke springs. Material grades covers the whole range from normal spring steel to nickel alloys, titanium alloys and copper alloys. We cold coil springs up to wire diameter around 18 mm and hot coil for larger springs.
Our maximum bar diameter for hot coiling is 65 mm. The conditioning processes – heat treatment, shot peening and presetting – are adapted according to the requirements. We offer different surface treatments for corrosion resistance or desired visual appearance.
