Extension springs, or coil extension springs, are used wherever a tensile force must be applied. They are commonly employed as return springs in vehicle construction, as well as in garage doors, locks, bed bases, and relays in plant and equipment engineering. Various types of eyelets allow for connection to adjacent components. The selection depends on the load and application.<\/p>\n\n\n\n

For the production of extension springs, we offer the optimal manufacturing process for all requirements. We produce individual units in our factory. For small series, we use semi-automatic production, combining the advantages of manual and large-scale manufacturing. For large series, we generally rely on fully automated production.<\/p>\n\n\n\n

Our machinery includes a wide range of automatic spring coilers for pre-assembled extension springs with standard eyelets, as well as CNC-controlled production centers with up to 28 individually programmable axes for producing special eyelets and complex geometries.<\/p>\n\n\n\n

Our greatest strength lies in the wire thickness range from 0.20 mm to 5.00 mm. Depending on the geometry, design, and quantity, we can manufacture springs with a maximum wire thickness of up to 16.00 mm.<\/p>\n<\/div>\n<\/div>\n\n\n\n
