Extension springs - Import export

Special eye forms for extension springs: There is an increasing number of potential applications for trumpet-end springs and mounting aids for extension springs – a solution that we have been addressing for many years now. We produce our range of extension springs with German and British standard eyes with wire diameters of 0.25 mm to 4.00 mm. We can also produce special-purpose eyes and other eye forms as needed according to alternative specifications with wire diameters of 0.20 to 4.00 mm.

Bent wire parts represent a separate part of our production range. Bent parts differ from springs such as extension springs, compression springs and wave springs in terms of how they are produced. This type of spring is not only processed with automated machinery, but also involves a considerable amount of special handling, which we perform using our range of state-of-the-art equipment. Precision production with our high-tech machinery: Our range of machinery with an in-house toolmaking workshop enables three-dimensional bent parts to be produced with a wide variety of forms and with specialised finishes applied to the ends. Our range of machining processes includes: Bevelling, embossing, thread cutting, thread rolling, turning and milling. For bent wire parts, both CNC bending and mould-based bending are possible as production solutions.We process wire thicknesses of 0.20 to 8.00mm.Tool-based: 0.50 to 8.00 mm. Coating of part surfaces: Oiling, Vibratory finishing, Galvanisation.

Constant Force Springs are manufactured from flat strip material and spooled to a specific curvature matching the needed pull force. There is practically no limit on extension speed and acceleration. The springs can be fitted in a number of ways and extended partly or completely.

The Murphy Bed mechanism is the most proven of all wallbed designs, having been in use for around 100 years. This design will provide years of trouble-free use and operate for thousands of cycles. Our mechanism is constructed of high-quality steel and is then powder-coated with a scratch proof, black ridge finish. The counter-balance extension springs are made of our special alloy steel. The number of springs needed may be increased or decreased depending on the weight of the mattress and other bedding. We provide a full set of springs to balance all mattresses. A nylon webbing strap holds the mattress in position once upright. The Murphy Bed installation may be attached to the floor; alternatively we have developed a new Wall Mount Bracket to enable the installer to mount directly to the baseboard (skirting board) to avoid cutting into carpet, wood floor, or concrete.

APPLICATION OF HARD DRAWN STEEL WIRE Compression springs, extension springs,and torsion springs for high and dynamic stresses. According to DIN 17223:1964-1

Also for what concerns the extension springs , Mollificio GR is highly specialized for their tailormade production and on specific needs. This type of springs have a wide range of applications, ranging from experimentation to development, and are created to the highest standards of accuracy.

Tension gas spring Tension gas spring also called extension gas spring, traction gas spring or draught gas spring. The outside force on these springs pulls the piston rod inward(operating in the opposite direction of other standard gas springs). Before pulled, the piston rod end is at the shortest position to cylinder, the gas spring is shortest,when we pull gas spring , the pistion rod end become longer and run to the longest position. Traction gas spring is also has the types of freedom & self-locking, and others. Application on doors, lids, hatches and hoods which need keep closed when after out force stop.
