Manufacture of springs - Import export

In addition to SPIROL Standard Metric Slotted Spring Pins, SPIROL offers a line of ISO 8752 Slotted Pins to meet market demand for these pins. SPIROL offers Slotted Spring Pins manufactured to the ISO 8752 specification in diameters ranging from 2mm to 12mm in both high carbon steel and austenitic stainless steel in plain finish. ISO 8752 Slotted Pins are not available with supplemental coatings such as zinc plating or passivation due to their propensity to interlock during the finishing process.

SPIROL manufactures Coiled Spring Pins out of 316 stainless steel to meet specific application requirements. Type 316 stainless steel is similar to 302/304 stainless steel with a slightly higher nickel content and the addition of molybdenum. The molybdenum content increases the chemical resistance of this alloy greatly. 316 exhibits superior pitting resistance against sea water, acetic acid vapors, chlorides, sodium and calcium brines, hypochlorite solutions, phosphoric acid, and the sulfite liquors and sulfurous acids used in the paper and pulp industry. This alloy is also austenitic, non-magnetic and non-hardenable using conventional methods. 316 stainless steel has better mechanical properties at elevated temperatures than 302/304 and offers excellent mechanical integrity at subzero temperatures. Typical applications for SPIROL's 316 Stainless Steel Coiled Pins include the following: marine, processing equipment, industrial, oil and gas and medical.

The Series 550 Cosmetic Coiled Pin was designed specifically for cosmetic cases to ensure the perfect balance of strength and flexibility. The 1-1/2 coil construction ensures that the Cosmetic Coiled Pin exerts sufficient radial force to achieve the long-term desired swing torque while protecting the plastic from excessive stresses. The use of SPIROL Series 550 Cosmetic Coiled Pin will simplify your design and manufacturing process. Uniform radial spring force results in controlled hinge movement and a hinge quality that remains consistent over time. Controlled hinge movement is achieved with wider tolerances and lower moulding costs than when a Solid Pin or cut wire is used. Finally, low insertion force and compression of the pin during installation minimises hinge stress and scrap. The net result is the prolonged useful life of the assembly.

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process. SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series, they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling. Visit www.SPIROL.com to learn more!
