In making spring process, spring shape shall be made by pushing wire rod to coiling pin. And performance of coiling is determined mainly by coiling pins.Material of pins in coiling machines is usually carbide or super-hard metal. We have succeeded in developing diamond coiling pins.

Carbide or super hard-metal dies are typically used for coiling pins. Our coiling pins utilize PCD (poly-crystal diamond) characteristics to a maximum extent.These pins have some additional features besides long lifetime. One additional feature is generation free of the tool-mark (seam in the form of a line), so you can attain high accuracy in spring manufacturing process. The other additional feature is to obtain long spring form, so spring production line can be stable and highly reliable. Furthermore, in the stainless steel coiling process by conventional pins, you need to supply lubricating liquid, so the variation of its concentration and poultice level can occur coiling performance problems. Our diamond coiling pins do not occur this kind of trouble. Please examine our coiling pins in your process. Many coiling manufacturers have begun to use our coiling pins.

For example, the process using carbide or super-hard metal coiling pins of the 10,000 coil durability can be improve to the level of 10,000,000 coil durability by our coiling pins.You can apply our pins to small D/d number coiling. These are also applied to processing the internal spring of the catheter in medical application.

More than 20 worldwide coil manufactures introduce our diamond coiling pins
