Coiling pin is an important tool for coil production process. Coil(i.e. Spring) is formed from wire rod through bending-process by coiling pin installed on coiling machine. The one of important element which is coil production process depends on mainly by coiling pins.
The materials of coiling pin are usually tungsten or high-speed steel, but, to avoid problems caused by high pressure between wire rod and coiling pin, we have succeeded in developing Diamond Coiling Pins, and only SND produce and sell it in the world.
"Our Diamond Coiling pin is suitable for spring manufacturing with non Plating Stainless steel wire, small spring index D/d and high precision very much!!
The materials of coiling pin are usually tungsten or high-speed steel, but, to avoid problems caused by high pressure between wire rod and coiling pin, we have succeeded in developing Diamond Coiling Pins, and only SND produce and sell it in the world.
For the characteristic of diamond, you can get the following benefits from our diamond coiling pin.
1)Pin’s long-life because of diamond’s high durability. 2)Avoid seizure caused by frictional heat, and tool-mark(damage on coil by pin) because diamond’s frictional coefficient is small.
Therefore our diamond coiling pin enable you to produce coil with stable shape and accuracy.
Our diamond coiling pin can be installed on any coiling machines, and we can supply custom-made products based on client’s requirement.
Available range for wire size: φ0.04mm – φ2.00mm (0.0015in – 0.0787in)
Please examine using the our coiling pins in your process.
Many spring manufacturers have begun to use our Diamond Coiling pins.
