Small Cylinder-Type Battery Parts (Existing Size : 18650)

We produce the parts acting as a safety device for cylinder-type small batteries. This product, which is called the CID (Current Interrupt Device) is a part which breaks the current and discharges gas when the internal pressure of battery rises.
The technology of precision mold design and press machining and the technology of ultrasonic welding/laser welding, etc. are applied to ensure that the CID operates normally under a constant internal pressure.
The cylinder-type batteries using this product are mainly supplied to power tools, laptop computers, electric bicycles and segway, etc.
