Chain fastening machine is a semi-automatic, simple and inexpensive machine for making chains. It is used to make small-sized cross chains and can produce chains made of metal materials such as gold and silver. It is suitable for jewelry sellers with small shipments. The machine comes with a tungsten needle for welding, and the overall power of the machine is relatively low. One tungsten needle can be used for more than three years, greatly reducing the cost of later use and maintenance.
