Firstly, the purchased round steel wire is cold-drawn and punched into a blank with a heading machine-threading with a rolling machine-carburizing, quenching and tempering in a heat treatment line-phosphating or blackening in a line.

The upsetting machine is a horizontal punch, the thread rolling machine uses two thread rolling plates for thread processing, the heat treatment equipment is a steel soft mesh assembly line, the quenching furnace uses acetone as fuel, and the equipment is installed in the pit.

If all the equipment is self-provided, the cost is quite large. However, you can buy a hoist and a wire rolling machine first. It costs about 60,000 to 80,000 yuan.
