How to manufacture spring washers

Many people will be curious about how the spring washer is produced, so we will talk about the main production process, the wire with the spring coiling machine into a spring coil, and then cut into a spring pad with a cutting machine; you put a handful of the same spring pad before and after the stack, it is clear.
