NEED STATEMENT

Wires are used for electrical connections in a wide variety of electronics products, industrial machines, switchboards etc. Many of the products and machines require wires of specific sizes for production purposes. So here we design an automatic wire cutting and stripping machine for instant wire cutting and stripping.
