Mould plates (top clamp plate, stripper plate, support plate, ejector plate and ejector retainer plate) have many cutting operations in their manufacturing technologies, milling, drilling, that are usually made on CNC machine tools. These operations require a lot of time in manufacturing, many tools (for example for different types of diameters of the holes) that increase the time for manufacturing. After these operations are completed, other grinding operations are necessary, which increase even more the manufacturing time and the overall price for that product. The time for manufacturing and the cost for those plates can be reduced by using water jet cutting.
