Advantages of traditional crank press technology include low production cost and high speed production rate (30~1200 pieces per minute). Requirements of complicated die and limited product forming are the shortcomings. Additionally, the advantages of traditional hydro-forming technology are good product quality, complicated geometric shape and easy-made die. However the disadvantages are expensive cost of equipment, low production speed (less than 5 pieces per minute), and is not applicable to multi-station progressive process and high pressure working environment that has the concern of industrial safety.

传统曲轴冲压技术之优点是生产成本低廉及生产速度快(每分钟30~1200件)，缺点是模具复杂及成品形状成形性受限制；传统液压成形技术之优点是成品品质佳、几何形状容许大变形及模具简易，缺点是设备成本高、生产速度很慢(每分钟5件以下)、不适合多工程连续加工且具有高压之工安问题。
