The advantages and disadvantages of phosphor copper terminals for die

Continuous mode: also known as a 'progressive die', refers to the a trip in the stamping process, phosphorus copper terminals on the mould of different location at the same time to complete two or more than two servings of stamping process the mold. Phosphor copper terminals for the advantages of the die is as follows: (1) in simple die, compound die, continuous productivity is the tallest of three types of mould. (2) because the process is not concentrated in one location, can punch the complex shape of phosphor copper terminals. The strength of the mould and high durability. (3) feeding convenient, reliable, easy to realize single machine automation and mechanization of production. Can use less, no waste, layout. (4) work safety, the operator can not handle knob stretch into the danger zone. (5) phosphor copper terminals and solid wastes are leaking, can use high speed press production. Phosphor copper terminals continuous die shortcomings are as follows: (1) parts precision is generally lower than the compound die. The poor surface quality. (2) due to the need of the mould structure, parts on value is bigger, material utilization ratio is lower than compound die. (3) the stainless steel terminal of complex shape, die structure is complex, difficult to manufacture.
