Background
The SIM card is an abbreviation of Subscriber Identity Module (SIM), also called Subscriber identity card (SIM), smart card, and GSM digital mobile phone must be installed to be used.
There are four common SIM card types, which are: standard SIM card, Mini SIM card, Micro SIM card, Nano SIM card.
In order to facilitate the use of users, a sleeve cutting card production process is adopted in the card production process, and various types of cards are integrated on one card. The cards currently available on the market are divided into a large card in which four kinds of cards are collectively cut into one card body and a small three-cut card in which the latter three kinds are cut into one card body. The three-cut small card is convenient to use due to small card body area, and is widely popularized and used in China Mobile companies. The small cards are easy to deform and bend in the production process of the three-cut small cards, so that the production difficulty is high. The existing punching mode easily causes the deformation of a small card and can not meet the requirement of card flatness.
