As we mentioned ,to check quality of die casting parts,there will always be limit samples which are also called boundary samples. For example,we make a limit sample board for our die casting aluminum frame as below photo,we will select which sizes scrope products are accepted,they are classified to upper level,middle level,and floor level,products which are beyond floor level can't be accepted as to customer confirmed.
Our quality team will always have serious attitude to make sure each product good quality when they reach our customers.
