Secondly, the instability of the connection is one of the main problems. Metal key covers basically have right angles. If the manufacturer does not handle the mold properly, it is easy to have problems such as loose packaging and easy to fall. Therefore, the right angle of any product needs to be specially designed during mold processing. In addition to structural problems, the hardness of the product is too high, and the overall product is too brittle, which leads to instability of the connection during long-term stretching.
Scratches appear on the surface, which shouldn’t happen to metal products. If they occur, most of them are caused by manufacturers. Generally speaking, protective sleeves made of metal will not wear out quickly under normal conditions, unless The product hardness is too low and the processing time is too short. In order to improve the product efficiency and reduce the processing time during the production and processing process, the hardness of the metal product is not enough to be ejected in advance.
In addition to the above reasons, there are also other rare problems, such as breakage when ejecting the mold. This phenomenon is mainly caused by the material hardness is too high, the mold and the rubber material are stuck, the raw material storage time is too long, the vulcanization is not ripe, and the curing agent fails. , The parting line of the product is too thick, causing the parting line of the product to break, etc. These are common problems of unqualified products
