As we know, connector, as a port to transmit signals, has been widely used in various industries such as mobile phones, computers, program-controlled exchanges, household appliances and other fields. At present, foreign manufacturers occupy the high-end connector market, domestic manufacturers are mainly low-end, which is partly affected by the level of connector mold industry. The quality of a mold determines whether the connector is good enough, so because of this, good connector mold is harder to make.
Why is the connector mold difficult to make?
Because connector molds involve injection molding, terminal stamping, electroplating, etc., Guosheng mainly produces terminal stamping molds, including terminal molds for SIM card of mobile phone, STOCK terminal molds for CPU slot of computer, electrical terminal molds, etc. Further, the connector has high requirements for the mold manufacturing industry, which need to have the following three requirements:
1, need to have a high level of mold design, because of different shapes of terminals, connectors have different structures, how to carry out a reasonable design is very important, if the structure is ignored lead to unqualified products.
2, high precision equipment, connector terminals require high precision processing equipment, foreign equipment accuracy can reach ± 0.002mm, and the general domestic equipment can only reach ±0.01mm.
3, good processing basic technology. A good connector mold needs a perfect combination of design, equipment and process.
At the same time, this equipment matching requirements are higher, technical barriers are relatively high, the use of advanced CNC plane grinding, automatic optical curve grinding, slow wire cutting, machining center and other equipment combination, production. In the future, the requirement of connector terminal mold is higher and higher, which is caused by the trend of connector interface miniaturization and high data transmission rate. Therefore, this has higher requirements for mold equipment, materials, quality and so on. The punching speed of the mold has reached 500 RPM -3000 RPM, which also puts forward higher requirements for mold enterprises.
