The power plug can be roughly classified into a conversion power plug, an injection molding power plug and an assembly power plug.

And (3) converting a power plug: the standard of the power plug of each country is different, for example, the power plug of China is not used in the United states, and a conversion plug is required to complete conversion. Thus requiring a changeover power plug. The conversion power plug is to convert the plug of one national standard into the plug of another national standard.

Injection molding of a power plug: the injection molding plug is characterized in that the plug and the wire are pressed together through high temperature and high pressure, and once formed, the plug cannot be assembled and disassembled, so that the power plug has obvious characteristics, and is stable and safe. More than 80% of the power plugs generally distributed on the market are the power plugs.

Assembling a power plug: the assembling plug is that the power line and the plug are fixed together through screws and the like, but can be assembled and disassembled in the using process, so that the flexibility of the power plug is ensured. For example, there is a large percentage of the uk market that uses such fitted power plugs.

Wherein, power plug moulds plastics includes little english standard plug, and current little english standard plug inner tower does not have the pressure lid, production little english standard plug need little english standard plug inner tower and wire rod hot pressing under high temperature, highly compressed condition combine, carry out secondary operation after that, add the pressure lid, just can form the finished product, manufacturing cost is high, and production efficiency is low.
