Raw material selection

The manufacture of fuses requires the use of materials with good electrical conductivity and flame retardant properties, such as copper, silver, aluminum, tungsten and other metal materials, as well as ceramics, glass fiber and other non-metallic materials. When choosing these materials, it is necessary to select them according to the characteristics and requirements of the actual circuit to ensure that they can meet the rated current and breaking capacity of the fuse.

Manufacturing Components

The constituent parts of fuses mainly include fuse elements, contacts, housings, fuse holders and other parts. These parts need to go through the processes of mold manufacturing, injection molding, cooling and demolding to ensure the accuracy of their appearance and dimensions. Among them, fuse manufacturing usually adopts stamping, molding, punching and other processes to prepare the fuse element, which requires precise control of its material viscosity, diameter and length and other parameters to ensure the rated current and breaking capacity of the fuse.

Assembly

Assembly is a very important part of the production of fuses, the need for various components in accordance with the design requirements for assembly, and to ensure the normal operation of the components. The assembly process also requires quality inspection, the parameters must meet the quality requirements before proceeding to the next step.

Test

It is a very critical part of the fuse manufacturing process, mainly including electrical performance test and mechanical performance test. In the electrical performance test, it is necessary to detect whether the rated current and breaking capacity of the fuse and other parameters are in line with the standard, and whether there is any leakage and other problems. In the mechanical performance test, it is necessary to detect whether the mechanical strength of the fuse meets the use requirements.

Packaging and transportation

Finally, after the fuse is made, it needs to be packed and transported to ensure its safety during transportation and use. Special care should be taken not to use rough materials that may damage the fuse.
