Precise Manufacturing Process Ensures 48V DC Mcb Quality and Product Safety
There are five processes in the production of 48v dc mcb. The first is assembly, assembling all the parts into the plastic shell, and fixing the parts with welding technology or screws to prevent the parts from shifting during use and affecting the use.
Then there is the verification, the first verification after the parts are assembled, to debug the instantaneous and delayed action characteristics of the product, and to check whether the fixed position of the parts is reasonable and whether they can operate normally.
The 48v dc mcb shell is composed of two plastic plates. Riveting is to fix the two plastic plates after the parts are fixed and debugged, so as to prevent the displacement of the parts and the plastic plates and protect the parts from being damaged. Then check again to ensure that the plastic shell is riveted correctly and there is no displacement, to ensure that the internal parts of the product can operate correctly.
The last is packaging. The completed product is printed with brand labels, specification information, etc., and then lasered. Sometimes this step is done before assembly, and then the product you receive is packaged and labeled.
