Abstract

The invention relates to a manufacturing method for an AgMeO electrical contact and an integrated component thereof. Firstly coated silver-oxide composite powder is prepared and put into the powder cylinder of a 3D printer; and then a three-dimensional model of the AgMeO electrical contact and the integrated component thereof is established via a computer so that 3D printing formation of the AgMeO electrical contact and the integrated component thereof is completed. Direct and rapid formation of the AgMeO electrical contact and the integrated component thereof from raw material to the finished product is realized by 3D printing so that the raw material and production cost can be saved, zero inventory and zero time delivery can be realized, and thus the manufacturing method is a new method for preparing the AgMeO electrical contact and the integrated component thereof.

Description
