Title:
ELECTRONIC CIGARETTE ATOMIZATION ASSEMBLY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/163922
Kind Code:
A1
Abstract:
An electronic cigarette atomization assembly and a manufacturing method therefor. The manufacturing method for the electronic cigarette atomization assembly comprises the following steps: S1, mixing metal powder with an organic mixture by means of ball-milling to prepare a metal mixture; S2, putting a matrix in an MIM mold; S3, performing injection molding on the metal mixture into the MIM mold and on the matrix by an injection molding machine according to a heating body pattern in the atomization assembly to form an atomization assembly blank; S4, dewaxing the atomization assembly blank to remove the organic mixture; and S5, performing sintering in a vacuum or inert atmosphere, melting the metal powder, cooling same to form a heating body tightly attached to the matrix, and forming the atomization assembly by the heating body and the matrix. The manufacturing method for the electronic cigarette atomization assembly is simple in process, favorable for batched production and high in production efficiency.
