Kind Code:
A1
Abstract:
A stainless steel and plastic combined piece and a processing method therefor. The combined piece comprises a stainless substrate (1). When etched by an etchant, the surface of the stainless steel substrate (1) is provided with several recessed structures (11). The average depth of the recessed structures (11) is 0.1-30 micrometers and the average width is 0.2-15 micrometers. A plastic (2) is injection molded on the stainless steel substrate (1). Parts of the structure of the plastic (2) are embedded in the recessed structures (11). The recessed structures (11) formed when the stainless steel substrate (1) is etched by the etchant are of the micrometer level, the combined piece is provided with improved stability and increased airtightness when the plastic (2) is injection molded, thus reducing process steps, reducing production costs, being applicable in large-scale production, placing no special material requirement with respect to the injection molded plastic (2), and having a widened range of applications.
