Method for local electroplating sheltering and hanging aluminium alloy cavity of communication filter

Abstract

The invention discloses a method for local electroplating sheltering and hanging an aluminium alloy cavity of a communication filter. The method is characterized in that the method comprises the following steps: 1) facilitating a silicone waterproof jacket which is matched with the aluminium alloy cavity to be electroplated, sleeving the silicone waterproof jacket on the surface of the aluminium alloy cavity; 2) fixing the aluminium alloy cavity with the silicone waterproof jacket on a rotatable square fixed frame; and 3) hanging the square rotary fixed frame and the aluminium alloy cavity in an electroplating bath for rotary electroplating. The method adopts the silicone waterproof jacket to be matched with the square rotary fixed frame for use, the part of the shape which does not need to be electroplated uses the silicone waterproof jacket for sheltering, thereby exposing the part which needs to be electroplated; then the cavity with well arranged silicone waterproof jacket adopts a rapid press board and a stainless steel clamp to be fixed on the square rotary frame, thereby leading the cavity to carry out the adjustable-speed rotary electroplating in the electroplating bath, achieving the purposes of evenly electroplating the exposed part of the cavity and keeping the original color of the shape, further improving production efficiency, reducing production cost and improving product quality.

Description

technical field [0001] The invention relates to an electroplating method for an aluminum alloy cavity of a communication filter, in particular to a partial electroplating shielding and mounting method for the aluminum alloy cavity of a communication filter. Background technique [0002] Electroplating is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts. It can prevent corrosion, improve wear resistance, conductivity, light reflection and enhance the appearance. [0003] A technology that uses electrolysis to deposit a metal coating with good adhesion but different properties from the base material on mechanical products. The electroplating layer is uniform than the hot-dip layer, and is generally thinner, ranging from a few microns to tens of microns. Through electroplating, decorative protection and various functional surface layers can be obtained on mechanical products, and workpieces that are worn and proc...

Problems solved by technology

High-temperature tape can only be used for plane sealing, and the edge boundary is poor. If there is grease and dirt on the surface of the part, the viscosity of the high-temperature tape will decrease, so that the electroplating solution will penetrate into the sealing surface during electroplating and cause defects. ; However, the cost of using resist-plating paint is high, the process is long, and the right-angled part of the part is leaking due to the fluidity of the resist-plating paint. It is difficult to remove the resist-plating paint after the blind hole is sealed, which affects the electroplating effect
