Square plate process flow for manufacturing reflective mould

Abstract

The invention discloses a square plate process flow for manufacturing a reflective mold. The square plate process flow is characterized in that the process flow is used for manufacturing the reflective mold and comprises the following steps of (1) original plate processing; (2) cleaning and passivation; and (3) electroforming. According to the square plate process flow, a square metal original plate is adopted, so that the structure is simple, the design is reasonable, and fixing, cleaning and use are more convenient; moreover, the shielding and sealing treatment in the original plate treatment can reduce the loss of electroforming bath liquid and nickel rods on the premise of meeting the required size, waste is reduced, the cost is saved, and stripping of the reflective mold is facilitated; and the metal original plate is fixed by an insulating plate, so that the role of fixing the metal original plate can be played, cleaning and electroforming of the metal original plate are convenient, and the electroforming process are not affected; and carbonate is added into the electroforming bath liquid, the number of ions in the bath can be increased, and the electroforming rate is increased.

Description

Technical field [0001] The invention discloses a process flow of a square plate for making a reflective mold, which belongs to the field of electroforming process. Background technique [0002] Reflective film is a basic optical application material with high reflective brightness, which is widely used in traffic safety, outdoor advertising and decorative decoration. The method of producing the microprism reflective film is to use a mold with a microprism shape to extrude the heated resin film, so that the resin film forms a microprism reflective layer. The key factor that determines the quality of the micro prism reflective film is the micro prism reflective film mold. However, the mold is prone to wear or deformation after long-term use. Therefore, manufacturers of micro-prism-type reflective films must have molds capable of continuously producing such micro-prism shapes. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present...
