Embodiment Construction

[0014] A circular plate process flow for making reflective moulds, characterized in that the process flow is used for making reflective moulds, and the steps are as follows:

[0015] (1) Original plate treatment: use nickel rods as anodes, select a square metal original plate, use tape for shielding and sealing around the metal original plate, leave a blank space of required size and shape, and then bend it into a cylindrical shape , and set on the circular insulating plate, and connect the two with bolts;

[0016] (2) Cleaning and passivation: carry out lye cleaning and passivation treatment to the blank of metal original plate, described lye cleaning is to rinse the surface of metal original plate with the sodium hydroxide solution of 8wt%~10wt% in order to remove its surface Oil stains and other impurities are then cleaned with clear water; the passivation treatment is to immerse the original metal plate and the insulating plate fixed with it in 0.5wt% to 1wt% potassium dic...

Abstract

The invention discloses a technological process of a circular plate for manufacturing a reflective mould. The technological process is characterized by being used for manufacturing a reflective mouldand comprising the following steps of (1) raw plate processing; (2) wash passivation; and (3) electroforming. According to the technological process, a tetragonal metal raw plate is rolled into a cylindrical metal raw plate for electroforming, and therefore the occupied space can be reduced. When the reflective moulds with the same size are electroformed, the occupied space of the cylindrical metal raw plate is obviously smaller, the land resources are saved, and the production cost is reduced. Moreover, in the raw plate processing, shielding and sealing treatment can reduce the loss of an electroforming bath solution and a nickel rod on the premise of meeting the required size, waste is reduced, cost is saved, and the stripping of the reflective mould is also convenient. The metal raw plate is fixed by an insulating plate, so that the insulating plate can play a role in fixing the metal raw plate, the washing and electroforming of the metal raw plate are convenient, and the process ofelectroforming cannot be affected.

Description

technical field [0001] The invention discloses a process flow for making a circular plate of a reflective mould, which belongs to the field of electroforming technology. Background technique [0002] Reflective film is a basic optical application material with high reflective brightness, which is widely used in traffic safety, outdoor advertising, decoration and other fields. The method for producing the microprism type reflective film is to use a mold having a microprism shape to extrude a 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 mold of the micro-prism reflective film. However, the mold is prone to wear or deformation after long-term use. Therefore, manufacturers of micro-prism type reflective film must have molds capable of continuously producing such micro-prism shapes. Contents of the invention [0003] In view of the deficiencies in the prior a...
