Problems solved by technology

[0006] Assuming that a sufficiently thick electroformed metal sheet is formed by the traditional electroforming method, if 3mm (3000 microns) is taken as an example, if the deposition growth rate is 0.4 microns per minute, since it is unidirectional deposition, it theoretically requires 7500 microns. Minutes, which is 125 hours after conversion, which is equivalent to 5.2 days, which is very time-consuming, and after electroforming is completed, internal stress is accumulated on the thick layer of material, which is prone to deformation

Abstract

A process for preparing the electroforming metal mould includes preparing metal material, preparing electroforming metal sheet, plastic mould corn and electroforming substrate, preparing powder supply, electroforming to generate deposit layer, and demoulding. Its advantages are short time, and high binding force.

Description

technical field [0001] The invention relates to a method for manufacturing an electroformed metal mold, in particular to a method for manufacturing a composite electroformed metal mold, which has the advantages and effects of firm joint interface, fast processing, and not easily deformed under high temperature. Background technique [0002] In view of the combination of electroformed metal sheets and mold steel mold cores formed by electroforming on the market, each has its own shortcomings. [0003] Although the required electroformed sheet thickness can be quickly achieved by vacuum adsorption, the mold production needs to be quite precise, and vacuum equipment needs to be added, making mold maintenance difficult. [0004] The electroformed metal sheet will be deformed and the surface profile of the electroformed metal sheet will be destroyed if the flame melt-blown joint or the laser welding method is used. [0005] Or, using mechanical fitting or screw locking, the elec...
