ELECTRO-FORMING

As a method of manufacturing products using electroplating, it attaches (plates) metal on the pattern by electrolysis till gaining thickness on the surface of master, separates it from master, and manufactures products having the opposite shapes from master.

Electroforming & Plating

Division ELECTRO-FORMING ELECTRO-PLATING
Deposit Thickness several ㎛~several tens ㎜(Foil~Bulk)
0.1~0.3㎜(SRI-Tech Product)
0.1~30㎛
(Coating)
Substrate Adhesion To make easy exfoliation(separation )
is important
To make no exfoliation with high
Substrate Adhesion is important

FORMING

The products manufactured using electroforming are used in the various industrial fields owing to the characteristics to be manufactured using transfer method. In addition, there’s superiority in using forexterior/interior, decorations & logo badge of cell phone, home electronic appliances & motors.

Components of Electroforming

Basic manufacturing constitution of Electroforming

In case of putting electrodes in the solution containing an ion of metal and turning on the electricity, plating metal(Ni) ion in the solution generates the thin film on the surface of master (PATTERN) of the negative pole. The thin film (Metalic materials) attached byelectrolysis (Electrolytic deposmon) is separated in master and manufactured as end products through the second processing.

Basic manufacturing constitution of Non-Allergy Electroforming

In case of putting electrodes in the solution containing an ion of metal and turning on the electricity, plating metal(Ni) ion in the solution generates the thin film on the surface of master(PATTERN) of the negative pole. The thin film (Metalic materials) attached by electrolysis(Electrolytic deposmon) is separated in master and manufactured as end products through the second processing

Characteristic of Ternary alloy

Aim

  • -

    Cost reduction [Ensure cheap plating having the similar property of matter because of high price of Pd plating]

  • -

    Ensure reliability [Replace to plating cheaper than Pd with more reliability]

Characteristics

  • -

    Replace Pd plating to silver-white plating color

  • -

    Non allergy reaction

  • -

    Superior throwing power & corrosion resistance
    : Like the general alloy plating, it has beautiful color and superior corrosion resistance because of uniform particles with almost no pores

  • -

    Free to ROHS without containing of Pb brightener unlike the existing ternary alloy solution

  • -

    Require AAS or CIP instruments for controlling solution

  • -

    Have difficulty in controlling than single plating solution because solution changes color according to component content, current density & temperature

  • -

    Have composition of Cupper (70%)+Tin (20%)+Zinc(10%)

Electroforming TANK

  • Nickel electroforming tank

  • Copper electroforming tank
