adv.   nicoform

nickel book
The Sulphamate Nickel How-To Guide

by David Crotty, PhD & Robert Probert

on

Q. Hi.
We have just started manufacturing nickel screens for textile. I am having problems regarding :
a. brightness and
b. consistency in product parameters - like diameter and open area of holes in screens

Q. We are a leading manufacturer of nickel rotary screens for textile Printing. We manufacture screens of nickel metal only. Now We want to go for Nickel-Iron Plating, so guide us for following:

1. First we make 35 micron screen sleeve from mother roll in pure nickel bath (anode-Nickel).

2. Then that sleeve goes for 65 microns Plating for Nickel-Iron Plating (anode-Nickel). (Advise us for Proper Anode with %)

3. So guide us For proper Nickel-Iron Plating to produce proper Nickel perorated Rotary Screen for below Queries

Queries:-

(a)Salt: What type of Salt of Iron we should use for Nickel-Iron Plating? (with measurement)

(b)Corrosion-Additive: During Nickel-Iron Plating Process Fe++ makes Fe+++ (ferric), so Corrosion Develops. So What type of Additive we should use to stop Corrosion and for better Shining? (with measurement)

(c)Brittleness: During the Nickel-Iron Plating our Nickel Screen gets brittle.

So What type of Additive we should use to avoid brittleness? (With Measurement) So guide us for above queries. Waiting for your Reply. Thanking you.

A. Hi Yasin. I am not aware of anyone who is successfully using nickel-iron for precision electroforming, and afraid that, even if I did, the broad unidirectional technology transfer you seem to be requesting sounds highly unlikely.

Some alloys like nickel cobalt can probably improve the mechanical properties over plain nickel screens, but I doubt that is the case with nickel-iron screens, so what is the benefit you are looking for -- lower cost? Thanks!

Luck & Regards,

How to make nickel perforated textile screens

Q. Regarding the nickel perforated screen for textile printing.

Which method or chemical composition will be better to get the high open area in finer mesh for textile rotary screen manufacturing?

A. Hi Ajay. Nickel electroforming, probably from a nickel sulphamate plating bath, is the way forward.

Picture this, which is how vinyl records and CDs are made: start with one perforated screen made of whatever material you wish, perforated by whatever technology you wish. Passivate it so plating won't stick too well to it, then do a heavy plating of sulphamate nickel on one side only. Separate the plating from the original screen and use the electroform you just made as the mold for electroforming another screen; remove the screen and electroform another; do it again and again.

Luck and Regards,
