Steel Draw Plates:- The best draw plates were made by “JOUBERT” &
“PELLERIN” in FRANCE. These were expensive and the ITALIANS put them
out of business. The Italian draw Plate was never as good. Then
there are steel draw plates Made in INDIA (no good at all).
Tungsten Drawplates these are far better than the Steel draw plates.
These can be highly polished (mirror finish). Due to intensive labor
the better ones came from TAIWAN. The three most popular sizes were
SRM-10, SRM-20 and SRM-30.
SRM-10 24 hole wire sizes, SRM-30 36 hole wire sizes & SRM-30 24
hole for Tubes.
Recently they have been copied by China and they put out a 39 hole
Draw Plate for wire. This may be Tungsten Carbide but does not have
the high polish and is not as good.
The inner surface of the hole in the draw plate determines the
finish on the wire that you draw. Tungsten is cast and some of these
Chinese drawplates have porosity holes which translate into
scratches. The Tungsten Insert is rather small compared to the
TAIWAN drawplates. The Chinese do not know or cannot afford the
Look for the SRM #'s & ask the vendor if the product is from China.
Always take a 10x magnifier and inspect the holes. If the price is
cheap then it cannot be the real thing.
We have been selling the KARAT Draw Plates for the past 20 years &
never had a complain except when customers go for price.
