Spectrometer Copper Die for sample preparation
Spectrometer Copper Die as per Indian Standard ISO 14284:1996 for coin sample preparation for spectrometer analysis for cast iron and ductile iron samples only.
Mould form from steel, casting on copper block ensures unidirectional chill solidification on the analytical side of the sample only.
Copper block designed as flat surface block, enabling easy resurfacing and thus giving extended life time of mould.
Standard Size of Coin Sample : 39 - 40 mm Diameter, 4 -5 mm Depth
Instructions to use:
The die should be fixed with a C-Clamp prior to pouring metal in it.
A bucket full of water needs to be kept next to the die before pouring metal in it.
Pouring of metal needs to be done till only 50-60% of the neck that is visible on the top of the die when clamped.
After pouring metal in die, it needs to be placed immediately in the bucket of water along with the C-clamp.
Once the die cools down for 4-5 minutes inside the bucket, then first remove C-clamp and then open the die.
The coin sample will be loose enough to come out on its own.
If the coin sample is stuck then apply very light force on the neck side of the die to remove the sample.
Once sample is removed break the neck and then use the Sample holder to polish the sample on the Spectrometer Polishing Grinder.
