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.

Features:

• 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.
