Mold Max® 60 was developed for high-heat resistance applications and will withstand up to 560°F / 294°C. It features a low mixed viscosity and cured rubber exhibits very low linear shrinkage. Parts A & B are mixed 100A:3B by weight. Pot life is 40 minutes and rubber cures in 24 hours to a relatively hard Shore 60A.
Applications include making foundry patterns, flat pattern reproductions and casting low-temperature melt metal alloys such as tin and pewter.
This gallery will outline the casting of pewter into a Mold Max® 60 flat mold.
1 - Talc powder is used to lightly dust Mold Max® 60 molds in order to reduce surface tension
2 - Reducing surface tension enables the molten metal to flow evenly around the mold surface
3 - Talc is evenly brushed into all areas
4 - Excess powder is removed by tapping the mold on the table top.
5 - An airhose is used to eliminate any accumulation of talc in details. This leaves a very fine coating of talc in the mold
6 - Pewter ingots are deposited into the melting vessel
7 - The melting vessel is placed on a heat plate.
8 - The heat plate is adjusted to 550F/290C
9 - The pewter ingots begin to melt.
10 - Once completely melted, the pewter is liquid.
11 - The hot liquid pewter is poured into a mold.
12 - Before the pewter cools, another mold is filled.
13 - After thoroughly cooling, the piece is demolded.
14 - Perfect detail is reproduced in the final pewter casting.
15 - Many castings can be created in a Mold Max® 60 mold.
