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.
Talc powder is used to lightly dust Mold Max® 60 molds in order to reduce surface tension
Reducing surface tension enables the molten metal to flow evenly around the mold surface
Talc is evenly brushed into all areas
Excess powder is removed by tapping the mold on the table top.
An airhose is used to eliminate any accumulation of talc in details. This leaves a very fine coating of talc in the mold
Pewter ingots are deposited into the melting vessel
The melting vessel is placed on a heat plate.
The heat plate is adjusted to 550F/290C
The pewter ingots begin to melt.
Once completely melted, the pewter is liquid.
The hot liquid pewter is poured into a mold.
Before the pewter cools, another mold is filled.
After thoroughly cooling, the piece is demolded.
Perfect detail is reproduced in the final pewter casting.
Many castings can be created in a Mold Max® 60 mold.
