How is a Metal Mould Created for a Silicone Rubber Mould?

To create a metal mold for a silicone rubber mold, you can follow these steps:

Make a mold prototype: Use a rubber silicone mold material to make a mold prototype of what you want. Make sure that the surface of the silicone rubber mold is smooth without air bubbles or other defects to ensure the quality of the final metal mold.

Prepare the mold prototype: Treat the silicone rubber mold prototype to ensure that its surface is flat and free of impurities. Trimming can be done with sandpaper, scraper, or other tools.

Make the mold shell: Make a mold shell from a suitable material (such as plaster, sand, clay, etc.) and secure the silicone rubber mold prototype in the mold shell. Make sure the mold shell completely wraps around the mold prototype without any gaps.

Melting metal: choose a suitable sheet metal material and melt it to a sufficient temperature. The exact melting temperature depends on the type of metal used.

Wait to cool: Allow the metal to cool and solidify in the mold shell. Cooling time depends on the type of metal used and the size of the mold, it usually takes a while to cool completely.
