Moldmaking Tutorial: 2 Piece Scale Model Car Mold


In this tutorial we mold a diecast car body using Gel-25. PlatSil Gel-25 cures to an A25 in about 1 hour so it is great for fast 2 piece molds. Gel-25 is very low viscosity so it is ideal for quick molds and does not require degassing for most applications. The final model car body was cast in EZ Flo 60 casting resin with yellow PolyColor added. There are several PlatSil Silicones that would work well for this process: 73-20 (for really small fast molds), 73-25 (For larger 2 piece molds that require a longer pour time), or 73-15 (for small 2 piece molds or cut block molds). All of those options may be used without vacuum degassing. If you are going to be pressure casting, vacuum degassing is a must! Under pressure micro bubbles can expand or contract causing surface imperfections in the final resin cast.

The mold in this video required about 5 lbs of PlatSil Gel-25. You can find Gel-25 in 2lb kits or larger on our webstore:
