Models/Plastic & Resin Model Kits



Most model kits are made of plastic and some are made of resin.  What is the difference? The resin kits seem to cost more.

I thank you for your reply.

The biggest difference besides the material ey are made of is how they are made.  Plastic kits are injection molded, softened plastic is injected into metal molds in high pressure, then allowed to cool before demolding.  Resin kits are poured into RTV silicone molds. The resin is a two part system that only sets when the two parts are mixed together.  

Another big difference is that plastic kits are built using a glue that welds the two plastic parts together, while resin kits must have their parts mechanically adherded to each other with cyanoacrylates or epoxy cements.
