Diecast (or die cast, or die-cast) is a general term used to describe the process of giving a defined shape into a mold to either molten metal (lead, zinc alloy) or plastic. Depending on the material used, the manufacturing processes differ.
In order to give a particular shape to molten metal, such as diecast model cars, one needs to inject it at a high pressure into a heavy and strong metal mold. This procedure is named injection molding.
For the plastic and depending on the properties of the material it can either be molten and injected into heavy molds or molten and poured with a dipper into a soft silicone mold. This is the process used to create scale model cars in resin.
DNA Collectibles has chosen to produce model cars in resin, mainly because this material favors the application of meticulous details, such as photo-etch parts and it allows very small production runs that makes your DNA Collectibles scale model a rarity.
Please have a look at this article “Alternatives to Diecast model cars” to learn more about the resin manufacturing process and its differences with the metal injection molding process.
Can we say that DNA Collectibles models are ‘1 18 diecast cars’?
Based on those explanations we can clearly say yes.
