Whether you’re a passionate collector or just entering the world of model cars and bikes, you’ve likely encountered two terms that dominate the hobby: diecast and resin models. But what exactly do they mean? What sets them apart? And most importantly, which one is better for you?
This in-depth guide will walk you through the origins, materials, pros and cons, and collector value of diecast and resin models to help you make an informed decision.
What Are Diecast Models?
Diecast is a manufacturing process where molten metal, typically a zinc alloy, is poured into a mold under high pressure to create model parts. The term “diecast” became popular in the early 20th century and was initially used to make toy cars, airplanes, and trucks.
Today, diecast models are known for their durability, realistic features, and mass appeal.
Materials Used
- Zinc alloy (sometimes with small plastic parts)
- Painted with enamel or acrylic finishes
Features
- Functional parts: opening doors, hoods, and trunks
- Working steering and suspension on premium models
- Often includes interior detailing
🧪 What Are Resin Models?
Resin models are crafted from polyurethane resin using a casting method that involves pouring liquid resin into silicone molds. The process allows for extremely fine detailing, which is why resin models are favored by high-end collectors.
Materials Used
- Polyurethane resin
- Often hand-painted or airbrushed
- Sometimes mixed with photo-etched metal or decals for finer details
Features
- High accuracy in shape and proportions
- Usually no moving parts
- Typically released as limited editions
