Metal Casting

This guide introduces two practical methods for small-scale metal casting: sand casting and silicone-mould casting. It explains the essential principles of working with low-melting metals, including achieving the correct pouring temperature and avoiding gas absorption. Step-by-step instructions cover preparing moulds in silicone or casting sand, creating registration keys and pour channels, and safely melting and pouring metal using a controlled melting pot. The guide also outlines common tools and materials, troubleshooting considerations, and the limitations of each method. A summary of 4D Modelshop’s bespoke metal casting service is included for users who prefer professional production.
