Vacuum Casting or Injection Moulding? A Comprehensive Comparison

 In the world of manufacturing, two popular techniques often considered by engineers and designers are vacuum casting and injection moulding. Depending on project requirements, these methods offer different benefits and may serve various purposes. By exploring the strengths and limitations of vacuum casting and injection moulding, you can make a more informed decision for your production line.


Vacuum Casting – an Overview

Vacuum casting involves pouring liquid polyurethane into a silicone mould, which cures into a solid part. The master pattern for this mould is normally created using 3D printing or CNC machining, and can carry fine detailing. This method is widely appreciated for its quick turnaround times and is ideal for low-to medium-volume production runs. A tool or mould will typically deliver between 25 and 50 parts without compromising the end part.

The Versatility of Vacuum Casting

Your supplier will utilise your existing design files to create a master pattern through methods like CNC machining or 3D printing if the part has intricate detailing or is complex. A high-quality silicone mould is then created by encapsulating the master pattern with liquid silicone. Once cured, the mould is split open, allowing for master pattern removal.
