ProtoTech Machining Presents: Vacuum Casting – The Future of Precision Manufacturing

At ProtoTech Machining, we’ve always been at the forefront of leveraging advanced manufacturing techniques. Today, we’re delving deep into one such process that has been pivotal in transforming the industry landscape – Vacuum Casting.

What is Vacuum Casting?

Vacuum casting is a production technique often used for small quantities of functional plastic parts. It starts with a master model, typically created using stereolithography (SLA) or another additive manufacturing method. A silicone mold is then created around the master model. Once set, the mold is cut open, the master model is removed, and you’re left with a perfect negative of your part.

Why Vacuum Casting?

  1. Precision: One of the standout qualities of vacuum casting is the accuracy and detail it offers. It’s a matchless method for capturing intricate details and features of a prototype.
  2. Material Flexibility: From urethanes and elastomers to water-clear or filled compounds, the choices are vast.
  3. Cost-Efficiency: For small batch production, vacuum casting can be more economical than other traditional manufacturing methods, particularly when the tooling costs of injection molding are considered.
  4. Speed: From prototype to product, the turnaround time can be just a matter of days.
