Vacuum Forming Tool Materials

MDF (Medium Density Fibreboard)

A wood-based material is often used for prototyping or low-volume vacuum forming moulds.

Pros: Inexpensive, easy to machine, great for quick turnarounds or testing form and fit.
Cons: Limited durability, not heat-resistant, wears quickly with repeated use or high temperatures.

Epoxy or Composite Moulds

Used for mid-volume production where lightweight tooling is needed.

Pros: Lower cost than aluminium, good surface finish, moderate durability.
Cons: Can degrade over time with heat and pressure, limited to specific applications.

Urethane/Tooling Board

A dense, machinable foam-like board used for short-run production or prototyping.

Pros: Easy to CNC machine, good surface finish, better durability than MDF, and can withstand moderate heat.
Cons: Still has a limited lifespan compared to metals, making it not ideal for long production runs.

Aluminium

A premium choice for high-quality, long-lasting vacuum forming moulds.

Pros: Excellent heat transfer, durable, supports high-volume production, resistant to warping.
Cons: Higher cost, longer lead time, requires CNC machining or casting.
