Application overview

Making flexible molds with the Mayku Multiplier

Pressure forming with EVA material enables speedy, flexible mold creation for casting with other materials. This is beneficial for manufacturers across industries, as it enables them to manufacture flexible, shock-absorbent parts. Additionally, it facilitates the creation of intricate shapes and designs to meet specific product needs.

The key benefits of using the Multiplier:

  • Take full control of the prototyping cycle
  • Manufacture end-use or customized parts in-house
  • Reduce out-sourcing costs and lead time
  • Reduced tooling costs due to the elimination of the need for expensive molds
  • Use validated engineering materials for functional components
Application considerations

There are some key considerations when making molds with the Mayku Multiplier

Template design

We recommend using 0.75mm air holes, draft angles of at least 8º on all sides, and using a female mold for maximum detail

Template manufacturing

Manufacturing the templates with SLA 3D printing offers great flexibility and template quality for short production runs

Template smoothing

The Multiplier picks up all texture, so it’s recommended to clean up every detail in post-processing and smooth the surface to increase the final part transparency

Choosing EVA material

EVA is an ideal material for mold-making due to its flexibility, strength, and tear resistance

EVA part removal

Use scissors or a knife to trim away any excess material

Holding the mold in place

Consider adding self-aligning features to the mold and creating a fixture to firmly hold it in place, thus preventing leaks.
