Prototype Injection Molded Trays

If clients desire a prototype to be produced to check the fit and function of their injection molded tray, we at PolyFlex Products can develop rapid prototypes from a wide variety of processes and materials. Every prototype is a spitting-image of the end product, so clients know exactly what it is they will receive at the end of the development process and whether or not the original concept will work for their product.

Our processes include:

  • SLA (Stereolithography)
  • SLS (Selective Laser Sintering)
  • Cast Urethane
  • Fabricated plastic or wood models


SLS and SLA technology produce a solid prototype within hours. Made of powder (SLS) or liquid (SLA) plastic, the materials are sent through a 3D printer that takes the solid model concept and converts the electronic drawing into a physical object to create the prototype.

Cast Urethane

To test a wide range of material hardness for prototypes, PolyFlex Products uses cast Urethane. This type of prototype mold lets PolyFlex Products produce numerous samples at very little tooling cost.

Fabricated Models

If multiple adjustments to a prototype are needed, PolyFlex Products engineers can create a wood pattern of the reusable tray concept to run samples on. With wood, the engineers can easily and economically adjust the pattern during early phases of the design to verify outcomes of sampling.
