CMT Materials PROTOBLOCK Air Permeable Prototype Tooling Material
Categories: Polymer; Thermoset; Epoxy

Material Notes: PROTOBLOCK is a new composite material made of inorganic granules and epoxy resin engineered to form a micro-porous structure for use as prototype vacuum form or thermoform tooling. The material is air-permeable over the entire surface allowing for unique design considerations for prototype tools. PROTOBLOCK is a cost effective alternative to other permeable materials when considering short duration runs.

    Advantages
  • High Definition and Accuracy
  • Improved Surface Quality
  • Trapped Air Elimination
  • Faster Air Evacuation
  • Reduced Machine Time
  • Improved Mold Detail

PROTOBLOCK may also be used in vacuum clamping divides. Even clamping is attained without the need for drilling. Since there are no drill holes or channels, even sensitive parts show no deformation. Static jam while ejecting can be eliminated using compressed air, which creates a smooth and even air cushion.
