Casting Mold Coating

What is TRABO Spray? 

TRABO™ Spray was inspired by REL Inc.’s development for NASA’s return to flight effort. It was initially developed into a spray mold coating to manufacture an intricately cast high pressure gas storage tank and Loukus Tech is now deploying TRABO™ spray in many new and innovative applications. When applied, this insulative spray is a coating with a wool-like feel and appearance. TRABO™ spray is a non-wetting spray which creates an airgap and keeps the metal from sticking to the mold or losing heat to the mold. TRABO™ is an order of magnitude more insulative than products on the market today.

TRABO Advantages 

  • Applicable for gravity, low, and high pressure casting 
  • Insulative coating: aluminum, magnesium, and steel casting 
  • Reduction of casting defects with thermal management 
  • Increased savings by reducing scrap and remelting costs 
  • Enables lower process temperature for metal and molds 
  • Effective launder and transfer ladle coating 
  • Cost effective coating solution
  • Spray-on application
  • Long shelf life 
  • Easy clean-up 

Coating for Squeeze Casting 

With pressure casting (i.e., squeeze casting or high pressure die casting, the flow of melt into tight areas of the mold is enabled with TRABOTM spray. Upon pressurization, the metal defeats the TRABOTM coating and solidifies at the same rate as bare steel with no coating. This allows for a shorter cycle time and fast solidification which is directly related to better mechanical properties.
