Liquid Injection Molding

Liquid injection molding is similar to urethane injection molding but instead of melting pellets, the liquid is directly injected into a mold cavity.

Liquid injection molding is a way to produce parts for many uses. This molding differs from standard processes because it relies on elastomeric and liquid silicone rubber materials.

The versatility of this type of molding comes from the properties of the liquid urethane used in the process. We can provide coloring or transparency with this molding for the final part. This process is also useable for parts used as insulators or conductors because of the material used in manufacturing.


  • Reduced secondary processing
  • Produces more complex shapes


  • Tooling is more expensive
  • Looser tolerances
  • Part size is limited
  • Long cycles
  • A high amount of scrap
