Reusable Silicone Masking for Thermal Spray



Basic Technical Advantages

Reusable Silicone Masking – custom design per part

  • Reduced (un)masking time, cost
  • Safe for part contact, no residue or cleaning
  • Improved quality and consistency

Material Suitablity

Material Considerations

  • High silica content – density and bounce factors
  • Special mixtures for harsh treatments like HVOF

Time vs. Velocity and Heat

  • Short exposure time, part cooling
  • Shaped to fit specific part geometry and spray angles

Freedom to Mix Materials/Components

Combining silicones or embedding reinforcements enables complex fitment


Material Customization for Process

Materials can be blended to suit process parameters, beyond category of spray


Mask Fitment

Elasticity and registration features improve security under process conditions


Integration with Fixturing

Mask design can integrate with metal fixtures
Silicone masking protects parts from metal contact

Advanced fixturing enabled by integration of silicone masking

  • Part-safe contact
  • Compliance allows for secure hold
  • Internal spray zones protected

Optimization

High-wear areas can be split into smaller consumable pieces


Induced Spray Effects

Mask geometry is essential to the spray area

  • Induce shadowing/feathering
  • Avoid shadowing, bouncing

Tricks to modify the way the materials behave

  • Modification of surface roughness
