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
- Reusable for multiple cycles


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
Masking Materials Available
- Plasma Grade Silicone
- HVOF Grade Silicone
- High Temperature Silicone
- Polyurethane (variety of grades)
- Special Resins

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
