Unlocking the benefits of silicone masks
In the thermal spray industry, the masking method significantly affects the efficiency and quality of the coating process. Several types of masking are commonly used to protect areas from coating: tape masking, silicone masks, metal or ceramic masks and curable masking resin.
None of these methods is universal, so the choice of a masking method must be carefully considered. Factors to evaluate include process temperature, part geometry, abrasion from grit blasting and spray particles, coating coverage tolerances, thickness range, and many others…
Silicone masks offer numerous advantages, making them a preferred option for cost efficiency and productivity:
- High-Temperature Resistance: Silicone masks can withstand the high temperatures involved in thermal spray, ensuring they remain intact and effective throughout the process.
- Reusability: Unlike traditional masking tapes, silicone masks are reusable, reducing waste and lowering overall costs. Their durability allows for multiple uses, making them a cost-effective solution.
- Precision and Quality: Custom-moulded silicone masks fit specific part geometries, ensuring precise coverage and protection of areas that should not be coated. This results in improved quality and consistency in the finished product.
- Ease of Use: These masks are easy to apply and remove, streamlining the masking process and reducing labour costs. Their flexibility and custom fit also minimize the risk of errors during application.
- Enhanced Performance: Silicone's properties enable it to resist wear, abrasion, and oxidation, common challenges in the thermal spray industry. This robustness enhances the masks' performance and longevity, making them ideal for grit blasting.
- Ease of Maintenance: With the right silicone composition, the masks require no cleaning and can be reused immediately, saving time compared to metal or ceramic masks which require extensive maintenance and stripping.
- Complex Shapes: Silicone masks can be custom-made in any shape, with inserts added for rigidity where needed.
- Waste Reduction: Silicone masks generate less waste than tape. At EPS-TS, we can repair and reload your worn silicone masks, ensuring they never end up in the bin.
