INDUSTRIAL FINISHING
Our masking products are used for powder coating, spray painting, electroplating, e-coating and anodizing. Material selection depends on process temperature, time and chemicals.
MASKING SELECTION
Start with the area to protect. Share its dimensions and finishing conditions so we can help you choose a suitable masking part.
Tapered, blind-hole and pull plugs protect internal openings. Match diameter, depth and thread requirements.
Choose silicone caps to cover external projections and pipe ends. Check outside diameter and required coverage.
Washer and flanged plugs cover a hole and its surrounding contact area. Define the coating-free face diameter.
Custom shapes and die-cut masking follow the area you need to protect. Send a drawing, sample or marked photo.
STANDARD & CUSTOM SERVICE
Choose a standard size for quicker supply, or send a drawing, sample or dimensions for a custom masking part. Custom tooling fees depend on size and shape; custom sampling takes about one week.
PRODUCT RANGE
Choose standard silicone plugs, caps and rubber parts for common openings, threads and projections. For critical fit or unusual geometry, request a custom masking part based on your drawing, sample or dimensions.
For selection, tell us the area to protect, process, curing temperature and time, material contact conditions and required quantity.
