Insights into Masking Across Industries and Applications

In today's competitive manufacturing landscape, precision finishing processes are essential for product quality, performance, and aesthetics.

Across diverse industries—from automotive and aerospace to medical and electronics—masking plays a pivotal role in ensuring that coatings, treatments, and finishes are applied exactly where needed and nowhere else.

Automotive Industry Masking Applications

Powertrain Components

Engine blocks, transmission housings, and drivetrain components often require selective coating or treatment:

• Threaded Connections: Engine blocks contain numerous threaded holes that must remain coating-free to maintain precise tolerances.
• Gasket Surfaces: Sealing surfaces must remain uncoated to prevent leaks.
• Bearing Surfaces: Areas where bearings will be installed require exact dimensional tolerances.

Brake Systems

• Caliper Pistons and Bores: Piston bores must remain uncoated to maintain proper function.
• Hydraulic Connections: Brake fluid passages require complete protection from contamination.

Aerospace Industry Masking Applications

The aerospace industry demands the highest levels of precision and reliability.

Engine Components

• Cooling Passages: Turbine blades contain intricate cooling passages that must remain unobstructed.
• Bearing Surfaces: Engine bearing surfaces require exact tolerances maintained to microinch specifications.

Electronics Industry Masking Applications

Circuit Board Protection

• Conformal Coating Masking: Connector pins and test points must remain coating-free.
• Wave Soldering: Certain areas must be protected from solder contact.

Connector Manufacturing

• Contact Plating: Connector contacts often receive precious metal plating only on specific surfaces.
• Housing Protection: Plastic housings must be protected from chemical exposure during plating.
