Metal Adhesive Bonding and Adhesive Joining

Request more Information

Through the process of metal adhesive bonding and adhesive joining services, photo-etched parts are joined into simple or complex assemblies. Adhesively bonded components can be manufactured from titanium, copper, aluminum, brass, iron-nickel alloys, and Kapton, are suitable for medical, aerospace, filtration, automotive, and defense applications. Adhesive bonding enables bonding of chemically etched parts without mechanical fasteners, which in turn enhances surface finish and appearance of the bonded components.

Metal adhesive bonding joins similar or dissimilar metals and is suitable for irregularly shaped components. Little or no increase in assembly weight occurs in adhesive joining, and stresses are distributed evenly over the joined area.

To avoid contamination during metal fabrication, adhesive bonding operations are performed at VACCO’s in-house facility clean room, accredited to FED-STD-209 Class 10,000 standards. VACCO’s South El Monte, CA facility is also equipped with NVR (Non-Volatile Residue) and central laboratories to handle testing, pre-inspection, final cleaning, and sealing operations.

Problems Addressed with VACCO Adhesive Bonding

Many assemblies require joining methods that avoid distortion, fastener holes, or heat affected zones. Metal adhesive bonding helps solve challenges such as:

• Difficulty joining thin or delicate photo etched parts without damaging features.
• Limitations of welding or brazing when working with dissimilar metals.
• Need for smooth, uniform surfaces without visible fasteners.
• Stress concentrations caused by mechanical joining methods.
• Risk of contamination during assembly in sensitive applications.

Adhesive bonding provides a controlled, clean joining method that maintains part geometry and surface quality.

Advantages of Adhesive Joining

Adhesive bonding offers benefits that support both functional performance and manufacturing efficiency. Key advantages include:

• Even stress distribution across the bonded area.
• Minimal impact on part weight or thickness.
• Ability to join irregular shapes and complex geometries.
• Compatibility with metals and non metals, including Kapton.
• Clean, uniform appearance without fastener marks or weld seams.

These characteristics make adhesive joining well suited for precision assemblies used in demanding environments.
