Bonding

Medical devices are often comprised of several different components, which may require bonding. Bonding in medical device manufacturing involves the use of a substance or agent which causes two or more parts or objects to adhere. The joining may be of similar or dissimilar materials, which may require different surface treatments before bonding.

Contract manufacturers who provide bonding services for medical devices may also need to prepare, pretreat, and even post-treat surfaces to ensure bonding. Surface preparation involves cleaning and degreasing, as well as deburring the substrate’s surface. Mechanical processes (such as grinding) or chemical processes (such as etching in metals or gas-phase fluorination in plastics) may be necessary to alter the structure or chemical composition of the surface before bonding. Post-treatment covers any techniques that preserve the treated surface, such as applying a primer.
