Surface preparation
The quality of the bonded joint begins long before the adhesive is applied
For each bonding, it is necessary to verify the material, surface condition,
previous technological steps, cleanliness, compatibility of the adhesive and the
required load of the joint. An error in surface preparation often becomes apparent
later in bonding, which is why we address it as a key part of the job.
Depending on the type of part, the process may include degreasing, grinding,
roughening, masking, surface activation, priming, or a trial run design before
repeat production.
Material and surface condition
We assess whether the surface is suitable for bonding, what kind of preparation it
requires and whether grease, oxidation, older treatment or inappropriate handling
interfere with the result.
Degreasing, roughening and activation
Proper surface preparation helps improve adhesion and joint stability. We choose
the specific procedure according to the material, glue and the requirements of the
order.
Masking and accuracy of application
For technical parts, we solve the exact definition of the bonded surface, the
protection of the surrounding parts and the cleanliness of the application so that
the joint corresponds to the technical specifications.
Test procedure before repetition
For repeat orders, it makes sense to verify the procedure on a sample or first
part. This will help set up preparation, application, curing, inspection and
documentation prior to serial pass.
