Best for
Lightweight and dissimilar-material assemblies, composites and sealed joints.
Watch for
Surface prep and cure control are critical, and inspection of the bond is hard.

Design tips
A few general pointers for Adhesive Bonding. The full, part-specific DFM list is in the dossier.
Joint loaded in peel/cleavage.Redesign for shear.
Too little bond area.Add overlap.
Cost
What it costs
Joins dissimilar/thin materials, spreads load, seals; strong in shear, weak in peel. Surface prep is everything.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for your part at your volume, in your currency, are in the dossier.

Adhesive bonding joins parts with a structural adhesive that spreads load over the whole joint and can bond dissimilar materials. The typical route is: Surface prep; Apply; Fixture & cure; Inspect. Lightweight and dissimilar-material assemblies, composites and sealed joints.
What does Adhesive Bonding cost per part?
It depends on size, tolerance and volume. As a rough ballpark it starts around $5.0 to 8.4 per part at low volume and falls with quantity. The dossier gives should-cost at your exact volume and currency. Model estimates, not quotes.
What tolerance can Adhesive Bonding hold?
It depends on the feature and the finishing operations used.
What materials suit Adhesive Bonding?
Common choices are Epoxy (2-part) (Strong, structural); Cyanoacrylate / UV (Fast); PU / silicone (Flexible, sealing).
