General design guidelines are:
- design for lap shear loads
- maximize the bonding surface; for instance, use a scarfed or a dovetail joint
- avoid stress concentrations at thick-thin sections
- ensure that there is sufficient venting.
Scarfed or dovetail joints should be relatively shallow, so that solvent entrapment is avoided. Entrapped solvent can cause crazing over time and lead to part failure. The parts should be molded with a minimum of internal stress. Alternatively they can be annealed or stress relieved prior to assembly. Gates should be located away from the areas to be bonded. Caution should also be exercised when working with "closed" parts, to avoid getting solvent trapped inside the part.
