Solvent bonding is a secure and cost-effective solution for assembling plastic components. However, if proper precautions are not followed, the solvents can cause internal stresses to release too quickly and manifest in the form of stress cracking.

Solvent bonding is a secure and cost-effective solution for assembling plastic components. However, if proper precautions are not followed, the solvents can cause internal stresses to release too quickly and manifest in the form of stress cracking.

Stress cracking is the number one reported failure among solvent bonded assemblies. Stress cracking can occur weeks after assembly, increasing the risk of escaped defect material.

Annealing the components prior to assembly releases these molded-in stresses in a slow, controlled fashion, which improves the parts' ability to resist cracking and increase performance.
