The sealant looks set, but it isn’t fully cured. You ship it to test, and a week later the desiccant load shows moisture creeping back. Or worse, you see micro-cracks along the edge after handling, and the <a href="https://henruite.com">customer</a> is on the phone. That’s what happens when you treat curing like a generic “heat box” step. IGU sealing is a thermal process with tight tolerances. The adhesive or hot-melt has to crosslink completely, the primary and secondary seals need to bond cleanly to the spacer and glass, and the unit has to leave the oven at a uniform temperature so it cools without inducing thermal stress. If the oven can’t deliver repeatable, controlled heat, you pay for it in scrap, rework, and failures in the field. We built the controlled curing oven for IGU around a simple idea: control the heat where it matters—edge to edge, through the <a href="https://o-yate.net">entire</a> cure window—without scorching the glass or the sealant.</p>
