Before I get into how much your material may change during your dispense process, let me provide a quick summary of why it matters. As your plant temperature changes, your material temperature often changes. When material temperature changes, the viscosity changes. When viscosity changes, the end result of your dispense changes – and nothing good happens when your finished product varies. It causes rework, scrap, customer rejects and in some cases, early product failure. In this blog, we’re going to address the effects of material temperature only. There may be other factors affecting your material but they’re not going to be addressed here.
