mo explains: possibilities and limitations of hot-air dryers
Hot-air dryers are suited to preheating and drying non-hygroscopic or slightly hygroscopic plastics. These attractively-priced systems use ambient air to dry plastics by carrying the surface moisture away, but without the use of desiccants. …
mo explains the four key drying parameters.
When drying plastics, you should always keep four parameters in mind – and each one has an impact on the other three. …
mo explains: The moisture content of the feed material has a significant impact on the reliability of processes and the quality of the end product.
When manufacturing plastics, it is essential to ensure that the moisture content of the feed material is just right. …
mo explains: “Dosing accuracy” can be defined in many ways, depending on the application.
Generally, the term “dosing accuracy” is used to describe how accurately a dosing unit achieves the target mass or volume. …
mo explains: Separately dosed materials need to be correctly mixed to ensure that plasticisation results in a homogenous output material.
The purpose of dosing and mixing is to combine multiple materials in the right ratio. …
mo explains: In the context of continuous gravimetric dosing, “loss-in-weight” systems work by weighing the entire dosing module – the dosing hopper and its contents, the dosing device and drive unit – and measuring the decrease in mass as the material is metered. …
