All About Moisture Analyzers

A moisture analyzer is a great tool for any plastic processor to have. It will tell you for sure that you are drying the material adequately. It is also a great tool for material suppliers to have so that they can aid customers who are trying to troubleshoot problems.

How exactly a moisture analyzer works seems like a bit of witchcraft. You put a bit of material in, you choose some type of program and hit the start button. Ten to twenty minutes later, the readout shows a percentage. The process is a little bit more complex than just heating the material and burning off the moisture weighing the sample before and after.

These two are not the same thing and if you specify an injection pressure range on your processing guides, you should only specify hydraulic pressure and you should be very clear about it.

James May: “Car makers charge a hefty premium for it, but it’s nothing more than a by-product of cheeseburgers. Maybe it’s time for us to move on.”
