Ensuring Sublime Surface Finish with Moisture Analysis

Good Moisture Analysis Practice (GMAP) is a recommendation tool that takes into account the customer process (risks, sample characteristics, measurement tolerance) and recommends the best-suited instrument for moisture analysis, including user training, service, routine testing and test frequency.?

The right moisture content of polymer resins ensures trouble-free compounding and injection molding, resulting in a smooth surface and ideal characteristics of the injection-molded parts.

Why analyze moisture?

Moisture control is a key determinant of the quality in industries manufacturing plastic parts via injection molding. The company has been producing a broad range of plastic parts through a similar molding process but was unable to achieve consistent smooth surfaces and good mechanical properties of the parts. The uncontrolled moisture in raw plastic pellets was found to be the prevailing issue. Their quality control lab had implemented Standard Test Method (ASTM D6980-17) for “Determination of Moisture in Plastics by Loss in Weight” to ensure quality and compliance with industry regulations. Looking for solutions, METTLER TOLEDO’s GMAP based recommendation introduced them to the HX204 Moisture Analyzer owing to its measurement performance and ease of use. The HX204 Moisture Analyzer ensures error-free operation with minimal training and non-reliance on chemicals.

A “no-brainer” choice for moisture analysis

The state-of-the-art technology makes HX204 an outstanding choice amongst conventional moisture analyzers. With high efficiency, HX204 is the best solution that provides accurate results for all sample types, due to fast halogen heating and superior weighing performance with 0.001 %MC readability.

For optimal process control and optimized productivity, it is possible to define multiple users with individual access rights to adhere to SOPs and regulations. Customizable control and warning limits for each method allow instant pass/fail decisions. The user can print data or transfer it via network connection to a PC or network printer to avoid transcription errors and increase productivity.?

Thanks to the embedded QuickPredict? software function, the operator can predict the final result of moisture measurements in a fraction of the usual measurement time.?

Moreover, the integrated routine testing features ensure the instrument is always performing optimally.
