Maximizing Rotational Molding Process Efficiency

CLEVELAND - Sept. 26, 2019 - PRLog -- Oven Temperature Data Logger Logs in Extreme Heat

CAS DataLoggers provided the oven temperature data logging solution for a supplier of raw materials used in the plastics rotary molding industry. This company offers a comprehensive technical support service to their customer base, and part of this service includes technical advice and assistance for maximizing the rotational molding process to increase customer production efficiency.


CAS DataLoggers provided the customer with a Grant OMK610 Oven Temperature Profile Data Logger ( along with a custom enhanced thermal barrier for effective heat absorption. Users connected four Type K thermocouples to the data logger to monitor the internal temperature of the molding tool when inside the curing oven. The thermocouples were wired to the inside of the mold tool to monitor the air temperature and crystallization point of the polymer material which is 180oC (356oF). This process monitoring aids their customer's QA processes and assists them in minimizing the curing time while ensuring that the product is not over-cured.


Designed for temperature and rotational molding process monitoring, the logger's six thermocouple inputs accommodated both Type T and Type K thermocouple probes and supported high sample rates up to eight samples a second, supporting fast process times. During production runs, the barrier's all-stainless steel construction formed a robust barrier for the data logger. For extended logging, the thermal barrier could be used to up to 250oC (482oF) for up to 20 minutes depending upon the size and volume of the oven cavity.

With each reading, the Grant ( data logger reported and stored the time and date onto non-volatile memory holding up to 260,000 readings of secure data. Being battery-operated and portable, the oven logger operated in stand-alone fashion. Users navigated the menus through the intuitive 3-button design via the integrated display, and these were also navigable via PC. The logger was able to be configured to start and stop recording automatically at user-set times and temperature levels to present the most accurate process overview.

Passing through the process along with the products, the logger created a temperature profile which gave users a detailed view of their heat curing process. For example, percentage cure results were shown on screen at the end of every run.


The customer can now optimize their process by reducing production cycle times while maintaining their high quality of production. This increase in yield reduces their manufacturing costs. In addition, using the included software, they are now able to document batch-to-batch thermal processing and print reports.
