DYNISCO

Dynisco

Dynisco was founded in 1953 and has long been providing tools and services for the polymer industry. Their goal is to give customers a “window into the process” – a direct and reliable insight into the process, enabling production to be verified and, when necessary, quickly adjusted to ensure the output meets the required specifications.

Practical benefits

Today’s manufacturing requires accurate data both for quality verification and for stable process control. Dynisco focuses on measuring and evaluating parameters that directly affect process consistency – especially pressure, temperature, and the rheological properties of the melt.

Dynisco’s portfolio includes a wide range of sensors and measuring equipment for production environments, as well as laboratory instruments for polymer testing. By connecting data from pilot and laboratory measurements with online production monitoring (24/7 depending on configuration), changes can be addressed quickly and the process can be maintained within target parameters.

  • Early detection of deviations (trends and process changes) and rapid parameter correction
  • More consistent quality across batches and improved production repeatability
  • Reduced downtime and scrap rates thanks to better process control and fast diagnostics

Portfolio: measurement, analysis, control

Dynisco is globally recognized for products for pressure and temperature measurement and control as well as solutions for polymer testing and rheology. Typically, this involves a combination of sensors, indication/control units, and laboratory instruments for verifying both the material and the process.

Sensors and process measurement

Robust sensors and transmitters designed for demanding polymer processing conditions such as extrusion or injection molding. Variants are available with different output signals and interfaces, including widely used industrial signals (e.g., mV/V, mA, VDC) as well as versions compatible with HART. 

Analytical instruments and polymer testing

Process quality starts with the material. Dynisco provides tools for verifying material specifications and optimizing processing conditions – from laboratory testing to online measurement (depending on configuration). 

  • Capillary plastometers (Melt Flow Indexers)
  • Capillary rheometers
  • Laboratory mixing extruders 
  • On-line rheometers for continuous melt monitoring
