Plastics (extruder/injection molding)

The products on this page were specially developed for plastics industry applications, such as:

  • Extruders (resin pressure & temperature control)
  • Injection molding (mold temperature verification & control)
  • Hot runners (temperature control of many controlled heating zones)

Dedicated sensors for resin pressure & temperature

Resin temperature sensors

The T-270Z series resin temperature thermocouples are specially designed for high accuracy resin temperature measurement in extruders.

  • suitable for high accuracy measurement of resin temperature in extruders
  • zero heat flow measurement method eliminates thermal disturbance and temperature error between tip and case. This enables a more precise resin temperature measurement
T-270Z extruder resin temperature sensor
Measures at the tip and not the case: more accurate resin temperature measurement

Resin pressure & temperature sensors

The CZ100P & CZ200P series resin pressure & temperature transducers are specifically developed for extruder applications.

  • CZ-100P: resin pressure only transducer
  • CZ-200P: resin pressure & temperature transducer
Measure resin pressure & temperature accurately

Dedicated sensors for mold temperature

The temperature of the mold must be monitored to verify if it has the correct process-temperature. Sometimes the available measurement space is very small. RKC developed the ST-50/ST-51 ultra-compact film-type temperature sensors that can be easily attached to the mold with the STM-A magnetic holder.

  • suitable for accurate measurement of mold temperature
  • sensor type: type K thermocouple
  • temperature range:
    • ST-50: 0°C to +300°C
    • ST-51: -40°C to +300°C
STM-A magnet type temperature sensor
Easy attachment to the mold with the STM-A magnetic holder

Handheld thermometers for resin temperature verification

Discharged resin temperature check

The temperature of the discharged melted resin can be checked. This can lead to quality improvement of the process.

Dedicated fast and accurate resin pressure & temperature controllers
