Enhanced TTV Die Cast Monitoring System

Marposs has announced improvements to its Total Thermal Vision (TTV) system, which uses infrared technology to monitor the surface temperatures of the die during the die casting process of light alloys. A completely new architecture provides a more compact system featuring an integrated, optimized cooling system, smaller electric shutters and compact connectors, as well as a smarter IR camera. Additionally, the use of a PLC is no longer required, providing more flexibility for customer configuration.

"The updated thermal imaging camera includes a high performance infrared camera housed in protective casing and thermally isolated from the surrounding environment, guaranteeing a perfect image of the die each time regardless of the installation distance," said a company spokesperson. The TTV control unit comes equipped with a 21.5" touchscreen with graphic interface and Marposs' E9066T Flat Panel industrial computer for data collection, measurement and control. It has up to four IR camera connections, and both the camera and controller units are specifically designed to operate in aggressive foundry environments.

"Correct temperature distribution on the die surface is crucial in guaranteeing the efficiency and quality of the die casting process," said the spokesperson. "Shrinking, porosity, cracking, blistering and a host of other defects may arise from an incorrect optimization of the thermal distribution on the die. The TTV system can be used in high and low pressure die casting as well as gravity die casting, helping users analyze, understand and improve their processes."

Thermal imaging cameras are easy to install inside the casting cells and are positioned to frame the die between the moment the newly produced die cast is removed and the preparation for the next cast. Cameras are equipped with acceleration, humidity, temperature and pressure sensors, which continuously monitor the operating state of the camera, offering precise, correct thermographic images regardless of the operating conditions.

TTV's overall benefits include:

  • Reduced process costs
  • Increased die lifespan
  • Optimized cycle times
  • Increased system efficiency (OEE)
  • Analysis of the process variables and errors
  • Reduced unscheduled process stops.
