In foundry industry, many products will appear in the process of die casting defects such as cracks, sand hole, bubble, which are related to mold temperature anomaly, the surface temperature of the mold directly affect the quality of the products mould processing, therefore, the mold surface temperature distribution in the test for the product process quality security and high efficiency of zero defect is of great significance for industrial production.

With the development of infrared thermal imaging technology, the hardware cost is constantly reduced, and it is more and more common to use infrared thermal camera to detect the mold surface temperature. Some characteristics of infrared non-contact temperature measurement also bring a lot of convenience for this work.

Infrared thermal camera is mainly used for mold temperature detection in the following aspects:

1. Detect or monitor the surface temperature of molds and processed parts

In the continuous production process, infrared thermal camera can effectively prevent various problems that may occur in the casting process. For example, due to unnecessary use of temperature regulation, compressed air, water-based lubricant, mold release agent, etc., the mold temperature in the processing process is too high or too low, which will have a bad impact on the quality of parts, mold service life, production cycle, energy consumption and maintenance costs.

2. Optimize the die casting process

In the mold spray before and after spraying, the infrared thermal camera can be automatically generated for each die casting cycle mold total radiation heat maps do save analysis, provide relevant mold of infrared image, get the detailed information of the mould thermal distribution so that the customers for the current process conditions are the most intuitive judgment, workers can be realized through the optimization of die spraying process of fast adjustment of mold temperature.

The infrared thermal camera can monitor the mold temperature in real time, and obtain the high definition infrared image, the supporting infrared analysis software is simple to operate, can further analyze the image, unwatchable can also set the temperature alarm, the occurrence of temperature anomaly timely notify the staff, widely used in all kinds of industrial production.
