Porosity: conventional 20% → 5%
Conventional Technology
Example of application for the oil cooling process using a tray for metal heat treatment
・Although it does not show infiltration of cooling oil, it is severely deformed in a high-temperature environment due to being metallic, its manufacturing process is difficult to automate, and its life is short.
・As it is heavy-weight, heating and cooling take time, leading to high energy consumption.

New Technology
・As porosity is low and cooling oil is not penetrated, it can be used for oil cooling process.
・Since it is made of carbon, it has excellent heat resistance capabilities, will not be deformed, and its manufacturing process can be automated.
・As its density is 1.7 g/cm3 which is approximately a quarter of metal, it is light-weight with low energy consumption.
