Product Overview
With diverse applications for industrial apparatus or equipment, demand for heat-resistant structure materials has been increasing.
Ryoden Kasei commercially produces “MIOLEX”, a material free from asbestos, which has been highly appreciated by users. With further research and improvement, our “MIOLEX Series” now provides an extensive product line-up.
MIOLEX Series features excellent heat insulation characteristics and mechanical strength, good size stability, outstanding cost performance, the safety of being asbestos-free, electrical insulation characteristics, machinability, etc.
This product fits the environmental measures demanded in recent years because its use leads to advantages such as energy saving and yield improvement.
Energy saving effect as a heat insulating material
By using our heat-resistant structural material as a heat insulation board, the amount of heat dissipation from manufacturing equipment can be decreased, and a great energy saving effect can be obtained.
It shortens the temperature rise time at the beginning of operation and reduces material losses during test operation.
As shown in the figure below, with a metallic mold temperature of 140℃, the energy required for heating the metallic mold decreases by about 40% as compared with using no heat insulation board.
The time needed to reach the set temperature is also improved, by about 20%.
Use of a heat-resistant board provides further advantages, such as increasing the uniformity of temperature distribution in the metallic mold, and controlling heat conduction to the molding machine. Consequently, it is possible to prolong the life of both the metallic mold and the molding machine.
Energy saving effect with heat-resistant board
Test machine: 80 ton injection molding machine Metallic mold size: 380 x 320-340 (H) Setting temperature of metallic mold: 140℃ (heated by cartridge heater)
