Heat flow is a heat transfer phenomenon that occurs between objects contacting directly with different temperatures. Heat insulation is the heat exchange reduction between high-temperature object and low-temperature one. Heat insulation can be achieved by changing the structure, shape and material of the heat transfer medium.
Mold thermal baffle is made of composite materials with low thermal conductivity, which is specially designed for the mold industry with heat insulation and compression resistance effect. Put thermal baffle between mounting plate and dead plate on the top of mold or between injection chassis and floating platen of injection molding machine to stabilize the temperature on mold cavity surface, ensure product quality, reduce heat loss and prolong service life by reducing mold heat transfer to mounting plate(the direction of transmission depends on the type of mold). As mold manufacturers demand higher production efficiency, energy conservation and emission reduction, thermal baffle becomes a necessary mold accessory for them, widely used in plastic mold, die casting mold, hot runner and other automation industry.
The outstanding material properties of good-quality thermal baffle are mainly reflected in the following points:
1. No asbestos, no harm to the environment.
2. Low thermal conductivity.
3. Strong compressive resistance.
4. Good mechanical and dimensional stability.
5. Low water absorption, good chemical stability.
6. Long service life.
7. Processable, customized and high-efficiency.
Through the application of mold thermal baffle, mold engineer can optimize production process and realize the purpose of energy saving, mainly reflected in the following aspects:
1. The percentage of energy saving is as high as 60%.
2. Uniform temperature distribution on cavity surface .
3. Reduced preheating and cycling time.
4. The thermal baffle won't be deformed and the service life will be longer.
5. Protect the equipment panel from high temperature damage.
