Heat insulation panels are industrial-grade panels used to block heat transfer. They are made from a high-density, high-temperature resistant, inorganic composite flame-retardant substrate, pressed under high pressure. The core essence of heat insulation is reducing the overall thermal conductivity of the material. The panel is filled with numerous sealed micropores. When heat passes through the panel, it is transferred simultaneously through the solid substrate and the air within the pores: the solid substrate transfers heat via conduction, while the heat exchange process within the pores is more complex.
The product simultaneously inhibits three heat transfer pathways: conduction, convection, and radiation. Combined with the principle of heat shield reflection insulation, it comprehensively blocks the outward diffusion of high temperatures.
Blocking Heat Conduction: When metal molds are directly bonded to equipment mounting plates, heat conduction is rapid, and heat is easily lost. The heat insulation panel, sandwiched between the two, uses the low thermal conductivity composite substrate to cut off the solid heat conduction channels, firmly locking in the temperature of the mold cavity.
Reducing Heat Radiation: Special fire-resistant reflective filler is added inside the panel to reflect and absorb infrared radiation heat released from the mold, reducing heat radiation and preventing continuous overheating and damage to the machine tool frame.
**Insulation of Thermal Convection:** The dense, seamless sheet material prevents hot air from penetrating and facilitating thermal convection, reducing temperature loss at its source.
**Layered Gradient Buffer Insulation Structure:** The sheet material is formed using a multi-layered, integrated hot-pressing composite process. The stacked layers of insulation create a gradient temperature difference: the side closest to the mold maintains a high temperature, while the heat transferred to the machine tool side is significantly reduced after passing through multiple buffer layers. The greater the sheet thickness, the longer the temperature buffer attenuation range, resulting in superior insulation and energy-saving performance.
**Dual Working Logic of the Mold:** The insulation plate is typically installed between the mold fixing plate and the injection/die-casting equipment template. The high temperature generated during mold operation is significantly reduced in heat transfer to the machine tool body after being buffered by the multiple layers of insulation. This prevents heat loss from the mold interior, ensuring consistent product quality during mass production. Furthermore, it prevents the machine tool from operating in a high-temperature environment for extended periods, effectively protecting hydraulic components, guide rails, and other metal parts, delaying equipment aging, and reducing the continuous operation time of heating coils, thus lowering the overall energy consumption of the production line.
