Mold heat insulation board is a kind of material used between the mold and other equipments, which plays the role of heat insulation. The following is a detailed introduction about mold heat insulation board:
The main role of Mold heat insulation board
Molds in the working process, such as injection molds, die-casting molds, etc., often come into contact with high-temperature plastic melts, metal liquids and so on. Mold heat insulation plate can effectively prevent heat transfer from the mold to the mold mounting platform or other equipment components. For example, during the injection molding process, the temperature of the mold may reach about 100 - 300°C. Without a heat shield, the heat will be transferred to the mold plate of the injection molding machine in large quantities, resulting in high mold plate temperatures, which will affect the performance and service life of the injection molding machine.
Energy saving
By reducing heat loss from the mold to the outside world (e.g. equipment such as injection molding machines), the mold itself is better able to maintain its temperature. This reduces the amount of energy used to heat the mold. In the case of hot runner molds, for example, the power required to maintain the temperature of the mold by the heating element can be reduced with the use of a heat shield, thus reducing production costs.
Improved product quality
For some plastic products or die-casting products that require high dimensional accuracy, it is critical that the mold temperature is stable. The mold heat insulation plate helps to maintain the uniformity of the mold temperature, making the product cooling or curing more uniform during the molding process, and reducing the product's deformation, warping and other defects. For example, in the production of high-precision optical plastic lenses, a stable mold temperature is ensured by the heat shield, which can improve the optical properties and dimensional accuracy of the lenses.
