PEEK (polyetheretherketone) material is a high-performance special engineering plastic that has become one of the key materials in the field of humanoid robots due to its excellent mechanical properties, heat resistance, chemical resistance, and lightweight characteristics.
Introduction of Mold Heat Insulation Board

2024-12
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.
Synthetic stone material in the reflow soldering tooling application

The temperature curve of reflow soldering includes preheating zone, constant temperature zone, reflow zone, and cooling zone, with a peak temperature generally between 220-240 ℃. Synthetic stone materials can maintain good performance within this temperature range without deformation, brittleness, or other issues. Its thermal stability enables the fixture to work stably during the heating and cooling cycles of reflow soldering, ensuring consistency and reliability in each welding process.
