The Injection Barrel Thermal Cover is an innovative solution designed for the barrel heating system of injection molding machines. Featuring a multi-layer insulation structure, it significantly reduces heat loss, improving heating efficiency and cutting overall energy consumption by more than 30%. The outer surface temperature is kept below 40 °C, creating a safer and more comfortable working environment. Optional fan integration enhances air circulation, preventing overheating and material carbonization for a more stable production process.
