Product description
The temperature of plastic melts can be accurately controlled in runner systems in the process of molding hot runner molds. Plastics can flow into all the die cavities in a more uniform and consistent state, finally obtaining parts with consistent quality. The part sprue for hot runner molding is high in quality, so hot runners can achieve low residual stress and small part deformation after demolding. Therefore, many high-quality products on the market are produced by hot runner molds.
With extremely high heat conductivity, high-temperature strength, creep resistance, wear resistance and relatively strong corrosion resistance, tungsten-molybdenum and its alloy materials are appropriate materials for manufacturing hot runner nozzles in injection molding machines and other kinds of injection molding equipment.
