Precision Hot Runner Mould
Hot runner mold refers to a mold that uses a heating device to keep the melt in the runner from solidifying. Because it has a shorter forming cycle than traditional molds and saves more raw materials, hot runner molds are widely used in developed countries and regions in the world today.
The hot runner system is generally composed of hot nozzles, manifolds, temperature control boxes and accessories. Thermal nozzles generally include two types: open thermal nozzles and needle valve thermal nozzles. Since the form of the hot nozzle directly determines the selection of the hot runner system and the manufacture of the mold, the hot runner system is often divided into an open hot runner system and a needle valve hot runner system accordingly. The manifold is used when a mold has multiple cavities or multi-point feeding, single-point feeding but the material level is offset. The material is usually P20 or H13. The manifold is generally divided into two categories: standard and non-standard, and its structure is mainly determined by the distribution of the cavity on the mold, the arrangement of the nozzles and the position of the gate. The temperature control box includes the host, cables, connectors and wiring male and female sockets. Hot runner accessories usually include: heaters and thermocouples, runner seals, connectors and junction boxes.
