How to set up a reasonable hot runner manifold

The hot runner manifold is a component that分流smelted material, which can transmit the molten plastic from the injection system of the injection machine to the mold cavity. Its function is to transmit the molten material to the gate, and under the conditions of friction, shear force and heating, the state of the molten material flow will not change as much as possible. Most suppliers process the runners to make hot runner manifolds by drilling holes on steel plates whose profiles have been initially processed, and then install heaters on the surface of the steel plate or inside the steel plate. In most applications, the hot runner manifold is designed with several heating zones controlled separately by thermostats.
