1. The so-called runner free mold means that certain measures are taken for the mold to keep the plastic in the mold channel in a molten state, so that only useful products can be produced in each molding cycle, and no useless material handles (runner condensate, runner debris) will be produced.
2. Therefore, the mold without runner does not mean that there is no runner in the mold, but that the material handle will not be generated at the same time when making products.
3. Because the plastic in the flow channel is always in a molten state, the injection molding operation can continue smoothly.
