Description

Stacking mould is famous for its high productivity. Different from the conventional mould, cavities in stacking mould are located in two or more levels, and be overlapped arranged, which is equivalent to a multiple stacked mould. It is mostly used for small, shallow stretch packaging products and other disposable products. Stacking mould can use cold runner, or hot runner. When using a cold runner, you need to consider the amount of materials used in feed system condensate. When using hot runner, that is no feed back condensate production. The materials in the hot runner plate and the center main nozzle will not affect the required injection amount.
