The Importance of a Runner Mould!

A runner mould is an important part of the moulding process. It is an insulating component that transfers heat from a heated manifold to the cavities of the mold. The runner also helps to control warpage and shrinkage.

These components can be manufactured by various companies around the world. There are many different styles of hot runners, varying in size, shape, and design. In some cases, the runner is thermally cooled and can be mechanically closed.

Hot runner systems allow for automatic part separation, allowing for more efficient production. This helps to eliminate waste and ensure better quality of the finished product.

They are used to reduce the overall time and cost of the injection molding process. They can be customized to fit a new mold design. Most manufacturers provide excellent support.

In order to get the best performance from a runner mould, it is important to select the right type of system. Some factors to consider include size, quality, manufacturing costs, and customer tolerances.

An externally heated manifold is a great choice for plastics that are sensitive to thermal changes. The system provides adequate heat transfer, and ensures a faster start-up.

Runners are also available with various gate styles. Heated tipped probes are placed behind each gate to control the filling of the individual cavities.

The size and shape of the runner can affect the part formed, its weight, and how the mold fills. As a result, the moulding process can be more reliable, as well as less costly.
