Turbine Volute Moulds are commonly used in a variety of industries. If you are unable to find the one that suits your needs, please feel free to contact us and let us assist you with the process. We are more than happy to answer all of your questions.

The main difference between an open and closed nozzle is the number of openings on the nozzle. The former allows for minimal pressure drop, eliminating hold-up points. However, it can lead to leakage in low-melt viscosity materials. To avoid this problem, you should opt for a shut-off nozzle. This option will not cause any leakage during the screw-back part of the molding cycle.

The shape of the volute is defined by its angle of expansion, which corresponds to the angle formed between the tangent to the volute and the circle that passes through the point of rotation. The angle of expansion is relatively uniform and allows for a regular increase in the distance between the outer section of the blades and the inner face of the peripheral wall. Depending on the shape of the turbine, the outer section of the volute can be either radial or tangential.
