The use of a transvector (or so called venturi) allows you to control the wall thickness of your rotational moulded plastic parts – simply by increasing the heat on certain mould surfaces. The function is best described by the name „air-amplifier“. The transvector gets mounted some-where to the mould frame – the outlet aiming to the area an increased plastic wall thickness is desired. While the transvector uses compressed air you need to have an air-outlet on your machine arm. Connecting to the compressed air, it sucks the hot oven air (or cold air in the cooling chamber) and therefore amplifies the air stream. Pointing the increased air-stream to a certain area of the mould outside, this particular place heats up faster and forces the plastic to build up a thicker wall. (Of course a transvector also helps to cool certain areas).

To receive an even more effective heat increase of the mould wall you can run the compressed air through an spiral copper tube - so the cold compressed air heats up before it gets driven through the transvector. To be able to use a transvector with different moulds we offer a „Quick Connect“ which makes it easy to „plug-in and plug-out“ to the compressed air-hose (this Quick Connect is specially performed to be heat resistant up to rotational moulding conditions).

All sizes are made out of stainless steel and are adjustable to enable the use of different air pressures (from 2 to 6 bar) with almost equal efficiency. In addition the transvetor is fully dismountable - allowing easy maintenace or cleaning.
