Measuring Dry Flow is the single most common method to determine powder ‘quality’ Dry flow is the measure of how a powder will tumble and flow in the mould during the rotational moulding process. The dry flow affects the heat transfer in the powder pool and how the powder distributes itself over the mould surface. Dry flow depends mostly on the particle shape, and to a lesser extent particle size. Particles that have been ground poorly will have ‘tails’ and tend to be ‘fluffy’. These two characteristics will give the powder poor flow properties - possible leading to uneven wall thickness, bridging across narrow recesses and a high void content within the moulded product. Having the ability to identify significant variations in powder quality can minimise unsatisfactory moulded products. New global standard for Dry Flow Funnel Fabrication
