The flow properties of a material can also be investigated using a spiral flow test. The melt is injected into a spiral mould cavity. The melt will freeze at a certain distance along the spiral charmel (spiral flow length) depending on the flow properties and cross-sectional thickness of the spiral. The raw material manufacturer usually gives these values as material specifications. [Pg.146]

Flow tests are run in an actual injection molding machine. Results are usually direct, tangible, and easy to interpret. Typically the flow length mold forms a part in the form of a graduated spirals. The flow length is measured and can be related to flow conditions in an actual production mold. Spiral Flow Length (SFL) data is used especially for comparing various resins for ease of fill [13]. [Pg.76]
