Injection moulded parts’ cycle times are often determined by the size of the sprue, as it can be the thickest section of a part. As Lomold has no sprue, cycle times can be considerably faster. Long glass is able to conduct heat from the molten polymer more efficiently than short glass – this effect is enhanced as glass fibre loadings are increased. Another factor that plays a large part in injection moulding is the filling time – this determines the temperatures at which moulds can be run and influences cycle times with less shear than conventional injection moulding. Lomold’s filling time is up to 60% quicker, allowing lower mould temperatures and subsequent cycle time reductions. While packing of the part takes place, Lomold is able to recharge for the next shot, meaning that there is no lag between ejection and preparation for the next shot.
