What Causes Cavity-to-Cavity Variation in Multi-Cavity Moulding?

Multi-cavity moulds are designed to produce multiple components in every injection cycle. Intheory, each cavity should receive the same material, experience similar processingconditions and produce parts with consistent dimensions and appearance. In practice, however, cavity-to-cavity variation can occur even when all cavities are part ofthe same mould and the machine is operating under the same […]
