Plastic cup mould incorporates stacking rings that allow cups to nest securely for transport. The mould cavity shapes a tapered body with support ledge for stable stacking during use. A functional plastic cup mould creates rim geometries that interlock without sticking together tightly. Stack strength must be sufficient to hold filled cups without collapse during palletizing. Logistics efficiency improves when cups stack reliably for distribution and retail display. Space utilization is optimized through consistent nesting properties.

Rim design in a plastic cup mould affects both sealing and stacking performance simultaneously. The lip geometry must accept lids while providing stacking support below the rim. A versatile plastic cup mould produces cups compatible with standard lid systems used in food service. Dimensional precision at the rim is critical for both functions to work properly. Multiple requirements must be balanced in the mould cavity design.

Ventilation features in a plastic cup mould for nested cups prevent vacuum lock during separation. Small ribs or bumps on the cup sidewall create air passages between nested units. A practical plastic cup mould includes de-nesting aids that allow cups to separate easily. Sticking between cups would slow filling line operations and reduce productivity. User convenience is enhanced through thoughtful de-nesting features.

Plastic cup mould surface finish affects cup clarity and release properties for transparent designs. Highly polished cavities produce clear cups for cold beverage service. Texture can hide flow marks in opaque cup applications. Finish selection depends on the intended end use of the finished cups. Surface quality directly affects product appearance and customer acceptance.
