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.

The design of a plastic cup mould is a specialized field of toolmaking that balances intricate detail with the demands of high-speed, automated production. Every feature of the final cup, from its rim curl and base geometry to subtle branding textures, must be precisely machined into the mould steel. Moulds are commonly made from pre-hardened steels like P20 or H13 for good polishability and...
