Plastic cup mould produces disposable drinking cups for the food service and beverage industry. The mould contains multiple cavities that form cups in each injection or thermoforming cycle. A well-designed plastic cup mould incorporates cooling channels positioned for uniform temperature distribution across all cavities. Multi-cavity configurations ranging from 4 to 96 impressions maximize output per machine hour. Cup manufacturers meet high-volume demands from restaurants and stadiums through efficient mould technology. Production economics improve significantly with high-cavity mould designs.

Draft angle in a plastic cup mould allows easy ejection of finished parts without surface damage. Tapered side walls release cleanly from the core during the ejection phase. A properly engineered plastic cup mould balances draft requirements with cup capacity for each design. Wall thickness uniformity affects both part strength and material usage efficiency. Proper draft prevents sticking and cycle delays.

Gate location on a plastic cup mould affects fill patterns and visible witness marks on finished cups. Submarine gates allow automatic degating during ejection for high-volume production. A precisely placed plastic cup mould gate leaves minimal mark on the cup bottom or side wall. Hot runner systems eliminate runner waste while improving fill characteristics. Gate design must balance appearance with manufacturing efficiency.

Plastic cup mould steel selection prioritizes thermal conductivity for fast cycle cooling. High thermal conductivity materials pull heat from thin walls rapidly for short cycle times. Material selection directly impacts achievable production rates and part quality. Thermal performance is a primary mould design criterion for thin-wall cups. Cooling efficiency determines overall manufacturing productivity.
