Plastic cup moulds are essential tools in the production of disposable or reusable cups used in food service, beverages, and packaging. Choosing the right mould type ensures efficiency, consistent quality, and cost-effective production. Several types of moulds are commonly used in the industry.

Injection Moulds

Injection moulds are widely used for producing rigid plastic cups, such as PP or PS cups. In this process, molten plastic is injected into the mould cavity under high pressure. Injection moulds are suitable for high-volume production and provide precise shaping, smooth surfaces, and uniform wall thickness. They can also produce complex designs, including textured surfaces and integrated handles.

Thermoforming Moulds

Thermoforming moulds are used to produce plastic cups from heated sheets of plastic. The sheet is heated until pliable and then shaped over or into the mould cavity using vacuum or pressure. Thermoforming is ideal for producing lightweight, thin-walled cups for cold beverages or food products. This method allows for rapid production and is commonly used in large-scale manufacturing.

Blow Moulds

Blow moulds are used to produce hollow plastic cups or tumblers. In blow moulding, heated plastic is inflated into a mould cavity using air pressure. Blow moulding is suitable for cups requiring uniform thickness and strength while keeping the weight low. This method is often applied to polypropylene or polyethylene cups for industrial and beverage purposes.

Multi-Cavity and Specialty Moulds

Multi-cavity moulds allow several cups to be produced in a single cycle, increasing efficiency and reducing production costs. Specialty moulds may include features like stackable designs, measurement markings, or unique shapes to meet specific market requirements.

Plastic cup moulds include injection, thermoforming, blow, and multi-cavity or specialty designs. Choosing the appropriate type depends on the material, cup design, and production requirements, ensuring consistent quality and efficient manufacturing.
