In the packaging industry, the design and production of caps play a vital role in product usability and consumer satisfaction. Two of the most common types of caps are flip-top caps and screw caps, both manufactured using specialised Cap Moulds. Understanding the differences between flip-top cap moulds and screw cap moulds can help manufacturers and suppliers select the right tooling solution for their product requirements.

A Cap Mould is an essential tool used in injection moulding to shape plastic caps. The design of the Cap Mould must precisely reflect the desired cap style, dimensions, and functionality. Flip-top cap moulds and screw cap moulds differ significantly in their structural design, manufacturing process, and applications.

Flip-top cap moulds are designed to create caps with a hinged lid that snaps open and closed. These caps offer convenience and easy access, making them popular for products like shampoos, lotions, and condiments. The Cap Mould used for flip-top caps is more complex compared to screw cap moulds, as it must form the hinge mechanism and the snap-fit features that ensure the lid stays securely closed when not in use.

On the other hand, screw cap moulds produce caps with threaded designs that twist onto the bottle neck. These caps provide a reliable seal and are widely used for beverages, pharmaceuticals, and chemicals. The Cap Mould for screw caps focuses on creating accurate threading and a smooth finish to guarantee compatibility with corresponding bottle threads. Precision is crucial in screw cap moulds to ensure leak-proof performance and ease of opening.
