The main function of the coffee cup lid mould is to mold thermoplastic materials into coffee cup lids with specific shapes and sizes through the injection molding process. In order to achieve rapid production, coffee cup lid moulds usually adopt a multi-cavity structure design. This means that one mold can produce multiple coffee cup lids at the same time, thereby greatly increasing production speed and output.

At the same time, the material of the coffee cup lid mould needs to have good thermal stability, wear resistance and corrosion resistance to ensure the stable performance and service life of the mold during high-speed production. Commonly used materials include high-performance steel, nickel-based alloys, etc. In the injection molding process, rapid cooling is the key to improving production efficiency. The coffee cup lid mould needs to be equipped with an efficient cooling system to ensure that the coffee cup lid can quickly cool and come out of the mold after molding.
