The process of manufacturing plastic caps involves transforming plastic pellets into functional closures through injection molding.
This method uses high pressure to inject molten plastic into a precision mold, which then cools and solidifies into the desired cap shape.
Steps include designing the mold, selecting the appropriate material, injecting the molten plastic, cooling, and finally packaging the finished cap.
Here is an overview of how plastic caps are made, from raw materials to finished products.
The process of making plastic caps Design and mold preparation for plastic caps First, designers create a detailed blueprint of the cap, considering factors such as size, compatibility with the container, and user convenience.
This design then guides the creation of a mold-a tool that shapes the plastic. Molds are typically made of durable materials such as steel or aluminum to withstand the rigors of high-volume production.

Material selection and preparation Manufacturers select the appropriate plastic material, typically polypropylene (PP), because it is durable and chemically resistant. The plastic arrives in pellet form and is carefully dried to remove any moisture that could affect the integrity of the cap during the molding process.
Injection Molding Process of plastic caps The heart of manufacturing is the injection molding process. Here, dry plastic pellets are fed into the cap making machine, melted, and then injected into a mold under high pressure. The plastic fills the mold and forms the shape of the bottle cap.

Cooling and Ejection Once the plastic is injected, the mold cools, allowing the plastic to solidify into the shape of the bottle cap. After solidification, the mold opens and the bottle cap is ejected. This step is critical to ensure the structural integrity of the bottle cap.
Post-molding operations After ejection, any excess material or "burrs" are trimmed off. Some bottle caps may also undergo additional processing, such as heat treatment or the application of a liner to obtain a better seal.
