Cap moulds are integral to the quality control process. Manufacturers often use moulds that incorporate advanced features, such as cooling channels or temperature control systems, to ensure the material solidifies evenly and that the final product meets the required specifications. These features also help prevent defects such as warping, cracking, or shrinkage, which can occur if the moulding process is not carefully controlled. Additionally, the moulds can be tested and calibrated to ensure they consistently produce high-quality caps that adhere to industry standards and regulations.

Types of Cap Moulds

Cap moulds come in several different types, each suited to specific applications and manufacturing needs. Here are some of the most common types:

Single Cavity Moulds

Single cavity moulds are used for small-scale production runs or for producing caps in limited quantities. These moulds have one cavity for making one cap per cycle. While they are less efficient for mass production, they offer high precision and can be used for customized or specialized caps that require specific features.

Multi-Cavity Moulds

Multi-cavity moulds are designed to produce multiple caps in a single cycle. These moulds have several cavities that allow for the simultaneous production of several caps. They are commonly used in high-volume manufacturing settings where large quantities of identical caps need to be produced quickly and efficiently. Multi-cavity moulds can significantly reduce cycle times and improve production efficiency.

Stack Moulds

Stack moulds are used for high-volume production runs and are designed to accommodate multiple levels of cavities, allowing for the simultaneous production of caps at different levels within the mould. These moulds can produce a higher number of caps per cycle compared to standard multi-cavity moulds, making them ideal for large-scale manufacturing.

Hot Runner Moulds

Hot runner moulds are equipped with heating elements that keep the plastic in a molten state as it moves through the mould, ensuring better flow and reducing material waste. These moulds are commonly used for the production of caps that require high precision, as they provide better control over the injection process and result in fewer defects.
