4 Cavity Plastic Container Cap Mould is a specialized mould used in the production of plastic caps for containers. These caps are typically made from various types of plastic materials, such as polypropylene (PP), polyethylene (PE), or polyethylene terephthalate (PET). The purpose of the mould is to shape the molten plastic into the final form of the cap, which is then used to seal a variety of containers like bottles, jars, and tubes.

These moulds are designed to produce caps with precise specifications, such as diameter, height, thread design, and seal performance, ensuring that the caps fit properly and function as intended.

One of the key features of the 4 Cavity Plastic Container Cap Mould is its ability to produce caps with high precision. The mould is designed with exacting tolerances to ensure that every cap is uniform in size and shape. This precision is critical because the caps must securely fit the containers to provide an airtight seal. Any slight deviation could result in poor sealing, leakage, or the inability to properly close the container.

4 Cavity Plastic Container Cap Mould are typically made from high-quality steel or other durable materials that can withstand repeated use and the high pressures involved in the injection moulding process. These moulds are engineered to last for thousands of cycles, ensuring cost-effectiveness for manufacturers who rely on high-volume production. The durable construction of these moulds reduces the need for frequent maintenance or replacement, thereby lowering operational costs.

Many modern cavity moulds are designed with multiple cavities to produce several caps simultaneously. This capability significantly increases production speed and efficiency. A mould with multiple cavities can help manufacturers meet high demand without sacrificing the quality or consistency of the caps being produced. This feature is particularly important for industries such as beverages, cosmetics, and pharmaceuticals, where large quantities of caps are needed in a short period.

Cavity moulds can be customized to produce caps with various designs, including different thread types, sizes, and shapes. This flexibility allows manufacturers to create caps that meet specific requirements for different products, whether it's a simple screw cap, a tamper-evident cap, or a child-resistant cap. Custom designs also allow for branding and aesthetic differentiation, which is especially important in competitive markets.

The mold has a short injection cycle, high efficiency, long life, and low cost.
Adopting the special flow channel design of the international advanced level, the cooling adopts circulating water to effectively improve the product demolding efficiency
The insert is made of S136 high-quality mold steel, and the steel hardness is HRC45-HRC48
The mid-term modulation treatment, tempering, and nitriding treatment make the tool parts have good comprehensive mechanical properties, high rigidity, and small deformation.
