Plastic bottle caps are used in diverse industries. They are used in food, beverages, pharmaceuticals, and medication. The production of such cap involves a process called injection moulding.
Injection moulding is a cost-effective procedure, and it's ideal for high-volume production runs. However, it's not the only choice for producing caps. Compression moulding is also a good option. This technique is less costly than injection moulding, and it offers a better experience.
To produce plastic bottle caps, the process starts with the injection of soft thermoplastic polymer pellets into a steel mould. After being injected, the polymer material is heated and cooled to form a shape.
When the polymer material is hardened, the mould is opened. Bottle caps are then carefully separated from the mould and prepared for further processing.
Injection moulding is a common bottle cap manufacturing process. It is an effective method for producing parts that can withstand tight tolerances.
The cost of producing a bottle cap depends on its design and its material. Caps with high-density polyethylene reduce weight. Their rigidity makes them perfect for fast cycle production.
Thermoplastic polymers are expensive, and this can increase the cost of producing a cap. However, they are long-lasting and provide excellent protection against mechanical stress. Also, they improve the flexibility of bottle caps.
Choosing a good bottle cap mould is important to ensure smooth moulding and reliable inspection. A skilled technician should be involved in the production of the cap.
