Injection molding bottle cap is produced through the injection molding process, with high precision, good sealing, high production efficiency, variety of materials and other advantages, the following is a specific introduction:
High dimensional accuracy: the injection molding process can achieve high-precision molding, the dimensional error of the bottle cap can be controlled within a very small range, and can be perfectly adapted to the bottle body, whether it is the inner diameter of the cap, the outer diameter, or the height of the dimensions of the bottle cap can be accurately molded to ensure good versatility and interchangeability.
Excellent sealing: injection molded bottle caps can be accurately designed and manufactured sealing structures, such as sealing rings, threads and other parts, can effectively prevent the contents from leaking or outside air, water, etc. into the bottle, for beverages, pharmaceuticals, cosmetics and other products that need to be well sealed and preserved, it can be a good way to ensure product quality and shelf life.
Good appearance quality: during the injection molding process, the surface of the bottle cap is smooth and flat, and can present a high degree of finish.
High production efficiency: injection molding process is suitable for large-scale automated production, injection molding machine can be rapid cycle operation, can produce a large number of caps in a short period of time. Moreover, the injection mold has a long service life and low replacement frequency, which can reduce the downtime for mold change, further improve the production efficiency and reduce the unit production cost.
Variety of materials: A variety of plastic materials can be used, such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET) and so on. Different materials have different performance characteristics, such as PE material is soft and low temperature resistant; PP material has good rigidity and heat resistance; PET material has high transparency and high strength, so you can choose the right material according to different product requirements.
High design flexibility: injection molding process is convenient for complex structural design, can add anti-counterfeiting structure, anti-theft ring, easy-to-open structure, inner stopper and cap integration structure, etc., to meet the functional needs of different products, but also according to the needs of the brand to design a unique shape, to enhance the recognition of the product.
