In the modern packaging industry, the demand for wide-mouth containers has been steadily increasing. The KPET 1200-208 preform, with a 70mm wide mouth, 35g weight, and six-cavity design, represents a significant advancement in high-efficiency bottle production. With an optimized cycle time of 18.1 seconds, this preform is designed to meet the rigorous demands of industrial-scale manufacturing while maintaining consistent quality and precision.

Product Overview

The KPET 1200-208 preform is a specialized large-mouth bottle preform engineered for versatility and reliability. Its wide 70mm opening allows for easy filling and dispensing of various liquid and semi-liquid products, including foodstuffs, chemicals, and personal care items. The preform’s weight of 35 grams provides a sturdy base while optimizing material usage, making it both cost-effective and sustainable.

The six-cavity configuration of the injection mold enables the simultaneous production of multiple preforms, significantly improving throughput and reducing overall production costs. The cycle time of 18.1 seconds ensures a balance between speed and precision, providing manufacturers with the ability to scale operations without compromising quality.

Technical Parameters

Understanding the KPET 1200-208’s technical specifications is crucial for effective implementation in a production line. Key parameters include:

• Mold Configuration: 6 cavities 
• Cycle Time: 18.1 seconds 
• Mouth Diameter: 70mm 
• Preform Weight: 35g 
• Material Compatibility: PET, PETG, and other commonly used thermoplastics 

These specifications allow the KPET 1200-208 preform to serve as a foundation for a wide variety of container sizes and applications. The optimized cycle time ensures high productivity while maintaining uniformity across each preform batch.

Manufacturing Process

The production of KPET 1200-208 preforms utilizes a high-precision injection molding process. The process begins with carefully prepared PET resin, which is dried to eliminate moisture. This step is critical, as residual moisture can cause bubbles and defects in the final product.

The resin is then fed into the injection molding machine, where it is heated to a specific temperature and injected into a multi-cavity mold. The KPET 1200-208’s six-cavity mold allows simultaneous formation of six preforms, each with precise dimensions and uniform wall thickness. After injection, the preforms undergo controlled cooling to solidify the structure and ensure stability.

The mold cycle, set at 18.1 seconds, is optimized for maximum efficiency while minimizing material stress and potential defects. After cooling, the preforms are ejected and undergo post-processing steps such as trimming, inspection, and quality verification to ensure they meet stringent standards.

Material Considerations

The KPET 1200-208 preform is primarily designed for PET, a thermoplastic polymer widely used in beverage and packaging industries due to its transparency, strength, and recyclability. PET’s inherent properties make it ideal for forming wide-mouth containers, offering excellent chemical resistance and maintaining product integrity during storage and transport.

Additionally, PETG can be used in certain applications, offering improved clarity and enhanced chemical resistance, which is especially beneficial for products with high visual appeal requirements. Material selection is critical to achieving consistent performance, and the KPET 1200-208’s design accommodates these considerations effectively.

Applications and Market Potential

The wide-mouth preform is highly versatile. It is used in manufacturing containers for food products such as sauces, honey, and condiments, as well as industrial liquids and chemicals. The 70mm mouth facilitates easy filling, cleaning, and dispensing, making it ideal for high-volume operations that prioritize efficiency and hygiene.

From a market perspective, the KPET 1200-208 preform addresses the growing demand for large-capacity containers. Industries ranging from food processing to personal care benefit from its robust design and fast production rate. The combination of durability, high output, and material efficiency makes it a valuable asset for manufacturers looking to enhance productivity and reduce costs.
