Keye Technology's fully automatic bottle inspection equipment - precise solution for PET bottle defects

Packaging inspection equipment can comprehensively cover finished and semi-finished packaging products of different shapes and materials, with a core focus on precise detection of appearance defects in various types of packaging. Plastic packaging, with thermoplastic resin as its core raw material, can be processed into diverse packaging shapes through mature processes such as blow molding, injection molding, and extrusion. Common raw material types include PP, PE, PET, PS, PA, PC, ABS, PVC, etc.

Among them, PET has become the core production material for packaging products such as mineral water bottles and carbonated beverage bottles due to its excellent wear resistance and dimensional stability. However, during the production process, due to factors such as process parameters and raw material purity, PET bottles are prone to three typical defects:

1. Concavity/deformation of bottle body: The injection molding of the embryo tube at too high a temperature leads to uneven crystallinity of the embryo tube; the stretching ratio and inflation pressure parameters in the bottle blowing process are set unreasonably.

2. Bottle body bubbles: Insufficient drying of raw materials leads to residual moisture, which forms bubbles and silver streaks during processing, seriously affecting the appearance and structural strength of the product.

3. Black spots and impurities on the bottle body: Impurities from recycled materials are mixed in the raw materials, or dust on the extrusion and injection molding equipment is not cleaned up in time.

Addressing various flaw issues on PET bottle bodies, Keyi Technology's fully automatic bottle inspection equipment can efficiently handle them. Leveraging ultra-clear industrial cameras and deep learning AI algorithms, the equipment can precisely capture defects such as dents, deformations, black spots, and impurities, enabling online high-speed inspection and automatic removal of defective products. This helps enterprises enhance the quality of PET bottles upon leaving the factory, significantly reduce production losses, and rigorously maintain product quality standards.
