In the modern catering industry, takeaway paper soup cups are an important representative of disposable tableware. The stability and sealing of their bottom structure are directly related to the sanitation and safety of food, the use experience of consumers, and the brand image of merchants. All of this is inseparable from the precise cutting and forming process of the die device in the forming machine.

The bottom structure of the takeaway paper soup cup starts with the selection of high-quality raw materials. The use of food-grade wood pulp paper as the base material not only ensures the safety and harmlessness of the product, but also gives it good flexibility and plasticity. On this basis, a layer of food-grade PE film is covered on the surface of the paper through the laminating process, which further enhances the waterproof performance and durability of the paper. The existence of this layer of film not only protects the paper from liquid erosion, but also provides necessary support for subsequent cutting and forming processes.

The die device is the core component of the forming machine, and its design is directly related to the shape, size and stability of the bottom structure of the soup cup. In the design process, the physical properties of the paper, cutting efficiency, bearing capacity of the bottom structure and sealing requirements need to be comprehensively considered.
Shape design: The shape of the bottom structure of the soup cup is varied, and the common ones are flat bottom, round bottom, wavy bottom, etc. Each shape has its own unique application scenarios and advantages. For example, the flat bottom structure is stable and suitable for placement; the round bottom is more beautiful and easy to hold; the wavy bottom can increase the strength of the bottom structure to a certain extent, while giving the product a unique visual effect. Designers need to carefully select or design the bottom shape according to actual needs.
Size determination: The size of the bottom structure must match the cup body to ensure the coordination and stability of the overall structure. At the same time, the ratio of the bottom diameter to the height must also be considered to optimize the load-bearing capacity and sealing. The size design must be calculated and experimentally verified many times to ensure the practicality and aesthetics of the final product.
Material selection: The material of the die device must have high strength, wear resistance, corrosion resistance and other characteristics. Common materials include high-speed steel, cemented carbide, etc. These materials not only ensure the durability of the die, but also improve cutting efficiency and quality.

Cutting and forming are the core links in the bottom punching process, and their quality is directly related to the stability and sealing of the bottom structure of the soup cup.
Cutting depth control: Cutting depth is a key parameter in the cutting process. Too deep a cut will cause the paper to break and affect the stability of the bottom structure; too shallow a cut may cause the bottom structure to be incomplete and affect the sealing. Therefore, during the cutting process, the cutting depth must be strictly controlled to ensure that the cutting line is clear, complete and of moderate depth.
Molding accuracy control: Molding accuracy is an important indicator for measuring the quality of the bottom structure of the soup cup. During the molding process, it is necessary to ensure that the bottom structure has an accurate shape, consistent size and smooth edges. This requires the die device to have high precision, high rigidity and high stability to cope with various challenges in high-speed cutting and molding processes.
Process optimization: In order to improve the efficiency and quality of cutting and molding, the process must also be optimized. For example, use advanced cutting technology and molding processes such as laser cutting and ultrasonic welding; optimize the cutting path and molding sequence to reduce material waste and processing time; strengthen equipment maintenance and maintenance to ensure that the equipment is always in the best working condition.

During the bottom punching process, quality control is the key to ensuring product quality and stability.
Online detection: During the cutting and molding process, online detection equipment must be used to monitor the bottom structure in real time. By testing key parameters such as cutting depth, shape, and size, potential problems can be discovered and corrected in a timely manner to ensure that product quality meets design requirements.
Sampling inspection: Sampling inspection of finished products is an important means to ensure product quality. By testing key performance indicators such as the stability, sealing, and load-bearing capacity of the bottom structure, the product quality level can be comprehensively evaluated. For unqualified products, the causes must be traced back in a timely manner and corrective measures must be taken.
Continuous improvement: In the process of quality control, continuous improvement should also be emphasized. By collecting and analyzing product quality data, potential problems and improvement points can be discovered; in combination with customer needs and market trends, product design, processes, and quality control processes are continuously optimized; employee training and technical exchanges are strengthened to improve the overall quality and innovation capabilities of the team.
