Product Overview
The Haofeng SE-73F flip-mold cup machine (also commonly referred to as a flip-mold cup-making machine) is a fully automatic flip-mold plastic thermoforming device independently developed by Haofeng (Tianjin) Intelligent Manufacturing. It features three core characteristics—high-speed operation, overall machine stability, and high-precision molding—and is specifically designed for the large-scale mass production of disposable plastic packaging containers.
Unlike traditional fixed-table cup-making machines, this model incorporates the industry-proven conjugate cam flip mechanism combined with curved guide rail mold opening and closing technology. Through a 75° mold table flipping forming process, it optimizes the stress distribution of the sheet material at its source, thoroughly addressing common industry pain points such as overly thick cup bottoms, uneven wall thicknesses, and blurred edges found in conventional cup-making machines. This results in products with uniform wall thickness, well-defined contours, and consistent appearance. The entire process integrates servo sheet feeding, zone-controlled constant-temperature heating, positive-pressure flip-mold forming, integrated punching and cutting, and automatic stacking and discharge, offering a high degree of automation and strong production stability. It is the preferred choice for high-quality, high-efficiency mass production of disposable cups, bowls, and boxes.
Core Forming Principle
The SE-73F flip-mold cup machine employs an original conjugate cam flip mechanism paired with a curved guide rail mold opening and closing system, complemented by a servo-driven positive-pressure stretching forming system. Its core operating logic differs from that of ordinary vertical-opening-and-closing mold equipment:
The machine’s lower mold table can perform a rapid approximately 75° flipping motion, working in tandem with precise servo-assisted positive-pressure stretching. This ensures more uniform stress distribution, more thorough stretching, and smoother material flow during the forming process. It effectively resolves quality defects inherent in traditional forming processes—such as excessive material buildup at the cup bottom, insufficient wall stretching, significant wall-thickness variations, product deformation, and unclear edges—resulting in container products with three-dimensional, full-bodied edges, consistent wall thickness throughout, and uniform structural strength, thereby significantly improving yield rates and product aesthetics.
Machine Structure and Fully Automated Workflow
The equipment adopts an integrated design, eliminating the need for separate component assembly. From sheet input to finished-product output, it operates in a fully automated closed-loop process, ensuring smooth workflow transitions, low failure rates, and suitability for long-term continuous mass production.
1. High-Precision Servo Sheet-Feeding System
Utilizing a servo motor chain-drive configuration coupled with a dedicated automatic tensioning track structure, this system effectively prevents issues like sheet drooping, deviation, or uneven tension during long-distance feeding. With rapid response and high feeding accuracy, the system maintains stable, jam-free sheet delivery throughout the process, laying the groundwork for subsequent uniform heating and precise forming, thus reducing raw-material waste and forming defects.
2. Tunnel-Type Zone-Controlled Heating System
Equipped with a tunnel-type radiant heating furnace featuring imported heating tile core components, the upper and lower heating tunnels enable independent temperature control for each zone. With fast heating response and excellent internal temperature uniformity, this system accommodates the softening and forming needs of various materials and sheet thicknesses, preventing localized overheating or insufficient heating that could lead to poor forming outcomes, and ensuring consistent thermal conditions across every batch of sheets.
3. High-Speed Flip-Mold Table Forming System (Core Structure)
The mold table is driven by a servo motor paired with a hardened gear reducer, relying on the precise control of the conjugate cam to regulate flipping angles and opening/closing rhythms, while curve-guided rails provide accurate positioning limits. The entire machine operates at high speed and stability, with a maximum production rate of up to 30 molds per minute. Flipping motions are smooth, positioning is precise, and there is no shaking or deviation; even after prolonged continuous operation, the machine remains deformation-free and true to its intended path, making it ideal for factory environments requiring 24-hour uninterrupted mass production.
4. Positive-Pressure Forming + Integrated Punching and Cutting System
Equipped with a dual-screw balanced pressure-forming mechanism, the depth of forming can be freely adjusted to suit the production of cups, bowls, and boxes of varying depths. Utilizing an integrated synchronous punching and cutting process between the upper and lower die blades, the system delivers balanced cutting force and precise positioning, producing clean, burr-free cuts with low cup-separation rates, eliminating the need for manual secondary edge-trimming and greatly simplifying downstream processes while boosting production efficiency.
5. V-Shaped Robotic Arm Automatic Stacking System
At the end of the line, a specialized V-shaped robotic arm equipped with suction-cup stacking mechanisms automatically completes the tasks of tidying and organizing finished products, accurately counting them, and continuously stacking them for discharge. The stacking is neat, without misaligned cups or material jams, ready to connect directly to downstream packaging operations, realizing fully unmanned automated production and significantly reducing labor costs.
Core Performance and Product Advantages
1. Flip-Molding Process Ensures Extremely Uniform Wall Thickness
Leveraging the 75° mold table flipping forming technology and optimizing the sheet-stretching stress logic, this machine completely eliminates common issues such as thick cup bottoms, thin walls, and vague edges. The resulting products feature consistent wall thickness throughout, full, well-defined edges, and uniform structural strength, delivering a finished-product appearance far superior to that of traditional cup-making equipment.
2. High-Speed, Stable Mass Production with Efficient Capacity
With its precision-conjugate cam and curve-guided rail transmission structure, the machine operates smoothly and precisely, reaching speeds of up to 30 molds per minute. High-speed operation is free from shaking or deviation, supporting long-term continuous mass production with stable capacity and low failure rates.
3. High Forming Accuracy and Steady Yield Rates
