Main features

• Integrated PLC control system with multi-language interface enables easy operation and flexible product switching
• Built-in data storage function allows quick recall of thousands of product parameters for efficient production management
• Thermal transfer printing system enables real-time coding directly on packaging film, reducing labeling costs
• Adjustable bag forming system supports flexible control of bag length and width for different packaging needs
• Double-channel operation allows simultaneous weighing and feeding to improve packaging efficiency and stability

Working principle

The machine uses a multi-channel feeding system to evenly distribute materials into the weighing units. Sensors and weighing modules accurately measure or count the products based on preset parameters. Once the required weight or quantity is reached, the material is discharged into a bag formed by PE film. The system then completes sealing and cutting automatically. A PLC control system manages the entire process, while the printing unit marks product information directly onto the packaging.

Application scenarios

• Plastic parts packaging such as connectors, clips, and molded components
• Electronic accessories packaging including small modules and device components
• Magnetic retainer and motor component packaging applications
• Hardware and light industrial parts packaging requiring high precision
• Small component packaging for assembly lines and manufacturing plants
• Fastener and mixed small parts packaging in industrial production
• Precision parts packaging requiring traceability and consistent quality control
