In today’s footwear manufacturing industry, efficiency, precision, and versatility are paramount. The Shibang-2530D / 2533D / 2534D lasting machines series stands at the forefront of technological innovation, designed to meet these very demands. Engineered to provide exceptional performance across a broad spectrum of shoe types and production scales, this series incorporates advanced mechanical and electronic systems, delivering outstanding lasting quality while optimizing operational efficiency and cost-effectiveness. This series builds upon the core strengths of traditional lasting machines but introduces cutting-edge features such as multi-axis servo-controlled adhesive application, innovative glue management technology, and full digital intelligence integration. These improvements are specifically aimed at overcoming the common challenges faced in the lasting process, including adhesive waste, time-consuming shoe type changeovers, labor intensity, and production consistency.

Innovative Adhesive System without Glue Tray

One of the hallmark features of the Shibang-2530D / 2533D / 2534D series is its revolutionary no-glue tray adhesive system. Unlike conventional lasting machines that rely on glue trays for adhesive feeding, which often result in frequent glue replacement, overflow, spillage, and cleaning downtime, the Shibang series employs a sophisticated multi-axis servo adhesive pen feeding method.

This system precisely controls the application of glue via a servo-driven adhesive pen that follows a preprogrammed, highly accurate trajectory on the shoe sole and upper. By eliminating the glue tray, the machine effectively:

• Reduces glue overflow and dripping: This prevents adhesive waste and contamination, maintaining a cleaner work environment and saving adhesive costs.

• Improves bonding quality: The controlled application ensures consistent glue thickness and placement, leading to stronger and neater adhesion, particularly important for challenging shoe designs such as pointed-toe women’s shoes and soft or thin midsoles.

• Simplifies maintenance: Without glue trays, the machine requires less frequent cleaning and glue replacement, reducing downtime and labor requirements.

This system embodies a significant technological advancement that not only enhances the lasting quality but also streamlines the entire production workflow, empowering manufacturers to operate at peak efficiency.

Servo-Controlled Adhesive Feeding for Precision and Efficiency

The adhesive feeding system on the Shibang series is driven by advanced five-axis servo motors, which provide exceptional control and flexibility. The servo system enables the adhesive pen to follow a precisely mapped path, adapting to the contours and specific adhesive needs of various shoe models.

Key benefits of this servo-driven adhesive feeding include:

• Perfect lasting effect on diverse shoe types: Whether handling the narrow, angular profiles of pointed-toe women’s shoes or the soft, delicate structure of midsoles, the servo adhesive system ensures uniform and adequate glue coverage without excess.

• Minimized adhesive waste: The precision trajectory reduces overflow and dripping common with traditional glue plates, decreasing material waste and associated costs.

• Faster changeover between shoe models: The servo system’s flexibility allows rapid reprogramming and adjustment for different shoe shapes and sizes without mechanical modifications.

• Enhanced durability of bonding: The consistent adhesive application strengthens the bond between shoe components, reducing defects and improving product longevity.

This combination of precision and adaptability makes the Shibang series a versatile solution that supports a wide range of footwear production needs with minimal manual intervention.

Time-Saving Design for Increased Production Efficiency

Production speed and uptime are crucial metrics for any manufacturing facility. The Shibang-2530D / 2533D / 2534D series features a design specifically aimed at maximizing uptime and throughput.

• No glue tray design for fast changeover: By eliminating glue trays, the machine bypasses the usual glue tray replacement and cleaning processes required when switching shoe types, substantially reducing setup times.

• Digital memory of shoe types: The machine can store detailed settings for multiple shoe models, including adhesive path, pressure settings, and timing sequences. This allows operators to switch models by simply selecting the shoe type from the interface, further accelerating changeover.

• User-friendly touch control panel: A modern touchscreen interface provides quick access to machine settings, status, and troubleshooting, making operations smoother and reducing operator errors.

• High production capacity: The machines are engineered for continuous operation, capable of producing up to approximately 1400 pairs per 8-hour shift, depending on the model and shoe complexity.

By minimizing changeover delays and optimizing continuous running, the Shibang series helps factories boost overall productivity without compromising quality.

Labor-Saving Features Reducing Operational Costs

Footwear lasting traditionally requires skilled labor and often involves repetitive, labor-intensive processes. The Shibang-2530D / 2533D / 2534D series alleviates these challenges through intelligent automation and ergonomic design:

• Automated adhesive application: The servo-driven pen applies glue precisely without manual intervention, reducing reliance on skilled workers for consistent adhesive placement.

• Reduced cleaning labor: Since there is no glue tray and overflow is minimized, operators spend less time cleaning glue residues, allowing staff to focus on higher-value tasks.

• Simplified operator training: The machine’s intuitive interface and memory functions reduce the skill barrier for operators, speeding up onboarding and enabling a more flexible workforce deployment.

• Ergonomic machine layout: Controls and operational components are positioned for ease of use, minimizing operator fatigue and improving shift productivity.

Together, these features contribute to significant labor cost savings while maintaining high quality in the lasting process.

Cost-Effective Operation through Material and Energy Efficiency

The Shibang lasting machines are designed to deliver long-term cost advantages for manufacturers by optimizing resource use and maintenance:
