Why Is Automatic Gluing the Best Choice for Ensuring Glue Does Not Come Off After Molding?

Introduction to the TH-777MA 9 Pincers Computer Memory Control Automatic Servo Cementing Toe Lasting Machine

In the evolving footwear manufacturing industry, ensuring high product quality and operational efficiency is vital. Guangdong Tenghong Machinery Technology Co., LTD., a leading manufacturer located in Dongguan, China, has developed the TH-777MA 9 Pincers Computer Memory Control Automatic Servo Cementing Toe Lasting Machine—a state-of-the-art solution that provides unmatched precision and reliability in the shoe lasting process. This advanced machine specializes in automatic gluing during toe lasting, which plays a critical role in enhancing the glue’s adherence and preventing it from coming off after molding.

The TH-777MA uses a fully oil pressure operation system, offering excellent stability and consistency throughout production. Equipped with a PLC system featuring a graphic display touch screen, operators can manage settings intuitively, set key parameters like stroke and time precisely, and secure configurations through key switches to prevent unauthorized modifications. Its powerful computer memory can store up to 500 groups of shoe lasting parameters, facilitating rapid adaptation to different shoe designs.

With 9 pincers and intelligent servo control, the TH-777MA balances tension on the vamp and controls the glue application process with exceptional precision. Its adjustable inner support table and multi-stage pressure settings ensure optimal lasting effects and a highly durable glue bond. Producing as many as 1,440 pairs in 8 hours, with generous oil capacity and strong power inputs, this automatic servo cementing toe lasting machine stands at the forefront of manufacturing high-quality footwear efficiently.

Key Features of the TH-777MA Automatic Servo Cementing Toe Lasting Machine

The cornerstone of the TH-777MA is its fully oil pressure-operated system, which grants the machine stability and precision superior to many mechanical or pneumatic counterparts. This oil pressure operation minimizes vibrations and maintains smooth force during glue pressing, essential for ensuring that glue bonds firmly and does not peel after molding. This consistent pressure directly translates to shoe durability and customer satisfaction.

The machine’s PLC controller with a touchscreen interface revolutionizes user interaction. Operators can input parameters such as stroke lengths and timing digitally and lock these values with key switches, preventing accidental or unauthorized changes. This control ensures production consistency—a critical advantage for manufacturers looking to maintain fixed quality standards across batches.

Its computer memory capability, storing up to 500 parameter sets, allows rapid switching between different shoe lasts and styles, creating significant savings on setup times and reducing production downtime. The electric control of the claw plate adjustment, featuring double-point quick adjustment and lateral movement, further boosts flexibility and accuracy in clamping the vamp for precise glue application.

The unique design of the middle pincer, capable of 15-degree deflections shown on the touch screen, and the fifth pincer’s automatic rotation for inner waist lasting, establishes optimal tension distribution. This balance prevents glue separation caused by uneven stretching or material distortion.

Adjustable strokes on the pincers—both automatic pull-down and manual lifting—allow fine-tuning of vamp tension to achieve the best lasting position. This precise control is crucial in ensuring the glue’s adhesive properties are fully realized, avoiding weak bonding points which can lead to glue coming off post-molding.

The glue tray’s two-stage structure supports rapid width adjustment and automatic changes between left and right feet, achieving the best sticking point and uniform glue coverage around the toe area. This intelligent glue management reduces material waste while maintaining consistent product quality.

Notably, the press head mechanism’s two-stage adjustable pressure enables constant or positioning control during the initial pressure phase, providing strong adhesion without damaging delicate uppers or glue layers, which further ensures glue durability after molding.

Additional features such as the electrically adjustable large seat sweep knife for descending position and double-speed forward motion of the wiper mechanism contribute to the machine’s capacity to maintain high production rhythms while ensuring precise glue application and lasting.

Manufacturing Excellence and Production Advantages

Guangdong Tenghong’s TH-777MA is crafted with high-quality materials and undergoes strict quality inspections following the ISO9001:2008 standard, ensuring durability and reliability even in demanding footwear production environments.

Its oil pressure hydraulic system provides consistent, smooth force application throughout operations, preventing glue peeling caused by uneven pressure or vibration. This stability significantly reduces defects, waste, and the need for rework, directly impacting production costs and profitability.

The PLC system’s integrated error diagnostic feature helps quickly identify and troubleshoot issues, minimizing downtime and maintaining production continuity. This practical innovation reduces the total cost of ownership and boosts line efficiency.

The machine’s large capacity oil filling (136 liters) and robust 3 HP motor ensure it can handle heavy-duty operations without performance degradation. This endurance means factories can rely on continuous, high-volume production with minimal maintenance interruptions.

The adjustable inner support table and multi-level pressure relief function on the second rise of the inner platform protect against last slippage, improving adhesive pressure consistency. Such features reduce mechanical strain on both glue and material, increasing the finished shoe’s quality and increasing factory throughput.

Guangdong Tenghong’s continued development of specialized automation—including auxiliary sweep knife mechanisms, blank holding components, and toe cross-light structures—supports operator precision and ease of monitoring, facilitating lean, high-precision manufacturing practices.

Production-wise, the machine supports a fast pace with productivity reaching 1,440 pairs in an 8-hour shift, offering excellent return on investment while maintaining consistently high glue adhesion quality. These features meet the rigorous demands placed on modern shoe manufacturers focusing on fast turnaround without quality compromise.

The company’s dedicated professional teams provide comprehensive pre-sale consultation, installation, and ongoing maintenance services, guaranteeing optimized plant planning and after-sales support for enhanced lifecycle performance.
