TH-710A Heavy-duty Walled Sole Attaching Machine: Built for Strength and Precision in Shoe Manufacturing

The TH-710A Heavy-duty Walled Sole Attaching Machine is designed for one of the most demanding steps in the shoemaking process—attaching soles to walled upper structures. Whether it’s high-top sneakers, heavy-duty boots, or safety footwear, this machine delivers strength, precision, and repeatability. Manufactured by Jiangsu Tonghua Intelligent Shoe Machinery Co Ltd, it is built to meet the rigorous demands of industrial footwear production.This review explores the TH-710A in depth, covering its mechanical design, performance efficiency, material compatibility, and industrial applications.

 Product Overview

Sole attaching is a key process in ensuring a shoe’s durability, comfort, and structural integrity. The TH-710A is specially designed for footwear with walled constructions—where the sole wraps up along the sidewalls of the upper. These styles are common in athletic shoes, safety boots, and many casual shoe designs.The machine uses high-pressure hydraulics and a precisely aligned pressing system to deliver uniform force across the upper and sole joint, ensuring consistent bonding and long-lasting wear performance. Built with durability and operator comfort in mind, the TH-710A is an excellent fit for mass production environments where quality cannot be compromised.

Construction and Design

The TH-710A boasts a heavy-duty cast steel body that reduces vibration and maintains pressing alignment over time. Its core pressing mechanism is powered by a hybrid hydraulic-pneumatic system that ensures both power and control. This means strong, consistent pressing force without over-compressing the materials.The pressing plate conforms to the curved structure of the shoe wall, giving even pressure around the entire sole border. Additionally, safety features such as emergency stop switches and two-hand control are integrated to protect the operator.

Performance and Operation

The TH-710A is engineered for high-volume production. Its average cycle time of 12 to 18 seconds per shoe allows for efficient throughput, especially when paired with other automated assembly equipment.It excels in applications where force distribution and material bonding strength are critical. Whether attaching a rubber sole to a leather upper or a PU sole to a mesh and synthetic hybrid, the machine maintains even pressure to prevent weak points or air pockets.Ease of use is another major benefit. Operators can adjust pressure, timing, and positioning with straightforward manual controls, which reduces training time and machine downtime.

Applications

The TH-710A is suitable for manufacturers producing:

• Walled sneakers with molded rubber or EVA soles

• Military or tactical boots

• Safety shoes with steel or composite toe caps

• Hiking or outdoor footwear requiring waterproof sole bonds

• Fashion-forward sneakers with wrapped midsole designs

Advantages

• High pressure output ensures secure bonding of various sole materials

• Consistent pressing eliminates common issues like unbonded edges or sole warping

• Durable steel structure handles repetitive industrial use

• Operator-friendly controls enable quick adjustment and low learning curve

• Wide material compatibility covers rubber, EVA, PU, and more

 Limitations

• Requires a dedicated space due to size and weight

• Semi-automatic operation requires trained personnel for setup and use

• Best suited for walled soles only; not ideal for flat sole attachment processes

• Regular maintenance needed for hydraulic system components.
  
  

The TH-710A Heavy-duty Walled Sole Attaching Machine is a high-performance solution designed for durability-focused footwear. Its precision, pressure control, and robust build make it ideal for applications where secure sole bonding is essential. While it requires a committed operator and scheduled maintenance, the return on investment is clear for factories that value consistency, strength, and speed in their sole assembly process.
