As a product manager at Guangdong Tenghong Machinery Technology Co., LTD., I am excited to introduce the TH-727DP Hydraulic Automatic Heel Seat Lasting Machine, a reliable and innovative solution designed to elevate the quality and efficiency of shoe manufacturing. Guangdong Tenghong, established in 2000 and located in Dongguan City—one of China's famed shoe manufacturing hubs—is widely recognized for producing high-quality machinery dedicated to the footwear, handbag, and leather goods industries.

The TH-727DP is engineered specifically for lasting shoes with heel heights less than 80mm and soft midsoles. Combining advanced hydraulic pressure with precise adjustments, this machine automates the heel seat lasting process to ensure consistent and perfect shoe shapes. Equipped with carefully designed control systems and adjustment indicators, the TH-727DP simplifies operations for manufacturers while delivering outstanding adhesion and finish. Its capability to work with a wide range of shoe types, including stitch-down models, makes it a versatile choice for manufacturers seeking to optimize quality, reduce labor costs, and increase throughput. This machine represents the strength of Chinese manufacturing: delivering advanced technology at a competitive price without compromising on quality.

Product Features of the TH-727DP Hydraulic Automatic Heel Seat Lasting Machine

The TH-727DP Hydraulic Automatic Heel Seat Lasting Machine incorporates numerous features that set it apart as a premium piece of manufacturing equipment, supporting shoe producers in delivering perfect lasting results with automated gluing technology:

Hydraulic System with Precise Pressure Control: 

The hydraulic pressure system operates at 40kg/cm², providing consistent and adjustable force across the heel seat lasting process. This ensures firm adherence of the sole and upper, reducing defects caused by insufficient or uneven pressure. The precision hydraulic meters allow real-time monitoring and fine-tuning to meet different shoe specifications.

Innovative Adjustable Indicators for Accurate Positioning: 

The machine is equipped with indication scales both for adjusting the last’s height and setting its forward position. These scales allow operators to quickly and precisely set the last, optimizing the shoe shape and avoiding lasting errors. The auxiliary supporter adjusts rapidly through gears, gear racks, and ratchets, maximizing workflow efficiency.

Wiper Device for Enhanced Lasting Quality: 

The secondary pressing of the last supporter features an integrated wiper device to smooth the lasting surface uniformly. This mechanism increases the adhesion between upper and sole while upgrading the overall finish quality, essential for premium shoes sold in competitive markets.

Wide Range of Wipers and Forming Bands: 

The TH-727DP comes with various wipers and forming bands wrapped by chains to accommodate the shapes of many shoe models. This versatility reduces changeover time, helping production lines adapt quickly to new designs or customer demands.

Capability for Stitch-Down Shoes: 

Equipped with components that support stitch-down shoe production, the machine serves manufacturers who focus on durable, high-quality footwear styles that require strong, reinforced lasting methods.

Robust Build with Efficient Power Use: 

Powered by a 2HP motor and 0.32 kW heating power, the machine balances energy efficiency with industrial-grade performance. The compact footprint (1030x720x1450mm) and 431kg net weight provide stability during continuous operation.

High Productivity for Large-Scale Manufacturing: 

With a rate of approximately 3000 pairs per hour, the TH-727DP offers an excellent blend of speed and quality. This level of throughput supports manufacturers aiming to meet high-volume orders without compromising on precision or finish.

User-Friendly Adjustable Handles: 

All pressure and positioning adjustments are centralized on the front panel, allowing quick setup changes and reducing operator training needs. This also means fewer errors and increased confidence in production results.

These features establish the TH-727DP as an industry-leading shoe lasting machine designed for manufacturers committed to high-quality production with efficient operations.

Manufacturing Advantages and Process Benefits

Investing in the TH-727DP Hydraulic Automatic Heel Seat Lasting Machine offers shoe manufacturers numerous production advantages through its advanced design and automated functionality:

Consistent Perfect Shape and Adhesion: 

The precise hydraulic pressure and adjustable indicators ensure every shoe maintains a uniform heel shape and strong bonding between sole and upper. This consistency is vital for building brand reputation by delivering products with superior fit, durability, and aesthetic appeal.

Reduced Labor and Error: 

Automation of key processes, including pressing and smoothing with the wiper device, reduces manual intervention. This minimizes human error, lowers labor costs, and increases factory throughput, enabling manufacturers to achieve better economies of scale.

Flexibility Across Shoe Models: 

The machine supports different shoe styles including casual, sports, and stitch-down shoes with soft midsoles, making it adaptable to customer needs and changing fashion trends. The variety of wipers and bands ensures seamless transitioning between models, reducing downtime.

Enhanced Material Utilization: 

The even pressure application prevents excessive glue wastage and improper adhesion, leading to savings on materials and reducing costly warranty returns or end-product rejections.

Durable and Easy to Maintain: 

The machine’s sturdy construction and use of standardized parts simplify routine maintenance and ensure long-term reliability. This durability aligns with the demands of high-volume manufacturing environments characteristic of China’s shoe industry.

Energy and Cost Efficiency: 

Using a moderate 2HP motor with smart hydraulic design, the TH-727DP balances performance and operational costs, making it appealing for manufacturing plants focusing on cost-effective production with high quality.
