Computerized Automatic Heel Seat lasting Machine TH-728A

The TH-728A Computerized Automatic Heel Seat Lasting Machine represents the latest advancement in footwear manufacturing technology, designed to enhance efficiency, precision, and quality in the heel seat lasting process. As shoe manufacturing evolves, automation and computerization have become essential to meet growing production demands and maintain superior craftsmanship. The TH-728A integrates cutting-edge computerized control systems with mechanical precision to automate the complex process of lasting heel seats, drastically reducing manual labor and error rates. Whether for high-end fashion footwear, sports shoes, or industrial boots, the TH-728A offers unparalleled reliability and performance, enabling manufacturers to scale production while maintaining consistent quality.

What is Heel Seat Lasting and Why Does It Matter?

Heel seat lasting is a critical phase in shoe production. It involves fixing the heel seat, the part of the shoe that supports the heel firmly onto the shoe’s last (the foot-shaped mold). The precision of this process directly affects shoe comfort, stability, and durability. Traditional heel lasting methods rely heavily on manual labor, which can lead to inconsistent results, higher defect rates, and longer production cycles. Automated heel seat lasting machines like the TH-728A minimize these issues by ensuring uniform pressure and alignment through computer-controlled operations.

Detailed Operational Description

Setup and Programming

Operators begin by selecting or programming the lasting cycle on the touchscreen interface. Parameters such as heel size, pressing force, pressing time, and clamp position can be input manually or recalled from pre-saved programs.

Loading the Shoe

The operator places the shoe, already assembled with the heel seat loosely attached, onto the shoe last fixture integrated within the machine. The shoe last ensures the shoe maintains its correct shape during the lasting process.

Automatic Clamping and Positioning

Once the start button is pressed, hydraulic clamps automatically engage to secure the shoe and heel seat firmly in place. The positioning arms move to align the heel seat perfectly with the shoe last, using sensors to confirm accuracy.

Lasting Process

The hydraulic press then applies consistent pressure on the heel seat, pressing it onto the shoe upper and sole. The computer controls the pressure precisely, ensuring the heel is securely attached without damaging delicate materials.

Unloading

After the programmed cycle completes, the clamps release, and the operator removes the finished shoe. The process is then ready to repeat for the next pair.
