Four Core Advantages for Replacing Manual Labor

Directly Replace Hand-Pulled Process

Specially developed to replace the traditional manual hand-pulled waist process. Delivers consistent, machine-controlled pressure that humans cannot match, significantly reducing labor costs.

Left & Right Foot Auto Exchange

Features a unique auto exchange function, making the inner and outer waist upper lasting better and more compact. Essential for high-efficiency production lines.

Ideal for Frequent Style Changes

Use for usually change shoe type production line. The intelligent memory system makes switching between different shoe sizes and styles incredibly fast and easy.

PLC Auto Memory Function

Can store up to 200 kinds of shoe types. Auto recall settings to minimize adjustment time and eliminate operator guesswork.

Revolutionizing the Waist Lasting Process

In traditional shoemaking, the waist and heel area is often shaped using a "hand-pulled" process, where a skilled operator physically stretches and glues the upper to the last. This method is highly dependent on operator skill, physically exhausting, and inconsistent. The GW-780E Intelligent Memory Heel and Side Lasting Machine is a revolutionary solution designed specifically to directly replace this hand-pulled process.

By utilizing advanced mechanical pressure and intelligent controls, the GW-780E shapes the middle and back of the shoe with a level of precision and consistency that manual labor cannot achieve. It is highly suitable for sports shoes and ladies' leather shoes, providing a smooth, wrinkle-free finish every time.

What truly sets the GW-780E apart is its suitability for production lines that frequently change shoe types. Thanks to the PLC Auto Memory Function and the Auto Left/Right Foot Exchange, switching from one size or style to another is seamless. The machine remembers the exact settings for up to 200 shoe types, so your operators can focus on production, not on complex machine adjustments. It is the ultimate tool for modern, agile footwear manufacturing.

Frequently Asked Questions

1. How does the GW-780E replace the hand-pulled waist process?

Instead of relying on an operator's physical strength to pull and glue the upper to the waist, the GW-780E uses precise hydraulic pressure, dual finger force flat functions, and pincer lasting to mechanically shape the upper. This ensures a tighter, more consistent fit while eliminating the need for expensive manual labor.

2. Is this machine suitable for a factory that changes styles frequently?

Absolutely. It was specifically designed for production lines that usually change shoe types. The PLC Auto Memory function stores the settings for up to 200 shoe types, allowing operators to switch styles in seconds without complex manual adjustments.

3. What does the "Left & Right Foot Auto Exchange" do?

Shoes are not perfectly symmetrical, requiring different handling for the inner and outer waist. This function automatically adjusts the machine's mechanical action to fit both left and right shoes seamlessly, ensuring that the lasting is uniform and compact on both sides.

4. How does the machine prevent damage to delicate leather?

It features several protective technologies, including the "Extrusion Side Angle Leveling" to avoid double eyelid problems at the heel, and the "Press Edge Double Balance Attach Last" mechanism. Combined with the two-stage High/Low pressure control, it ensures a snug fit without crushing or marking the material.

5. What type of hydraulic system is used?

The machine utilizes a low-temperature hydraulic system that keeps the oil temperature at approximately 50°C. This ensures highly stable operation, prevents overheating, and significantly extends the lifespan of the hydraulic components.
