Four Core Advantages for Universal Application

Direct Substitute for Hand-Pull Process

Specially developed to replace the traditional manual hand-pulled waist process. Delivers consistent, machine-controlled pressure that human hands cannot match.

Suitable for All Kinds of Shoes

Highly adaptable and versatile. Whether you are producing sports shoes, leather shoes, or casual footwear, this machine delivers exceptional lasting quality.

Designed for Mass Production

A practical machine developed specifically for mass production lines. It offers high cost-effectiveness and stable performance to keep your line moving.

PLC Auto Memory Function

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

The Ultimate Universal Workhorse for Heel and Waist

The GW-780 is a quintessential intelligent heel and side lasting machine. It is designed as a highly practical, cost-effective solution for mass production lines that are looking to upgrade their manufacturing process by eliminating the manual hand-pull waist operation.

In traditional shoe factories, shaping the heel and waist (the middle and back of the shoe) was a labor-intensive task requiring skilled workers to physically pull and glue the upper. The GW-780 completely revolutionizes this by using automated mechanical pressure, pneumatic controls, and hydraulic systems to achieve a tighter, more uniform fit than manual labor ever could.

What makes the GW-780 truly stand out is its universal applicability. Unlike specialized machines tailored for a single shoe category, the GW-780 is highly adaptable and suitable for all kinds of shoes. From sports shoes and military boots to delicate ladies' footwear, it delivers consistent, high-quality results. Combined with the PLC Auto Memory Function (capable of storing 200 shoe types), switching between different products is faster and more reliable than ever.

12 Special Skills for Precision and Stability

The GW-780 is equipped with 12 core technical features, ensuring that every curve of the heel and waist is perfectly lasted without manual intervention.

01 Analog and True Tensioner

Wide range adaption, last data, attached toe band research by computer simulation.

02 Last Back Highest Adjustment

Wide range of last high adjustment. Children's shoes can be used to high tops.

03 Last Self-Balance Stock

Auto balance according to the last shape, better for lasting flat.

04 Double Finger Force Flat Function

Press enough pressure to the upper, let the lasting more flat.

05 Low Temperature Hydraulic System

Oil temperature keep about 50°C. Ensure stable and improve usage life.

06 Circuit Integrated Modularization

Durable and easily maintain. Simplifies troubleshooting and repairs.

07 PLC Auto Memory Function

Can store 200 kinds of shoe type. Adjust auto use, reduce adjustment time.

08 Press Edge Double Balance Attach Last

Dual interactive balance structure, the largest surface is fitted last type, improve lasting quality.

09 Pincer Lasting Pull Rear Strap

Pincer pull the heel, the upper more compact.

10 Extrusion Side Angle Leveling

Avoid heel knot double eyelid quality problems. Improve lasting quality.

11 Waist, Heel Lasting High/Low Pressure

Use two stage press, can make lasting better.

12 Press Cylinder Directional Precise Control

Double hydraulic cylinder, ensure suitable speed and pressure.

Frequently Asked Questions

1. How does the GW-780 replace the manual hand-pull process?

Instead of relying on an operator's physical strength to pull and glue the upper to the waist, the GW-780 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 the GW-780 suitable for all shoe types?

Yes, it is designed as a universally applicable machine. It is highly suitable for mass production of all kinds of shoes, including sports shoes, leather shoes, and casual footwear, delivering exceptional lasting quality across different materials.

3. How many shoe types can the machine remember?

The PLC Auto Memory Function can store up to 200 kinds of shoe types. When you switch production to a new style, simply recall the saved parameters to drastically reduce setup time and ensure consistent results.

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

It features several protective technologies, including "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.
