Italian Technology & Intelligent Efficiency

Italian Technology Core

Based on Italian technology, focusing on the middle and back side lasting. Ensures high-quality grouping while significantly saving manpower.

Auto Left & Right Foot Exchange

Features a unique auto exchange function, making the inner and outer waist upper lasting better and more compact, ideal for modern high-speed lines.

PLC Memory Function

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

Auto Cement System

Improves lasting quality and keeps the side wire unchanged while saving massive amounts of labor on the production line.

Redefining Heel and Side Lasting Quality

The GW-780EM is a state-of-the-art PLC Intelligent Glue Heel and Side Lasting Machine. Unlike front lasting machines that focus on the toe, this machine is engineered specifically to perfect the middle and back side of the shoe (the waist and heel). It is based on advanced Italian technology, which is renowned for precision and durability in footwear manufacturing.

In modern footwear production, saving manpower while increasing quality is the ultimate goal. The GW-780EM achieves this by integrating highly automated features such as the Auto Left and Right Foot Exchange, which ensures that the inner and outer waist areas are lasted seamlessly. The machine is highly suitable for a diverse range of shoes, including sports shoes, military shoes, football (skate) shoes, and ladies' flat shoes.

By utilizing a sophisticated PLC system, the machine can store up to 200 different shoe types. When switching production lines, operators simply recall the saved parameters, and the machine automatically adjusts its complex mechanical components. This reduces setup time from hours to minutes, making it an indispensable asset for modern, high-efficiency molding lines.

17 Special Skills for Precision Heel & Side Lasting

The GW-780EM is packed with 17 technical innovations, ensuring that every curve and contour of the heel and waist is perfectly lasted.

01 Infrared Glue Positioning

Glue location precise, adjust fast. Ensures the adhesive is applied exactly where needed.

02 Analog and True Tensioner

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

03 Last Back Highest Adjustment

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

04 Last Self-Balance Stock

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

05 Double Finger Force Flat Function

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

06 Low Temperature Hydraulic System

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

07 Circuit Integrated Modularization

Durable and easily maintain. Simplifies troubleshooting and repairs.

08 Extrusion Side Angle Leveling

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

09 Press Edge Double Balance Attach Last

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

10 Pincer Lasting Pull Rear Strap

Pincer pull the heel, the upper more compact.

11 Auto Cement Function

Improve lasting quality, unchanging side wire. Save labor.

12 Left & Right Foot Exchange Auto

Let the inner & outer waist upper better lasting and more compact.

13 Center Seat Automatically Moves

Optional function. Adjust the heel, waist joint is more natural, this function can help quickly replace the wiper.

14 PLC Auto Memory Function

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

15 Inner Waist Rubber Pen Auto Retraction

The inner waist automatically shrinks. The glue doesn't reach the upper, the glue position is accurate.

16 Waist, Heel Lasting High/Low Pressure

Use two stage press, can make lasting better.

17 Press Cylinder Directional Precise Control

Double hydraulic cylinder, ensure suitable speed and pressure.

Frequently Asked Questions

1. What is the main difference between a toe lasting machine and a heel/side lasting machine?

A toe lasting machine shapes the front of the shoe upper over the toe of the last. The GW-780EM, however, focuses entirely on the middle and back side of the shoe (the waist and heel). It shapes the heel counter and side contours, ensuring the back part of the shoe is perfectly molded.

2. How does the PLC Auto Memory function work?

The PLC system allows you to store the specific mechanical settings for up to 200 different shoe types. When you switch to a new style on the production line, you simply recall the saved data, and the machine automatically adjusts its parameters. This drastically reduces setup time and improves consistency.

3. What is the benefit of the Auto Left & Right Foot Exchange?

Shoes are not perfectly symmetrical, and the inner and outer waist areas require different handling. This function automatically adjusts the machine to handle both left and right shoes seamlessly, ensuring that the lasting on the inner and outer waist is uniform and compact.

4. How does the machine prevent damage to delicate shoe uppers?

It features the "Extrusion Side Angle Leveling" function to avoid double eyelid quality 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 the material.

5. What type of hydraulic system does it use?

It utilizes a low-temperature hydraulic system. By keeping the oil temperature at approximately 50°C, the machine ensures stable operation and significantly extends the lifespan of the hydraulic components.

6. Is the glue application automatic?

Yes, the machine features an Auto Cement Function with Infrared Glue Positioning. This ensures precise glue location, prevents glue from reaching unwanted areas (like the inner waist), and saves massive amounts of labor.
