The TH-517AB Hot Air Steam Ironing Wrinkle Removal Machine is a state-of-the-art industrial tool designed specifically for efficiently hammering and removing wrinkles from leather uppers used in shoe manufacturing. It is equally effective for both men’s and women’s footwear, providing a smooth, flawless finish that enhances the look, fit, and feel of leather uppers. This machine integrates advanced steam and hot air technologies with mechanical hammering and ironing actions, offering a comprehensive solution for leather upper wrinkle removal that preserves the leather’s integrity while improving its surface quality.

Versatile Hammering and Wrinkle Removal for Leather Uppers

One of the primary advantages of the TH-517AB is its versatility. The machine is specially engineered to hammer and smooth a wide variety of leather uppers. Whether dealing with soft calfskin, firm cowhide, or synthetic leathers, this machine effectively reduces surface creases and wrinkles, making the leather appear more uniform and visually appealing. The hammering mechanism works by applying rhythmic, controlled pressure to the upper surface, flattening out uneven textures without damaging the material. This process ensures that the shoe’s upper looks fresh and professional before final assembly or finishing.

Digital Temperature Controller with Precise Adjustment

Equipped with an advanced digital temperature controller, the TH-517AB allows operators to set and maintain a precise working temperature ranging between 300 and 400 400°C. This temperature range is ideal for softening most types of leather without burning or over-drying. The digital display ensures real-time monitoring of heat levels, providing consistent heating and eliminating guesswork. This control is critical to achieving optimal wrinkle removal, as temperature fluctuations can adversely affect leather quality.

Strong Penetrating Steam Spray with Hot Air and Rolling Iron

The wrinkle removal process uses a unique combination of strong penetrating steam spray and hot air blow, which work synergistically to soften the upper’s surface. Steam deeply penetrates the leather fibers, increasing flexibility by temporarily breaking down the hydrogen bonds in the collagen matrix of the leather. Immediately following the steam treatment, a powerful hot air blast removes excess moisture and prepares the surface for rolling. This combination ensures that the leather is pliable but dry enough for the next step, rolling with a rolling iron. The rolling iron then repeatedly presses and rolls over the leather, mechanically smoothing out wrinkles and folds, resulting in a perfectly smooth and shiny surface. This process mimics skilled manual ironing but with far greater efficiency and uniformity.

Adjustable Hammering Frequency for Material Sensitivity

The machine’s hammering frequency is fully adjustable to suit different types of shoe uppers. Softer leathers require gentle hammering to avoid damaging the grain, while tougher materials can tolerate more intense hammering to remove stubborn wrinkles. This feature makes the TH-517AB adaptable to a wide range of leather types and product specifications, giving manufacturers flexibility in producing diverse footwear collections.

Adjustable Gas Temperature and Ratio for Cortex Sensitivity

Leather types vary not only in softness but also in their cortical properties (the outer layer’s thickness and toughness). The TH-517AB allows operators to adjust the temperature and ratio of mixed gases used in the steam generation process, tailoring the steam quality to the specific cortex of the leather upper. Fine-tuning these parameters optimizes steam penetration and surface softening, ensuring that the wrinkle removal process is both effective and gentle on the material.

Energy-Efficient Steaming with 30-Second Cycle

The steaming time for each leather upper is set to just 30 seconds, which is significantly shorter than many traditional steam wrinkle removal machines. This translates to an impressive 60% energy saving compared to ordinary models, making the TH-517AB an environmentally friendly and cost-effective choice. Reduced steaming times also speed up production cycles, allowing manufacturers to increase throughput without sacrificing quality.

Safe Heating Wire Protection for Durability

Safety and longevity are priorities in the design of the TH-517AB. The machine incorporates a heating wire protection function that safeguards the internal heating elements against overheating and electrical faults. This protection system prolongs the life of the heating components and prevents downtime caused by equipment failure, ensuring continuous and reliable operation.

Accurate Water Level Control System

Steam generation depends heavily on precise water management. The TH-517AB is equipped with an accurate water level control function that continuously monitors and maintains the water supply within optimal levels. This prevents interruptions in steam production and protects the boiler from damage caused by running dry, improving both machine efficiency and safety.

Technical Parameters

• Voltage: 380V, suitable for industrial environments

• Power: 5.8 kW for robust heating and steam generation

• Weight: 82KG net, 105KG gross including packaging

• Size: Compact footprint of 4996172cm, fitting easily into production lines

These specifications highlight the TH-517AB’s balance of power, portability, and operational convenience.

Operational Insights

How It Works

The operator places the leather upper on the ironing platform, positioning it for the hammering and wrinkle removal cycle. Upon activation, the machine’s heating element raises the temperature to the preset level. Simultaneously, steam is generated and sprayed onto the leather surface, softening the fibers. Hot air is then blown across the surface to remove moisture while keeping the leather warm and flexible. The rolling iron mechanism continuously presses and rolls over the leather surface, while the hammering system delivers adjustable impacts to flatten out wrinkles. The entire process takes approximately 30 seconds per piece, allowing for high throughput in production environments.

User Control and Adjustments

Operators have full control over temperature settings, hammering frequency, and gas mixture ratios via the digital interface. These controls allow for fine-tuning based on the leather type, thickness, and desired finish. The intuitive digital panel simplifies operation and reduces the learning curve for new users, while safety features like water level and heating wire protection provide peace of mind.
