TECHNICAL PARAMETER

The TH-211 Heel Seat Steaming Machine is a state-of-the-art industrial footwear processing solution designed to meet the rigorous demands of modern shoe manufacturing. It offers an integrated, high-performance platform for steam-based softening, bonding, and wrinkle-removal tasks associated with heel seat preparation. This machine brings innovation to the shoemaking process by combining precision engineering, intelligent temperature control, and robust construction for superior results. Whether it’s working with leather, synthetic fabrics, or high-viscosity PU materials, the TH-211 ensures a flawless finish that enhances both the aesthetics and structural integrity of the shoe.

Advanced Steam Integration for Perfect Uppers

The TH-211 Heel Seat Steaming Machine has been engineered to streamline the process of softening and preparing the heel area of shoe uppers. By utilizing a powerful high-temperature steam system, it efficiently eliminates internal tension, smooths out creases, and ensures the leather conforms perfectly to the heel mold. This creates a wrinkle-free, smooth, and ergonomically consistent fit in the heel zone, an area where structural perfection is crucial for shoe comfort and durability. Steam is directed with precision to the heel seat, targeting the exact areas that require softening without unnecessary dispersion. This results in minimized steam wastage, faster processing times, and improved control for the operator. Whether you're working with natural leather, PVC-coating materials, or thick PU, the TH-211 adapts seamlessly to each type, delivering high-quality, consistent results.

Ideal for Hot Melt Adhesive and Lining Fusion

A standout feature of the TH-211 is its compatibility with hot melt adhesive and hot melt adhesive tape processes. This makes it the perfect choice for manufacturers who require strong bonding between uppers and linings. It merges materials using heat and pressure in combination with steam, achieving superior adhesion with reduced operational complexity. The fusion of adhesives with shoe uppers and linings is often a multi-stage process, but the TH-211 consolidates these steps. The steam not only softens the upper but also activates the adhesive simultaneously, resulting in a smooth bond without misalignment or air pockets. This one-step process increases productivity, lowers energy consumption, and significantly reduces the risk of upper material damage during processing.

All-in-One Softening and Bonding System

The machine is especially beneficial for manufacturers seeking to enhance the production efficiency of leather shoes and sneakers. Its integrated steam-based softening and bonding operations enable workers to complete multiple tasks in a single pass. There is no need to pre-soften the leather or separately bond linings and adhesives; every stage happens concurrently. This not only saves time but also reduces handling of materials, minimizing the risk of creasing or scuffing sensitive upper materials. Moreover, by combining these processes, the machine reduces mechanical wear and tear on the uppers. This preserves material quality and prolongs the lifespan of the finished footwear.

Wide Material Compatibility

Versatility is at the heart of the TH-211’s design. It supports a wide range of materials commonly used in footwear manufacturing, including:

• Genuine leather

• Synthetic leather

• Thick PU (polyurethane)

• PVC-coated materials

• Textiles and blended uppers

• High-adhesion lining materials

This flexibility means that factories can use a single TH-211 machine for multiple types of shoes, from formal leather shoes to fashion sneakers, reducing the need for multiple pieces of equipment and simplifying the production floor layout.

Durable and Corrosion-Resistant Construction

The TH-211 is built for industrial-grade reliability. Its boiler and internal piping system are made of stainless steel, chosen specifically for its resistance to corrosion and high temperatures. This ensures that the steam remains clean and uncontaminated, preserving the integrity of the materials being processed. Traditional machines often suffer from internal rust or mineral buildup, which can cause discolored water or foul odors that damage the fabric or affect the bonding process. With stainless steel components, the TH-211 eliminates this risk, providing consistently clean and safe steam, essential for high-quality shoemaking. In addition, the machine is designed with a sturdy frame and a powder-coated finish that resists scratches, impacts, and moisture damage, even in high-humidity factory environments.

Intelligent Temperature and Pressure Control

Precision matters when working with heat and steam. The TH-211 is equipped with an intelligent temperature controller that enables operators to fine-tune settings based on the materials and shoe models in production. This flexibility allows you to optimize heat exposure for delicate leathers or ramp it up for tough synthetic composites. The boiler temperature is governed by a dual control system that prevents overheating. This system offers not only efficient heating but also safety assurances, avoiding risks of burning materials or endangering staff. The steam pressure is also adjustable, enabling the operator to increase or reduce force depending on the upper’s thickness and stiffness. To further enhance safety, the boiler includes an overpressure protection device and an emergency steam exhaust function. These systems automatically activate if the pressure exceeds safe limits, ensuring that your operations remain secure.

Flexible Operation Modes: Manual and Automatic

Not all production lines are the same. That’s why the TH-211 offers both manual and automatic operating modes. In manual mode, skilled operators can directly control steam output and pressure duration, allowing for precise customization during prototyping or when working with non-standard materials. In automatic mode, the machine follows preset cycles for consistent results, perfect for high-volume production environments. This mode increases throughput while maintaining quality, making it easier to meet tight deadlines and handle bulk orders without compromising craftsmanship. The shift between modes is seamless, allowing operators to adapt quickly depending on production requirements.

Steam Suction and Humidity Control

A common problem in shoe factories using steam equipment is the increase in workshop humidity, which can negatively impact both worker comfort and other processes like adhesive curing. The TH-211 addresses this with built-in suction equipment on its air jet pipes. This system immediately draws away excess steam after each operation, preventing it from dispersing into the work area. This suction mechanism not only helps maintain ideal ambient humidity levels but also contributes to a cleaner, safer environment for operators. The reduced moisture accumulation also protects other equipment from long-term steam exposure damage.

Easy to Use, Trusted by Professionals

Despite its advanced features, the TH-211 is remarkably easy to operate. Its ergonomic controls and intuitive interface allow workers of varying experience levels to operate the machine efficiently. The controls are clearly labeled, and the process indicators offer real-time feedback on steam temperature and pressure, making operation transparent and predictable. This ease of use has made the TH-211 a favorite among professionals in shoe factories across multiple regions. It has proven structural performance, with minimal downtime and consistent quality over long production cycles. Many long-standing customers continue to trust this model for their heel seat preparation needs due to its reliability, durability, and high performance.

High Production Capacity

In today’s competitive manufacturing environment, capacity matters. The TH-211 can process up to 1,500 pairs of shoes in an 8-hour shift, making it one of the most efficient machines in its class. This output enables medium to large-scale manufacturers to meet demanding production schedules without needing multiple machines or extra operators. Its energy consumption remains efficient even at high loads, and the heating elements are optimized to deliver rapid startup times and stable performance across extended operations.

Compact Design and Portability

With a space-conscious footprint of approximately 82 cm in length, 52 cm in width, and 145 cm in height, the TH-211 is ideal for factories where floor space is at a premium. Its relatively compact design allows for easy integration into existing production lines. Weighing in at around 120 kilograms, the unit is stable yet portable enough to be moved with minimal effort. Heavy-duty casters can be added to the base for mobility, making it easier to reposition the machine during workflow changes or maintenance routines.
