This machine is engineered for precision, ease of use, and high-capacity performance, offering seamless integration into the footwear production line. It is especially ideal for softening shoe toes with steam in preparation for bonding with hot melt adhesive, ensuring a tight fit, smooth finish, and strong structural integrity in the toe area of all types of footwear. From fashion-forward sneakers to durable work boots and elegant dress shoes, the TH-212 supports the essential pre-molding phase of toe preparation with accuracy, speed, and temperature-controlled consistency. Built for volume manufacturing, it delivers professional results at an industrial scale while offering safety and energy efficiency through intelligent controls and ergonomic design.

Engineered for Precision Toe Steaming

The toe box of a shoe is one of its most visible and functionally important parts. Achieving a smooth, well-fitted toe finish requires precise heat and pressure application to soften the upper and lining before final shaping and bonding. The TH-212 meets this need with a specialized dual-mold system, enhanced with steam delivery and temperature-adjustable settings. Once the toe upper is inserted by hand into the machine’s working area, the process becomes automatic. Steam is delivered directly to the contact zones between the upper and the forming mold, allowing the material to become soft, pliable, and ready for final shaping. This steam softening ensures that the toe adopts a wrinkle-free contour and adheres perfectly to the mold shape with superior hold strength when used in conjunction with hot melt adhesives. The intelligent integration of steam and mold temperature ensures optimal results across various types of materials, including synthetic leather, genuine leather, PVC-coated textiles, PU, and technical fabrics.

Automatic Operation with Dual Control Position

At the heart of the TH-212’s performance is its automatic dual-position control system, designed for seamless, intuitive operation. The operator simply places the toe upper into the correct position, and the machine begins its operation cycle automatically. This eliminates unnecessary delays, improves workflow, and reduces reliance on manual intervention, enabling workers to process more pairs in less time. This semi-automated process not only reduces fatigue for the operator but also ensures consistent output and reduces the risk of human error. The automatic activation, triggered by toe insertion, aligns with lean manufacturing principles by cutting unnecessary wait times and ensuring a fluid assembly line. The control panel is located near the operator's working position for fast, intuitive command access. With two operational positions, the machine can support alternating operation, effectively doubling productivity without the need for two machines.

Space-Saving and Ergonomic Design

In busy production environments, space efficiency is key. The TH-212 is designed with a compact footprint, offering high-volume capability without occupying excessive floor area. With carefully considered dimensions, the unit fits comfortably into small workstations while still allowing easy access to key components for operation and maintenance. The runner design of the machine’s cylinder start switch is particularly noteworthy. This clever design not only provides convenient activation but also ensures minimal space consumption. The switch is integrated smoothly into the machine body, enhancing safety and reducing the likelihood of accidental triggering. The front-mounted sliding groove button allows operators to control the vertical motion of the upper mold. This button is conveniently located in line with the operator’s natural hand movements, further optimizing ergonomics and reducing training time for new staff.

Advanced Temperature Control for Upper and Lower Molds

Accurate temperature regulation is crucial when working with steam and heat-sensitive materials. The TH-212 features independent temperature controls for its upper and lower molds, ensuring adaptability across a wide range of shoe designs and material types.

• The upper mold, which applies heat and pressure from above, has a factory-set default temperature of 100°C. This setting is ideal for softening upper materials without risking overexposure or material deformation.

• The lower mold, which supports the toe structure during steaming and heating, is fixed at a default of 120°C, providing a slightly higher temperature to assist in the adhesive bonding process and help form a strong toe cap structure.

Both the upper and lower temperatures can be manually adjusted to suit specific production requirements. This makes the TH-212 extremely flexible and well-suited to different shoe lines, from delicate women's fashion shoes to rugged outdoor footwear. Operators can modify these settings easily through the machine's control interface, which displays real-time temperature information and ensures rapid response to production changes.

Seamless Adhesive Activation and Upper Bonding

The TH-212 is specifically optimized for use with hot melt adhesives—a common bonding solution in modern shoe manufacturing. As the steamed and softened toe upper is shaped and heated within the molds, the adhesive melts and adheres the upper to the toe structure in one integrated cycle. This one-step process eliminates the need for separate adhesive application and heating stations, streamlining production and improving output consistency. By integrating steaming and hot melt activation, the TH-212 minimizes adhesive waste, prevents air bubbles or separation, and enhances the overall finish of the shoe toe. Moreover, the high thermal conductivity of the molds ensures that heat is distributed evenly across the upper’s contact surface, helping create a smooth bond line and enhancing product durability. This level of precision bonding is difficult to achieve with traditional, manual heating methods and results in fewer quality control issues.

Built for Safety, Reliability, and Long-Term Use

Industrial machinery must offer more than just performance—it must also be safe and durable. The TH-212 is constructed with high-quality components, including corrosion-resistant internal piping for steam delivery, stainless steel contact surfaces, and reinforced structural panels. These features extend machine life and ensure clean, consistent steam for every cycle. The intelligent control panel includes built-in thermal overload protection, emergency stop controls, and pressure limit safeguards, ensuring safe operation under all working conditions. Operators are shielded from steam exposure, and all heating surfaces are insulated to reduce heat loss and accidental burns. Additionally, the low-maintenance design includes accessible service panels, a robust cooling system, and modular components, enabling easy cleaning, inspection, and replacement of parts. This reduces downtime and supports continuous operation in high-pressure manufacturing environments.
