  • Digital speed and micro-adjustment control

  • Real-time parameter display

  • Simplifies adjustments and increases operational precision

  • Operators can quickly learn and use the interface, reducing training time

Three-Stage Mechanical Design with Electronic Ruler Precision

This model adopts a three-stage toe lasting mechanism. Each section is independently optimized using electronic ruler feedback, allowing the machine to conform to the natural curve of any shoe last.

• Precision Benefits:

  • Follows the shoe’s arc precisely

  • Enhanced toe shape consistency

  • Perfect for shoes with curved or non-standard toe designs

Optimized Toe Shaping via Sectional Arrangement

The three-section design is intentionally configured to reflect the natural curvature of most shoe types, offering a more natural and snug fit during toe formation.

• Outcome:

  • Enhanced aesthetics and comfort

  • Perfect toe shaping with reduced defects

  • Uniformity across large production batches

Advanced Hydraulic and Circuit Systems

The TH-747MA incorporates a hydraulic drive system complemented by high/low voltage circuit design, ensuring stable, smooth, and safe operation under continuous use.

• Engineering Benefits:

  • Improved machine stability under pressure

  • Reduced risk of malfunction

  • Long service life under heavy-duty production conditions

PLC System with Graphic Touch Interface

Equipped with an intuitive PLC control system, the machine allows operators to control every mechanical and timing function easily. It also provides graphic data visualization for improved diagnostics and system control.

• Control Features:

  • Stores up to 100 shoe-lasting configurations

  • Saves pincer location and lasting parameters

  • Quickly switch between shoe models

  • Prevents downtime during shoe style transitions

Security-Enhanced Parameter Setting

All stroke and time parameters are numerically set and protected via a key switch security system, ensuring only authorized personnel can modify sensitive settings.

• Security Features:

  • Prevents unauthorized access

  • Reduces production inconsistencies

  • Maintains quality control

Comprehensive Diagnostic and Error Reporting

The TH-747MA includes a built-in error diagnostic system, reducing troubleshooting time and enabling quicker recovery during faults or operational anomalies.

Pincer Functionality and Customization

Nine Independent Pincers for Flexible Toe Lasting

The TH-747MA utilizes nine fully adjustable pincers, each capable of independent control for fine-tuning the grip on different shoe upper materials and toe shapes.

• Precision Control:

  • Enhanced fit for various shoe styles

  • Perfect for complex or custom footwear designs

  • Maintains shape integrity during forming

Middle Pincer with 15° Bidirectional Deflection

The central pincer offers up to 15 degrees of movement to the left or right. This allows it to accommodate asymmetric toe caps and fashion footwear requiring unique shaping dynamics.

Automatic Rotation for Fifth Pincer

To improve the lasting effect on the inner waist, the fifth pincer can be set to perform a rotational movement, achieving a better contour around curved areas.

Manual and Automatic Pincer Adjustments

Operators can choose between:

• Manual lift/lowering

• Automatic pull-down stroke setting

This flexibility ensures that the vamp tension is optimized for a secure fit during the lasting process.

Individual Group Pincer Control

Once the vamp is secured, the pincers within the group can be manually released or clamped, providing the operator with complete control over the shaping process.
