Product Features of the TH-715A Automatic Generally Hydraulic Sole Attaching Machine

Full Hydraulic System for Powerful and Precise Operation

• The TH-715A integrates a robust full hydraulic system that provides consistent pressure control with oil pressure rated at 40kg/m³. This delivers strong and even pressing needed for reliable adhesion between midsoles and uppers.
• The machine includes eight adjustable side pressing blocks, each 80mm high, positioned to ensure uniform pressure application around the sole's perimeter.
• Adjustable band distance with two sections allows the machine to accommodate a wide range of shoe last sizes, from 140mm to 400mm in length and up to 190mm in height.
• Each movement within the machine is equipped with pressure adjustment functions, enabling precise control adapted to different shoe styles and materials, improving overall product quality.
• Powered by a 2.2kW pump, the machine balances energy efficiency with the force required for heavy-duty production environments.

Versatile Functionality Covering Multiple Pressing Needs

• The TH-715A can perform bottom pressing, edge pressing, and front and back pressing either independently or simultaneously, depending on production requirements.
• The machine’s flexible operation is suitable for complex sole shapes such as dragon boat soles and wall-wrapped sports shoe soles, enhancing the ability to produce diverse footwear efficiently.
• Its high output capacity supports continuous production while saving labor by automating what previously required extensive manual effort and skill.
• Compact dimensions (97 × 75 × 145 cm) and a total weight of 430 kg enable easy factory placement while ensuring machine stability during operation.

User-Friendly and Labor-Saving Design

• Designed for ease of operation, all pressure adjustments are conveniently located, allowing operators to optimize pressing parameters quickly.
• The machine’s automation reduces fatigue and potential errors associated with manual gluing and pressing, contributing to more consistent production quality across shifts.
• Guangdong Tenghong offers options for customization such as auxiliary pressing devices, adapting the machine’s performance to client-specific needs.

Application Cases Demonstrating TH-715A’s Effectiveness

Efficient Sole Attaching in Sports Shoe Manufacturing

• Sports shoe producers have integrated the TH-715A to glue midsoles and uppers with superior precision and adhesion, accommodating varied sole constructions that include complex wrapped edges.
• Automation not only increased production volume but also minimized defects and returns, facilitating stronger buyer confidence and reduced labor costs.

Adaptation in Casual and Boat Shoe Production

• Factories specialized in wall-type sole construction benefit from the machine’s adjustable band distance and side pressing blocks, which enable consistent results on multiple models without lengthy machine reconfiguration.
• The TH-715A’s capability to perform all pressing operations simultaneously helps accelerate workflow and optimize plant floor space.

Versatile Use in Mixed Production Environments

• Manufacturers producing diverse shoe lines appreciate the TH-715A’s ability to switch pressing modes easily, supporting efficient small-batch production alongside mass manufacturing.
• Its compact footprint suits production facilities with limited space while ensuring high output and quality.
