Product Features of the TH-316 Two Hot and Two Cold Shoe Toe Moulding Machine

Advanced Dual Hot and Cold Molding Stations

• The TH-316 features a dual-station design that includes two hot molds and two cold molds working simultaneously, significantly increasing production efficiency. While the hot molds soften shoe uppers through steam application, the cold molds use a direct-cooling refrigeration system to rapidly solidify shapes, completing the formation cycle swiftly.
• Steam devices integrated into the hot molds enhance the flexibility and brightness of uppers by softening materials uniformly, critical for precise toe molding.
• The rapid water-cooling system reaches temperatures as low as -30℃, allowing the toe caps to set firmly within just five minutes, helping factories meet high volume demands without compromising quality.
• The machine operates with 220V power and consumes 4kW, balancing high performance with energy efficiency.
• Dimensions of 87×90×150 cm and a weight of 570kg combine compactness with industrial stability, suitable for factory production lines.

Adjustable Middle Claw for Flexible Last Handling

• The middle claw’s adjustability is vital for accommodating the variations in shoe lasts used across different footwear styles, from casuals to formal shoes or boots. Its ability to move and adjust precisely ensures secure and perfect gripping of lasts of varying shapes and sizes.
• This adjustment flexibility prevents slippage or deformation during the molding process, which is essential to maintain the shoe’s design integrity and quality.
• Matched with customizable Teflon straps and last components—crafted specifically to clients’ lasts with 98% accuracy—the middle claw’s adaptability guarantees optimal mold tightness and uniform pressure distribution.
• The precision and flexibility of the middle claw enable manufacturers to switch between product lines seamlessly, increasing operational efficiency and reducing downtime.
• This feature also supports diverse shoe materials and upper textures by ensuring that pressure and grip are modulated accordingly for each pair produced.

User-Centric Design for Efficiency and Quality

• The machine offers both manual and PLC-controlled operation modes, allowing production lines to scale labor and automation as needed, reducing errors, and optimizing throughput.
• The adjustable Teflon tightening devices complement the middle claw by providing a non-stick, resilient gripping surface that protects delicate uppers during molding.
• This combination provides a better forming effect, improving the overall appearance and functional durability of shoe toes.
• Operators benefit from a stable column runner system, which ensures precise and smooth machine movements with minimal vibration.
• The machine’s capacity of 1600 pairs per 8 hours meets the needs of medium to large shoe factories aiming for high-quality, consistent output.

Application Cases Demonstrating the Importance of Middle Claw Adjustability

Multi-Style Shoe Production Lines

• Factories producing diverse footwear lines — including sports shoes, boots, and casuals — rely on the TH-316 for its ability to adapt to different last shapes without compromise. The adjustable middle claw makes rapid product changeovers possible, ensuring consistent toe molding for all styles.
• The machine’s reliable adjustability reduces scrap and rework, lowering production costs and improving factory yield.

Premium Footwear Manufacturing

• Luxury shoe manufacturers value the precision middle claw mechanism for molding delicate, high-end shoe uppers. The claw’s capacity to finely adjust grip pressure retains the integrity of premium materials like soft leathers and specialty textiles.
• This helps maintain product quality and aesthetic, enhancing brand reputation and consumer satisfaction.

Mass Production for Comfortable and Durable Shoes

• High-volume shoe producers benefit from the TH-316’s automated molding cycle combined with flexible middle claw settings, achieving rapid throughput without sacrificing durability or comfort.
• The machine supports consistent structural accuracy, which contributes to long-lasting shoe designs favored by clients worldwide.
