Key Features and Functional Highlights

Suitable for Various Shoe Types

• The TW-682AM is expertly engineered to accommodate a broad spectrum of footwear types:

  • High-Quality Shoes: Premium men’s and women’s shoes requiring superior finishing.

  • Children’s Shoes: Durable and comfortable moulding suitable for smaller, more delicate sizes.

  • Boots: Larger, tougher footwear needing reliable backpart shaping.

  • Sandals and Moccasins: Thanks to its versatile cold mould rotating mechanism, the machine is adaptable for open shoes and light footwear.

This flexibility ensures that the TW-682AM can be seamlessly integrated into diverse production lines without compromising quality or efficiency.

Advanced LED Position Light Projector

• A built-in LED position light projector ensures precise and accurate positioning of the backpart during the moulding process.

• This high-visibility indicator enables operators to achieve consistent moulding alignment, reducing errors and material waste.

• The projector’s illumination assists in low-light environments, facilitating exact placement and speeding up production cycles.

Independent Control of Pincers

• The machine features independent control for the inside and outside waist pincers, allowing for:

  • Oblique-Pulling Pincers Function: Both in the hot moulding station and the cold moulding station, pincers can be adjusted independently to apply optimal pressure and shaping force.

  • Quick and Easy Adjustment: Operators can tailor the pincer tension and angle according to the shoe style and material requirements without complicated procedures.

This unique design maximizes moulding precision and accommodates various shoe lasts and backpart designs.

Cold Mould Rotating & Wipe Device

• The cold mould is equipped with an integrated wipe device that ensures the upper material adheres smoothly and evenly to the last during moulding.

• Furthermore, the cold mould can rotate 180 degrees, enhancing operational flexibility.

• This feature is especially useful for moulding sandals, moccasins, and other shoes that require different shaping angles or repeated moulding passes.

Fast Change System for Cold and Hot Moulds

• The TW-682AM facilitates rapid switching between cold and hot moulds thanks to a specially designed fast-change system.

• This system is equipped with a robust fixing device to securely hold both cold and hot mould backparts in place during the moulding cycle.

• The quick-change capability significantly reduces downtime, allowing manufacturers to switch production styles swiftly and efficiently.

Cold Mould with Airbag for Optimal Moulding Effect

• The cold mould’s exterior is fitted with an airbag system that provides uniform pressure distribution.

• This airbag ensures the best possible effect during cold moulding by tightly wrapping the backpart around the last, preventing wrinkles, bubbles, or misalignment.

• The airbag technology enhances product consistency and improves overall shoe quality.

Hot Mould Using Silica Gel Material

• The hot mould incorporates silica gel materials known for their excellent heat resistance and flexibility.

• This design allows the hot mould temperature to reach up to 180 degrees Celsius, effectively moulding the shoe vamp to the last with superior adhesion.

• The temperature range of the hot mould guarantees that synthetic and leather uppers are evenly heated and shaped without damage.

Wide Temperature Range for Cold and Hot Moulds

• The cold mould temperature can be lowered to as low as -10 degrees Celsius.

• This wide temperature span from -10 to 180 degrees Celsius enables the TW-682AM to handle different materials and moulding requirements effectively.

• The ability to cool and heat accurately results in better vamp attachment and lasting, enhancing shoe shape retention and comfort.
