How to Optimize Lasting Machines for Special Shoe Shapes with Adjustable Claws?

Product Introduction

Guangdong Tenghong Machinery Technology Co., Ltd., founded in 2000 and located in Dongguan City, China, is a reputable manufacturer dedicated to producing high-quality shoe making equipment. The company offers a diverse product range including toe lasting machines, hydraulic heel seat lasting machines, sole attaching machines, and advanced automatic servo lasting machines. Among its innovative products is the TH-N737A 9 Pincers Hydraulic Automatic Toe Lasting Machine, designed to meet the high demands for precision, versatility, and efficiency in shoe manufacturing.

The TH-N737A features a fully hydraulic operated system and nine finely adjustable, quick-changeable pincers mounted on a double tracking pincer plate. This machine is optimized for special shoe shapes with its automatic turning inward pincers for better inner lasting and adjustable pincers to ensure balanced tension across different upper materials. With an upward stroke of the last support adjustable externally and a two-step upward movement to prevent slipping, the TH-N737A is built for reliable and precise lasting.

This machine achieves high production efficiency of 1,600 pairs per 8 hours with power rating of 2.7 KW and dimensions suited for factory integration. Its technological features ensure superior glue points, tensile balance, and lasting perfection, making it a preferred choice for professional shoe manufacturers aiming for quality and productivity.

Product Features

The TH-N737A Hydraulic Automatic Toe Lasting Machine excels through a suite of advanced features designed specifically for the complexities of lasting special shoe shapes. Its fully hydraulic operated system offers consistent power and smooth, precise control, a marked improvement over pneumatic or mechanical systems, assuring lasting accuracy.

Central to the machine’s flexibility is its set of nine finely adjustable pincers mounted on a double tracking pincer plate. These pincers can be quickly exchanged or adjusted to accommodate different shoe lasts and design requirements, enhancing the lasting quality for special shoe shapes. The pincers’ automatic turning inward along the left and right sides increases the lasting quality of the shoe's inner part, ensuring that difficult-to-last areas are addressed effectively.

Each left and right pincer pair can operate in either automatic pulling or manual mode, ensuring tension balance across different materials in the shoe upper. This function helps prevent uneven stretching which can compromise the adhesive bond or deform shoe structure. This means that for mixed-material uppers or intricate designs, manufacturers gain a machine capable of adapting seamlessly.

The ability to adjust the upward stroke of the last support via an external knob is a vital ergonomic and productivity feature. Operators can quickly and precisely modify support height, improving alignment and reducing setup times. Additionally, the two-step upward movement function prevents last slippage when combined with heel support operation, contributing to lasting consistency.

Adjustments of the applicator width are also swift and straightforward, enabling the machine to reach perfect glue points on the insole corresponding to varying shoe sizes. This feature is crucial in ensuring glue is uniformly applied at optimal areas, reinforcing the lasting bond and reducing waste.

The toe pusher mechanism includes adjustable two-step pressure options. The initial pressure movement can be configured as either pressure-controlled or position-controlled, providing operational flexibility and enabling fine-tuning for different shoe materials and designs. The no-step variable speed forward movement of the wiper mechanism further enhances process control, smoothing the insole adhesive application.

Standard attachments like the auxiliary wiper, side pusher, and toe projector mechanisms complete the system by optimizing glue spreading, pushing positions, and toe lasting accuracy.

Collectively, these features empower the TH-N737A to deliver high-quality lasting even for challenging shoe shapes, promoting production efficiency and exceptional product integrity.

Manufacturing Craftsmanship and Production Advantages

Guangdong Tenghong Machinery Technology Co., Ltd. emphasizes quality and innovation in the manufacture of the TH-N737A. The company maintains stringent quality processes compliant with ISO9001:2008 standards, utilizing durable materials and precision components to build lasting machines capable of enduring heavy industrial use.

The hydraulic system ensures stable and consistent power application, reducing vibration and mechanical wear, which preserves component lifespan and reduces maintenance needs. This stable force is critical in achieving uniform glue application and lasting tension, especially for complicated shoe lasts or composites.

Adjustable pincers and ergonomic external controls reduce setup and changeover times, enabling manufacturers to switch quickly between shoe models or sizes. This agility reduces factory downtime and labor costs, contributing to higher throughput. The machine’s large capacity and intelligent design allow a productivity rate of 1,600 pairs in an 8-hour shift—beneficial for large-scale production contexts.

Advanced technological features, including digital control systems and quick exchangable pincers, reduce operator error and improve repeatability. This results in a more reliable process that consistently meets stringent quality control measures aimed at competitive shoe manufacturing.

The comprehensive design of auxiliary mechanisms improves glue laying and lasting pressure application, minimizing adhesive waste and enhancing the durability of final products. These operational advantages translate into fewer returns and better brand reputation in the market.

Guangdong Tenghong supports customers with pre-sale consultation, production line planning, on-site installation, training, and after-sales services, ensuring clients maximize the machine's potential and maintain smooth operation.
