The TH-828 Chiller is a high-performance industrial machine designed specifically for the rapid cooling and shaping of shoe lasts and uppers in the footwear manufacturing process. Its state-of-the-art refrigeration system, combined with innovative engineering and precision control, allows for quick freezing of shoes after shaping, preventing deformation and ensuring a consistent, high-quality finish. This machine is an essential asset in modern shoe production lines, supporting enhanced productivity, reduced costs, and superior product quality.

Product Overview

The TH-828 Chiller is expertly crafted to handle the critical process of shoe cooling immediately following heat shaping. When shoe uppers are molded on lasts during manufacturing, they must be cooled quickly to set the shape firmly before removal. Failure to cool efficiently can lead to deformation of the shoe last or vamp, adversely affecting the shoe’s final shape and structural integrity. This machine employs advanced refrigeration technology to freeze the shoe bottoms after pressure shaping, rapidly bringing the temperature down to preserve the perfect form. The efficient cooling cycle prevents the shoe last from warping or distorting during the cooling process, maintaining the precise contours and fit designed in earlier shaping stages.

Core Functionality

The TH-828’s primary function is to rapidly cool shoe uppers and lasts immediately after the heat shaping process, effectively locking in the shape and preventing deformation or shrinkage that can occur when hot shoe materials are cooled slowly.

Why Rapid Cooling Matters

During shoe manufacturing, especially in processes involving heat molding or steaming, the shoe upper and last are often hot and pliable when removed from the shaping equipment. If left to cool at ambient temperatures, the material may warp or lose its precise shape, resulting in defects, increased waste, and higher production costs. The TH-828 Chiller reduces the shoe temperature quickly and uniformly, generally reaching -15 °C within minutes, a critical temperature range that stabilizes the shoe’s form for safe removal from the last without damage. This fast chilling also means that the production line is not delayed waiting for shoes to cool naturally, allowing manufacturers to maintain a high throughput with consistent quality.

Innovative Features for Enhanced Performance

The TH-828 integrates several advanced features that differentiate it from conventional shoe cooling equipment:

Double-Track Automatic Door System

• The machine incorporates double-track automatic doors, designed for durability and ease of use.

• This mechanism ensures quick and secure loading and unloading of shoe lasts, minimizing manual handling and production downtime.

• The smooth and reliable door operation enhances workflow efficiency and operator safety.

High-Quality Conveyor Belt

• Constructed from special, durable materials, the conveyor belt is engineered for long-lasting performance, minimizing wear and maintenance costs.

• The belt provides consistent movement and accurate positioning of shoe lasts through the cooling chamber, ensuring uniform chilling.

Automatic Defrosting Device

• To prevent mildew and buildup within the cooling chamber, the TH-828 includes an automatic defrosting system.

• This system periodically removes accumulated frost or moisture, maintaining optimal refrigeration performance and hygiene.

• Continuous defrosting prolongs machine life and reduces downtime for manual cleaning.

German Advanced Refrigeration Technology

• The machine features a refrigeration system based on advanced German technology, incorporating imported compressors and premium components.

• This system delivers rapid cooling speeds and efficient refrigeration, ensuring the interior temperature drops to the target level swiftly and remains stable throughout operation.

• The refrigeration components are carefully selected for reliability and longevity in demanding factory environments.

Uniform Cooling Distribution

• The refrigeration system is engineered for uniform temperature distribution within the chamber, eliminating hot spots or uneven cooling that could distort shoes.

• This consistency ensures every pair of shoes is cooled equally, maintaining product uniformity and reducing rejects.

Simple Operation and Maintenance

• The TH-828 Chiller is designed for ease of use, featuring an intuitive control interface that minimizes operator training requirements.

• Maintenance tasks are straightforward and accessible, allowing routine inspections and servicing without complex procedures or specialized tools.

How the TH-828 Chiller Enhances Production Efficiency

The advantages of incorporating the TH-828 into a shoe production line extend beyond mere cooling speed:

Faster Turnaround and Increased Output

• Rapid chilling shortens the overall production cycle by reducing the time shoes spend cooling after shaping.

• This acceleration allows shoe manufacturers to increase throughput and meet higher order volumes without compromising quality.

Superior Shaping Stability

• By stabilizing the shoe shape immediately, the machine reduces deformation risks associated with hot shoe handling.

• The shoe last’s integrity is preserved, allowing precise vamp-to-last conformity and consistent shoe dimensions.

Reduced Production Costs

• Improved process speed and fewer defective products translate directly into cost savings.

• The automatic defrosting and durable conveyor belt reduce downtime and maintenance expenses.

Enhanced Product Quality

• Uniform chilling maintains the leather or synthetic upper’s surface quality, preventing cracks, wrinkles, or gloss loss caused by uneven cooling or overheating.

• Shoes maintain their designed fit and form, meeting stringent quality control standards.

Operational Details

The TH-828 is engineered for seamless integration into shoe production lines. Here is a typical operational flow:

1. Loading: Shoes or boots, after shaping, are placed onto the conveyor belt. The double-track automatic doors open smoothly to allow loading.

2. Rapid Cooling Cycle: Once inside the cooling chamber, the refrigeration system activates, and within minutes, the shoes are cooled down to approximately -15 °C.

3. Monitoring: Sensors installed on the output prevent accidental shoe falls and help control the flow of finished shoes exiting the machine.

4. Unloading: After the cooling cycle, shoes exit the chamber smoothly and can be transported or processed immediately.

This operation ensures a continuous, efficient workflow that supports high production volumes with minimal manual intervention.

Temperature Control and Customization

While the standard temperature range covers normal room temperature down to -15 °C, the TH-828 offers customized temperature settings tailored to specific shoe materials or production requirements.

Manufacturers can specify particular cooling temperatures to optimize results for:

• Delicate leathers require gentler cooling

• Synthetic materials that may have different thermal sensitivities

• Boots or large footwear needing extended chilling time

This flexibility enhances the machine’s applicability across diverse product lines.
