Russia’s Cold Chain Industry Addresses Truck Panel Delamination with Automatic Hot Press Technology

With the growth of cold chain logistics, food transportation, and insulated vehicle manufacturing in Russia, refrigerated truck manufacturers are placing greater focus on panel quality, structural stability, and production consistency. Refrigerated truck body panels are commonly manufactured using FRP skins, polyurethane foam cores, and structural adhesives, requiring accurate hot pressing processes to achieve reliable bonding between different materials.

During composite panel production, issues such as adhesive delamination, internal bubbles, and uneven panel surfaces may affect the long-term performance of vehicle bodies. In Russia’s cold climate conditions, refrigerated vehicles often operate in low-temperature environments, creating higher requirements for panel sealing performance and composite structure reliability.

Therefore, when selecting production equipment, manufacturers need to evaluate key factors including temperature control accuracy, pressure distribution, and automation capability.

The single layer automatic hot press machine for vehicle body panels is designed for refrigerated trucks, insulated vehicles, and special vehicle composite panel production. The system integrates automatic loading and unloading, hydraulic pressing, temperature-controlled heating, and PLC intelligent control.

The machine uses thermal oil circulation heating technology to provide uniform heat distribution across the upper and lower platens. With temperature control accuracy of ±1℃, the system supports stable curing conditions for polyurethane adhesive and structural glue, helping reduce defects caused by uneven heating.

For Russian refrigerated truck manufacturers, stable hot pressing conditions provide a foundation for more standardized composite panel production processes.

In addition to temperature control, pressure distribution plays an important role in refrigerated truck panel manufacturing. Composite panels often include lightweight core materials such as polyurethane foam. Uneven pressing force may result in surface deformation or poor bonding quality.

The automatic hot press machine uses multi-cylinder synchronous hydraulic driving with pressure compensation technology to maintain balanced force distribution during pressing. The equipment provides a maximum pressing force of 80 tons and a working platen size of 4600mm * 2650mm, allowing full-size vehicle panels to be processed in one pressing cycle.

The system is suitable for various composite structures, including FRP and PU foam panels, aluminum honeycomb panels, and wood-plastic composite panels.

Refrigerated truck panel production requires appropriate hot pressing parameters based on adhesive types and panel structures. Accurate temperature management is essential for consistent curing results.

A stable hydraulic system helps maintain uniform pressing force, allowing panel layers to bond properly and reducing production variations.

The PLC touch control system allows manufacturers to preset panel production parameters and automatically manage pressure holding, pressure release, and unloading processes.

By combining precision temperature control, synchronized hydraulic pressing, and automated operation, automatic hot press machines provide Russian refrigerated truck manufacturers with a standardized solution for composite panel production and reliable cold chain vehicle manufacturing.
