What is the maximum output of your production line?

The maximum output can reach 3,000 kg/h. Actual output may vary based on specific configuration and process requirements.

Which blowing agents are supported?

We support a wide range of blowing agents, including CO₂, ethanol, butane, DME, HFC, LPG, HFO, pentane, freon, etc. For the Russian market, we also provide solutions compatible with isobutane blends, with butane mixtures being generally recommended.

What is the density range of the products?

The typical density range is 24–50 kg/m³. Under specific process conditions, ultra-low densities of 21–22 kg/m³ can be achieved.

What is the maximum compressive strength?

The maximum compressive strength exceeds 1,200 kPa, meeting requirements for high-performance structural applications.

What is the available thickness range for XPS boards?

The thickness ranges from 10–200 mm, and custom sizes are available upon request.

What is the width range of the XPS foam boards?

The standard width is 600–1,200 mm. Non-standard widths can also be customized.

Laminating Machine for PS Underlayment Boards

Precision Secondary Foaming Oven

Our secondary foaming oven serves as the core molding equipment in the PS underlayment production line, specifically designed to apply precise heat treatment to the initially foamed sheets after gas release. Through accurate temperature control and air velocity management, it reactivates the blowing agents within the sheet, achieving perfect secondary expansion and final setting. This process ultimately forms the finished board with a stable, high-strength closed-cell structure.

Core Technical Features

Uniform and Efficient Heating System: Utilizes multi-zone independently controlled heating units combined with a forced convection circulation system, ensuring stable and uniform hot air flow within the oven.
Guarantees consistent heating across the width and length of the sheet, fundamentally eliminating issues like deformation, shrinkage, or foaming density variations caused by localized heat unevenness.

Precise Temperature Control and Synchronized Conveyance:

Equipped with high-precision temperature sensors and an intelligent PID control system, maintaining the operating temperature stably within the required process The conveyor speed intelligently matches the temperature profile, ensuring each section of the sheet completes the foaming and curing process according to the preset optimal parameters.

Optimized Air Velocity and Pressure Design:

The air ducts are optimized using Computational Fluid Dynamics (CFD), enabling uniform air velocity and pressure across the entire working width.
This uniform heat exchange environment is crucial for forming a uniform, dense cellular structure and is key to achieving high compressive strength and excellent dimensional stability in the product.

User-Friendly Operation and Intelligent Monitoring:

Integrated into the production line's main control system, allowing operators to monitor the temperature, air velocity, and conveyor status of each zone in real-time.
Features process parameter storage and recall functions, supporting quick switching between different product recipes, and is equipped with a safety alarm system to ensure operational safety.
