In the production of Polyester Fiber Acoustic Panels, consistent product quality depends not on a single machine, but on a well-designed and complete forming process. A professional production line clearly separates heating, forming, and cooling, with each stage handled by dedicated equipment.
1. Industrial Hot Air Circulation Oven – Material Preheating & Softening
Before forming, polyester fiber sheets are processed in an industrial hot air circulation oven, where the material is evenly heated and softened to achieve proper formability.
- A circulating air duct system ensures uniform heat distribution across the entire sheet
- The material is softened by hot air, not by direct contact heating, preventing localized overheating
- Direct heating on press plates or machines may cause surface burning, discoloration, or degradation of acoustic performance
For this reason, hot air preheating is a critical first step in producing high-quality polyester fiber acoustic panels.
2. Forming Press Machine – Mold Fixed, Pressure Forming
After several minutes of heating, the softened material is removed from the oven and placed directly onto the forming press machine for shaping.
- The mold is fixed securely on the press machine, ensuring stable positioning and consistent dimensions
- The primary function of the press machine is to provide stable and uniform forming pressure, not heating
- The softened material is pressed into flat or 3D shapes within the mold
This forming method is ideal for continuous and mass production, delivering reliable appearance and dimensional consistency.
3. Mold Cooling System – Fast Stabilization & Higher Efficiency
Since the material enters the forming stage at a high temperature, mold temperature will increase during continuous production. Without proper cooling, this can negatively affect forming efficiency and product stability.
Therefore, professional forming solutions are typically equipped with a dedicated mold cooling system:
- A water chiller or closed-loop cooling unit
- Water pipes connected to aluminum plates or internal mold cooling channels
- Rapid heat dissipation during or between forming cycles
An effective cooling system helps to:
- Shorten forming cycle time
- Improve shape stability
- Reduce spring-back and deformation
- Extend mold service life
4. Simplified Production Flow
Industrial Hot Air Oven → Forming Press Machine → Mold Cooling System
This combination of hot air softening, pressure forming, and cooling-assisted stabilization represents a mature, reliable solution for producing polyester fiber acoustic panels and 3D wall panels.
