Introduction to Celuka Foam Panel Tooling

Celuka Foam Panel Tooling is at the heart of producing high-quality PVC foam panels that have become indispensable in the interior design, furniture, cabinetry, wall cladding, and construction industries. With unique physical properties, durability, and aesthetic appeal, these panels are increasingly replacing traditional materials such as wood, MDF, and other conventional building products.

The key to achieving such high-performance panels lies in the Celuka foaming extrusion process, a highly controlled foaming technique that requires precision-engineered tooling. Celuka dies are designed not only to shape the panel but also to control its internal cellular structure, density, and surface finish, resulting in panels that combine lightweight design with superior mechanical and aesthetic properties.

What is Celuka?

Celuka is a controlled foaming process in which PVC, often blended with specific chemical foaming agents, is melted under high pressure and then extruded through a die. As the panel exits the die:

• The surface forms a dense, smooth skin layer.

• The internal core expands into a low-density foam.

This combination gives Celuka panels several advantages:

• Lightweight yet strong – easier to handle and transport than solid boards.

• Smooth, glossy surface – ideal for painting, printing, and lamination.

• Thermal and acoustic insulation – the cellular structure reduces heat transfer and dampens sound.

The result is a panel that is durable, versatile, and visually appealing, ready for a wide range of applications.

Technical Features of Celuka Foam Panel Tooling

The precision of Celuka tooling ensures that every panel meets exacting standards for dimensions, density, and surface finish. Key specifications include:

Main Components of a Celuka Foam Panel Die

1. Feeding Block (Material Distribution)
   Responsible for uniformly distributing molten PVC across the width of the die. Precise distribution prevents density variations and ensures even foaming in the panel core.

2. Die Lip & Calibration Section
   The die lip is carefully designed to create a smooth, skin-like surface, while the calibration section stabilizes the panel’s dimensions and ensures uniform thickness.

3. Gap Adjuster (Thickness Control)
   Operators can adjust the die gap with micron-level precision, tailoring the panel thickness to specific applications.

4. Cooling System
   Proper cooling of both the die and the extruded panel is essential to prevent deformation, maintain the skin layer, and stabilize the foam structure. Cooling can be done via rollers, air, or water baths, depending on the line design.

Advantages of Celuka Foam Panel Tooling

• Material Efficiency – The foaming core reduces PVC consumption, lowering production costs and panel weight without sacrificing strength.

• High Surface Quality – The skin layer provides a smooth, glossy surface suitable for painting, lamination, or direct printing.

• Thermal and Acoustic Insulation – Foam structure improves heat resistance and sound absorption, enhancing panel performance in building interiors.

• Durability – Resistant to moisture, UV radiation, chemicals, and moderate fire exposure, ensuring long-lasting panels.

• Versatility – Celuka panels can be used for furniture, wall panels, ceilings, signage, and industrial applications.

Applications of Celuka Foam Panels

1. Cabinetry and Washbasins – Waterproof panels for kitchens, bathrooms, and wet environments.

2. Refrigerator and Cold Storage Interiors – Lightweight panels with thermal insulation properties.

3. Wall and Ceiling Panels – Ideal for indoor spaces, especially in humid areas.

4. Lightweight Furniture – For offices, schools, and temporary installations.

5. Advertising & Signage – Panels provide a smooth printable surface for promotional boards, displays, and exhibition stands.

6. Flooring – Temporary or permanent lightweight flooring applications.

Production Process Using Celuka Tooling

1. Material Preparation
   PVC powder is combined with chemical foaming agents, lubricants, and thermal stabilizers to create a homogeneous mixture.

2. Extrusion
   The mixture enters a twin-screw extruder (e.g., ATP113 or ATP93), where heat and pressure melt the material uniformly.

3. Shaping & Die Exit
   Inside the Celuka die, the skin layer forms on the panel surface, while the core foams and expands to the desired density.

4. Calibration & Cooling
   Panels pass through calibration tables and cooling systems to stabilize thickness, flatness, and surface quality.

5. Cutting & Finishing
   Automated saws cut panels to size, creating a ready-to-use final product suitable for immediate application or further processing.

Important Operational Considerations

• Tool Maintenance – The die must be cleaned regularly to prevent surface imperfections caused by burnt PVC or foaming residues.

• Temperature and Pressure Control – Precise monitoring ensures proper skin formation and internal foaming.

• Die Lip Adjustment – Fine-tuning is critical during startup and product changes.

• Release Aids – Silicone oils or other release agents prevent sticking of molten PVC to the die surface.
