Sandwich Panel Manufacturing Process

Materias primas​

Materias primas

Metal color-coated steel sheets (such as galvanized steel or aluminum) are selected and undergo surface coating treatments (e.g., PE, PVDF) to ensure weather and corrosion resistance. Core materials such as rock wool, glass wool, or PU/PIR are selected based on requirements, ensuring high density and stable moisture content.

Desenrollado activo

Desbobinado de bobinas de acero

In this process, automated equipment automatically uncoils metal sheets (such as color-coated or galvanized steel) and feeds them into the production line, preparing them for subsequent operations such as film lamination and plasma tension treatment.

Chapa de acero laminada

Chapa de acero laminada

A protective film is applied to the coated steel sheet to prevent scratches, stains, and surface damage during panel forming, lamination, transportation, and installation. It helps maintain the sandwich panel’s clean appearance and coating quality.

Activación de superficies mediante plasma

Tratamiento de tensión por plasma

Glostar employs plasma tension treatment technology to enhance the bonding strength between metal sheets and the core material; widely used in continuous sandwich panel production lines, this process is critical to ensuring the quality of the finished product.
Cortadora de algodón de cuatro cuchillas

Four-Blade Cotton Cutting

“Four-Blade Cotton Cutting” is a proprietary, patented foam/insulation cutting technology developed by Glostar, primarily used for the rock wool cutting stage in sandwich panel production. This technology is a key process for enhancing both production efficiency and the quality of the finished sandwich panels.

Almohadilla de algodón con bisagra

Hinged Cloth-cotton Pad

Glostar utilizes the “Hinged Cloth-cotton Pad”—an advanced, domestically pioneering composite process—which primarily serves to enhance the sandwich panel’s flexural load-bearing capacity and prevent the formation of creases.

Transporte automático de lana de roca

Automatic Rock Wool Conveying

Glostar’s high-quality steel coils and insulation materials are carefully selected and inspected; we can professionally bend these coils into various shapes, including complex configurations.

Pulverización de cola con alta atomización y aplicación precisa

Pulverización selectiva de pegamento

Glostar employs a high-atomization, targeted adhesive spraying process that achieves 99% surface coverage. We exclusively use adhesives from renowned international brands—such as Henkel (Germany) and Huntsman (USA)—to effectively enhance the bond strength between the core material and the facing panels, thereby ensuring the sandwich panel’s flatness and consistent quality.

Laminado de doble vía a alta temperatura​

High-temperature Dual-track Lamination

The metal facings and core material are bonded under double-belt pressure, and the adhesive is allowed to fully react and cure at a constant temperature of 55°C to ensure bond strength.

Corte del producto acabado​

Finished Product Cutting

Glostar offers sandwich panel cutting services, allowing for cutting to various dimensions. Backed by a professional engineering team and skilled machine operators, we can cut panels to your specific size requirements. Cut to the length specified by the customer (e.g., a tolerance of ±5mm is permitted for L ≤ 3000mm), ensuring the cut edges are straight and free of burrs.
Paletización del producto terminado​

Finished Product Palletizing

The finished sandwich panels are automatically stacked by world-class automatic palletizers to ensure neat storage and ease of handling.

Strict Quality Inspection

Control de calidad

Glostar conducts testing in accordance with the national standard GB/T 23932-2025, covering aspects such as appearance quality, dimensional deviation, bond strength (≥0.10 MPa for rock wool), and flexural load-bearing capacity (≥0.5 kN/m² at a deflection of L/200).
Envasado automático

Automatic Packaging

After passing inspection, the finished boards are moisture-proofly packaged, labeled with details such as model, thickness, and production date, and placed in storage awaiting shipment. The sandwich panels are professionally packaged using an automatic wrapping machine to ensure protection during transport and delivery.
