Mastering the Sandwich Panel Manufacturing Process: Efficiency and Precision With Jinggong Technology

What Is the Sandwich Panel Manufacturing Process?

The sandwich panel manufacturing process is a highly precise and automated production method that combines different layers of materials to form lightweight, durable, and thermally efficient panels used in construction and industrial applications. A sandwich panel typically consists of two outer metal sheets bonded to an insulating core made from materials such as polyurethane (PU), polyisocyanurate (PIR), rock wool, or expanded polystyrene (EPS). This structure provides superior mechanical strength, excellent insulation, and soundproofing properties. During the manufacturing process, raw materials are precisely fed, heated, pressed, and cut through an automated line, ensuring consistent quality across every panel. With the advancement of intelligent machinery, the sandwich panel manufacturing process has evolved into a highly efficient system that integrates coating, forming, laminating, and cutting into one seamless production flow.

The Core Stages of an Advanced Sandwich Panel Manufacturing Process

The sandwich panel manufacturing process begins with the preparation of coil steel for the outer layers, followed by surface treatment and preheating to ensure proper adhesion. The core material, whether PU, EPS, or rock wool, is then accurately metered and injected between the two steel sheets. The panel then enters a continuous laminating and heating section where bonding and curing occur under uniform pressure and temperature. After lamination, panels are cooled and trimmed to precise dimensions. Finally, cutting, stacking, and packaging are completed automatically, resulting in ready-to-install products. Each stage is carefully monitored to maintain consistency in thickness, bonding strength, and surface quality. Jinggong's advanced technology ensures that every panel produced through this process meets international standards for durability, fire resistance, and insulation efficiency.

How Does the Sandwich Panel Manufacturing Process Ensure Structural Excellence?

The sandwich panel manufacturing process plays a vital role in determining the structural integrity and thermal performance of building systems. Through precise temperature control and accurate chemical mixing, the core layer forms a dense, uniform structure that provides excellent compressive and shear strength. The outer metal sheets, typically galvanized or pre-painted steel, offer weather resistance and mechanical protection. The combination of these materials through advanced bonding technology results in panels that are strong yet lightweight. This makes them ideal for prefabricated buildings, cold storage facilities, and industrial enclosures. By maintaining a perfect balance between rigidity and flexibility, the sandwich panel manufacturing process ensures that the finished panels can withstand environmental stress, temperature fluctuations, and mechanical loads while retaining their structural integrity over long service periods.
