Polyurethane Continuous Sandwich Panel Production Line: Characteristics and Methods

The complete set of equipment for the polyurethane sandwich panel production line mainly consists of an uncoiling system, film covering and cutting system, forming machine system, steel plate preheating furnace, high-pressure foaming system, double conveyor system, double conveyor heating system, cutting system, horizontal cooling system, stacking system, packing system, etc. Among them, the forming machine system is its core equipment part. This article will detail the production method and characteristics of the polyurethane continuous sandwich panel production line.

Production Method of Polyurethane Continuous Sandwich Panel Production Line

There are basically two methods in the process of polyurethane sandwich panel manufacturing line, namely continuous production and discontinuous production. Currently, the continuous sandwich panel production line is suitable for enterprises with high output demands, while the discontinuous production process is suitable for special-shaped products that cannot be produced continuously or production volumes that do not justify investment in continuous equipment.

In the continuous production process, materials for making sandwich panels are processed at high speed. Polyurethane foam is continuously sprayed between the uniformly moving, already formed upper and lower surface materials, where a polymerization reaction occurs, generating various forms of polyurethane sandwich panels. Cutting of the completely formed sandwich panels is done according to the desired length, and the cutting process does not stop on the continuous sandwich panel production line, ensuring an efficient production rhythm.

The discontinuous process is different, with materials handled separately. This means that after the facing material is formed, it is cut to the required length, then assembled together into the laminating press where foam is injected between the facing materials, creating the predetermined shape of the polyurethane sandwich panels. This method is suitable for small batch production or products that need to be shaped specifically.

Characteristics of Polyurethane Continuous Sandwich Panel Production Line

Adjustable Width Wall Panels

The polyurethane continuous sandwich panel production line features adjustable width wall panels, which can adapt to different wall width requirements. This characteristic endows the production line with great flexibility, enabling adjustments according to customer needs to meet diverse market demands.

High Precision Wall Panel Frame

The adjustable wall panel frame employs a fully welded profile structure, with cantilever-designed roller shafts on both sides. The single-row bearing seat adopts a combined form to ensure the precision and rigidity of the bearing seat. The single-row bearing seat is installed on a ball guide rail, allowing easy adjustment of specifications by just adjusting the lead screw. This design ensures high precision and efficiency in wall panel production of polyurethane continuous sandwich panel production line.

High-Quality Carbon Steel Rollers

The rollers and roller shafts of the forming machine use high-quality carbon steel, treated with tempering and precision CNC machining, followed by hard chrome plating on the surface. The comprehensive structural performance is excellent, ensuring stable, flat, and normal forming of the panels. This not only enhances product quality but also extends the service life of the polyurethane continuous sandwich panel production line equipment.

Independent Bearing Seat Structure

The bearing seat of the roof panel forming machine adopts an independent square bar assembly structure, with a galvanized surface treatment. It is aesthetically pleasing, has good rigidity, and a reasonable structure. This design makes the equipment more stable during operation, ensuring a smooth production process of polyurethane continuous sandwich panel production line.

High-Quality Transmission Components

The main transmission reduction motor and other reduction motors and key parts, components are all produced using equipment from well-known domestic and foreign companies, effectively ensuring the overall performance of the equipment. This not only improves production efficiency of polyurethane continuous sandwich panel production line but also ensures the reliability and durability of the equipment.

The polyurethane continuous sandwich panel production line, by introducing advanced production equipment and processes, possesses high efficiency, flexibility, and high-quality production capabilities. Its unique production method and outstanding equipment characteristics make polyurethane sandwich panels have broad application prospects in the cold chain industry. In the future, with continuous technological progress, the polyurethane continuous sandwich panel production line will continue to provide strong support for industrial development.
