PU Continuous Sandwich Panel Production Line

PU sandwich panel is a kind of sandwich panel made of polyurethane (Polyurethane) foam material, also known as polyurethane sandwich panel. It consists of a layer of polyurethane foam sandwiched between two layers of metal sheets. Polyurethane foam material has good thermal insulation, heat insulation and sound absorption properties, so PU sandwich panel has excellent thermal insulation effect.

It is commonly used in the external walls of buildings, roofs, cold storage, workshops and other places of thermal insulation and fire retardant materials.

In order to meet the needs of factories in different industries for the production of PU laminates, KINGREAL CEILING MACHINERY specializes in the production of PU Continuous Sandwich Panel Production Line, which can realize efficient, continuous and auto production, improve production efficiency and product quality.

At the same time, the production line can also be customized according to customers’ needs, producing sandwich panels with different specifications, thicknesses and colors.

1. Main Roll Forming Machine

The PU Continuous Sandwich Panel Production Line Roll Forming System incorporates a double head roll forming machine specifically designed for the production of upper layer profiles. This machine is equipped with two sets of forming rollers, ensuring efficient and precise shaping of the profiles.

Additionally, the upper roll forming machine is complemented by a guiding system, a transmission system, and a sturdy frame, all of which contribute to its seamless operation.

2. PU Foaming System

The accessories for the foaming system consist of the sheet transmission conveyor, adhesive tape sealing device, and sponge sealing device.

3. Double Belts System

The Double Belts System (DBL) serves as an effective solution to address the issue of foaming expansibility by ensuring its solidity and determining the panel thickness and production speed. The side belt, on the other hand, plays a crucial role in overcoming horizontal expansion, determining the panel width, and providing guidance to the panels.

High degree of automation: PU sandwich panel molding machine adopts PLC control system, which can realize automatic production, reduce manual operation and improve production efficiency.

High molding precision: the molding machine has precise temperature control and pressure control system, which can ensure the molding precision and stable quality of sandwich panel.

1. The production line adopts hot air circulation heating furnace to ensure the stability of PU material foaming and curing within the control range, ensuring high quality of the laminated panels;

2. adopting high pressure foaming system, even foaming, accurate measurement and high stability, environmentally friendly process for composite production.

PU sandwich panels are widely used in many fields, mainly including:

Construction industry: used for walls and roofs of industrial plants, warehouses, cold storage and commercial buildings, providing excellent thermal insulation and structural strength.

Cold chain logistics: used in refrigeration and freezing equipment to ensure temperature control of perishable items such as food and medicine.

Transportation: used in containers, refrigerated trucks and transportation equipment to provide thermal insulation and ensure the quality of goods during transportation.

Indoor decoration: used in interior walls and ceilings of places such as shopping malls, supermarkets and exhibition halls to enhance aesthetics and functionality.

Clean room: used in the walls and ceilings of clean rooms in the pharmaceutical, electronics and food industries to meet the requirements of special environments.

The main function of sandwich panels is to provide excellent thermal insulation, heat insulation and sound insulation. At the same time, they have the advantages of light weight, high strength, easy installation and strong durability, making them perform well in a variety of applications.
