Insulation Sandwich Panel Production Line Manufacturer In China

Sinowa is a insulation sandwich panel production line manufacturer in china, the insulation sandwich panel production line is a specialized equipment system in the field of modern building materials manufacturing, representing the high-tech level of industrial production in construction. This type of production line uses highly automated processes to composite surface materials (such as color steel plates, aluminum foil, non-woven fabrics, etc.) with core insulation materials (such as polyurethane, rock wool, phenolic resins, etc.) into sandwich panels with excellent performance.

The insulation sandwich panel production line usually adopts a modular design concept, which can be flexibly configured to meet the production needs of different products. The Sinowa insulation sandwich panel machine can produce various products such as polyurethane double-sided color steel sandwich panels, polyurethane double-sided non-woven fabric/kraft paper/cement cloth insulation panels, composite edge sealing rock wool panels, and phenolic double-sided aluminum foil/non-woven soft surface layer panels. The design concept of "one machine for multiple uses" greatly improves the utilization and economy of equipment, enabling manufacturers to quickly respond to market changes and customer demands.

The progressiveness technology of insulation sandwich panel production line is mainly reflected in the level of automation control and production efficiency. At present, leading production lines have adopted system integration technology and bus control technology to achieve full automation of integrated and coordinated control of the entire production line, and have remote interactive communication functions. The optimized design of human-machine interface (HMI) makes operation more intuitive and convenient, while innovative designs in environmental protection and energy consumption make the production line in line with the current trend of green manufacturing development. It is worth mentioning that some high-end production lines have undergone disruptive design in key process areas, achieving excellent cost-effectiveness and user-friendly experience.

The basic process flow of insulation sandwich panel production line includes surface material unwinding, core material preparation, composite lamination, curing and shaping, cutting and trimming, etc. For chemical foam core materials such as polyurethane (PU), phenolic resin (PF), etc., precise raw material ratios, mixing, and infusion systems are also required. Different types of sandwich panels have differences in production processes, but modern production lines can quickly switch production modes through flexible module designs to meet the market demand for multiple varieties and small batches. For example, the same production line can produce various products such as roof sandwich panels, wall sandwich panels, and cold storage sandwich panels through simple adjustments. The internal core layer can be selected between different materials such as polyurethane, rock wool, and glass wool as needed.

The insulation sandwich panel production line is mainly divided into several categories based on the different core materials and production processes, including polyurethane (PU/PIR) sandwich panel production line, phenolic sandwich panel production line, rock wool sandwich panel production line, and composite sandwich wall panel production line. Each type of production line has its unique technical characteristics and applicable fields. Understanding these differences helps users choose the appropriate equipment according to their own needs.

The polyurethane (PU) and polyisocyanurate (PIR) sandwich panel production line is an important equipment in the modern construction industry, used to produce composite panels with excellent insulation performance. This kind of production line combines polyurethane or PIR foam core material with metal surface layer (usually color steel plate or stainless steel plate) through continuous foaming process to form building panels with high strength, lightweight and excellent thermal insulation performance. The polyurethane sandwich panel production line usually consists of a metal coil unwinding system, surface pretreatment equipment, forming unit, two-component polyurethane raw material high-pressure foaming system, composite press, curing area, cutting system, stacking device, and automation control system, etc., realizing a fully automated production process from raw materials to finished products.

Phenolic sandwich panel is a new type of building insulation material with phenolic resin as the core material. With its A1 level fire resistance, ultra-low thermal conductivity, and environmentally friendly and non-toxic characteristics, it has become the preferred solution to replace traditional materials such as EPS and rock wool. The phenolic sandwich panel production line adopts modular design and fully automatic control. The phenolic resin synthesis and foaming section supports precise proportioning of multi-component raw materials and pentane foaming technology; The upper and lower layers are compatible with various surface materials such as color steel, aluminum foil, non-woven fabric, etc; Temperature control accuracy ± 1 ℃, ensuring foam uniformity; PLC+bus technology enables full line linkage and remote monitoring.

The rock wool sandwich panel production line is a highly automated industrial equipment system specifically designed for producing building sandwich panels composed of metal panels and rock wool core materials. This production line integrates mechanical engineering, materials science, and automation control technology to efficiently and accurately manufacture building materials with excellent fire resistance, insulation, and sound insulation performance. The rock wool sandwich panel production line is a continuous production system that integrates multiple processes such as uncoiling, forming, laminating, cutting, and stacking. It mainly consists of two parts: a metal panel processing system and a rock wool core material processing system. This type of production line can be divided into two types according to the degree of automation: fully automatic and semi-automatic. According to the length requirements of the product, it can be divided into two specifications: large machines (for producing long boards) and small machines (for producing short boards).

Composite sandwich wall panels, as the mainstream choice in the modern construction industry, are gradually replacing traditional building materials due to their excellent properties such as lightweight, high strength, insulation, and sound insulation. As the core equipment for producing such new building materials, the technical level and automation level of the composite sandwich wall panel production line directly determine the product quality and production efficiency. The production line of composite sandwich wallboard is an automatic production system integrating raw material processing, molding and pressing, curing and drying, cutting and packaging. According to different product specifications and material formulas, the production line configuration may vary, but the core process flow is basically the same.
