Continuous PU PIR sandwich panel production line is one of the most important representative products of Sinowa. We mainly provide various leading highly integrated and automatic continuous PU sandwich panel line and our customers come from each corner all over the world. With rich production experience and technical concept of continuous innovation and improvement, we have various comprehensive indexes of our production lines at the highest level in the field.

Sinowa focuses on the R&D and innovation of high-end, high-efficiency sandwich panel production lines. Our polyurethane sandwich panel production line takes a comprehensive leading position in the industry in terms of operational efficiency, automatic control level, HMI human-machine interaction, environmental protection and energy consumption indicators. We have achieved subversive breakthroughs in key technical fields, effectively optimizing the overall cost performance of the production line and bringing intuitive, user-friendly operation experience for global customers. Adopting advanced system integration and bus control technology, our polyurethane sandwich panel line realizes full-process automatic integrated linkage control, supporting stable and convenient remote interactive communication. With world-class comprehensive performance, it stands out as a top-tier high-performance sandwich panel production solution in the current market.

Endowed with ultra-high production compatibility, our continuous PU/PIR and rock wool sandwich panel production line fully meets the diversified production needs of global manufacturers. Adopting a modular overall design, all sandwich panel equipment components support free integration and flexible combination. Through simple configuration switching and parameter adjustment, the polyurethane sandwich panel manufacturing line can automatically and efficiently produce roof sandwich panels, wall sandwich panels, cold storage insulation panels and other mainstream products. It supports multiple core materials including polyurethane, PIR, rock wool and glass wool, covering mainstream insulation panel systems on the market. We provide personalized equipment configuration and targeted product design services according to customers’ production scales and product positioning, with a flexible pricing system to create exclusive cost-effective solutions for every client.

Equipped with a high-level centralized linkage control system, our polyurethane sandwich panel production machinery integrates all core control points into a central control platform, realizing full-line parameter linkage, real-time fault self-diagnosis and precise stroke distance control. The unified process control console manages all mechanical movements of the entire line, paired with efficient remote communication functions, which greatly improves the overall automation level of production. This intelligent control mode completely avoids the defects of scattered control and low coordination efficiency of traditional equipment, effectively reducing manual operation links, lowering labor input and human resource loss for customers, and helping enterprises realize intelligent and unmanned production workshops.

The whole PU sandwich panel machine adopts standardized modular design, which optimizes the structural layout of the production line and reduces the number of matching parts. This design greatly reduces equipment failure probability and daily maintenance costs, ensuring long-term stable and reliable precision operation of the equipment. All key parts are precisely processed by machining centers, with zero manual splicing errors. After strict inspection and warehousing, the parts are assembled in a standardized process, which fundamentally eliminates the impact of human factors on product quality. Modular assembly not only significantly improves equipment production efficiency and delivery speed, but also realizes high interchangeability of parts, bringing great convenience for later equipment maintenance, upgrade and replacement.

Supported by more than 40 independent innovative patented technologies, our PU sandwich panel assembly line has unique structural advantages and leading comprehensive performance in the industry. Different from traditional equipment, the main engine adopts a precision servo hoisting structure and cancels the hydraulic system. This innovative design realizes flexible and accurate adjustment of board thickness, allowing customers to quickly switch and set product thickness according to production demands. It completely solves the common pain points of hydraulic equipment such as troublesome debugging, oil leakage and frequent maintenance, greatly reducing equipment failure rate and later maintenance workload, and improving the continuity and stability of industrial production.

Our PU sandwich panel production line adopts top-level energy-saving and environmental protection design, realizing 24-hour uninterrupted all-weather stable production and helping customers save a large amount of operating costs. The independent thermal insulation room structure and fully sealed internal thermal insulation design optimize the equipment’s thermal insulation performance to the greatest extent. The high-power and low-consumption operation structure ensures fast equipment response while controlling energy consumption at an ultra-low level. The insulation system can quickly heat up from room temperature above 5℃ to production standard temperature within one hour, and the overall energy consumption is only 40% of similar products in the market. The efficient energy-saving and environmental protection configuration creates higher economic benefits for customers while meeting global environmental production standards.
