Flow Chart of Polyurethane
The production starts with material preparation through unwinding and film application, followed by pressing to achieve the desired shape. Subsequently, the material undergoes spraying, preheating, and foaming stages to develop its characteristic polyurethane structure. The process continues with precise guidance and cutting to specific dimensions, after which the material is cooled to ensure structural stability. The final steps involve unloading the finished product and packaging it for distribution, completing the efficient and controlled production cycle.
Our Factory
The various production lines within the factory work closely together, the distance between parts and components from one workshop to another is short, and the material flow is fast, which reduces the logistics cost of the production process and avoids additional costs caused by multiple loading and unloading.
