Stone plastic floor production process
The production process begins with precise automated measurement of raw materials based on their specific ratios. These ingredients then undergo hot mixing in a high-speed mixer at a temperature of 125°C. This step ensures thorough blending of all components while eliminating any residual moisture. Following this, the mixture is transferred to a cold mixing stage where it is cooled down to around 55°C. This cooling phase not only prevents clumping and discoloration but also helps maintain optimal texture before further processing.
Next, the cooled material is fed into a twin-screw extruder for heating and shaping. Afterward, it moves through a sheet die for extrusion and onto a four-roll calendering machine that adjusts the thickness of the base material. Subsequently, decorative films are applied, followed by adding a wear-resistant layer. The product then undergoes cooling and cutting processes to achieve the desired dimensions.
In the third stage, the surface undergoes UV treatment for enhanced durability and aesthetics. This is followed by tempering, which involves immersing the material in tempered hot water ranging from 80 to 120°C, then quickly cooling it with water at approximately 10°C.
Finally, the finished product goes through cutting and slotting operations, including grooving, trimming, and chamfering. Each piece is carefully inspected for quality assurance before being packaged for distribution. Throughout these steps, every detail is meticulously controlled to ensure consistency and excellence in the final product.
