Stone plastic floor production process
The production process begins with precise measurement of raw materials based on their specific ratios. This mixture is then fed into a high-speed mixer where it undergoes hot blending at a temperature of 125°C. This step ensures thorough mixing of all components while also eliminating any moisture present in the materials. Following this, the blended mixture is transferred to a cold mixer to cool down to around 55°C. Cooling at this stage prevents clumping and discoloration, ensuring the material remains consistent and stable.
Next, the cooled material is extruded using a twin-screw extruder which heats and shapes it further before sending it through a sheet die. Once extruded, the sheet passes through a four-roll calendering system that adjusts its thickness. Afterward, a colored film is applied followed by a wear-resistant layer. The product then undergoes a cooling phase and is cut into desired sizes.
For the third stage, the surface undergoes UV treatment for additional hardening. Subsequently, the product is tempered using hot water at temperatures between 80-120°C, followed by cooling with cold water at approximately 10°C. This tempering process enhances durability and stability.
Finally, the finished product moves on to the finishing stages. These include cutting, grooving, trimming, and chamfering to achieve the perfect shape. Each piece is then inspected for quality assurance before being packaged. Throughout these steps, attention to detail ensures that every product meets high standards of quality and performance.
