Take the molded PU cultural stone out of the mold and trim it. During the trimming process, it is necessary to remove excess material and polish and modify the surface of the product. The purpose of trimming is to make the surface of the product smooth and uniform, meeting the design requirements.
The appearance of PU culture stone can be adjusted by spraying process. According to the design requirements of the product, choose the appropriate paint and then spray it. The spraying of paint requires skills and experience to ensure the quality and appearance of the coating. Our coloring process includes primer, effect layer and outer weather-resistant topcoat. The PU stone made in this way is richer in color, more artistic and beautiful. Our production process is complicated, sometimes even up to 5 layers or more.
After the coloring is completed, the PU culture stone needs to be dried. The purpose of drying is to allow the paint to fully dry and solidify to ensure the quality and durability of the product.
After the drying is completed, the PU culture stone needs to be inspected for quality. The inspection content includes appearance quality, dimensional accuracy, color consistency and other aspects. Only products that have passed the inspection can be packaged and sold in the next step.
The qualified PU culture stone is packaged, usually in cartons or wooden boxes to protect the integrity and safety of the product. During the packaging process, the product can also be marked and batch managed to facilitate subsequent sales and installation.
