The production process of this decorative material

To introduce the production process of PU cultural stone, aimed at helping readers better understand

The production process of PU cultural stone is mainly divided into material preparation, mold production, material gluing, molding, dressing, coating, drying, inspection, packaging and other links.

The first is material preparation. The production of PU cultural stone mainly uses polyurethane materials, which are usually divided into two types: polyester type and polyether type. Polyester type has the characteristics of good weather resistance and high strength, suitable for outdoor decoration; Polyether type is flexible and resistant to extreme temperature, which is suitable for interior decoration. According to the needs of the product, choose different types of PU materials.

The next step is mold making. Mold is the key to making PU cultural stone, and a good mold can improve the quality and appearance of the product. Molds are usually made of silicone material, and are made according to design drawings and size requirements. The production of molds requires craftsmen to have rich experience and skills, and can accurately restore the required pattern and texture.

Then there is the material gluing. The prepared PU material is put into the gluing machine, and the PU material is injected into the mold by mechanical action. The glue dispenser can evenly inject the material into the mold, ensuring that the injected material can fill the entire mold, and there will be no defects such as bubbles.

The next step is molding. The mold with the injected material is placed on a press or shaking table for molding. Through the action of pressure or vibration, the material in the mold becomes stronger, ensuring the load-bearing capacity and durability of the product.

Then the trimming. Take the molded PU cultural stone out of the mold and repair it. In the process of dressing, the excess material needs to be removed, and the surface of the product is polished and decorated. The purpose of dressing is to make the surface of the product smooth and uniform, in line with the design requirements.

The next step is coating. The appearance of PU cultural stone can be adjusted by the choice of paint and coating process. According to the design requirements of the product, select the appropriate pigments and coatings, and then paint. Coating of coatings requires some skill and experience to coat quality and appearance.

Then the drying. After the coating is completed, the PU cultural stone needs to be dried. The purpose of drying is to allow the coating to dry and cure sufficiently to ensure the quality and durability of the product.

And then there’s the test. After drying, it is necessary to conduct quality inspection on PU cultural stone. The contents of inspection include appearance quality, dimensional accuracy, color consistency and so on. Only products that have passed the inspection can be packaged and sold in the next step.

After that is the packaging. The qualified PU cultural stone is packed, usually in cartons or wooden cases, to protect the integrity and safety of the product. In the process of packaging, the product can also be marked and batch management, to facilitate subsequent sales and installation.

In summary, the production process of PU cultural stone includes material preparation, mold making, material gluing, molding, dressing, coating, drying, inspection, packaging and other links. Each link requires skills and experience to ensure the quality and appearance of the product. Through reasonable process flow and fine production process, PU cultural stone can meet people’s high requirements for decorative materials, and provide more choices for modern architectural decoration.
