1. Molding: The molding of bathtubs, shower room chassis, back panels and other sanitary wares are usually formed by blister or composite board plastic plates. Because bathtubs and other products have a complex appearance and have a deep molding height, they are used by ordinary packaging materials. The materials and machinery are difficult to meet the process requirements, so the selection of appropriate plates and the selection of appropriate equipment are the basis for excellent sanitary ware molding.
2. Sheets: Plastic sheets for sanitary ware molding mainly use pure acrylic (chemical name methyl methacrylate) materials or A BS composite materials, as well as newly developed thermoplastic materials. The special acrylic sheet used for sanitary ware has excellent surface finish, its wear resistance is equivalent to aluminum, it is not easy to scratch, and it is easy to clean, and if accidental scratches occur on the surface, just use polishing agent, you can quickly and easily repair and restore.
3. Mold: In actual production, first design and process the blister molding mold according to the design drawings or actual samples of sanitary ware molding. Plastic molding molds generally use aluminum alloy or resin molds. Aluminum alloy molds have long service life, good process characteristics, and high surface finish. However, due to the high cost and long processing cycle, the application of conventional sanitary ware products is subject to certain restrictions.
4. Vacuum forming: heat the cut sheet as required in the furnace of the blister forming machine to soften the acrylic sheet, the general temperature is 180-220 degrees, and the composite sheet is generally 140-190 degrees) The softened sheet is mechanically pressed in On the mold, under the condition of in-mold sealing, through compressed air or vacuum blowing and suction, the sheet is thermally stretched and deformed and adsorbed on the mold wall. The cooling fan is started according to the time to make the sheet hard and formed, and then demolded. The product is taken out.
