The specifications and dimensions of special-shaped acrylic sheets break through the limitations of conventional sheets and have highly customized features:
Thickness: The thickness range covers 1mm-100mm and can be flexibly selected according to the load-bearing, protective, and other requirements of the irregular structure. Small shaped decorative pieces can be selected with a thickness of 1mm-5mm, while large shaped display props can be selected with thick plates ranging from 16mm-100mm to ensure structural stability.
Shape and size: This is the core characteristic of special-shaped acrylic sheets, which can be customized into circular, elliptical, triangular, polygonal, curved, wavy, and various irregular artistic shapes. In terms of size, it is not constrained by the standard board size, and can be accurately produced according to the design drawings for irregular markings as small as a few centimeters and large irregular decorative parts as large as several meters. For example, circular shaped panels with a diameter of 50cm can be customized as desktop decorations, and curved shaped panels with a length of 3 meters and a height of 2 meters can also be made as exhibition hall background walls.
3. Performance characteristics
In addition to possessing the performance of conventional acrylic sheets, special-shaped acrylic sheets still maintain excellent performance under special shapes:
Transparency: Even with complex irregular structures, the transparency is still excellent, and the light passes through softly and naturally. For example, shaped lampshades can evenly distribute light and create unique light and shadow effects.
Weather resistance: It can work stably in the temperature range of -40 ℃ to 80 ℃, resist the erosion of natural environment, and is not easily cracked or deformed due to temperature changes or wind and rain erosion. Its service life can reach 5-10 years and is suitable for outdoor shaped billboards and other scenarios.
Mechanical performance: It has a certain degree of hardness and toughness, with better impact resistance than glass. It can withstand certain external forces in irregular structures, and even if accidentally damaged, the fragments will not be too sharp, with high safety. At the same time, the surface can be polished and polished to enhance the texture of the irregular parts.
Processing adaptability: Despite its unique shape, it still maintains good processing performance and can achieve complex shaped designs through various processes, meeting the creative needs of designers.
Chemical stability: It has a certain resistance to general acids, bases, and organic solvents, and is not easily corroded in daily use, ensuring the stability of the appearance and performance of the shaped acrylic board.
4. Color Types
The colors of irregular acrylic sheets are rich and diverse, which can be matched with irregular shapes to enhance visual effects:
Transparent shaped acrylic board: with the best transparency, it is suitable for making shaped parts that need to display internal structure or lighting effects, such as shaped fish tanks, transparent shaped display stands, etc.
Colorful shaped
Acrylic sheet: covering solid colors such as red, yellow, blue, green, as well as gradient colors, pearl colors, etc. Solid color irregular plates can be used to make brightly colored irregular signs and signboards; Gradient and pearl shaped panels are more artistic and suitable for high-end shaped decorations, such as shaped screens and artistic ornaments.
Matte shaped acrylic board: The surface is treated with a frosted finish, making it transparent and opaque, which can protect privacy and create a hazy beauty. It is suitable for shaped partitions, shaped lampshades, etc.
2、 Process Description
1. Processing technology
The processing technology of special-shaped acrylic sheets is more complex and refined, requiring the combination of multiple processes to achieve special shapes:
Cutting process: Laser cutting is the main method, which has high precision and can accurately cut various complex irregular contours. The incision is smooth and flat, reducing subsequent polishing processes. For some large and simple irregular parts, mechanical cutting can also be used in conjunction with later trimming.
Carving process: Carving on the surface or edge of irregular acrylic sheets can form patterns, text, or textures, enhancing the decorative value of irregular parts. After carving, the surface is polished and polished to make it smooth and delicate, suitable for personalized irregular logos, artworks, etc.
Bending process: This is the key process for making irregular structures such as curved and wavy shapes. Soften the acrylic sheet by heating, and then bend and shape it according to the shape of the special-shaped mold. Hot air heating or water bath heating are commonly used to ensure accurate bending angle and curvature, and stable structure after shaping.
Splicing process: For oversized or overly complex shaped acrylic sheets, splicing process is required. Use specialized acrylic adhesive to bond multiple components together, ensuring that the joints are flat, firm, without bubbles or gaps, and the overall performance of the assembled special-shaped parts is not affected.
Polishing process: After cutting, carving and other processes, the edges and surfaces of the irregular acrylic board need to be polished. Suitable polishing methods such as cloth wheel polishing, flame polishing, diamond polishing, etc. can be used to select the appropriate polishing method according to the shape of the irregular part, making the surface of the irregular part smooth and transparent, and enhancing the overall texture.
2. Production process
Design and Modeling: Based on customer needs and application scenarios, conduct professional design, draw detailed drawings of irregular structures, and construct three-dimensional models through 3D modeling software to ensure the rationality and feasibility of irregular shapes, while considering the adaptability of processing technology.
Material selection: Based on design requirements, select acrylic sheets with appropriate thickness, color, and performance to ensure that the material quality meets standards and can meet the needs of special-shaped processing and use.
Cutting and cutting: According to the design drawings and 3D models, the acrylic sheet is preliminarily cut using laser cutting or mechanical cutting methods to obtain rough blanks for shaped parts.
Special shaped forming processing: Based on the characteristics of the special shaped structure, bending, carving and other processing are carried out. Strictly control the heating temperature and time during bending to ensure bending accuracy; Accurately operate according to the design pattern during carving.
Splicing and assembly (if necessary): For the special-shaped parts that need to be spliced, use special glue for bonding and assembly to ensure that each component is connected firmly, smoothly, and meets the design requirements.
