Punching aluminum veneer has better decorative effect, which is easy to ventilate and reduce the positive and negative wind pressure coefficient of curtain wall system. After installation, it is combined with LED color lamp light source to present various decorative mood through various hole patterns. Punching aluminum veneer is also called metal perforated aluminum plate. We use high-quality metal materials,
Common hole patterns such as round hole, square hole, elliptical hole, diamond hole, five pointed star hole, long waist hole, etc., can also be customized according to customer requirements, such as trademark logo graphics. The processing method is generally through CNC machine tools for stamping, or die punching. According to the hole type, hole diameter and edge distance in the CAD drawing, G code is programmed in the CNC computer to automatically and frequently process according to the requirements. There are also some CNC engraving machine for carving holes, and this process is only suitable for large circular aperture. Because the commonly used tool radius of engraving machine is r3mm, the processing of square hole or corner part is not perfect. Even a square hole will have four rounded corners.
Selection of aperture:
For the selection of punching hole diameter of aluminum veneer, it depends on the place where the material is used. For indoor ceiling gusset plate, the hole diameter is Φ 0.5 ~ 5.0 mm, for indoor wall diameter is Φ 10 ~ 20 mm, for outdoor wall diameter is Φ 20 ~ 50 mm, Φ 60 ~ 100 mm, Φ 100 ~ 200 mm, etc. Specific to see the overall area of aluminum veneer curtain wall, as well as field of vision space. It is also common to use 10-20 cm large holes for curtain walls of large projects. Conventional aperture: Φ 0.5 ~ 5.0 mm, Φ 10 ~ 20 mm, Φ 20 ~ 50 mm, Φ 60 ~ 100 mm, Φ 100 ~ 200 mm, etc. More hole sizes can be customized.
Advantages of punching aluminum veneer:
After punching, the aluminum veneer can relieve the sense of claustrophobia and depression caused by the closed space, making the product have a vague and open space vision. For the aluminum veneer on the facade, the positive and negative wind pressure can be significantly reduced after punching, and the safety factor of the aluminum veneer curtain wall system can be increased.
The perforated aluminum veneer can be filled with sound-absorbing materials on the back of the board to achieve sound absorption effect. The sound waves can not be refracted out after entering the sound insulation materials, so as to eliminate the noise. The punching sound-absorbing board is commonly used in the interior ceiling and wall sound insulation decoration with sound absorption and sound insulation requirements in meeting rooms, singing halls, cinemas, KTV, etc.
After installation, combined with background lighting, the overall appearance is elegant, fireproof and moisture-proof. The construction is simple and durable,
Pass arrangement of aluminum veneer:
Generally, the common arrangement of punching holes is: straight row holes, plum blossom holes (oblique rows), more commonly used, and the recently popular random distribution of large and small holes in the sky star hole, and the size gradually changing hole type, as well as the combination of large and small holes to punch out the pattern outline of the art hole.
Straight row of holes is the most simple, using a crisscross way, covering the whole board. Oblique row hole is left and right oblique row, three holes into a triangle, four holes into a diamond, seven holes for plum shaped. However, the random distribution of stars in the sky is not regular. As for the hole patterns of art patterns, customers need to provide high-definition pictures, such as simple sketch landscape drawings, portraits, company image logo, etc., which can be shown through the outline of large and small hole patterns and light source projection.
