Aluminum Punch Plate

Aluminum Punch Plates need to use high-strength aluminum alloys, like 6061-T6 with a yield strength of at least 240 MPa or 5052-H32 with an ultimate strength of 180 MPa, and the plate thickness tolerance is strictly controlled within the range of ± 0.5 mm. The punching process requires a hole diameter deviation of less than ±0.3 mm, hole distance error of no more than ±0.1 mm, and laser cutting to ensure that the edges of round, square or hexagonal holes are burr-free. The perforation rate needs to be precisely designed according to the function, usually maintaining 15% to 40% for decorative use, increasing to 40% to 70% for filtration scenarios, and optimizing to 20% to 35% for anechoic applications. All the perforations must be staggered at 60 degrees in order to enhance the stability of the structure, and the angle of the perforation wall and the plate surface should be at least 89 degrees to avoid the accumulation of dirt.

1.Architecture 

Aluminum punch plate has become an ideal choice for exterior wall decoration and interior ceiling due to its excellent structural adaptability and aesthetic performance.

When combined with high-performance PVDF coating, a dense fluorocarbon protective layer with a thickness of 60 microns is formed on the surface of the panel, which not only effectively reflects noise sound waves, but also realizes a noise reduction coefficient of more than 0.7 and significantly improves the acoustic environment of commercial spaces, transportation hubs and other places.

Its unique hole array design can attenuate the energy of medium and high frequency noise up to 15 decibels through acoustic wave diffraction principle, while maintaining more than 50% natural light transmission rate, perfectly balancing the functional and visual needs.

2.The industry

As a core component of filtration and screening systems, specialized manufacturers can customize diamond-shaped perforation solutions with pore sizes ranging from 5 to 20 mm, depending on the mineral properties.

This special hole pattern prevents the ore from jamming and, combined with the wear-resistant properties of the 5052-H32 aluminum alloy substrate, achieves a separation efficiency of 98% in iron ore screening.

For different material characteristics, gradient opening design is also available - φ15mm large holes are used at the front end to intercept coarse material, and φ8mm precision holes are configured at the back end for secondary screening, and the service life of the whole system is more than 3 times higher than that of the traditional wire mesh, which significantly reduces the maintenance cost.
