stainless steel perforated sheet Pulse perforation for Bar soundproof panel
Product decribe
201 Stainless steel is generally referred to as 201 stainless steel and acid resistant steel.201 Stainless steel is
atmospheric, steam and water and other weak medium corrosion of steel, and acid-resistant steel is acid, alkali,
salt and other chemical corrosion of corrosive medium of steel.
Stainless steel perforated plate is refers to the plate material with sound-absorbing noise reduction effect is also
known as sound-absorbing decorative materials, mainly used in movie theaters, concert halls, museums, exhibition
halls, libraries, galleries, auction interrogation room, hall, gymnasium, hall, multi-function hall, hotel lobby, hospitals,
shopping malls, schools, piano room, meeting room, studio, recording studio, KTV rooms, bars, industrial workshop,
engine room, home to fall on the acoustic environment demand is higher and the site of high-grade decoration.
Perforation method
1.blasting perforation
The working principle of blasting perforation is that the material is irradiated by continuous laser to form a pit in the
center, and then the molten material is quickly removed by the oxygen flow coaxial with the laser beam to form a hole.
The size of the hole is related to the thickness of the plate. Blasting and perforating of the thicker plate can only be
used on the scrap.
2.pulse perforation
The principle of pulse perforation is to melt or vaporize a small amount of material with the pulse laser of peak power,
usually using air or nitrogen as auxiliary gas.Each pulse laser is progressively penetrated, and once the perforation is
complete, the auxiliary gas is replaced with oxygen for cutting.

Surface Treatment and characteristic
| Surface finish | Characteristics and application |
| NO.2B | The surface brightness and flatness of no2B is better than no2D. then through a special surface treatment to improve its mechanical properties,No2B could nearly satisfy compreh ensive uses. |
| NO.1 | The surface is finished by heat treatment and pickling or processes corresponding thereto after hot rolling. |
| NO.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria,but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150#320 on the NO.4 finish and has continuous streaks,mainly used as buildingsornaments elevators,door of building,frontal plate etc. |
| BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror,kitchen apparatus,ornament etc. |
| 8K | The product have excellent brightness and prefer reflexivity can to be the mirror. |
The drawing process is very particular in the application of stainless steel, and the application and process are
required. Under normal circumstances, it is necessary to repair and restore the wire drawing process equipment
to produce the final effect, and the overall drawing effect.
The surface of the cylinder can only be applied to the lathe or grinder. It only requires surface treatment. It can
be clamped with special abrasives and then the upper lathe is polished with sandpaper and cloth strip. If the
precision and surface roughness are high, the grinding machine is required. Polished.
When the surface is drawn, the raw material sheet is generally treated only. After the surface of the original
board is made of NO.4 (snowflake) or HL (brushed), the finished product is processed (die, deep drawing, etc.).
After the general processing method, the finished product can retain the surface effect of the original board.
Straight oil: It should mean oil straight wire, drawing after oil grinding, the surface of the ink is brighter after the
ink, and then a layer of wire drawing, which is a type of frosting, also belongs to the surface treatment, now has
a full roll of ink drawn Compared with ordinary wire drawing, the oil-grinding straight wire has the advantages of
clear brushed texture, neat texture, good gloss and excellent overall effect, and is widely used in elevator
ecoration and other equipment with high surface requirements.
