Perforated Media
Perforated plates are used in a number of different applications for a variety of reasons. Perforation will be obtained by punching.
Used mostly as a screen, filter, shield, and guard, perforated materials can control the passage of air, liquid, light, solids, heat, electromagnetic waves, and sound waves. Supplied either fully perforated or with margins and/or blank areas, perforated sheet can be produced to meet your design and production requirements.
Available materials are among others: stainless steel types like 304, 316, 321 (see Stainless Steel Types), Inconel ™[*], Incoloy ™[*], Hastelloy ™[*], Monel ™[*], Duplex l™[*], Titanium, and non-metallic materials such as brass, copper, aluminium-bronze and synthetic materials. Averinox's specialities are critical perforation patterns, particular perforated areas and shapes on stainless steel material: very close perforations and hole diameters, equal, and in some instances even smaller than the plate thickness.

Perforation can also be obtained by drilling and/or milling. Using this special method, hole sections can be step-drilled, cylindrical and conical. Hole diameters may vary from 0.8 to 12 mm. Plate thickness amount to 20 mm. Many materials and alloys are possible. Specific surfaces can be obtained by among others sand-blasting or polishing.
This type of perforation is mainly used in the food industry, pulp & paper industry and chemical industry in for example the process of dewatering slurries.
Typical perforation patterns can be found at: Perforation Patterns.
