Perforated Metal for Test Sieves

The perforated metal can be used for making test sieves, which are mainly used in screening and filtering granule and powder material in the industries of food,chemical,pharmaceutical,laboratory,building,abrasive,metallurgy,etc.

These perforated plate sieves are constructed through a process of stamping holes in a sheet of thin metal.

The size and shape of the holes are controlled by a die.

These dies can be produced with a variety of shapes to deal with special grading needs for materials such as coffee and grain.

They are normally used for openings greater than 2.0mm in size.
