To select and purchase good and reliable filter bag cage manufacturer, it is necessary to know about filter bag cage production process.

Filter bag cage is one of key parts of dust collector bag house. Production process is key factor of working performance of filter bag cages. Good production process will take good working performance for filter bag cages.

INDRO is using hard drawn steel wire, stainless steel wire to make filter bag cages.

Hard steel wire and stainless steel wire which are used in INDRO are with excellent strength and stiffness. INDRO is using professional filter bag cage high frequency welding machine to do welding fabrication once.

The filter bag cage production process is as followings: wire drawing, straightening and cutting, supporting ring, support ring welding, welding, wear skeleton tube, welding bottom, pickling, electroplating, drying. Because carbon steel wire or stainless steel wire has a lot of oil pollution, before use, pickling and phosphating should be carried out for decontamination and rust removal.

Immerse proceeded filter bag cage into oil removing tank for 15 minutes to remove the grease on the surface of filter bag cages.

Take filter bag cages out of oil removing tank, put filter bag cages into cleaning tank for soaking, this is to remove the deoiling agent.

Take the filter bag cages out of cleaning tank, put filter bag cages into rust removing tank for rust removing. This is to remove the metal oxide layer on the bag cage, so as to enhance the adsorbability.

Take the filter bag cages out of rust moving tank, put filter bag cages into phosphating bath for doing phosphating and enhacing the adhesion of the filter bag cage surface.

Put the proceeded filter bag cage into the oven for drying for 20 minutes, set the temperature of oven at 2100 degree C, this is to remove the moisture of filter bag cages and keep the filter bag cage dry.

After drying, do spray and coating of filter bag cages. The thickness of coating is 60-100micron.

Put the painted filter bag cages into oven, set the temperature at 2220 degree C, do baking for 120 minutes. Then keep temperature at 2220 degree C, do heating setting up for 30minutes. Making filter bag cage cool down, then filter bags cages are finished.

INDRO controls each process of filter bag cages production very strictly, so that our filter bags cages are with excellent working performance and longer using life.
