As one professional filter bag cages manufacturer, Shanghai Indro Industry Co., Ltd has been manufacturing and exporting different filter bag cages to many countries of the world, such as USA, Canada, Spain, Mexico, Italy, Russia, Saudi Arabia, Singapore, Malaysia, Korea and so on.

According to our experiences, there are following package method or solutions of filter bag cages:

Nude package of filter bag cage: This is one most economic package. When your filter bag cages quantity is large, and you are booking full container for shipment, this package is suitable. Better only load your filter bag cages in one container. Normally, you shall send containers to your filter bag cage factory to load filter bag cages on site.

Basic package of filter bag cages: Use woven bag or clear bag to package filter bag cages. One piece of filter bag cage is put into one woven bag or clear bag.

This is also one economic package. But compared with nude package, package cost shall be higher by approx USD1 per cage. This package is suitable for small quantity of filter bag cages with LCL shipment. Then means your cages need to be loaded in one container with other goods together. 

Bundles package of filter bag cages: 5-8 pieces of filter bag cages are one bundle.

Then load one bundle in one clear bag or woven bag. Use belts or ropes to fasten in the middle of bundles. If necessary, use cartoon box at the both ends of each bundle.

If using cartoon box at both ends, this package is becoming one high class filter bag cages package, so its cost is high. It is suitable for LCL shipment.

Normal metal frame package of filter bag cages: Design and custom make special metal frame according to exact diameter and length of filter bag cages. There are several supporting bars at the bottom of metal frames, blocking bars at sides. If necessary, add support board at the bottom of frame depends on requirement. This package is also not economic. For large quantity filter bag cages of LCL or FCL shipment, this package is suitable.

Upgrade metal frame package of filter bag cages: add wheels into metal frames. And two wheels are with brake function. This is for easy moving of large quantity filter bag cages. And metal frames can be reused. This package of filter bag cages is with high cost as well.

Carriage type package of filter bag cages: Add boards onto metal frame at bottom and sides. This is highest class package of filter bag cages. And its cost is highest.

Overall, different filter bag cages package affect filter bag cages price very much, and also different filter bag cages package affect the shipping space, such as the container number, so they affect the filter bag cages shipping cost as well. When you buy or purchase filter bag cages, you shall consider the quantity of filter bag cages, shipment type and your budget to select most suitable package of filter bag cages.

Industrial cages/ Dust Collection Filter Bag Cages | Shanghai INDRO

Filter bag cages are one of important parts for dust collector bag house system.

Cages support the shape of dust collector filter bags and prevent them from collapsing on themselves.  Just like the bags, cages come in many shapes, sizes, and configurations.

INDRO manufactures filter bag cages to fit nearly any dust collector.  Our cages can be made for high temperature, high moisture, acidic or other environments.  Whatever your application, we can make a cage to meet your needs.

About production standard of filter bag cages

Filter bag cages require the vertical wire and supporting rings are uniform distributed and with enough strength and stiffness, so that can be withstand the pressure during dust cleaning of filter bags. And also avoid the damage and deformation caused by collision and impact during delivery and installation of filter bag cages.

All the welding of filter bag cages must be strong. Loose welding and rosin welding joints are not allowed.

The surface of filter bag cages which will be in touch of filter bags shall be smooth, welding scars, sags and rag are not allowed.

The tension spring type of filter bag cage should have enough ring number and elasticity, and the spacing should be uniform after pulling out.

The surface of the filter bag cages must be treated with corrosion protection and galvanized according to different needs. Spraying or painting, such as for high temperature and corrosion protection, shall meet the requirement of using temperature.

Dust filter bag cage material Q235 or 20 steel wire, wire diameter 3mm-4mm, supporting ring distance 150cm--250cm.

The verticality of the dust bag cage is 6M plus or minus 1mm.

The dust bag cages include one complete cage, segmented cage such two section or three sections.

Tips of filter bag cage production process

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.
