The Fire damper frame manufacture auto line can fabricate two kinds of frames, newly designed hand fold integrated frame and TDF corner fastened frame.

Smoke exhaust outlet also called positive pressure air supply outlet . The frame auto line consists with decoiler, straightening , punching , roll forming and folding . Patented design which Comifo has its copyright.

Damper blade auto line makes manufacture for damper blade easier! Combine with a decoiler, cutting and punching unit, an auto line can be provided for three different sizes of blades with different coil width.

Comifo is the first one and also the unique one who makes this fastening platform. It consists of fire damper corner fastening, seam closing fastening, hanging double fastening and hanging single fastening.

The auto line manufactures the support bar for the dampers automatically with decoiler, roll forming , punching and cutting.

Used in manufacture applications to cut sheet metal up to 1500*3100mm and 6mm thick for Galvanized Steel, the Compa 3100 meets the requirement for not only efficient and productive, but also highly cost-effective.

It enjoys the advantages with Compa 3100, and provides the working platform for 1500*5100mm and maximum 6mm thick depend on different materials.

This 8/9-station lock former offers 6 forming positions, pittsburgh and auxiliary double seam(ACME),right angle flange, drive cleat (size of 25mm) with slitter, as well as top mounted power flanger.

RF-12M is featured of flat “S” cleat rollers. It has pittsburgh, double seam (ACME), as well as drive cleat (size of 28mm).

The Button Lock roll former comes with "male" tooling on one side and "female" on the opposing side. A fast, effective way. Rollforms Male & Female Button Lock in one machine,with the thickness range from 0.8mm to 1.2mm.

9-station machine which fabricate both male and female forms for reeves-type snap lock. Each lock is formed on flat sheets with no restriction on the diameter of the finished pipe. This type of lock is more air-tight with better seam.

The Button Lock roll former comes with "male" tooling on one side and "female" on the opposing side. A fast, effective way. Rollforms Male & Female Button Lock in one machine,with the thickness range from 0.4mm to 0.8mm.

It forms a shape that combines a conventional “S” cleat with a standing seam for greater strength and rigidity with a thickness of 22ga.

It shares common advantages with TDF flange well seal, free of jointing and rivet. GDF flange is integral with duct, with 4 bolts and special duct corner and clamp.

The machine makes one side TDF flange and the forms Clip. 16 forming stations produce an intefral flange while another 9 forming stations produce clip. With compact design, this machine can be taken to construction site easily.

TTF/LT mate flange has well seal,strong and durable joint structure. Therefore it is specially suitable for producing a duct with large sectional area.

Spiral tube forming machine processes round duct of maximum diameter up to 1400mm. With strong seal, flexible, It can be adjusted to make ducts with different diameters by changing different forming strips.

It processes round duct of maximum diameter up to 1600mm. it is easy to change the diameter for different duct size by changing different forming heads. Hydraulic roll cutting provides no burrs, sparks or noises.

The latest design in seaming technology is now available. At the Pittsburgh joint, the individual seams are called Pittsburgh seam(pittsburgh lock) and standing seam(right angle flange).

This machine is suitable for mate flange duct and C cleat joint duct manufacture. Combined with Comifo duct manufacture compact line III, hand cleat folder,production efficiency can be greatly improved.

It saves installation labor , decreases leakage and eliminates twists. Regarding both end corner inserter , the max height adjustable up to 1600mm section.

COMIFO Elbow Maker is the special equipment for both connecting lock and seaming when processing on metal plate round pipe and round elbow.
