Brief Introduction,

Square Duct Forming “Line II” adopts modular Linear design, with several integrated flexible workstations.

Total length of the line is about 4mtrs.

Basic Equipments,

1. Electric uncoiler(two sets) driven by independent frequency controlled motor.

2. Multi-functional machine with capability of levelling,grooving,angle shearing and plate shearing

3. Computer controlling system and softwares.

4. Electric box

Characteristics,

1. Optimized linear structure makes the whole line beautiful in appearance and fast in production

2. 11 rollers are equipped for levelling to make sure plate gets even.

3. This machine is a material-saving facility with only less than 20mm wasted plates per roll.

4. Highly advanced servo system controls the whole production line very well so the products produced are perfect in appearance and precise in size.

5. One man is capable to handle the whole line

6. Workpieces counting system to count for one-day and accumulated quantities.

Duplex TDF Flange Forming Machine

To overcome the normal TDF flange forming machine’s disadvantage

that only one end of the plate can be operated to form flange,

duplex TDF flange forming machine provides a perfect solution for that.

Flange forming can be achieved for both ends at a time,

which makes the flanging process much more efficient and stable.

This machine is a top priority for companies who are short of staff

but desired for massive production.

TDF Flange Former,

TDF flange forming machine/TDF rollformer,

mainly used for making flange at edge of plate for further joint,

is also among basic equipments for modern duct forming line.

All bearings used are ball bearings rather than traditional

needle bearings so the machine more durable.

All gears, axles and rollers equipped in the machineare made from

high quality steel to ensure their stability and durability.

The flange shape made by the machine is nice and practical,

which makes it a perfect part of duct forming line.

Our TDF rollformer has two version, T-12 capable of 1.2mm

and T-15 capable of 1.5mm galvanized metal sheet.

Decoiler

This decoiler is specially designed for duct forming line to

make the material loading and transporting stable.

It can hold 5tons of coils.

Lock Former

Preda 7-function Lock former/Pittsburgh machines!  
1.  SA-12HB is capable of 1.2mm galvanized steel and SA-15B is

capable of 1.5mm.  

Main difference between SA-12B and SA-15B is the rollers used.    
2.   To fulfil international customers' requirements on electrics standard.

We are able to change our motors and electrics

as per requested free of charge!!  
3.    380V/50HZ/3PH is the regular standard for our machine.

Yet we can manage them into 220V/50HZ/1PH or 420V/50HZ/3PH...  

Cost is free of charge as a cooperation to our international customers!!!

TDF Folding Machine

Preda Manual TDF Folding machine is specially designed for

HVAC duct folding process.

It can be used together with TDF Flange Forming machine and

Pittsburgh machine to make rectangular HVAC ducts!

Light weight and ease for operating/transport make it suitable

under many circumstances,

especially for short-term working at the construction site.

Machine produced with customerized length can be achieved.
