A cut to length line is a crucial piece of equipment in the metalworking industry. It efficiently cuts metal coils or sheets into specified lengths with high precision.

This automated system streamlines the manufacturing process, reducing manual labor and material waste. By using advanced measuring and cutting technologies, it ensures consistent, accurate cuts, meeting the strictest industrial standards. Ideal for various metals, from steel to aluminum, cut to length lines play a vital role in applications ranging from automotive parts to construction materials.

Zhongtuo cut to length line is composed of four parts: a hydraulic decoiler, levelling and cutting devices, a conveyor, and an automatic stacker.

The advantage of the Zhongtuo cut to length line:

1. Our machine has with 10t loading capacity decoiler, and our decoiler has more functions, such as the loading cart, pneumatic brake, and hydraulic press arm (this is necessary especially for the 2.0mm thickness coils. And our decoiler has the hydraulic support holder, which can let the decoiler work more stably. Here I attached photos with you.

2. Our machine adopts gearbox transmission type, which is more stable and at the same time, life lifetime is longer. If the machine adopts chain transmission, then after a period of time, the chain will loosen, and the customer will have to change the chain. And if the chain is loose, then the machine can not guarantee the cutting precision.

3. Our machine adopts both top and bottom rollers for active leveling, which is better for the leveling precision.

4. There are motors on the top of our machine, which can adjust the roller gap much more easily when you process different thickness sheets.

5. The guide rollers can guarantee the slitting precision. And much easier for adjustment at the same time, not hurt the material.

As we all know, for the same roof tile design, different suppliers have different designs. Here we will help you to analyze from below points about which detail needs to be paid attention when you expand your roof tile business, choose a new machine.

Popular profile drawing for roof tiles:

There are three types of cutting and pressing systems.

1. Split type: Split type cutting and pressing, which will cut after pressing, the blade will cut straight. Also, it will waste 0.7-1.5mm the material when cutting one.
2. Intergrated type: Intergrated type cutting and pressing, there will be no influence between the pressing section and the cutter, which can save materials, but the length of the first section can’t be adjusted.
3. Die cutting (copying cutting)type: high-end version of Die cutting type, which can be cut with lace or straight edges. Which also will save materials, low failure rate, and not be easy to stick with the cutter.

Long Pitch≥350mm: the front section has reached the cutter before pressing, which is easy to deform.

Short Pitch≤:160mm, the distance between the step form device and the cutter is too small, and the two sides are easy to become warped and bent like a boat.

Press depth: The Press depth of the roof tile machine is between 10 mm and 25 mm.

For a 10mm shallow depth, which will save material, the stereoscopic impression is not strong, and the strength is not high.

For 25mm deep depth, which will waste material, but a strong stereoscopic impression and strength is high.

Pay attention to the left and right according to the different requirements of the lap joint. Prevent roof leakage caused by rainwater backflow, with a beautiful lap joint and high strength.

Unique coil processing solutions for metal working

Zhongtuo roll forming machinery is one of leading Chinese coil handing equipment Brand found in 2006. Our mission is provide customer with very best quality metal rolling solutions and after sale service. Our machine offers a wide of coil feeding equipment.

Automatic heavy gauge metal UD profile machine can produce different sizes of drywall profiles with a thickness of 2mm, which can automatically change different sizes by touching the screen. No need to change size manually, it will save a lot of time and enhance the work efficiency for the users.

This machine can produce four different profiles: UD50, UD75, UD100, and  Omega75.

Here is the profile drawing of UD profile machine:

The finished product should be ensured straight and the size should be error-free.

Machine working flow of UD profile machine :

3T Hydraulic decoiler–80T Yangli punching machine—Main roll forming machine—-Runout table

Machine working speed can be 19m/min max, including punching

The UD profile machine has 20 roller forming stations, We use good material Cr12 for the roller material, which we can guarantee a 5-year warranty. The mould frame can ensure stability when the machine is running, and easy maintenance for users.

When you use the galvanized steel material after some time, the zinc coating will peel off and stick to the rollers, then it will affect the use of the machine. Anti-sticking zinc oil injection device will solve this problem. Add the oil or emulsion in the bottle, open the switch, and the oil will automatically drip on the material to achieve the purpose of preventing the zinc coating from peeling off.

80T mechanical punching machine with servo feeding, every time punching 7 rows of holes, the machine’s working speed can reach 19m/min If you want a higher speed, you can choose pneumatic punching.

For the automatic metal track UD profile roll forming machine, there are two screens on the PLC control desk. One is control for speed, one is control to change sizes. Just select the model you want on the touch screen, then the machine frame will automatically translate to the size you want.

Nowadays, metal steel roofing buildings are becoming more and more popular. How to choose a good quality metal roof panel roll forming machine, here we will show you below points about which details need to be paid attention to choose a durable and useful metal roofing sheet machine.

1. Chrome coating

Chrome coating for roller wheels is very important; it can enhance hardness and wear resistance, protect the roller from rust, and make the roller harder. This helps prolong the service life of the roller wheels. Also, enhancing the appearance quality.

The coating test of Zhongtuo roofing sheet roll forming machine ensures that all wheels can guarantee 2.5 to 3 layers or more. If only one layer is done, the useful life will be very short, maybe one month, and the roller will rust.

2. Manual blade

The manual blade of Zhongtuo roof panel roll forming machine should be sturdy and durable so that it can ensure cutting different thicknesses of material. And make sure it will not damage the material.

3.Oiling device

The machine should be equipped with an automatic oil injection device, which can prevent the zinc layer from sticking to the roller.

4. Bolts    8-grade bolts with flat spring washers solve the problem of bolt loosening due to vibration during the transportation, production, and operation of the equipment.

5.  Machine frame  The diagonal support ribs of the frame solve the problem of frame distortion and deformation during loading.

6. Rollers       All the rollers and shafts will have keyways and marked numbers. The keyway of the roller and the keyway of the shaft fit tightly, so the roller will not slip.

7.    Runout table.  The servo tracking cutting telescopic bracket solves the problem of short plate runout.

8. Counter:  The counter baffle solves the problem of the roofing sheet hitting the counter.
