Frequently Asked Questions


Ordering procedure for the machine?

  1. You send us technical drawings for the profiles which you would like to bend on our machine
  2. We will then send you our pro forma invoice for the machine with the tools for your profiles
  3. We are signing the contract on buying the machine
  4. You make the payment of the advance (50% of the total price)  and send us samples of your profiles 20cm in length
  5. We will make the tools for the profiles and prepare the machine for you
  6. Your workers will then come to our company for the three-day training.
  7. After the training, when the machine and the tools are ready for transport, you will make the payment of the remaining 50%, and the machine will be sent to your company within three days.

 

What arches types can be bent on our machine?

Please, observe following drawings:

Arches types   Bending axis


How much time is necessary for profile preparation and bending?

Required time mostly depends on the length of the profile so, for the preparation some 15 – 20 min is necessary while the bending process lasts 7-8 min.

What is used for filling the profiles?

All profile chambers are filled with quartz sand.

Why are profiles closed?

 

Profiles are closed to stop sand from dropping out from the profile during the bending process.

Is sand thrown away after use?

 

Sand is not thrown away after use. On the contrary, sand is becoming better for bending after use and it can be used unlimited number of times. 

What is the maximum height of the profile bent on the machine?

 

Maximum height of the profile bent on the machine is 120 mm.

What is the maximum width of the profile bent on the machine?

 

Maximum width of the profile bent on the machine is 110 mm.

Why are profiles and rollers lubricated with oil?

 

Profiles and rollers are lubricated to reduce the friction between them.

Which arch types can this machine bend?

 

In automatic mode the machine can bend all regular arches with and without verticals, part of the circle arches (circular section) and arches with two radii where the part in the middle is straight. Arches with three or more radii are done according to a pattern and in the manual mode, with operator controlling the machine using buttons on the machine.

Color of the machine?

Standard color for the machine is blue. Machine is also available in red color.

 

 

Installation procedure for the machine?

 

Installation procedure is very simple. It is only necessary to connect three-phase plug to the machine power cable and connect the machine to a three-phase electricity source. No additional adjustments are necessary.

How is PVC profile heated?

 

PVC profile is heated on the machine, during the bending process, using hot air. There is no additional preheating of the profile in a bath or a heating chamber. Temperature on the profile during the bending does not exceed 50-60 degrees.

Can the machine bend PVC without steel?

 

Of course our machine can bend PVC without steel. This bending process is almost identical to the bending process of the PVC profile with steel.

Can all arch types be bent with steel reinforcement?

 

On our machine it is possible to bend any arch type with steel reinforcement without difficulties. However, it was proved in practice that bending circular sections with steel causes additional problems in further processing of the arch (cutting problem, welding problem…). So, in practice, only regular arches with verticals are bent with steel.

Maximum length of the profile (maximum radius)?

 

Maximum length of the bent profile, in other words, maximum radius the machine can bend is unlimited. Our technology is not limited with plastic caterpillars as other technologies are, so, there are no length restrictions for the profiles on our machine. 

Minimal radius?

 

Minimal radius depends on the quality of the bent profile. With quality profiles and standard profiles 45-50 mm wide, minimal radius of 150-175 mm can be achieved.

Warranty?

 

Warranty for the machine is one year.

Procedure in case malfunction occurs on the machine?

 

In case malfunction happens, you should inform us about the malfunction via e-mail or telephone as soon as possible, and our technicians will find a solution for the problem as soon as possible. If the elimination of the malfunction requires replacement of the malfunctioning part, spare part will be delivered to you in the shortest period, and, if it is necessary, we will send our technician to replace the malfunctioning part. Our company covers all expenses regarding the repairs done in the warranty period. After the warranty period we remain at you disposal if you need any logistic or technical support.

Training for the machine?

Complete training for the machine handling lasts three days and is free of charge if it is executed in our company and, in this case, buyer is obliged to cover only the expenses for transportation and accommodation for his workers. Training is extra charged if the buyer decides that training should be executed in his company. Buyer is then obliged to cover the accommodation expenses for our technicians and to provide transport for them from the airport to the company.

Is surface or color of the PVC profile damaged during the bending process?

 

Surface or color is not damaged during the bending process, because the profile is protected with the protective tape and is lubricated with oil thus eliminating the friction between the profile and the tools.

Is surface or color of Aluminium profile damaged during the bending process?

 

Aluminium profiles are bent without any damage done to the outer surface, because the tools for these profiles are made from special plastic and even the color of the aluminium profile is not damaged.
