Q.Are you a manufacturer or trading company?
A.We are a manufacturer; Wonsten is our group trade mark. We focus on metal pipe/tube processing machinery.
Q.How to choose the pipe/tube bending machines?
A.You have to inform us following details:
- Pipe Material:
- Maxi. Outside Diameter:
- Wall thickness Range:
- Bending Radius(CLR):
- The drawings/samples if possible:
Q.What is the difference for NC, NCSL and CNC machines?
A.NC is standard hydraulic pipe bending machines, feeding and rotation are manual, and bending is hydraulic automatic.
NCSL is semi-automatic pipe bending machines, mechanical gear feeding, servo motor automatic angle rotation and hydraulic automatic bending.
CNC is fully automatic pipe bending machines, servo motor for feeding and rotations, and hydraulic or servo motor for bending, multiple tooling stack are available for two and more different bending radius (CLR).
Q.What is the language of the PLC and touch panel?
A.Don’t worry, we will translate the language in English,Spanish or any other language, to make sure you will have an easy operation.
Q.How does your factory do regarding quality control?
A.Quality is our culture.
We attach great importance to quality controlling from the very beginning to the very end.
Q.What about machine quality guarantee period?
A.A: One year.
Q. Where is your factory located? How can I visit there?
A.Our factory is located in Suzhou city (beside to Shanghai).You can fly to Shanghai Hongqiao or PVG airport directly.
All our clients, from home or abroad, are warmly welcome to visit us!
Q. What file formats are you able to accept for drawings?
A.We are able to open and use .DWG, .DXF, .STP, .IGES, .SLDPRT, .PDF files. As long as when you submit a drawing you include some important information we are able to provide you with a quote, these are Outside Diameter, Wall Thickness, and material type, grade and preferred Centre Line Radius.
Q. What materials are you able to bend?
A.We are able to bend Mild Steel, Stainless Steel, Aluminium, Copper, Brass, Inconel and Duplex alloys. If you are looking for a material that isn’t listed, please contact us and we will be happy to talk about your requirements.
Q. Do you accommodate small production runs?
A.Yes, we can produce 1 off prototyping or larger volume production.
Q.Can we free issue our own material?
A.Yes, we are happy to use your own free issue material or source material for you.
Q.What is the largest diameter you can bend?
A.10mm—2m O/D
Q.What is the longest length you can accommodate?
A.Customized
Q.Can I pay by credit card?
A.No, we do not accept payment by cards. Our bank details are found on the bottom of our invoices.
Q.What Is Outside Diameter (O/D) of Pipe Bending Machine?
A.The measurement across the widest area of the pipe or tube*
Q.What is wall thickness (W/T) of tube bending machine
A.The measurement between the outside and inside surface of a pipe or tube.
This is also referred to as schedule in pipe or gauge in tube.
Q.What is degree of bend of CNC Pipe Bender
A.The angle of the bend. This is taken on the OUTSIDE of the bend
Q.What is straights between bends of CNC Tube Bender
A.If your part requires more than one bend there will be a minimum straight length that we will require between the bends. This is also known as the clamp length. Using our tooling list, you are able to see the minimum clamp length for any size tube and the associated centre line radius bend die from our stock tooling.
Q.What is tube bending machine processes
A.Mandrel Bending
Tube is bent around a fixed radius die with a mandrel insert in to prevent it from collapsing during bending. The tube or pipe is clamped against the die and this is then rotated whilst the pressure die moves in a straight linear motion. See our mandrel bending video for a brief overview. This is the most common form of bending.
Roll Forming (Rolling)
Tube is rolled through three rolls that allow it be formed to a large centre line radius. See our rolling video for a brief overview.
Compression Bending
Compression forming is an original technique of bending tube. The tube is clamped in place and the pressure die is moved around the radius creating the bend, the opposite to mandrel bending. This method doesn’t allow use of a mandrel.
