Air Bending

Air bending is the most common type of bending process used in sheet metal.In this process, the work piece is only in contact with the edge of the die and the tip of the punch.The benefits of air bending are as following:

  • Higher versatility with less tooling
  • Longer tooling life
  • Reduced part marking


Coining is a very basic type of bending in which the work piece is stamped between the punch and die. The material is put under enough pressure that the punch tip penetrates the material and it begins to flow into the die. It does however very large tonnages compared to Air Bending.

  • Excellent accuracy and repeatability
  • Require simple machines to execute

Bottom Bending

Bottom bending has similarities to both Air Bending and Coining. In this process the die angle should match the intended angle of the work piece, adjusting a few degrees for Spring Back, hence the existence of 88 degree tooling to achieve 90 degree angles.


Tube bending is a kind of custom metal forming process which is used to permanently form pipes and tubes. According to different requirements, various treatments we used to provide you good- quality custom tubes with high accuracy.

Compression bending

Compression bending is a rather simple method that is often used on production for bending electrical conduits. However, this type of bending has the limitation. It cannot make small-radius bends because the pipe will buckle or break.

Rotary draw bending

Rotary draw bending is a method we use often, which allows for more control during the tube bending process as you use mandrels and dies inside the tube. It can:

  • Make a very tight bend with small dimensional tolerances.
  • Provide a smooth, aesthetically pleasing appearance which makes it an ideal for applications in which bend cosmetics are important.
  • Be used to bend square and rectangular tube and pipe, channel and extruded shapes.

Three-Roll Push Bending

This method is the most commonly used freeform-bending process to manufacture bending geometries consisting of several plane bending curves. And, a 3D-shaping is possible. In a process, the profile is guided between bending-roll and supporting-rolls, while being pushed through the tools. The process is very flexible since with a unique tool set.

Submit your project description and work with a pre-qualified 3D artist, CAD designer, drafter, 3D modeler, 3D animation or engineer specialized for your project needs.

The Project Flow

1. Tell us about your project

Describe your project, estimate the number of hours needed, the duration, and software requirements.

2. Pre-qualified expert freelancer

One of our engineers will contact you to discuss your project and gather more details.

3. Deposit & work

Agreement will need to be signed and payment deposit made in order to begin a project.

FAQ for your new project

Why X-Pro?

We connect you with the best designers in the business, and we offer the most comprehensive set of services for inventors you’ll find anywhere. We take the guesswork out of online design services, and let you focus on what’s important.

How do private projects work?

Simple. Just send us a project brief and we will provide you with a design quote from a pre-qualified designer for your project.

Who can see my project?

Private projects are entirely confidential. Only you and the designer that you will be working with will see your project description, file attachments and submitted work.

Do I own the designs & IP?

Yes. Our legally binding terms of service assign the ownership of intellectual property (IP) from the designer to the service buyer for any paid designs.

Do you offer manufacturing services?

Yes we do! We offer a range of  manufacturing services, including 3D printing, rapid manufacturing and conventional injection molding.

How is a design project different from hourly services?

Design projects are limited-term projects with a concrete budget, based on an upfront quote from the CAD designer. Hourly services are for ongoing work that generally have an open work scope.

Will designers sign a NDA?

We’ve got this covered. Our legally binding terms of service covers freelancer non-disclosure. Freelancers on X-Pro have agreed to and are bound by the terms of non-disclosure that are outlined in our terms of service.
