RESIF specialists have implemented many projects in the field of reverse engineering, each of which is unique. We decided to introduce you to some interesting orders.

Project “3D model”

A customer needed a 3D model of the part and a drawing with overall and soft chucking sizes.

The necessary measurements were made on the high-precision equipment.

And then step by step, starting with the basic elements the parametric 3D model was built:

According to the model, experts completed the drawing indicating the required parameters.

 

Project “Pump body”

The gear pump body cracked on one side.

Following this sample, taking into account the deformation after a crack in the wall, a model was built.

And a drawing was made indicating all the necessary parameters. At the request of the customer in the model and in the drawing, one of the walls was thickened in order to reinforce the structure.

 

Project “Mill body”

The body of mill for grinding of valve seats worn out and there was a question of replacing it. Search of identical mill body on sale was failed, so that the customer turned to us.

After making measurements of the mill body and analyzing the dimensions of the unworn counter parts, a 3D model was built. The obtained model can be used to write a processing program for the CNC machine.

 

Project “3D model of the cover”

There was a need for customer to strengthen the design of the cover due to the increased load on this part. He needed a 3D model for preliminary calculations, analysis and simulation in the CAD system.

 

Project “Unfolding”

The customer had to re-manufacture a sort of part like a bracket to restore outdated equipment. The part was measured and the model was built in the folded state. Using the tools of the CAD system, the model was unfolded.

The customer can use this unfolding for laser cutting and bending operations and can also make his own changes and improvements to the design.

 

As can be seen from the examples of completed orders, we can offer the customer as a result of reverse engineering

  • 3D model or assembly in any standard format;
  • drawings in dwg, dxf, pdf format, made according to international standards.

 

Models and drawings production is made in CAD system PTC Creo.

The term of execution of order and the cost of works are specified in the commercial offer after analyzing of the sample from the photos or video files. You can contact us via the feedback form or by phone.

Hard anodizing as a new service of RESIF company

RESIF Technologies Bel Company offers its customers a new service for the electrochemical surface treatment of aluminum alloys – HARD ANODIZING (also known as hardcoat).

The thrust of this galvanic process is the producing of a solid and relatively thick oxide film, which in comparison with an usual oxide film provides a significant improvement of the following properties:

  • corrosion resistance, including in aggressive environments;
  • electrical insulation;
  • wear resistance, including antifriction;
  • thermal resistance and heat insulation.

Thus, the technology of hard anodizing allows us to combine the lightness of the weight of aluminum alloy parts with their increased mechanical, thermal stability, as well as their resistance to corrosion.

After upgrading the equipment and three-month technology adjustment, our experts achieved the controllability and repeatability of the process, including high precision sizes and apertures. The coating can be either natural silver- greenish color (photo 1) or painted black (photo 2).

RESIF Technologies Bel guarantees the achievement of the following technical results of aluminum coating with a hard film:

  1. The coating thickness is 40-60 microns (at the request of the customer, it is possible to perform coatings in the range from 20 to 80 microns).
  2. Hardness HV > 300 (controlled for alloy 7075 with a thickness of 25-50 microns).
  3. Wear resistance of 336 hours of salt spray chamber according to NF ISO 9227 (tests have been carried out in our own laboratory, see photo 3 with the results).
