Case.2_Design+Precision |
| ---------------------------------------------------------------------------------------------------------------- |
|
 |
| Client |
| Great manufacturer of metallic structures for automobile seats. |
|
|
|
Case.3_Concentricity |
| ---------------------------------------------------------------------------------------------------------------- |
|
| Client |
| Solution for a manufacturer of automobile engine components |
|
|
|
| Situation |
| Develop shafts for engine camshafts, with the quality and specification required by the assembling car companies. |
|
|
|
| Piece |
Shafts for engine camshafts
Year: 1998
|
|
|
|
| Challenge |
| For safety reasons, the engine shafts needed to be manufactured with maximum precision, with correct flatness, concentricity and centesimal tolerances. |
|
|
|
 |
Solution |
| EBF developed special tools to perform blanking of the shafts, which are very delicate pieces that need to be accurately manufactured. For this reason, we employed the fineblanking technology, which enables to obtain the length, flatness and concentricity within the specification value ranges. |

Case.4_Design+Variety |
| ---------------------------------------------------------------------------------------------------------------- |
|
| Client |
| Solution maid for a large brake disc pads manufacturer |
|
|
|
 |
Situation |
| To manufacture plates, reducing the number of manufacturing process stages, without affecting the specifications required by the assembling car companies, improving the quality of these pieces. |
|
|
|
 |
Client |
Large variety of plates for brake disc pads.
Year: 1988, 1990 and 1998
|
|
|
|
| Challenge |
| Difficulties in fulfilling the demand and the requirements related to the dimensions specified by the assembling car companies. Besides, the several stages following the traditional blanking process increased the cost of the pieces. |
|
|
|
 |
Solution |
By using the fineblanking technology, we obtained the following results:
> we’ve performed blanking in a large quantity of brake plates;
> we’ve maintained the quality and the specifications required by the assembling car companies;
> we’ve reduced the number of stages after the blanking process, thus lowering costs.

Case.5_Performance |
| ---------------------------------------------------------------------------------------------------------------- |
|
| Client |
| The solution maid to one of the largest brake componets maker: plates [brake disc pads] and brke shoes [brake-drum]. |
|
|
|
 |
Situation |
| The brake shoes in the market were welded and presented manufacturing problems. |
|
|
|
 |
Pieces |
Drum brake shoes.
Year: 1995
|
|
|
|
| Challenge |
| The shoes were welded and the piece presented dimensional problems, in the shape, perpendicularity, among other distortions. |
|
|
|
 |
Solution |
By replacing the welding system with the rolling system to manufacture the shoes, we got to:
> solve the problems of distortions in the pieces, which now are beaded and not welded anymore;
> obtain improved quality and improved performance, attested by the pull-out tests, which were beyond all expectations of the assembling companies.

|
|
Case.6_Thickness+Agility |
| ---------------------------------------------------------------------------------------------------------------- |
|
| Situation |
| Manufacture flanges to fulfill the automotive market demand. |
|
|
|
| Pieces |
Variety of flange models
Year: 2004
|
|
|
|
| Challenge |
> Produce these itens in Brazil to exchange the imported supplier;
> Avoid flatness problems;
> Cut manufacturing processes.
|
|
|
|
| Solution |
| By using the fineblanking system, we got to obtain flanges of 13mm thick, we improved the flatness of the pieces and eliminated the grinding stage, which was just after the blanking stage. |
|
|
|
Case.7_HighSkill+Flatness |
| ---------------------------------------------------------------------------------------------------------------- |
|
| Situation |
| Manufacture a variety of flanges for exhaust car systems. |
|
|
|
| Pieces |
Flange for car exhaust pipes.
Year: 2004
|
|
|
|
| Solution |
| In order to meet the customer’s specifications for flange length and flatness, we also employed the fineblanking technology in the manufacturing process. |
|
|
|
Case.8_Quality+Efficiency |
| ---------------------------------------------------------------------------------------------------------------- |
|
|
|
|
| Situation |
| The valve plates used before presented problems while performing of their functions. |
|
|
|
| Pieces |
A variety number of valve plates
Year: 1994
|
|
|
|
| Challenge |
The valve plates for Low Back Pressure (LBP) of evaporation application, needed an improvement on:
> lowering noise;
> increase energy efficiency; and
> avoid gas leak problems.
|
|
|
|
 |
Solution |
By using the high precision blanking system (fineblanking) we could:
> develop plates of compact dimensions;
> develop plates of low noise level;
> develop better finish and precision area;
> high energy efficiency.
The successive investments in new tools, technologies and processes have made us specialists and the only manufacturer that produce valves using the fineblanking process: 1,500,000 pieces are manufactured each month.
