3D Scan Technology for an Industry of Constant Innovation

The use of 3D Scann technologies, short production cycles, cost pressures and high quality requirements. This is what forces consumer goods manufacturers to design and manufacture products efficiently. That’s why, 3D scanning systems are used for all production processes – from design and testing of materials to the manufacture of tools and molds. As well as verification and production of the first product prior to assembly analysis and stress testing. If you turn to an outsourcing company that scans and inspects manufactured parts, with a set of additional reports. That the result of quality and speed will greatly help your company. In this way, the launch times for a product launch can be significantly reduced.

One Image Says More Than a Thousand Numbers

And now let’s look at a concrete example from Braun. Using the example of the products of Braun, a subsidiary of Procter & Gamble, you can clearly see the speed and quality at which they bring new products to the market. This explains why Braun has already received numerous design awards for its high quality products and prioritises precision and dimensional accuracy during production.

How it works in practice? Operators simply load the measuring data (STL mesh) and press the update button. Inspection then runs automatically on the second part and includes creation of the evaluation report. I like that the most, because simple work brings precise results. When changes are required in the measurement program, the parametric system transfers these changes to all the elements involved. Hundreds of parts are measured and evaluated in this way at Braun today—during the standardized first article inspection and preproduction inspection processes.

Specific tool corrections

What to expect when using 3d scan? Optical measurement technology is used not only for first article inspection but also for tool correction. To fulfill the high optical and haptic requirements for its products, Braun uses metallic coatings in addition to various materials during manufacture. As a result, the plastic parts have different geometric properties after coating. This means that they can also deform due to mechanical stress.

So like that parts are now measured before and after coating to reveal shrinkage and warpage compared with the CAD model and to reveal any corrections that the tool requires. Just for that for the design engineer to be able to change the CAD model to ensure that the product can be produced with the correct dimensions.

Simplifying technical drawings

Another application of optical measurement technology at Braun is to identify potential problems. These commonly occur on injection molded parts such as weighting materials, offset ejectors, protruding flaps, or even component deformation. Full-screen measurement results allow you to quickly identify them, pinpoint their location and validate them with data. This is a great advantage for mold makers, as they quickly see if and how they need to interfere with the geometry of the tool, or if the parameters of the injection molding machine need to be changed.

By comparing the surface with the CAD data, Braun can determine if a particular problem is in the tool or in the injection molding process. With the help of optical measurement, Braun was able to simplify his technical drawings and inspection reports. While previous test plans were numbered columns, a complete database and transparent classification showing CAD deviations in color now allow easy visualization of evaluation results. Several hundred pages of typical test report tables can be reduced to a few images and functional sizes. Thanks to this, technical drawings can be simplified in advance. To provide a quick overview, component measurement data across the array is compared to CAD data. Controls are reduced to their respective functional dimensions and GD&T elements and then tested.

In conclusion, to sum up, 3D measurement technology enables Braun to guarantee the dimensional precision of the design for all freeform surfaces, specific dimension adjustments during the galvanizing process and the dimensional inspection of all its parts. Another advantage is that it can simplify its technical drawings and inspection reports.
