The Italian company Blacks S.r.l. was established in November 2011 by a group of young but experienced specialists in composite materials and specializes in the design, prototyping and manufacture of components in advanced composite materials (carbon, glass, aramid, hybrid fibers). The company offers the design and production of composite and metal parts for the automotive, aerospace, marine and sports industry.
Blacks customers require extremely high dimensional accuracy. For this reason, the company has always been equipped with 3D measuring tools. The 3D measurement technologies are used on a daily basis in the dimensional control and validation of incoming models, molds and outgoing components. In some cases, the technology is also used in the case of reverse engineering, to support production and design, simplifying the production process.
In order to enhance its metrology equipment, Blacks decided to acquire the portable 3D scanner MetraSCAN BLACK from Creaform. The system convinced due to his scanning speed compared to previously used systems. Besides, no spray needs a be applied on shiny parts and targets are not necessary. The Creaform system is faster, more versatile, and efficient in all situations and can be used for a wider range of applications.
As Blacks already used a wide range of different measurement systems, it was easy to implement the new system, as using the Creaform scanner is very intuitive. The operators quickly became familiar with the new tool and used it quickly to its full potential.
MetraSCAN 3D ensures the perfect gluing process
The MetraSCAN 3D was used to check the bonding between two components. In the composite materials sector, bonding between two components generally takes place with the help of specific jigs to prepare and maintain the mutual position of the two parts during the adhesion.
Let’s take an example from the racing car starting with the following assumptions:
- The components for racing cars have very stringent homologation parameters (+ – 0.5mm / 1000mm)
- The constrained dimensions are measured on the bonding and not on monolithic components.
- The gluing reaches very high complexity, with important manual adaptations. Bonding is done between components with both machined and hand-worked areas.
- The gluing templates are calibrated to achieve the result but, in some cases, it is not possible to rely only on the templates: the composite material components, during curing, can undergo large deformations due to unbalanced layers. These deformations are not always perfectly predictable so the component may not adapt perfectly to the template.
In these conditions, which frequently occur in the production of prototypes for the motorsport sector, having a real-time control of the gluing, therefore during the adhesive consolidation process, allows to reach the optimal result in the production phase.
This is what Blacks did: “Since the value of the glued assembly was greater than € 15,000, it was decided to proceed with a gluing template and continuous monitoring during the hardening phase of the adhesive, to ensure the correct mutual positioning of the parts.”
Could Blacks have done the same check with the old measurement tool? They are not able to say, as the strong limitation of the opacification of the surfaces has always discouraged them in the attempt.
This particular use of the MetraSCAN 3D differs from the daily use like mold inspection and dimensional control at Blacks, however it demonstrates how it is functional in all cases of gluing prototypes or setting up glued components without the need to create dedicated gluing equipment.
