Glazing

MGRD’s full glazing development services are provided both directly to carmakers and indirectly to systems and components suppliers.

MGRD’s full glazing development services are provided both directly to carmakers and indirectly to systems and components suppliers.

With the evolution of car designing, the area occupied by glass in the vehicle is in continual growth, while at the same time the obstruction of the field of vision by surrounding elements has been reduced to a minimum. In addition, the development process of the style model and the glass shapes resulting from them still require care, not only from the construction point of view, but above all from the functional ones, like distortion-free images, movement possibilities and achieving targets of play and profiling with surrounding elements. Thanks to its know-how in body and trim development in the preliminary feasibility stages, MGRD is the ideal partner for creating a glass, both for an advanced feasibility stage and for detailed component planning.

MGRD has gained a wealth of experience in the development of all vehicle-glazing systems: laminated, tempered or encapsulated. MGRD is able to put together the right team to create an organic system of interaction and communication, thanks to FLASH, with all the customer’s departments and suppliers.

Our main services cover important areas and stages such as:

Sealing section definition:

  • Interface verification from the preliminary feasibility studies.
  • Glasses components packaging/design and serigraphy definition.
  • Benchmark and lesson learnt analysis

  • Assembling verification and reference system definition
  • Modification proposal for the interfaces
  • 2D glass and completing components section definition
  • Contour Sealing approach verifications
  • Bill of material creation management (BOM)

Sealing modelling/detailing

  • 3D solid modelling of the contour sealing extrusion or moulded for the encapsulated solutions
  • Confirmation of the extrusion positioning and section
completed with the interfaces
  • 3D solid modelling of the junctions and all co-moulded parts
  • Constant approach condition verification of the movable parts
  • Co-moulded feasibility with suppliers

Sealing optimization and problem solving management

  • Glass curvature analysis and its optimization in A class surface quality
  • Side door glass drop feasibility
  • Manufacturing and supplier discussion for the related solution optimization
  • Physical test results analysis

  • Final drawing release

Benchmarking:

In addition to the vast database of components for the preliminary planning stages regarding sections and extrusions, MGRD is able to supply specific benchmarking data which, through systematic dismantling, is capable of providing:

  • Geometrical solutions description with related pros and cons.
  • Fixing/joining/assembling strategies

Integrated activities:

  • Glass curvature analysis
  • Virtual glass assembling and disassembling feasibility
  • Side door Glass drop feasibility and related glass 3D optimization
  • GD&T 3D tolerance chain simulation: the activity is carried out using 3DCS software and can be addressed to all systems which interface the seals also starting from data already calculated for other systems.
    The aim is to understand under what working conditions the seal could be obtained in order to be able to optimize its characteristics and relative behaviour with the interfaces. Thanks to our diagnostic experience, and using the same software, we are also able to perform post-production verification through reverse engineering methods in order to optimize the existing solution.

Range of glasses Engineering:

  • Wind shield
  • Side door tempered/laminated glasses and for all door typologies.
  • Back lights
  • Quarter glasses front/rear encapsulated and with side door glass channel
  • Sky dome
  • Sliding glasses
