Conventional glass cutting or laser technology? Edge grinding or polishing? From an array of possible glass processing technologies, which one is the most optimal for an automotive display application? Let\u2019s find out.    <\/em><\/p>\n

What do you expect from a modern car dashboard? For at least a decade, most automotive dashboards are packed with displays of all sorts. Whether it is navigation or an entertainment system, speedometer or driver assistance tools, when it comes to interior displays, one thing is clear \u2013 car manufacturers are in a constant search for even more sophisticated and cooler designs, because they know we love them.<\/p>\n

Car exteriors, as well, are continuously enhanced with innovations in automotive glass that enable better, more durable \u2013 and more intelligent glazing.<\/p>\n

But first, for all these advanced automotive display glass applications to exist, glass needs to be processed. And it needs to be done precisely and in the most practical way.<\/p>\n

Luckily, glass processing technologies don\u2019t stand still. With a wide range of glass processing solutions available, there are plenty of options to choose from. <\/p>\n

There are several basic processing strategies for display glass:<\/p>\n

    \n
  1. Conventional cutting and edge grinding<\/li>\n
  2. Laser cutting and full edge grinding<\/li>\n
  3. Laser cutting and edge polishing<\/li>\n
  4. Conventional cutting and edge grinding
    \n+<\/strong> laser cutting the elements that cannot be cut conventionally<\/li>\n
  5. Conventional cutting and edge grinding of the outer contour
    \n+<\/strong> laser processing of the inner features<\/li>\n<\/ol>\n

    Each strategy has its advantages and disadvantages. The optimal processing technology always depends on the display glass application and its requirements. Different applications require different specifications.<\/p>\n

    Thus, edge strength, maximum chip size, edge shape and dimensional tolerance are all important and dictated by each specific customer application. For example, laser cutting makes an almost perfect rectangular edge. However, it is only acceptable in a limited number of situations, which should be checked case by case.<\/p>\n

    In addition, each technology\u2019s cycle time and costs vary, too. Conventional cutting and grinding might indeed be the fastest and most cost efficient. But this processing strategy is not right if the required display needs to have any integrated internal features.<\/p>\n

    These days, it is only by combining conventional cutting, laser cutting, grinding and polishing technologies, can you master display glass processing. This \u2018combo strategy\u2019 is the only one allowing glass to be really tailored to individual needs.<\/p><\/blockquote>\n
