In the 90s, Volvo and BMW were looking for a new technology to attach the roof. Previously, a seam-welded drip strip had been used. Now it was between gluing and laser. After some testing, it turned out that the glue did not meet all the requirements, which is why it became a laser. In the late 1990s, Permanova installed the first welding and cutting stations. What drove the cut was to be able to make variants of cars without changing incoming items. In the early 00's, the design of some components was changed, which meant that laser soldering needed to be introduced. The advantage of laser soldering is that the joint becomes visually appealing and that it can be painted directly. Over the years, the automotive industry has introduced many different laser-based methods and Permanova can, among other things, deliver solutions for: Laser welding: used by Tier 1 suppliers (those who supply directly to car companies) for welding of roof and A- / B-pillar and for welding of components at subcontractors Laser soldering: common method for soldering roofs and soldering Hang On Parts (HOP) such as tailgate details Laser cutting: component cutting and detail cutting from bodies in final production Laser processing provides, among other things, high productivity, high precision, fast conversion, low manufacturing cost per detail and the possibility of an automated flow. General industry There are many reasons why companies are switching to laser technology. We want to find yours! When we meet a customer, it is usually one of the following challenges or problems that they want help solving: Capacity problems: need more capacity but within the same production area Quality problems: the production gives uneven quality where in the worst case you need to discard products Need for cost reduction: current production methods result in too high a cost per unit Time-consuming finishing: in traditional welding, a lot of heat is added, which often leads to shape changes where direction, grinding and polishing are needed as finishing. Strength problems: can be caused by uneven results due to manual manufacturing Selective curing: traditional curing of the entire component results in deformation with subsequent need for direction and machining (milling / milling) Single-sided access: the product's geometry makes it impossible to use spot welding, for example Variant handling: when, for example, only a few holes or contours differ between products Surface finish: current methods give "ugly" surfaces that require finishing or repainting Deformations: shape changes due to high heat supply, for example during TIG welding For heavy construction: to avoid deformation due to the current welding method, the product must be designed too heavy / rough Need for automation: current manual methods lead to occupational injuries and make it difficult to recruit staff. When we meet new customers in the traditional metalworking industry, we always start our discussions one and the same issue. What is the problem? Every business has something that can be improved. This can be quality deficiencies, the need for higher productivity or stronger construction. The list goes on. Det är först när vi förstår grundorsaken till VARFÖR man vill se över sin produktion som vi kan förstå HUR vi skall erbjuda bästa lösning och VILKEN utrustning som bäst löser problemet.
