Stainless-steel/Metal laser engraving on the larger scale Supplier SignSeen installed a machine usable for large format metal marking and engraving at engraving company Gravure’85. "Laser engraving large format materials is a quite particular craft within our industry", Jan W. Leendertz, managing director of SignSeen, U.S.. So far, the supplier has only sold this type of devices to the industry. Those assuming that laser engraving or marking is not possible for large format metals, are mistaken. In fact, Dutch industrial engraving company Gravure'85 has proven the contrary. Ernst Hendriks, owner of Gravure’85, wanted to find a machine capable of marking and engraving large (stainless) metal plates in one pass. His search eventually led him to the Dutch supplier SignSeen (Veenendaal, the Netherlands). Customer base "We have a large customer base," Hendriks commences. "We get orders from several signing and engraving companies, but also from companies within the food industry, hospitality industry, shipping industry, utility building, offshore industry and morticians. C02 laser is known for requiring a special paste in order to work directly on metal, but in the long term the end result becomes brown, pale and rusty resulted from exposure to the elements. Moreover, marks are placed on the metal surface instead of being engraved in it. This can create problems in, for example, the food industry, where HACCP standards must be guaranteed. Engraved plates have to be properly cleaned using high water pressure equipments and meanwhile the marks need to resist color change or fading. The same goes for the engravings on memorial plaques and ornaments; texts and pictures have to maintain their novelty for years. Deep black Gravure'85 had ample motivations to look for the right machinery. The company frequently receives requests to add a name, date or line of text to an existing panel or board with the same color and density as the original text. Generally, letters have to look nice and solid black from every angle while high durability of the results must be ensured. Gravure'85 occasionally has requests for engraving on large format materials. "Regarding the latter, we have done lots of testing. When you re-enter a plate into a machine in order to make the second part of a marking, you inevitably get color differences between the first and second marks," Hendriks says. "Our goal was to engrave a large plate in just one single passage through the machine. However, in many machines the chassis is sealed, thereby making single passages impossible.

Fiber Laser SignSeen provided the solution to this problem by placing a LaserPro GCC S290LS-40 laser marking machine at Gravure'85." Jan W. Leendertz first had to convince me of the quality this GCC laser delivers”. I have been the representative of Gravograph Benelux for more than eighteen years, so making a switch to a different brand was not an easy step for me. Jan W. Leendertz: “This GCC laser engraver is a fiber laser machine with working area of 790 x 460 mm, available in 20 and 40 watt versions”. The technology itself is not new; we have been selling this type of machines for some...
