SEI Laser

Revitalisation of the Skoda Garde engine. Removing paint, cleaning grease and dust without disassembling the engine.

The refurbishment of plain bearings is very simple thanks to laser technology. The pulsating laser beam penetrates the polymer layer and breaks the bond between the polymers and the metal. The polymer can then be easily removed.

Use of laser cleaning to remove dirt while blasting to create a solid anchoring profile that is ideal for new paint application

If a new coating is required, the old coating must be completely removed and the surface free of dirt. This can be achieved using laser technology.

Thanks to a quick laser cleaning, congealed lubricants and surface rust caused by storage in damp areas were removed

The laser removal of organic deposits and old paint from the steel structure is effective, meets all environmental protection requirements and does not damage the existing surface.

Thanks to the laser beam, the adhesive can be precisely and efficiently removed from the surface of the rollers. No bearing disassembly is required and the entire process takes less than one hour.

In this article we explain the importance of the individual parameters of cleaning lasers, the fundamental principle of laser cleaning and the applications for which each power series is suitable.

Restoration, graffiti, dirt or soot removal, none of this is a problem for the ROD cleaning system. The laser is particularly suitable for very sensitive restoration of monuments or historical objects.

Laser mould cleaning covers a wide range of applications, including mould presses, tyre moulds, baking moulds, injection moulds and more.

In connection with the increased production volume, there was a need for additional equipment for cleaning of technological equipment. Two cleaning methods were considered, ultrasonic and laser. As a result, the decision was made in favour of laser cleaning due to its low operating costs, efficiency, material and environmental friendliness and mobility.

ROD cleaning lasers have countless applications and more are added every day, in this mini case-study we focus on the use of the ROD 200 in the Autochladiče Hladík company.

Undoubtedly, the biggest advantage of ROD laser systems against other cleaning laser devices is the perfectly thought out process head, because you, as a user, will hold this very important part of the laser cleaning machine in your hand every day.

We believe that our lasers are the best choice for your business. In the article, we focused on several points that differentiate us from the competition.

The laser is not a cheap thing, the development of a laser is demanding and expensive, its production requires both a huge amount of time and money. We stand firmly behind the price of our lasers, because we know that it is not possible to drive the price lower, certainly not so that the quality or functionality of the laser does not suffer. Unfortunately, no one, not even China, has a miraculous method of manufacturing lasers, where it would be possible to produce a laser for a fraction of the price so that the quality is at least close to the products and services we provide.

In January of this year, we designed and delivered a unique marking custom-made Veles Fiber F30 workstation to PrusaLab – the open workshop of Josef Průša. The workstation is unique thanks to its large work area of ​​400x400mm. The unit was created from the ground up in our workshop in Vysočany, Prague.

Laser cleaning uses concentrated laser radiation to evaporate impurities from the layer. The impurities are affected by ultra-short laser pulses (μs-ms), which generate heat and heat-induced pressure - the high temperature inside the material creates a high pressure that causes it to evaporate.

We have newly installed the SISMA SWA 150 welding laser with a peak output of 10.5 kW.
Fully automated XYZ axes ensure a trouble-free automatic laser surfacing function with and without additional material.

In 2019, we installed a state-of-the-art SEI flexi 600 engraving, marking and cutting laser station for Sonus, which creates graphics and promotional items.

LGP (Light Guide Panel) light panels, also called BLU panels (Back Light Unit), are used as backlit advertising areas or lighting areas in luminaires. In the plexiglass panel, there are laser-engraved tiny dots or lines that guide the light, supplied by LEDs typically located on two or all four edges of the panel.
