Marking Technology Versatile laser marking system for a wide range of materials
Need to sequentially number small components? Apply bar codes? Mark a QR code on components? All these are possible applications for the new Eneska marker 300 with which Joke Technology is offering a practical and versatile laser marking system.
The new laser marking system from Joke Technology can be used to apply high quality engravings quickly and contactlessly to all metals and many plastics. Even very thin-walled, ground and fine components can be marked accurately and permanently. Since the Eneska marker 300 can also be used to create a deep engraving, the inscription itself can withstand postprocessing (e.g. burnishing). The system is fully enclosed and can therefore be used flexibly at any workstation. The most convincing feature of the marker is the sheer speed with which it applies the desired markings with the utmost precision, the company claims.
The Eneska marker 300 marking system can be used universally — logos, texts, images, graphics, numbering and QR codes are engraved in consistent quality up to a maximum depth of 1.3 mm. Texts can be applied in just a few seconds; an image (e.g. 10 x 8 cm in size) takes about 10 minutes. The dimensions and exact position of the engraving are first projected on to the component before final marking. This provides a preview that not only helps to minimise waste, but also makes it much easier to position the object to be marked. The laser is focused by means of an electrically adjustable Z-axis and two laser pointers that show the user exactly when the laser is in focus. The latter is electrically movable in height and can therefore be accurately aligned. With a maximum pulse energy of one megajoule, the Eneska marker can even cut thin sheets.
A major advantage is the software that can be operated via a graphical user interface. It specifies the most common materials by means of selection menus and has default settings for the appropriate parameters (speed, frequency, power). Likewise, several working stages can be programmed in any desired order. This is very convenient and time-saving, especially for complex markings or markings in series.
With the Enska marker, the marking process can only be started and carried out with the housing door closed. The laser needs to be started with an ignition key — this is impossible with the door open.
Practical handling for many sectors
The parts to be marked do not need to be clamped — this means no mechanical influences and no marks or damage. This is relevant for injection moulding, for example: moulds can thus be deep engraved and this marking can be seen in every injection-moulded part.
The laser is suitable for burnished surfaces. The markings applied can still be read and recognised clearly after burnishing. Small seals that record, for example, the time of production or the ingredients contained can also be applied easily and permanently.
As the system is highly versatile, marking is clear even on rounded components. This is particularly useful for applications such as in the jewellery industry, medical engineering and prosthetics. With clear identification of components (e.g. with an item number), incorrect deliveries and thus downtimes and additional costs are directly avoided during service and maintenance.
Accessories for every user
The Eneska marker 300 comes already pre-equipped with an extraction hose in the working area and a corresponding connection piece on the back of the housing for extraction. Harmful vapours are therefore eliminated directly where they arise. The extraction system is available in various output sizes for different materials and applications. The accessories also include a turning device with metal plate, an X, Y clamping device and a mobile worktable with which this marker can be moved to its place of use.
The Eneska marker 300 is available in two versions. The Premium version is additionally equipped with an automatic door and an integrated camera. In addition, joke offers full-day instruction sessions to establish the device optimally in the company.
The Eneska marker 300 has an output of 30 watts at a wavelength of 1064 nm. The input power is 230 V (50/60 Hz). The work chamber has dimensions of 250 x 250 x 350 mm. The system weighs a total of 100 kilograms. The marking area is 110 x 100 mm in size. The maximum pulse energy is one mJ, maximum frequency 60 kHz. The system operates with air cooling and has laser class 4 (pulse duration 100 ns at 20 kHz).
