An Italian company is looking for laser technologies for cutting special lens filters
A small dynamic Italian company has a leading position in a niche market for architectural light projectors and special lens filters (called "gobos") to create indoor and outdoor decorative scenes for events, brand promotion etc. They ares looking for laser based techniques to improve the precision and speed in cutting gobos lenses by customising an existing solution or by collaborating in the development of a new machine under a technical or commercial agreement with technical assistance.
Technical Specification or Expertise Sought
Partners are expected to have an extensive experience on laser technology and related industrial application to be able to analyse the problem and identify a solution by customising existing technologies or developing a new one. The main technical specifications of the request are: - glass: borosilicate, thickness 0.55 to 2mm - cutting speed > 2mm/sec - size needed: diameter from 5mm to 60mm or more - starting size: rectangular plates of different sizes, tipically 110x160mm - very good quality of the edge after cutting process
Partners sought: industrial or academic partners with a proven know-how on laser technologies and related industrial applications. Partners are expected to provide a thourough analysis of the issue and identify a suitable technical solution. In case of an existing or easily customisable solution, the companies will establish a commercial agreement with technical assistance. Alternatively, the companies will collaborate under a technical cooperation agreement in the design and test of the new machine while the partner will carry out the tecnical development.
An Italian SME has developed, over more than fifteen years of activity, a very competitive solution for creating impressive "landscapes" of lights, for indoor and outdoor use, by coupling architectural projectors and special lens filters ("gobos"). The company started in 2002 with the production of high quality, customised gobos to be used with general purpose projectors, and is now the leading company in Italy and one of the world's leading gobos producers. In addition, over the years, the company has developed its own line of dedicated projectors, with significant advantages in terms of reduced costs and energy consumption, compact size and ease of setup, light weight, robustness. The company, originally located in the south of Italy, has opened a second production site in the north of Italy and it is directly present abroad with two production sites in France and California, and with a sales office in Germany. Gobos Gobos are very thin dichroic glass filters or metal discs that are used to project images, texts, logos, including very colourful pictures, with high precision on very large surfaces (eg. walls, buildings, squares, stairs, etc.) and in different situations (eg. fairs, ceremonies, meetings, local festivals, safety signs, etc.), possibly with dynamic effects (eg. rain effect). The overall solution is very effective for promotion, entertainment and artistic communication, starting from single projections up to the creation of complex itineraries and landscapes, using multiple projectors and gobos, The company has a catalogue with more than 1000 standard gobos, grouped by themes, to be used for the creation of various scenes and is able to create customized gobos upon request with very short-term delivery. Currently, the design and customisation of gobos is done using a clean laser-etching process on dichroic filters, with quality materials and digital manufacturing techniques ensuring high brighteness, fidelity and colour brilliance, no imperfections and unwanted reflections and with a low environmental impact. Also, innovative materials and production processes make gobos resistant to very high temperatures (over 450°C). The request At present, the basic lenses to produce gobos of different sizes are cut out of large glasses using micro-grinding machines. This step could be enhanced in overall speed, material usage and edge quality after cutting by using laser technologies but, so far, the company has not found an adequate solution. Specifically, the solution should be able to achieve a minimum cutting speed of 2mm/sec, for lenses with diameter from 5mm to 60mm or more, by optimizing cut of rectangular plates of different sizes, tipically 110x160mm, and clearly with a very good edge quality after cutting. Glasses are borosilicate with a thickness from 0.55mm to 2mm. The company is looking for industrial or academic partners that are able to provide a thourough analysis of the issue to identify a suitable technical solution. Partners should have a specific know-how on laser technologies and related industrial applications. In case of an existing or easily customisable solution, the companies will establish a commercial agreement with technical assistance. If the solution is to be developed, the company will collaborate under a technical cooperation agreement in the design and test of the new machine while the other partner will carry out the tecnical development.

EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
