Third part of the special that the number 27 of Sistema Serramento dedicates to TWT. Interview by Filippo Pellitteri, President and CEO of the company.

Following is an excerpt from the article published by the German magazine BAU that talks about other company features, about the unusual nighttime visit with the German journalists, as well as about the new Laser HP tools (Bauelemente-Bau 01/20).

“It is pitch dark in the production room. One barely recognises the outlines of the machines in the dim light of the lamps. No wonder, seeing it’s way past ten p.m.!No operator visible, and yet production goes on at TWT s.r.l.. The lights of the operator terminal, the arm of the clamp that is changing a new tool, and the light hum of the grinding machinesand of the CNC processing stations prove it. Once again, a night shift is being conducted to complete an order for products intended for some fair.

The TWT company of Rovereto can offer its clientele models of tools for the production of wooden windows and doors as well as its experience in highly automated manufacturing processes including autonomous production. The project of Rauh Fensterbau GmbH, that today is capable of producing up to 120 different systems, is an excellent example of the various concepts of single tools implemented for clients from all over the world. With its 51 employees, TWT s.r.l. is a family-run company of manageable proportions.

However, thanks to its specialisation in tools for the manufacturing of wooden windows and doors, the company ranks third among the leading companies operating on the European market in this sector. In order to be able to position itself successfully on the international market against significantly larger competitors, this company applies a strict quality policy that includes all of its employees. TWT also is always attracting attention thanks to its new tool concepts, coating technologies and its very high flexibility, that all contribute to building loyalty among its clients.

The company is also capable of doing this with the Laser HP (High Performance) system of tools that will be presented to the public as soon as the Coronavirus emergency ends [Editor’s note], a solution that sets the new standard for high speed processing at over 120 metres per second. TWT has developed a completely new system of tools with the intention not only of achieving high speed cutting with low noise levels but also of guaranteeing smooth operation and therefore high surface quality.

The company has steadfastly pursued its “zero tolerance strategy”. The screws normally used to fasten the cutters cause additional tolerances. It has therefore developed a fastening system for the end stop and thecircumferential cutting edges in which the screw no longer affects dimensional accuracy. When the knives are inserted they are pushed into the correct position by built-in springs. Moreover, the knives are set in place axially via a slot. Instead of sintered cutters, the round bars made of H5 ground carbide (tolerance 0-8 micrometres) are used as basic components and also for the millers. All fastening screws can be reached radially. Only one tool is required to install the cutters. This eliminates the recesses required with vertical screw connections.

All this results in the compact design of the body of the tool base with extensively closed disks, which translates into significantly reduced turbulence and therefore lower noise as well as better chip evacuation. The tools are already being used by pilot clients and all testing has proved successful. The spare parts warehouse is currently being set up in Rovereto and will be ready for delivery in March.It is a new system of tools for mechanical engineering, patent pending, that brings the tool manufacturer closer to the machine manufacturer because the machinery that reaches its limit with conventional tools due to the vibrations they generate can be used with the Laser HP system at very high speeds without the need for a heavier body”.

The multidisciplinary environment in which the large building construction market to which we refer moves still remains complex and involves the trends concerning the finished product specifically in the windows and doors sector, while the products and materials involved give rise to an even wider range when one includes composite materials. How much weight does the wood sector still have in TWT’s business?

“Wood is our core market and the product on which we focus most of our efforts. It remains the core market also as regards our specialisation in the production of wood and wood/aluminium windows manufacturing tools because these windows are a leading product on the European markets. Therefore, coherently with the history of the three brands united in the TWT name, the company maintains a prominently green vocation because it continues to focus on wood with highly specialised competence”.

If we imagine the production of a window as its production cycle is completed, and the high quality finish of the final product, one will see that there are many figures involved in designing and creating it. Could one claim that the window and door production chain (communication included) has been “shortened” thanks to the digital language that can put the architect in communication with a work station operator?

“Yes, it’s true, the client is becoming increasingly involved in the design and is always open to new solutions to be shared with the architects”.

“At design level, this is especially true for the Italian market, and actually for all of southern Europe – states Nicola Pedrotti –, but as regards communication there is the window manufacturer who interfaces via the Internet with the machine manufacturer when there is a problem in foreign countries too. In particular, it is a question of mentality that involves the entire Mediterranean area, that includes France and Spain too as well as Italy, a culture that derives from history and that leads to the restoration of the existing pool of buildings that is the largest point of reference in this geographical area”.

When I wrote on the blog about TWT I prefigured the idea of products/materials that concur in creating an increasingly more complex window and door system but with the technology currently available and evolved also in terms of maintenance and the replacement of parts that possibly do not require the removal of opening lights and frames. How does the president of the Trentino company, Filippo Pellitteri, imagine the window of the future will be?

“For those seeking a high quality and durable product, the market offers a wood/aluminium system that eliminates the need for external maintenance while ensuring the beauty and warmth of wood indoors. The challenge will be to create a wood/aluminium system that effectively costs less than the current one and that can provide the same performance. To this specific end we are working together with Europrofili in developing an innovation for the Esperia project. This is one of the synergies I was talking about earlier and that we are conducting.

The same logic is followed with the synergy with Roverplastik, which you previewed as a journalist on Roverplastik’s Press Day held on 21 January. This important partnership was born from the need to give the Italian market not just a classical product like many others, but to share a project by placing on the market the different expertise of the two companies in testing and certifying the various products”.

Can bonds such as those created with Roverplastik create synergy also in terms of service on the global market?

“They can certainly provide additional service to our clientele”.

“We have other types of collaboration –Nicola Pedrotti adds –, such as the tool spare parts via the Internet for TWT systems. The spare parts digital management service is very useful. We sell a client tool systems that have all their spare parts. The client must replace them periodically and the system informs the client precisely which spare parts are needed and practically sends the order, handling it within the system while providing other useful functions too.

The software involved is a multiple level version of Archimede, designed together with us and that practically gives us the chance to design the windows tailored to the client, to change the dimensions of the windows saved in the library, to change the designs of the ashlar panels and to print out the cutting list for production. It handles everything, and basically with one click it sends us the order”.

“It is also important to mention that the QR code is on the tool –Filippo Pellitteri points out.It is not so important to have it on the spare part because the list of spare parts is generated starting from the tool. This is an especially interesting element for window and door manufacturers”.

In which segments will TWT’s business develop, in addition to the window and door sector, based on current prospects and the observatory of an international player?

“We are much too attached to the window and door sector and we will continue working in this direction, also because at this time the market is requiring an increasingly specialised company”.
