compact 2/2017 innovation at a glance flexibility, opportunities, innovations new applications for silicone moulded parts silicone masking for high technology coating processes new collaboration with terolab surface gmbh (tls), langenfeld a new field for silicone mouldings is the production of perfectly matched systems for high-tech coatings of components – this describes the new partnership with tls. ›› continuation of this feature inside the items presented in the last biw newsletters from the field of moulded parts were focused on keywords such as project management, tech- nical application consulting and the strong development of the silicone mouldings division. at present, the company also needs to focus on various sales markets in addition to its strategic focus. moulded solutions for the areas of au- tomotive, sanitary, household, electrical, medical and phar- maceutical technology as well as other common indus- tries are already well-known. editorial dear partners and friends of biw, the markets are more dynamic now than they have been for many years. the economy is ticking over, raw materials are becoming scarce, commodity prices are rising internationally, and competition is also increasing, so that family-run small and medium-sized businesses are finding themselves struggling in the "sandwich position" between large-scale industries, oems and wholesale trade on the one hand and chemical groups on the other. these companies achieve greater success as their solutions become more specialised and their products more individualised, which small and medium-sized companies develop for ever more demanding clientele and bring to the point where they are ready for series production. service, consulting, product development and application-specific solutions are the path to success. the foundation for this recipe for success is a well- trained and motivated team of employees. the number of jubilarians, completed advanced train- ing programs and new trainees shows that biw is meeting the challenges and investing according- ly – in the headquarters in ennepetal, but also in the associated companies of the growing silicone group. ralf stoffels dr. markus wiethoff lutz stoffels the emphasis of tls surface gmbh is on coatings for mechanical engineering 01
compact view of the tls manufacturing procedure ›› continuation of the cover feature the terolab surface group is one of the leading experts in the field of surface coatings. customers of the internationally operating company include compa- nies from the fields of mechanical engineering, aviation technology, power generation, agriculture, food and textile industries. tls is also active in the areas of anilox roll production and laser engraving. at the same time, tls operates in the highly sensitive area of biomedical implants. the company's roots are in switzerland. the holding com- pany and the management company are headquartered in lausanne. there are two locations in germany and another branch in france. the aim of the group of companies is to achieve a considerable positive effect on public welfare as well as on the environment through its business activities. in 2016 tls sought a suitable partner for the production of individual moulding solutions – from small batches to batches of a few thousand. due to the wide range of capabilities and support in pro- ject management, design and engineering, it was very clear that biw would be a suitable partner for long-term cooperation. 02 an advantage in the design of the components is the flexibility of biw – due to its own design of the articles and the development of a modular tool concept. within the scope of the mould prov- ing, it was possible to implement adjustments quickly and in a targeted manner. the result is remarkable. with biw as a supplier, tls sees a long-term partner for various questions in the field of silicone processing. the future lies in silicone as a material which offers a very great advantage for process optimisation. the articles can be reused to some extent. the masks are replaced by the user depending on the degree of wear. depending on the requirements for the product, silicone masks are manufactured using lsr or htv injection moulds. all tls projects are designed by biw and ulti- form-fitting silicone masking for blasting and coating mately produced in-house by the biw tool manufacturing department. the first prototypes were assessed and evaluated together with the customer at biw competence center mouldings. biw competence-center mouldings implements technically and economically efficient projects with special challenges. contact us if you have a suitable application! we look forward to your inquiry. — sven braatz the components are usually masked manually with the aid of spe- cial adhesive tapes and mould trays for protection during corundum blasting and coating. the time savings attributable to the use of silicone moulded parts are more than 50 % in some cases. dr. thorsten stoltenhoff authorised officer and head of r & d terolab surface gmbh www.terolabsurface.com
welcome to the team, dr. rer. nat. daniel siebler "smart" materials silicone changes colour due to temperature influences the colour change of coloured silicone is realised by thermochromic colour pigments. a reversible molecular structure change occurs in these pigments due to the ex- ternal thermal stimulus, whereby a colour change from coloured to colourless can be observed. more complex two-colour changes can also be realised by combining the colours yellow, magenta and light blue – with up to 3 colour variations. the temperature window of the colour changeover is also variable, irrespective of the currently available nine ad- justable colour shades. it should be noted that the colour change does not take place in a sudden manner, but over a temperature interval of approx. 2–10 k. together with you, we would like to develop systems adapted to your requirements and applications. temperature window colour shading standard –15 ºc 31 ºc 65 ºc orange red light blue violet — dr. daniel siebler –50 ºc 0 ºc 50 ºc 100 ºc 150 ºc yellow magenta green blue black position deputy chief of development training doctorate in chemistry objectives at the biw the development of silicone with im- proved properties and new functionalities biw insulation and sealing technology (kunshan) co., ltd. with the founding of biw insulation and sealing technology (kunshan) co., ltd., biw isolierstoffe gmbh once again expanded its business areas internationally in 2014 under the umbrella of the silicone group. the chinese-based independent company is developing very well. the excellent international cooperation is also to be highlighted. the openness, friendliness and willingness to help all have made the whole group a team. the whole group enjoyed a game of basketball during lunch break despite the tropical temperatures. a weekend visit to the huge city of shanghai accompanied by the chinese colleagues rounded off the program. — lutz stoffels the international team is thus working to expand the product and customer portfolio. there is an intercultural and collegial exchange in close collaboration. during a visit to biw insulation and sealing technology (kunshan) co., ltd. by a four-person group consisting of developers and technicians, the foundations for further development were laid on site. employees got to know each other per- sonally and worked together on the development of biw kunshan.
