Company History
To be a leading international supplier of technical solutions for noise, vibration and shock isolation.
1988 – Lennart Söderman, Kjell Johnsson och Carl Sejersted Bödtker startar Vibratec Isolation AB i Stockholm. Företaget ägnar sig främst åt lösningar i helmetall för marina tillämpningar tack vare Lennart Södermans erfarenhet och expertis som skeppskonstruktör.
1990 – Vibratec Isolation AB flyttar till Blidö, en ö i norra delen av Stockholms skärgård. Företaget har tre anställda och är inrymt i BIHABs (Blidö Industrihus) lokaler. Under åren som följer påbörjar företaget sin egen tillverkning av fjäderisolatorer och rörhållare och inleder också sitt första offshore-projekt med specialutvecklade vibrationsdämpande infästningar med fjädrar.
1998 – Fastighetsföretaget BIHAB förvärvas och Vibratec Isolation AB övertar anläggningens kontorslokaler, verkstad och lager.
1999 – Vibratec Isolation AB förvärvar Maskinverkstaden Wannerstens Mekaniska eftersom ambitionen är att öka företagets egen produktion av vibrationsisolatorer. Dessutom köper bolaget 51 % av det konkurrerande företaget Akustikprodukter AB, där det norska dotterbolaget APN ingår. Förvärven breddar Vibratecs produktutbud till att omfatta även ljuddämpare, wire-isolatorer och gummiprodukter. I samband med att företagen slås ihop ändras namnet till Vibratec Akustikprodukter AB (och till Vibratec Akustikprodukter AS i Norge).
2001 – Bolagets kreativa grundare Lennart Söderman avlider tragiskt i ALS. Hans medgrundare Kjell Johansson tar över VD-posten.
2003 – Företaget har haft en stark utveckling och blir ett Gazelleföretag. Ett litet agentnätverk växer fram. Rickvin Trading Pte i Singapore blir den första agenten.
2004 – Vibratec stärker sin position som ett ledande teknikföretag genom att välja in Leif Kari, som är professor i teknisk akustik vid Kungliga Tekniska Högskolan (KTH), i bolagsstyrelsen. Det samarbete med Marcus Wallenberglaboratoriet för ljud- och vibrationsforskning vid KTH som det här tillskottet medför ger Vibratec en unik position mellan industri och spjutspetsforskning.
2005 – Vibratec Akustikprodukter blir ett registrerat varumärke i Sverige, Norge och Kina.
2006 – Moderbolaget blir certifierat enligt ISO:9001:2000.
2007 – Ett nytt dotterbolag etableras i Estland: Akustikatooted OÜ.
2008 – Ett nytt dotterbolag etableras i Danmark: Vibratec Akustikprodukter ApS, med Anders Olsen som VD. Svante Hägerstrand blir ny VD för Vibratec Akustikprodukter AB.
2009 – Återstående 49 % av det norska dotterbolaget Vibratec Akustikprodukter AS förvärvas.
2011 – Produktionen av wire-isolatorer flyttas från Norge till Sverige – all produktion sker nu under samma tak.
2014 – 5 personer går säkerhetskurs för offshore Vibratec börjar gör mätuppdrag och installationer på riggar och plattformar i Nordsjön.
2016 – Moderbolaget blir certifierat enligt ISO:14001:2015. Tidigare kvalitetscertifiering uppdateras till ISO9001:2015.
2017 – Ett nytt dotterbolaget Vibratec Installation AB etableras. Bolaget gör f.a. installationer av flytande golv och rum-i-rummet-lösningar.
2018 – Dotterbolaget 3DI Akustiikkatuotteet OY etableras i Finland.

Support
Vibratec has an extensive experience, combined with the use of modern tools, when we design and manufacture tailor made solutions in all areas of vibration and noise reduction. Vibratec performs test to evaluate mechanical, physical and long term behaviour on materials as well as complete solutions.
Installation
We can also offer installation on site of many of our products. This ensures correct installation and minimise the risk of performance loss due to lack of experience or the “human factor”. Normally we limit our undertaking to installation of our products and systems, ie installation of gypsum board, mineral wool, reinforcement bars or casting of concrete is not done.
Typical installations offered:
• Floating floor systems, both light weight and heavy (concrete)
• Machine foundations
• Inner ceiling systems
• Building base isolation systems
• Ballast mats and slab track beds
• Q-track systems
• Tuned mass dampers (tuning of mass and stiffness)
Production
Vibratec has its own production and assembly facilities on Blidö, Sweden. This is where we produce our all-metal marine and offshore isolators, spring packages and wire rope isolators. By having our own manufacturing we are able to take on customised products and special designs. Our equipment consists of high speed turning centres, 2 vertical milling CNC machines, 2 lathes, steel band saws, cranes, presses, grinding machine, TIG and MIG welds, industrial steel washing machine and painting box.
We work with LEAN and we strive for constant improvements of the work environment and efficiency.
Metal scrap is separated into aluminium, steel and stainless to simplify recycling and burnable waste is sent to closest possible incineration only 2 km away
