Founded in Hamburg in 1919, WISKA develops and produces innovative products for customers worldwide. Over 210 employees work at two locations in Kaltenkirchen, our company´s headquarters and 260 world wide.
Our cable glands are used around the globe and characterised by flexible applications in diverse areas of industry as well as highest quality standards. For the maritime industry, we are a 'single source' supplier of lighting and electrical installation equipment. Every day again, our products prove their efficiency, even under the most adverse conditions. Our VARITAIN range is one of the most innovative reefer container sockets worldwide. With our CCTV technology, WISKA sets worldwide standards in terms of camera surveillance.
In order to deliver highest quality, we control every process of the entire supply chain ourselves. Research and development, material selection and purchasing, construction and manufacturing, testing and test methods, consulting, sales, marketing, logistics, after-sales service – everything is in our hands and is controlled by strict quality management.
Because of increasing demand, we are constantly expanding our production capacity. Several new injection-moulding machines have recently been purchased, thereby increasing our machinery in Kaltenkirchen to well over 30 units. These are supplemented by additional assembly areas and storage capacities.
Proximity to customers and on-site support are very important to us. A global network of sales partners and subsidiaries in China, the UK, India, Paraguay and Spain are now part of the WISKA family.
At WISKA, not only are our products a priority but we also take our social responsibility seriously. We are committed to the ZVEI (German Electrical and Electronic Manufacturers’ Association) Code of Conduct and thus to achieving a common understanding of ethical values in relation to working conditions, social and environmental sustainability, transparency, and trustful cooperation. These values form the basis of how we collaborate daily with all business partners.
