Plastic injection molding with all common thermoplastics as well as high-performance and bioplastics
SKT has been manufacturing plastic injection molded parts for half a century. This makes us one of the most experienced specialists in plastic injection molding. Our range of services includes conventional injection molding, overmolding and insert- & outsert-molding. We only use high-quality injection molding machines, such as ENGEL and ARBURG, and all common materials and additives are possible. Custom-made products and small series are just as welcome as large series.
