Dörentrup was founded in 1901 and was one of the pioneers in the manufacturing of refractory products for the foundry industry in Germany. Our company philosophy, which builds on innovations and customers, has remained unchanged and is as successful as ever. We produce fire resistant lining for melting, holding, pouring, transport, and treatment furnaces:
- Refractory materials
- Pre-fabricated, ready-to-install modules
- Ready-to-use, highly economical pre fabricated
- Dorit-crucibles.
- Mica products and insulation
…Knowledge and a variety of services.
Traditionally, we specialise in refractory products for the coreless induction furnace, but we also provide convincing solutions and systems for other foundry equipments such as channel induction and cupola furnaces.In addition, our product range includes powerful lining tools (e.g. automatic vibrators and entire vibrator systems) and sophisticated processing techniques. They support our customers in achieving optimal lining, quick start up, as well as an effective and economical operation of the furnaces. Our service portfolio also includes the assembly of entire plants.
Co-operating to achieve optimal results.
Our excellent technical service, constant high-quality products, speed, reliability and individualised, economical services, even for our smaller customers, are the reasons why we are the market leader in Germany.
