Our products

Product category: Feeder sleeves

THERMO risers

THERMO-risers are thick-walled risers which enable feed metal utilisation of up to 60-70%. The properties of the solid riser wall range from highly exothermic to highly insulating, according to the intended application. The optimised material properties and the adapted volume enable substantial improvements in output and economic efficiency. A modulus range between 0.8 cm and around 8 cm can be covered with risers from this product segment.

POINT risers

POINT risers® are thick-walled risers which enable feed metal utilisation of up to 60-70%. They have been developed especially for demanding applications in modern high-pressure moulding lines. The properties of the solid riser wall range from highly exothermic to highly insulating, according to the intended application. The optimised material properties and the adapted volume enable substantial improvements in output and economic efficiency.

ECO risers

Energy efficiency in the riser system
With respect to performance and competitiveness, foundries and their supplier industries cannot turn their backs on the global trend to use resources more efficiently and to optimize raw materials and auxiliary resources. Great potentials can be found in the field of energy efficiency in the context of energy intensity of production processes in foundries. In addition to melting, additional energy is needed and accordingly supplied at various points in the production process. The riser system is one of the main points in the process where extra energy is added. Nowadays, solidification control is achieved primarily with exothermic feeder sleeves that are used for point heating of the feeder metal, thus enabling feeding relevant nodes of the cast part. Here, the exothermic reaction of the feeder material adds extra energy to the process while additional liquid metal is kept ready in the riser system for feeding.

About us

Company details

GTP Schäfer GmbH is one of Europe’s leading manufacturers of exothermic and insulating risers in Europe.

We develop and manufacture our products for the European foundry industry at our company headquarters in Grevenbroich (between Cologne and Düsseldorf). Ever since the company was founded in 1988, we have rigorously pursued the ongoing development of our innovative product portfolio and our production engineering in order to offer our customers the broadest possible spectrum of solutions geared to the industry’s practical needs. Our portfolio comprises several hundred types of risers covering a broad scope of modulus and applications. GTP Schäfer deploys a 3-shift production system, manufacturing its high-quality riser systems with a workforce of around 80. Our customers include iron and steel foundries with automatic moulding machines or hand moulding shops.
