ECO-Risers for superfine component geometries


GTP Schäfer has developed the ECO Riser concept, first presented at GIFA 2011, in close cooperation with Mr. Thomas Baginski of Georg Fischer GmbH, Leipzig. The ECO Riser delivers a far higher percentage of its energy to the melt compared to traditional risers. This means that the exothermic energy is focused on maintaining liquid risers for longer instead of losing it unused to the surrounding moulding sand, enabling reductions is riser modulus and greater flexibility in use.

Precisely defined breaking edges for easy riser removal


GTP Schaefer: Many foundries, especially those producing components with a high dimensional accuracy, know the problem: Riser rests cannot be easily and precisely removed from the casting when the riser neck increases above a certain diameter without risking damage to the casting surfaces. Riser expert GTP Schaefer has launched a series of penetration resistant breaker cores, in modules above 5.0 cm, that facilitates easy riser removal by ensuring a clearly defined riser neck.

Environmentally friendly smokeless, inorganic Risers for the non-ferrous metals industry


GTP Schaefer: A common environmental problem occurring in foundries casting aluminium in green sand has been resolved: Traditional use of organic binders for ISO-Riser production leads to high concentrations of smoke and odour during the casting process and subsequent pyrolisation of the riser. In the past inorganically bound risers, used to overcome smoke and fume  issues, have not provided the same performance as risers produced with more traditional organic binders. GTP Schaefer have solved the performance related problems of the past and have launched a new series of inorganic, environmentally friendly ISO-Risers for the non-ferrous sector eliminating smoke and fume, whilst at the same time maintaining the high degree of performance demanded by the end user.

Foundry 4.0: Digitalisation as a key indicator for sustainable business success


In the same way as the invention of the steam engine and the production line a few hundred years ago, digitalisation is fundamentally turning production processes as well our internally and externally-oriented methods upside down nowadays. Industrial success and, as a result, the success of the foundry industry will significantly depend upon the success of improvements in efficiency in terms of data exchange and intercompany communication in forthcoming years. Therefore GTP Schäfer has developed the GTP ToolBox which will support our customers efficiently and especially will simplify and speed up the communication.

GTP Schäfer receives "Preferred Supplier" status from Bosch


As a result of the many years of successful co-operation with the Bosch Rexroth group GTP Schäfer has received the “Preferred Supplier” status. This is the highest possible classification within the Bosch groups’ worldwide network of foundry aid suppliers. As a supplier, GTP Schäfer is tightly integrated into the operational sequences of Bosch Rexroth. This has enabled the development of innovative and efficient logistics concepts as well as the continuous advancement of basic concepts and production stages.



Successful recertification of ISO 9001 and ISO 14001


GTP Schäfer has successfully recertified ISO 9001, originally awarded in 1994 for quality management, and ISO 14001, an environmental certification dating back to 1996. The recertifications were given without objections or restrictions. Since the introduction of the quality management system GTP Schäfer has continually improved and refined their control and production processes. These efforts are an important part of their corporate strategy enabling GTP Schäfer to offer its customers innovative product solutions at the highest possible level of quality.



GTP Schäfer receives class A supplier status from Georg Fischer AG 


Georg Fischer AG has classified GTP Schäfer as a class A supplier in its annual supplier rating. This results from many years of successful cooperation between the two companies. The A rating accords GTP Schäfer the status of a development partner. The relationship has gone from strength to strength in recent years as a result of ongoing joint research and development work by the two companies.



"PX-ME N" riser systems



Hall 3, stand A01


In addition to traditional riser solutions, GTP Schäfer is also presenting the latest developments in the field of exothermic riser systems at GIFA 2007. The ongoing trend towards increasingly more complex and intricately designed castings and foundries’ efforts to realise efficiency and cost benefits call for the rigorous development of established, traditional riser systems.
GTP Schäfer has pressed ahead with the further development of the POINT risers® featuring metal disks (“PX-ME N”) with the aim of offering customers a standard product that incorporates substantial added value in the form of cost and efficiency benefits. These innovative riser systems (photographs 1 to 3) broaden significantly the potential scope of applications for risers, particularly on extremely small or high contact surfaces such as cams. The raised position of the riser prior to moulding on pins enables optimum compacting of the moulding material under the riser. This results in improved process reliability, which constitutes an increasingly important factor in large-scale production in particular.

The risers of the “PX-ME N” series also substantially reduce the necessary scope of work in the cleaning department, thus offering foundries additional cost-cutting potential. The required scope of cleaning work is reduced in particular via the formation of a precisely defined breaking edge by the metal disk directly above the contact surface. GTP Schäfer also offers these risers in fluorine-free quality, in order to reduce the level of fluorine content in the moulding material.

The above-described development of the "PX-ME N" product line with round and oval gate cross-sections demonstrates how GTP Schäfer systematically pursues its corporate strategy of developing innovative and cost-efficient product solutions with and for its customers.

GTP Schäfer presents new moulding material



Hall 3, Stand A01



GTP Schäfer is presenting its new moulding material, CERATEC B, at GIFA 2007. This new development offers an economical alternative to the chromium ore and zircon sand products which are in common use today and to synthetic moulding materials with a low coefficient of expansion.

Apart from the option of adding CERATEC B to quartz sand as a basic moulding material, CERATEC B can also be used in an appropriately high concentration as facing sand and, in particular, in the manufacture of cores designed to withstand high levels of thermal stress.

CERATEC B’s extreme cost efficiency stems from a substantial reduction in the amount of binder required. Depending on the employed binder system, the amount of binder added to the process can be reduced by up to 60% in comparison to the quantities required when using traditional basic moulding materials. In addition to its excellent workability, which results in part from improved castability and reduced bulk density, CERATEC B is also able to increase productivity in the core shop on account of markedly reduced gassing times.

CERATEC B’s high gas permeability and the low binder requirements largely eliminate the need for air cords and core irons. This property of CERATEC B means that casting defects such as gas bubbles, scabbing or sintered core irons can be avoided. Due to its high level of stability when subjected to thermal stress, outstanding surface qualities are attainable even with the most intricate cores. Depending on the employed casting method, these qualities may be comparable with the results of ceramic casting.



Trend towards innovative riser
systems emerging more strongly


Once again this year, GIFA, the world’s largest trade fair for the foundry industry, presented the latest trends in the field of foundry technology. In the area of foundry materials and aids, an increased interest in “value-added” riser systems was apparent among customers.

In addition to the riser sleeve’s original function of supporting the caster in producing shrinkage-free castings, much more is expected of a riser system today, particularly in series production on automatic moulding lines. Foundries’ expectations of modern riser systems focus in particular on cost-cutting coupled with increased process reliability.

Against this background, since the PX-ME riser system was premiered at GIFA 2003 GTP Schäfer has striven continuously to improve the applications engineering of the risers with metal breaker cores, expanding the product range in the process. This riser system enables precision feeding of the ever more intricate castings at the relevant junctions on the tiniest contact surfaces, thus optimising feeding efficiency. The minimal contact surfaces and the controlled predefined breaking point on the cast surface enable a particularly high quality of cast surface, thereby also reducing the attendant cleaning costs.

GTP Schäfer also presented the new VX riser at this year’s GIFA as an addition to the PX-ME riser system. This is a flexible riser system consisting of two pieces which are loosely slotted together, with the pin bringing the two parts of the riser system into position. The distinctive feature of this riser system is the heated riser neck. The VX riser has been developed in particular with small contact surfaces on the casting in mind, such as cams. This principle results in particularly good compacting of the moulding material around the riser neck.

With these riser systems, GTP Schäfer offers customers two ways of addressing the increased complexity of castings. “The onus is clearly on us to offer customers the greatest possible added value with our products," observed senior manager Jürgen Schäfer, who looked back at GIFA 2007 in the most positive terms.
