The EXACTCAST mini-riser – the formula for success

One crucial factor affecting the productivity of a foundry is the fettling needed on the finished cast part. EXACTCAST™ mini-risers, which offer here clear advantages over natural sand and exothermic feeder caps.

 

Mini-risers for standard applications

High-performance, versatile mini-risers for ideal results

 

EXACTCAST ADS

The ADS riser is a high-stability solution suitable for No-Bake and hand-mold applications. ADS risers are free of fluorine. The riser can also be fitted with an open spring pin for use on automated green sand molding lines.

Benefits

- Low emissions

- Available fluorine-free

- Reduced molten iron content for improved yield

 

EXACTCAST KMV

The KMV mini-riser is a particularly low-weight solution for use with a range of molding types. This versatile riser can be fitted with a spring pin or simply placed directly on the casting. The KMV is a highly exothermic solution available in a fluorinefree formulation.

Benefits

- Low weight

- Reduced molten iron content for improved discharge

- Optimized yield for steel casting

 

Mini-risers with metal neck

Breaker cores are no longer needed

 

The BKS water glass bonded mini-risers and the organically bonded, lightweight KVM-QM make use of a loose metal neck in the bottom part of the riser and the corresponding spring pin. These provide a specially defined breaking point that makes it easier to detach the feeder. Fettling costs are reduced considerably as a result. In some cases, there is no need at all for rework. The BKS C mini-riser featuring a centering hole is designed for use on a rigid pin. Both variants are available in a fluorine-free formulation.

 

Benefits

- No breaker cores needed

- Extremely small contact areas to the casting

- No contact between mold section and exothermic feeder material

- A range of variants for your processes

 

Mini-risers for automated high-pressure molding machines

Dynamic mini-riser system with reduced riser neck diameter

 

EXACTCAST FDS

FDS risers are used with spring mandrels, reducing greatly their fitting surfaces. In addition, they do not directly contact the casting. They are available fluorine-free.

Benefits

- Low emissions

- Reduced riser neck diameter for reduced fettling costs

- The spring pin helps reduce contact areas, surface defects, and pattern wear

 

EXACTCAST KMV-QT

KMV-QT is a Cold Box bonded, cost-effective, lightweight feeder that is used with spring pins for minimized contact areas. The riser can also be used directly on the casting. They are available fluorine-free.

Benefits

- Low weight

- Reduced riser neck diameter for reduced fettling costs

- Plastic caps eliminate feeder inclusions on the mold surface

 

Mini-risers with freely moving metal neck

The most efficient and effective mini-risers

 

EXACTCAST Optima KL and EXACTCAST Optima KMV-CC

The EXACTCAST OPTIMA risers offers all the advantages of the BKS and KMV risers with a loose integrated metal neck in the bottom part of the riser and the corresponding pin. These act as a precisely defined breaking point. In addition to the benefits provided by the BKS and KVM-QM feeder, the virtually frictionless sleeve and the integrated riser cap prevent crumbling particles from falling into the mold. Both variants are available fluorine-free.

Benefits

- No breaker cores needed

- Extremely small contact areas

- No contact between mold section and exothermic riser material

- A range of variants for your applications

- Riser particles are prevented from falling into the mold

- A 100 % inorganic variant of the OPTIMA KL riser with metal cover is available on request.

 

Riser caps with the efficiency of mini-risers

Improved discharge with feeder caps

 

EXACTCAST KIM insertable and EXACTCAST KIM-QM

The new, insertable mini-riser series EXACTCAST KIM was developed for customers seeking to reduce their circulating material and hence the associated costs. The solution is the KIM risers, which exhibit double the wall thickness of conventional riser caps, and so require less metal as a result. Thanks to the special combination of its material, this riser exhibits a very low overall weight. Available in a fluorine-free formulation, with or without breaker core, or with a reduced metal riser neck diameter.

Benefits

- Improved yield

- Additionally high insulating effect

- Available in a range of sizes

 

Riser sleeves for open riser applications

Precision designs for a range of applications

 

EXACTCAST neck-down risers

ASK Chemicals EXACTCAST neck-down risers are designed primarily for open riser applications. They are available in insulating and exothermic /insulating formulations. They are also available with a tapered geometry and fluorine-free, with or without breaker core.

Benefits

- Smaller contact area

- Dimensional accuracy

- Constant thermal properties and performance

 

Insertable riser caps and sleeves

Excellent dimensional accuracy

 

Riser caps and sleeves are available in highly exothermic and insulating designs. They are characterized by high strength and dimensional accuracy. They are suitable for inserting into molds and automated molding lines with core setters. They can also be used together with breaker cores and are available fluorine-free, with or without breaker core.

Benefits

- Low gassing

- Constant thermal properties and performance

- Suitable for use with breaker core
