EXACTCAST riser sleeves and auxiliary products are available in a wide variety of shapes and formulations. The basic shapes include: cylindrical, insertable, neckdown, mini-riser, floating coverlid and pouring cup designs. In addition to the traditional mini-riser design, a new RC series mini-riser design is available which offers reduced riser sleeve contacts that facilitate easier removal of the risers from the castings.

EXACTCAST Styles:
• Cylindrical
• Insertable
• Neckdown
• Mini-Riser
• Floating Coverlid (not available in Europe)
• Pouring Cup (not available in Europe)

EXACTCAST Cylindrical Sleeves

EXACTCAST cylindrical sleeves are used primarily in open riser applications. They are available in both insulating and exothermic/insulating formulations.

Advantages of EXACTCAST Cylindrical Sleeves:
• Dimensional accuracy
• Improved productivity
• Consistent thermal properties and performance
• Also made from low density, non-fibrous insulating materials

EXACTCAST Insertable Sleeves

ASK Chemicals insertable riser sleeves are produced using ASK Chemical’s patented cold box process or with inorganic silicate binders. They are dimensionally accurate and high performing. Available in several formulations (insulating, exothermic and fluorine-free) our riser sleeves are sure to meet your metal casting needs. EXACTCAST insertable sleeves are also non-fibrous. Therefore, screen plugging during reclamation is of no concern. Moreover, due to its non-fibrous makeup potential defects such as, deformation, spring back and inconsistent performance are eliminated.

Advantages of EXACTCAST Insertable Sleeves:
• Dimensional accuracy
• Increases productivity
• Low gas evolution
• Consistent thermal properties and performance
• Also made from low density, non-fibrous insulating materials
• Available in custom shapes and sizes for a multitude of applications

EXACTCAST Neckdown Sleeves

ASK Chemicals EXACTCAST neckdown sleeves are used primarily in open riser applications. They are available in both insulating and exothermic insulating formulations.

Advantages of EXACTCAST neckdown Sleeves:
• Reduced contact area
• Dimensional accuracy
• Improved productivity
• Consistent thermal properties and performance
• Also made from low density, non-fibrous insulating materials

EXACTCAST Floating Cover Lids (not available in Europe)

EXACTCAST floating cover lids replace the need to apply the typical powdered hot topping to open risers. They are much more consistent in performance than standard hot toppings due to the predetermined size and weight of the cover lid. The thickness of the lid is designed in proportion to the diameter of the riser. They are typically placed inside the feeder when the mold is closed and float up as the riser fills the molten metal. Floating cover lids are available in insulating / exothermic formulations

Advantages of EXACTCAST Cover Lids:
• Improved feeding consistency & performance
• Sized specifically for the riser – eliminates waste
• Reduced segregation
• Improved workplace safety
• Cover lids can be manually modified in a blind riser
• Cover lids help improve casting yield (due to shortness of blind riser)

EXACTCAST Pouring Cup (not available in Europe)

EXACTCAST pouring cups are used in direct pouring applications, promoting directional solidification and increasing metal cleanliness. Containing high quality ASK Chemicals’ filters, they are available for use in aluminum, grey iron, ductile iron and steel applications. They are also available in sizes ranging from 2” to 7” diameter.

Advantages of EXACTCAST Pouring Cup:
• Improved productivity
• Improved casting yield
• Improved metal cleanliness
• Promotes directional solidification
