KALMIN 5251 NF
Insulating Sleeves for Magnesium Foundries
KALMIN 5251NF riser sleeves are low-density, tube sleeves made of insulating refractory material. They are specifically formulated with inhibitor and designed to promote efficient feeding of sand cast Magnesium castings.
The insulation value of KALMIN 5251NF delays solidification, keeping metal in the riser liquid longer.
Benefits:
• Sleeve withstands handling and molding
• Increased casting yield
• Reduced metal treatment costs
• Reduced riser contact area
• Reduced casting cleaning costs
• Sleeves are easily cut to special heights
Many magnesium foundries also cast aluminum and successfully use KALMIN 5251 NF sleeves throughout the foundry, thereby preventing operational cross-use errors.
Copper/Brass/Bronze Foundries
Low temperature copper/brass/bronze foundries can use TEMPGARD insulating sleeves.
Higher temperature copper/brass/bronze foundries will find that KALMIN 70 insulating sleeves are more suitable for their refractory requirements.
TEMPGARD
Insulating Sleeves for Non-Ferrous Foundries
TEMPGARD riser sleeves are strong, low-density, tube sleeves of insulating refractory material. They are specifically designed to promote efficient feeding of sandcast aluminum and copper castings.
The excellent insulation value of TEMPGARD delays solidification, keeping metal in the riser liquid longer. This allows smaller insulated risers to replace larger conventional sand-lined risers.
Benefits
• Sleeve withstands rough handling and molding
• Increased casting yield
• Reduced metal treatment costs
• Reduced riser contact area
• Reduced casting cleaning costs
• Low smoke and fume
• Sleeves are easily cut to special heights
KALMIN 70 riser sleeves
KALMIN 70 riser sleeves are highly efficient insulating riser sleeves
KALMIN 70 riser sleeves are insulating, lightweight riser sleeves used to efficiently feed copper castings. They are highly heat resistant and provide superior insulating characteristics. The use of riser sleeves increases casting yield by allowing smaller riser sizes than conventional sand risers and reduces cleaning costs.
KALMIN 70 Round Neckdown Sleeves further reduce the riser casting contact size, minimizing the need for breaker cores. Also, risers can be located on a smaller area which can reduce or eliminate metal padding.
"Prior to our relationship with Weaver Materiel, we were purchasing riser sleeves direct from the OEM. As a stocking distributor, Weaver typically is able to deliver same or next day. OEM lead times averaged three to four weeks. With Weaver, I've been able to reduce my working inventory by about 40%."
