Wagstaff’s VariMold™ Adjustable Ingot Casting Technology uses the LHC platform in an adjustable mold.  Up to 20 different sizes can be cast though one VariMold, reducing the number of mold sets needed to produce a range of rolling ingot sizes.

The LHC™ Low Head Composite Casting Technology is Wagstaff’s flagship ingot casting product and was developed to maximize ingot quality and casting pit recoveries.

In addition to utilizing production and quality benefits of Split Jet curl reduction technology, LHC molds incorporate a graphite bore into its aluminum mold – a patented technology that is proven to produce premium cast surfaces and ideal metallurgical properties in rolling ingot. This graphite bore serves as a reservoir for casting lubricant, using only 3-5% of the normal amount of oil consumed in conventional direct chill casting.   The graphite bore is also replaceable which significantly extends the life of the mold.

Ingots produced by the LHC process have minimal butt curl and very small shell zones, resulting in superior surfaces and high recovery rates.  The high quality of ingots produced with LHC molds yield significant savings in downstream scalping and edge trimming operations.                   

Benefits of VariMold Ingot Casting Technology

In addition to the stated benefits of LHC Ingot Casting Technology the VariMold Adjustable Ingot Casting Technology provides the following benefits:

• Can be designed to utilize different ends without replacing the rolling faces
• Reduced number of mold sets
• Up to 20 different sizes can be cast through one VariMold
• Reduced hotline side trim
