Wagstaff® APEX™ Rolling Ingot Casting Technology incorporates a fully automated, fully adjustable mold that all but eliminates ingot butt swell. Butt swell is increased thickness in the ingot’s butt region caused by casting with fixed molds. When casting speeds are outside of the mold’s specifications, the ingot’s finished shape will not be as flat as expected. Butt swell is waste which needs to be removed by scalping prior to rolling. Pit recoveries improve through minimal butt swell scalp when casting with APEX Ingot Casting Technology.

Using Wagstaff’s sophisticated, patented, recipe-controlled mold bore flexing throughout the cast tightly controls the ingot shape. APEX allows for ingot shape optimization for nearly all alloy and speed combinations while casting flatter ingots. The APEX mold bore shape is configured to meet optimum cast speed and alloy requirements, whereas most mold bores are designed to meet slower cast speeds to reduce butt swell. Cast speeds can be increased by 25% with APEX Ingot Casting Technology.
APEX technology allows for quick mold size changes. Move the end faces to change the ingot width, swap in new end faces to change the ingot thickness. The APEX casting system also allows for changes to thicknesses, widths, and mold bore flex recipes in minutes, as opposed to the several weeks it takes for a new mold to be designed and delivered. APEX also accommodates for size, alloy, and speed changes while still producing a flatter ingot than those created in a fixed mold. New ingot size orders can begin in hours, as opposed to several months.
APEX provides sustainability benefits with the reduced resources required in manufacturing an efficient, multi-size casting station.
