Ingot Sawing System
UTEC Industrial engineered a custom ingot sawing system for Kaiser Aluminum, delivering precise cuts that meet strict industry standards with custom PLC controls and heat-treated key components.
Project Overview
Aluminum ingots cast at processing plants must be sawn to precise dimensions before they can proceed to rolling, extrusion, or other downstream operations. The sawing process demands accuracy — cuts must meet strict dimensional tolerances and surface finish requirements while handling ingots that can weigh thousands of pounds. Any deviation from specification results in scrap material and production delays.
UTEC Industrial designed and built a custom ingot sawing system for Kaiser Aluminum that automates the sawing process with precision-controlled blade positioning and feed rates. The system handles the full cycle of ingot clamping, positioning, sawing, and offloading, reducing cycle times while maintaining consistent cut quality across thousands of production runs.
The sawing system operates in the demanding environment of an aluminum processing plant, where heavy loads, metal chips, coolant, and continuous operation create extreme wear conditions. UTEC addressed these challenges through robust mechanical design and heat-treated components that maintain their performance over extended service life.
UTEC's Role
UTEC engineered the sawing system from concept through commissioning, handling mechanical design, CNC machining of precision components, fabrication of the structural frame and material handling subsystems, and development of the control software. Key wear components — including guide rails, clamping surfaces, and blade mounting assemblies — were heat treated in UTEC's on-site car-bottom furnace at temperatures up to 1,800 °F to achieve the hardness and wear resistance needed for continuous production use.
UTEC's controls engineers developed custom PLC and motion control software that manages blade speed, feed rate, and positioning based on the specific ingot size and alloy being processed. The software includes automated sequencing for the complete sawing cycle and integrates with Kaiser Aluminum's plant-wide production management systems for scheduling and quality data tracking.
