Die Polisher/Corrector – Aluminum Extrusion
Job Summary
The Die Polisher/Corrector inspects, repairs, and maintains the extrusion dies used to shape aluminum profiles. Working in the die shop, this role collaborates with supervisors, press operators, and quality-control teams to diagnose and resolve die-performance issues. Technical expertise, precision, and a strong understanding of the aluminum extrusion process are essential to maximizing die life and maintaining production efficiency.
Essential Duties and Responsibilities
Die Analysis and Correction
-
Inspect samples of extruded aluminum to diagnose dimensional inaccuracies, flow inconsistencies, and surface defects.
-
Use precision measuring instruments (calipers, micrometers, gauges) and accurately read and interpret results to verify die dimensions against design specifications.
-
Determine and perform the repairs or modifications needed to restore dies to specifications.
Die Maintenance and Repair
-
Correct and polish die bearings, feeder plates, and other tooling surfaces using hand tools and pneumatic grinders to improve metal flow.
-
Perform routine maintenance, including caustic cleaning to remove aluminum buildup and nitriding to increase die hardness.
-
Disassemble and reassemble multi-part die assemblies.
-
Inspect tooling for stress cracks, excessive wear, or damage and carry out necessary repairs.
Data and Process Management
-
Document die corrections and maintenance history in the plant’s computer system.
-
Partner with press operators and managers to troubleshoot die problems during production.
-
Communicate recommendations for improvements or design changes for future dies.
Safety and Equipment
-
Operate and maintain die-shop equipment such as mills, sandblasters, and caustic systems.
-
Safely operate forklifts and other material-handling equipment to move dies to and from the press line.
-
Follow all company safety policies and procedures, especially when working with hand tools, heavy equipment, and caustic chemicals.
Qualifications
Education
-
High school diploma or GED required.
-
Technical training or an associate degree in manufacturing or a related field is a plus.
Experience
-
Several years of hands-on experience in die correction and polishing within the aluminum extrusion industry preferred.
-
Advanced roles typically require 5+ years of experience.
Skills
-
Strong mechanical aptitude and problem-solving skills.
-
Ability to read and interpret blueprints and technical drawings.
-
Proficient in both using and correctly reading precision measuring tools (calipers, micrometers, gauges, dial indicators).
-
Knowledge of metallurgy and metal flow dynamics.
-
High attention to detail and ability to perform precise work.
-
Effective communication and teamwork skills.
-
Forklift certification or ability to become certified preferred.
Physical Demands
-
Ability to lift up to 75 pounds.
-
Stamina for extended standing, walking, bending, and kneeling.
-
Comfort working in a manufacturing environment with moving mechanical parts, varying temperatures, and high noise levels.
