Laboratory Testing: Experience interpreting test data from tensile, elongation, modulus, rheometer, mooney viscosity, and other property testing to solve processing problems.

Compounding: Can recognize a Banbury mixing problem with implementation of a solution to ensure the manufacture of a prime quality component for downstream processing.

Processing: Issuance of specifications in order to process woven fabric (polyester; nylon) single-end core, steel cord, and gum components for tires. This includes calendaring, steelastic, roller head, and extrusion equipment.

Supplier Qualification: Perform evaluations to quality suppliers of steel cord, beadwire, fabric cord, polyethylene film, polymers (natural rubber; halobutyl SBR), and chemicals, such as carbon black, oils, resins, etc. Also, qualifications of cooling water micro-biocides have been performed.

Extrusion Cooling Water: Develop and maintain specifications for extrusion cooling water (contact with rubber) in relation to temperature, m-Alkalinity, calcium hardness, pH, and clarity.

Curing (Vulcanization): Perform (thermocouple) testing to determine the cure-step procedure. Troubleshoot internal/external valve, boiler, and system problems resulting in tire anomalies.

Quality Assurance: Issued statistical analysis on data collected in various aspects of tire manufacturing. Served as TS 16949 (ISO) coordinator in department, which involves issuance of Work Instructions for processes. Introduced a “Steel Cord Supplier” rating program, which provided a tool to Purchasing to prioritize multiple suppliers of a particular construction.
