Empresas Polar C.A. is the largest Venezuelan food and beverages corporation managing three main businesses/brands: Polar Brewery, Polar Foods, and PepsiCo Venezuela. Role: Internal consultant and technical support in materials engineering (metals, ceramics, and polymers) for 14 production facilities Nationwide of the Beverage Division. Collaboration with other core Departments.• Managed the failure analysis of cast iron-based roller of a Huppmann milling machine for barley process. Final technical report indicated a factory defect. No cost for part replacement.• Extended the useful span life of cast iron rollers for barley milling by 40 %, applying tungsten carbide coating by high velocity oxygen fuel process. • Led new lean lubrication plan in the Canning and Bottling Department, resulting in an increase of efficiency of 30 % and effectiveness of the lubricant usage. • Managed the restauration of main gear of bottle filler machine by lock & stich. Developed the procedure to restore similar gears across other production plants. • Determined the nature of stainless-steel blades degradation damage of a Siemens steam turbine Model G300-2V5, by powder X-ray diffraction. Improved boilers operations.• Detected microbiologically influenced corrosion in a steel tank for water storage by visual inspection and powder X-ray diffraction. Managed tank restoration by ASME and API standards.• Led reverse engineering investigation by FTIR and development of polymeric guides of false flooring of product pasteurizers, resulting in local fabrication to avoid imports.
