Process Fundamentals
PET preforms, blow-molding fundamentals, equipment parameters and changeover procedures.
Training & Continuous ImprovementBuild the Knowledge.
Build the Knowledge.
Control the Process.
Improve the Results.
Hands-on PET manufacturing training meets advanced process science. D.E.L.L. PET and strategic technical partner Steve Zagarola of NWCPE help manufacturing teams understand their processes, solve complex problems, and sustain improvements.
Training built around your operation
Build capability where it matters: on your production floor.
Structured Troubleshooting
Connect symptoms with production evidence and turn recurring issues into deeper process knowledge.
Continuous Improvement
Review data, validate changes, document learning and hold the gains over time.

Some people study an industry. Others help create it.
Steve helped develop the first PET bottle designs at The Coca-Cola Company, is an inventor on the first commercial 2-liter PET bottle patent, and authored Coca-Cola’s original PET performance specifications and test methods.
Through the D.E.L.L. PET and NWCPE strategic partnership, manufacturers can access his foundational PET knowledge and specialized DOE, SPC, quality system and technical coaching capabilities.
- Foundational PET development
- DOE + SPC expertise
- Lean Six Sigma
- Plant-floor training
Optimize · Control · Sustain
Two powerful disciplines. One stronger process.
DOE identifies factors and interactions that drive performance. SPC helps teams understand variation and maintain control.
Discover what drives performance.
DOE is a structured statistical method for understanding and improving processes. By systematically varying key process variables, DOE identifies the factors and interactions that drive performance and produces predictive models.
These models accelerate startup optimization, solve complex problems, and improve yield and quality. The practice of DOE fosters collaboration among operators, technicians, and engineers, building process knowledge, teamwork, creating a sense of ownership and pride in sustainable results.
