Understanding PET Material and the Injection Stretch Blow Molding Process (PET-ISBM)
Goals of this Course:
- Understand the science behind the plastic material
- Learn successful pre-form production
- Evaluate and improve operating procedures
- Recognize processing conditions that affect quality
- Analyze and solve practical PET Injection Stretch blow molding problems
Course Description: Take a deep dive into the complexities of processing PET, a widely used versatile plastic material found in everyday consumer products and more. Learners will secure a solid understanding of the science behind the material, learn successful preform production, and become proficient in the final process involving stretch injection blow molding. Individuals accessing this intensive, two-part online course will gain a thorough understanding of the characteristics of PET and how to efficiently and safely process it.
Recommended For: Machine Operators, Material Handlers, Set-up Personnel, Process Engineers, Production Supervisors, Plant Managers, and Quality Control Personnel
Length: Two Part Course
Language: English (Sub-title capabilities)
Lessons Included:
The first part of the lesson describes the chemical and molecular structure of PET. The description of molecular chains is necessary to understanding the viscosity of the resin. The course covers the importance of the crystallinity of the preform as it transitions from preform to blown bottle. Two types of crystallinity are also described as the preform is heated and blown. This lesson takes a close look at the goals of the blow molding process; to create a bottle with strength, clarity, and uniform consistency.
The second part of the lesson describes the conditions that affect raw materials and includes a detailed description of the injection molding machine conditions that will affect the preform. Plastic temperature, pressure and cooling rate all have
key importance to crystallinity control of the preform. Factors that will help reduce crystallinity formation in the preform are also discussed.
