This hands-on course is an introduction to injection molding for anyone who wants to know how pellets are transformed into the plastic parts we use every day. Students will learn what happens in a molding plant, from opening a new package of material all the way through packaging the final product. Every student will have the opportunity to run an injection molding machine and see the effects of changing machine controls.
By the end of Day 1, students will be able to:
Name the 4 plastic variables
Describe the flow of pellet through a processing plant
Identify the 3 components of the injection molding machine and understand their functions
By the end of Day 2, students will be able to:
Predict how machine controls affect the 4 plastic variables and part quality
Understand why not all polymers can be processed the same way
Explain why the “heat history” of a material affects its processability
By the end of Day 3, students will be able to:
Use the Scientific Method to solve problems
Test machine performance indicators such as linearity and check ring function
Find the root cause of defects such as air bubbles, voids and sink marks
Venue: Polymers Center Campus
The Polymers Center of Excellence is a not-for-profit 501(c)6 organization created by the state of North Carolina to increase knowledge, provide technical support, and assist in the development of emerging technologies in the plastics industry.
The Polymer Center was founded in 1972 when the State of North Carolina funded plastics specialists in the Industrial Extension Service program at UNCC. The center, located at that time on the UNCC campus, expanded in 1994 when a joint venture was entered into with NCSU to form PEP (Polymers Extension Program). By 1999, PEP moved off of the UNCC campus and became today’s Polymers Center of Excellence (PCE). In 2012, Polymers Technology Center (PTC) was added for small scale production. Since then, the Polymers Center has continued to impact economic development through education, research and development, and trial production.
