Southern California Section of the Society of Plastics Engineers
Promoting the scientific and engineering knowledge pertaining to plastics.
The College of the Extended University Cal Poly, Pomona
Plastics Engineering Technology Certificate Program
Saturdays, September 16th and 23rd, 2017 - Time: 8:00 AM to 5:00 PM
Scientific Injection Molding
The course emphasis is on scientific approach to a somewhat complex injection molding process in
order to simplify and eliminate basic misunderstanding about processing techniques employed today
throughout the industry. Students will learn the importance of understanding polymer basics, material
flow properties, viscosity-shear rate curve, and major plastics variables in molding, decoupled molding
techniques, data analysis and interpretation.
The course will cover fundamental and scientific approaches to material drying, venting, cooling, use of
regrind, how to prepare universal set-up sheet, cycle time optimization, tooling considerations, etc. Use of
modern tools and techniques such as mold flow analysis, cavity pressure transducers, and data acquisition
tools along with troubleshooting techniques will also be covered.

About the certificate program:
Plastics engineering encompasses the processing, design, development, and manufacture of plastics products. Cal Poly Pomona offers one of very few programs in Southern California devoted to the plastics engineering industry. This program will provide you with an in-depth look at plastics engineering technology from a technical and non-technical view.
This three-course certificate program provides practical instruction in materials, processing, product design and tooling. The practical knowledge gained on the aspects of Plastics Engineering technology can be applied to all sectors of the industry including manufacturing, design, sales, and customer service.
PLASTIC ENGINEERING – PART DESIGN FOR INJECTION MOLDING
(Course Code MAE-40033) Section ID 127494
Expanding Skills in Plastic Part Design for Injection Molding
Plastics have increased their penetration of engineering applications that push the limits of part design,
molding techniques and processing ranges. Plastic parts, often complex and large, are calling for better
quality control and dimensional tolerances. Resin families and compositional variations have proliferated.
Growth in the plastics industry has led to a constant influx of new people from other technologies who
need to begin developing skills in the field of engineering plastics. People working in the industry need a
good working knowledge of plastic part design.
Who Should Attend?
The course is primarily for designers, engineers, and technicians directly involved with making parts out
of plastics. However, those in related activities ranging from management, purchasing, and quality control
can benefit from the course by developing a better appreciation and understanding of the process of
designing a plastic product.
• Process of product design
• Fundamentals of plastics. Strength of materials, non linear considerations
• Materials selection in product design
• Molding and tooling considerations in part design
• General principles of part design. Short term loads, long term stress exposure
• Creep and relaxation in part design. Understanding safety factors in design.
• Dimensional analysis in part design
• Assembly techniques: design of snap-fit, press-fit, fasteners, ultrasonic, vibration welding, heat
staking, adhesive bonding.
