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.

Comments Provided by Students

• Great course, very instructional…love the PowerPoint notes

• The instructor uses examples that are relevant to my industry/field

• The overall explanation of the basics of Plastics was very clear and concise, explained in plain English

 without having to use big and sophisticated words to explain theory or function

• The course’s major strength was instructor’s ability to relate to real life experience

• Very Practical – I highly recommend to anyone new to plastics industry

• Hand-outs are great, I refer to them on regular basis


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.

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.


Course Content

• 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.

• Prototyping


Time/Dates: Saturdays, 9:00 AM-2:00 PM, October 07 – November 18, 2017 (7 mtgs)
