+Plastic Part Design Symposium :.
for Product Designers

Course Duration: 16 hour workshop

Tuition: $1000.00 US

Overview: The course material is designed to provide a working knowledge of the plastics industry. The bulk of your time in this workshop will be spent on the part design requirements imposed on the designer by the injection molding process and by injection molds.

Prerequisites: General knowledge of Pro/ENGINEER Solidworks or another 3dimensional CAD modeler helpful but not nessessary.

To sign up for this workshop we need only two designers to make a workshop.   312.226.8339

Topics:
The process, injection molds, vacuum formed, tooling, processing factors, Nominal Walls, Radii and draft angles, Ribs, Weldlines, stress, cooling plastics, bosses, undercuts,
Also snap fit, FEA, Design recommendations, flow mold analysis software.
Learn to Design injection molded undercuts
Learn about various plastics and their material characteristics
Engineers will learn to utilize tooling and injection molders as a resource to design better parts.
Learn about the metal mold itself and many of its intricacies such as sleeve ejection, how it is cooled, sprue and runner, ejector bars, ejector plats, and ejector pins.

Discussions:
Discuss the history of plastics
Discuss how an injection mold functions in detail. Include mold fill short shots and cooling.
Discuss how China plays a major role in injection molding. Discuss the quotation process for tooling and discuss partnering with local injection molders vs. outsourcing. Discuss strengths and weakness of outsourcing.
Discuss basic design elements in plastic part design. Holes, ribs, thin wall features, bosses, nominal wall, and fill.
Discuss general rules for hollow boss design and discuss best practices. Learn about thin steel or thin blade areas and discuss ways to avoid.
Discuss gating and discuss problems such as fill vent and eject issues as related to. Also discuss how to design in solutions to would be cosmetic problems.
Discuss glass filled and co-injection process and discuss problems associated
Discuss sink marks and discuss how to avoid using relations in parametric software
Discuss cooling time as related to thick sections of plastic. Discuss internal voids and fundamentals of other problems that occur from improper piece part design.
Discuss using parametric modelers in general and discuss examples where using variables with a parametric modeler can save problems in the future with examples in your favorite parametric modeler.
Discuss FEA and stress associated with plastic piece part design with respect to FEA. Keeping in mind the deliverable for FEA is simply to make design recommendations discuss the possible solutions to many of the common molding problems. Keep in mind shrink, stress from sharp corners as related to cavity filling.
List plastic vendors and discuss their role and how designers can leverage their experience.
Discuss the Society of Plastics engineers and their significance in the industry
Discuss tooling and different materials for mold design. Discuss from a machining point of view and compare to cutting graphite for electrode burning of steel.
Discuss how to improve flow of the plastic through the mold and discuss Flow Molding analysis software
Discuss designing undercuts and discuss advantages and disadvantages as relative to costs
Discuss general disclaimers on drawings such as "brake all sharp corners".
Discuss different types of undercuts and side pull options (can be customized if prearranged with CAD manager of your various company)
Discuss what challenges (flow, cooling, ejection, handling, maintenance) a mold designer faces when designing a mold and briefly describe in detail using your favorite parametric software an example for creating the cavity and splitting apart the mold base
Discuss draft as related to Rawal surface texture kits. Discuss how to call out textures on your favorite drawing program with examples.
List 10 different plastics discuss their material characteristics
Discuss plastics and how to apply them to real world applications.
