Seminar Scope

This seminar will focus on complex phenomena behind the Injection Molding process, with strong emphasis on the understanding of part's problems (aspect, shrinkage, warpage, weld lines, burns, ...) and their relationship to material properties (amorphous, semi-crystalline, filled, unfilled) and the process itself.

The participants we expect could be :

	design engineers in charge of molded parts
	mold making specialists
	molders
	flow analysts looking for analysis interpretation support
	project leaders involved in developing molded parts
	research engineers interested in injection molding
	mechanical engineers interested in process induced weakness and strength
	material engineers or designers whishing to improve their understanding of a given class of materials (i.e. glass fiber filled polymers).
	students involved in the field
	young, skilled professionals with little field experience
	flow analysis developers
	customer support engineers
	....

The first part of the seminar will quickly describe the process cycle for the purpose of setting up a common vocabulary.

The seminar may not fit the needs of beginners in the field.

Detailed Content : The questions we will answer

The subject of the present course is not Flow Analysis. However the intention is clearly to help attendants gain a thorough understanding of the concepts that form the basis of existing code. Model assumptions and corresponding limitations will be highlighted and discussed.

The seminar will be highly interactive, with limited attendance, allowing for questions, group discussion and analysis of the attendant problems.

The last afternoon is entirely dedicated to working groups and the Moldflow software will be used to interpret participant exercices.
