SUMMARY:Injection Molding Principles
DESCRIPTION:Course Description\nInstructor: Brad Johnson \nFee: $1\,600 \nEducational Goals\nThe Injection Molding Principles workshop is designed to provide a thorough understanding of injection molding basics and terminology. Hands-on experience through lab exercises reinforces the concepts introduced in the classroom sessions. While in the lab\, a maximum of four participants per press will allow each participant the opportunity to learn by doing. Participants are encouraged to bring their problem parts to the workshop for diagnosis and discussion during the problem-solving session. \nWho Should Attend\nThose who want to improve their knowledge of thermoplastic injection molding technology and the language needed to succeed in the business of plastics should plan to participate. Among those who can benefit from this two-and-one-half-day workshop are operators\, process and project engineers\, manufacturing engineers\, molding technicians\, team leaders\, designers\, mold makers\, and sales and marketing staff. \nCourse Outline\n\nOverview of the Injection Molding Cycle\n\nThe injection unit\nThe clamp\nThe mold\n\n\nInjection Control\n\nThe feedback loop\nCharting pressure and velocity\nUtilizing velocity-controlled filling\nPressure limited velocity\n\n\nPlastics Flow During Injection Molding\n\nThe worm analogy\nLaminar flow and fountain flow\nEffects of temperature\, pressure\, and molecular weight\n\n\nShrinkage and Volume Changes\n\nPressure-volume-temperature relationship\nAmorphous and semi-crystalline materials\nCavity pressure and mold shrinkage\nFlow and temperature effects\nFiber fillers\n\n\nProblem Solving\n\nQuality planning\nTroubleshooting common molding defects\nDOEs and other tools\n\n\nMolding Strategies\n\nTraditional molding\nTwo-stage molding\nThree-stage molding\nVelocity to pressure transfer methods\nProcess monitoring\nInitial mold tryout procedure
