Course content

1 section • 8 lectures • 2h 19m total length

  • Importance and Classification of Plastics6:49

    Explore why plastics dominate modern products: molding enables final-shaped parts with less energy than metals, and plastics offer hollow and solid molded parts, films, foams, and coatings.

  • Plastics can shape into products as3:44

    Explore how plastics form molded parts, extruded sections, films, sheets, wire coatings, and melt-spun fibers, tracing their manufacture from petrochemicals derived from crude oil to everyday products.

  • Properties of Polymer Melts -Viscosity and Visco-Elasticity19:05

    Explore how polymer melts flow in molding, focusing on viscosity and viscoelasticity, comparing Newtonian and pseudoplastic fluids, and noting temperature and shear-rate effects on viscosity and die swell.

  • Compression Molding – Features, Advantages & Disadvantages9:32

    Compression molding for thermoset plastics uses a heated mold, compresses the charge to shape, and cures it to a part; it offers simple molds and low scrap but slower cycles.

  • Transfer Molding – Pot & Plunger Transfer Molding9:43

    Explore transfer molding, loading the charge into a heated chamber and using heat and pressure to flow resin into the mold, via pot and plunger transfer methods.

  • Blow Molding – Extrusion and Injection Blow Molding28:55

    Learn how blow molding creates hollow, seamless plastic parts from a parison using extrusion and injection processes, including stretch blow molding and wall thickness considerations.

  • Injection Molding38:05

    Learn how injection molding uses heated thermoplastic polymer under high pressure to fill a two-plate mold, producing solid and hollow parts in 10–30 second cycles.

  • Inspection of Plastics Parts Manufactured by Molding Processes23:32

    Assess plastic parts produced by molding by examining shrinkage, cooling, and common surface defects such as short shots, air bubbles, and flushing.

Requirements

  • A strong desire to learn about plastic manufacturing processes and their applications in various industries.
  • A fundamental understanding of chemistry and materials science is recommended but not required.
  • Familiarity with basic math concepts such as algebra and geometry.
