The injection mold is an extremely important element of any plastic injection molding operation. Molds determine the shape of the part, vent trapped air or gases during injection, act as heat exchangers to solidify the molten plastic, and eject the cooled parts. This Plastic Injection Molds program highlights the primary injection mold components, including the mold base, cavity and cores, runner system, cooling system, and ejector system. This program also features segments on injection mold types, the use of computer simulation, mold prototyping techniques, and mold maintenance & repair. The Injection Mold Types segment showcases in detail the cold-runner two-plate mold, the cold-runner three-plate mold, the hot-runner mold, and the insulated runner mold. The Plastic Injection Mold Production segment explores the use of computer simulation to develop molds, mold production methods, mold prototyping techniques, and mold maintenance & repair.
Great for anyone from novices to seasoned lean practitioners, this program shows you how to identify the seven wastes of lean by going through the process with two companies.
Design for manufacture and assembly (DFMA) is a proven design methodology used to optimize part costs and quality, while reducing time-to-market development. Part of the award-winning Manufacturing Insights Video Series, this program features an interview with Nicholas Dewhurst of Boothroyd Dewhurst. He explains the concepts and use of DFMA in product analysis to understand the drivers of cost, and the interaction of the individual pieces within the product to optimize design, manufacturability, and assembly.
This Filament Winding program examines both the wet winding and dry winding processes. The primary types of filament winding methods are detailed including: hoop winding and helical winding. This program also features an in depth look at the types and uses of filament winding mandrels. This program is part of an eight program Composites Manufacturing series.
Quality tooling is a fundamental requirement for the manufacture of composite parts. This is due to the fact that every step in the composite part manufacturing process must be tightly controlled to ensure superior material properties and predictable performance in the final product.This program explores the composite materials used for tooling and tooling design.
Thermal cutting processes use heat for cutting. The abrasive waterjet process uses no heat, but cuts by abrasive erosion. All these processes provide precision non-contact cuts in a wide variety of materials, and cut in single pass, rather than multiple passes. To better understand the various cutting processes, this program examines, explains, and compares oxy-fuel cutting, plasma cutting, laser cutting applications, and abrasive waterjet cutting.
Electrical discharge machining (EDM) shapes metal by creating sparks that melt tiny portions of the workpiece, and is an exceptionally diverse process that generates no cutting forces. EDM is especially useful in the production of fragile parts that cannot take the stress of conventional machining. This program examines the EDM process and the two primary forms of electrical discharge machining — ram EDM and wire EDM.

By using GD&T, a print can explicitly call out necessary tolerances in an unambiguous fashion. Using shop floor footage and animations to illustrate examples, this program introduces the viewer to GD&T rules and concepts. The 14 symbols used in GD&T are highlighted with examples to define their use.
