MATERIALS: PennEngineering’s PEM® large-sized self-clinching studs come in lengths up to 6 inch/152 mm and thread sizes up to ½ inch/M14 to offer a value-added capability that allows users to select from a wide range of variations to tailor fastener to application needs. Among available variations, studs can be ordered in assorted head and clinch styles, including six-lobe, multi-lug, knurl and hexagonal; they can be specially heat-treated to achieve greater tensile strength (up to Grade 10.9); dog point threads will enable quick location of the mating fastener; MAThread®/MATpoint® anti cross-threading design will allow for threads to self-align to prevent jamming, correct off-angle installations and speed production; and all types can be supplied in a range of finishes and coatings. The studs install easily (without welding) using any parallel acting press or automated equipment and embed securely and permanently in metal sheets or sections as thin as .036 inch/.91 mm with hardness up to HRB 85/HB 165. They can reliably attach components or assemblies in the agricultural, automotive and railroad, construction, electrical, HVAC, and material handling industries, among others.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
