Permanent mold casting is a non-expandable casting technique where the mold is not reformed after each casting is made. In this method, instead of using sand as the mold material, a metal is used as a mold. Typically, cast iron or Meehanite (a dense cast iron) is used as the mold material and the cores are made from metal or sand. Cavity surfaces are coated with a thin layer of heat resistant material such as clay or sodium silicate.
Millennials grew up in a unique era of transition as the Internet began to flourish and social networking took root. The first generation with nearly unlimited resources for knowledge, millennials learn, think, and feel differently about education. Millennials are visual learners who do not learn the same way baby boomers did. Digital content is king. This shift gives educators the opportunity to innovate with new technologies to increase student engagement and encourage a more participatory culture. This holds especially true for STEM education.
You’ve probably used a ballpoint pen to write, a hard drive to store data, a skateboard to zoom around, and, of course, an electric motor to power a household machine or two. But do you wonder what makes them run so smoothly and quietly? Bearings make machines like these run. Without bearings, devices like these would wear out from the effects of friction, and would need to be replaced constantly.
Plant engineering is the function which provides strategic manufacturing knowledge to help a plant engineer manage a plant efficiently, effectively, and safely everyday. The plant engineer is generally responsible for planning, designing, installing, modifying, and maintaining the plant facilities, systems, and equipment. For doing all this, a plant engineer needs a lot of skills: some are technical and some come only from experience working in a plant.
