Metal Mold Casting At least three families of molding and casting processes can be categorized as metal mold processes. These include diecasting (high-pressure diecasting), low-pressure permanent mold casting and permanent mold casting. Unlike sand casting processes, in which a mold is destroyed after pouring to remove the casting, permanent mold casting uses the mold repeatedly. Diecasting Diecasting is used to…
From “transparency” and bubble-wrap-type material to a net-like sponge, we could very well be witnessing the Second Age of Aluminum. Aluminum in its modern form has been around for more than a century. In the 1880s, it was considered more valuable than gold, particularly because it was difficult to produce in a pure form. Ever since what is considered the First…
Nickel alloys are used extensively in industry due to their resistance to corrosion and ability to withstand high temperatures and pressures. Nickel alloys resist high pressures and temperatures, making them well-suited for high-performance applications such as jet-engine blades. They also resist corrosion. That’s why Monel is used in deep-seal mining, where seawater poses a constant threat of corrosion. Nickel is…
The development and practical application of electroplated zinc-nickel alloy coatings began during the 1980s, and its acceptance and use have grown slowly but consistently ever since. So Zn-Ni coatings are not as widely used as other traditional protective coatings. This is unfortunate and likely due to the fact the process and the benefits it brings are subject to some misconceptions.…
Higher safety and environmental regulations in the automotive industry push designers to use stronger, lower-density metals. Engineers wrangling with material technology continuously try to find the right balance of properties. However, it’s safe to say that two properties have remained constant over the years—stronger and lighter. Around the end of the last millennium, tighter regulations caused the automotive industry to…
