Powder metallurgy is a rather young industrial technology. The first local industries were started mid last century. During the next 30-40 years business expanded primarily within the continents and since the last decade the rate of expansion has accelerated and today the business is truly global. This global business requires new modern tools to support further growth and sharpening of the weapons to compete with other manufacturing technologies. In this context ISO standards supports confidence in powder metallurgy and guides end users, often with global presence, to make the right choice to use components and solutions based on metal powder.
These design tips will give you some guidance in designing a component to take advantage of what Powder Metal has to offer. Following these parameters will help to reduce the costs of tooling and increase efficiency of production. This is not intended to be an exhaustive guide. Feel free to call PMCo early in the design process so that we can help maximize your component for Powder Metal production.
On of the major advantages of using Powder Metal for production of components is the wide variety of raw materials that can be used to math your needs with regard to cost, durability, quality control, and special needs applications. Metals commonly used include iron. steel. tin, nickel, copper, aluminum, and titanium. Refractory metals such as tungsten, molybdenum, and tantalum may be used as are bronze, brass, stainless steel, and nickel cobalt alloys.
Let’s take a look at how Powder Metal compares with alternative production methods which you may want to consider. If it is feasible to make your component with one die and one stamping, stamping will usually be a logical and economical choice. If the part is more complicated and requires multiple dies or a progressive die, tooling costs and production costs may make Powder Metal competitive.
