Why heat treat?

Iron, in its pure form, is lustrous, silvery, and soft. Iron’s electrons can spin in the same direction, which means it effortlessly combines with alloying elements. Iron is also polymorphic. Its crystal structure can transform into different forms by changing the temperature and carbon content. Iron’s properties make it valuable to metallurgists and engineers. The team at Penn-Mar Castings knows just what your iron component needs in terms of alloys and temperatures to perform its intended function in...

PMC casting pattern blog

Optimizing the pattern of a casting

Designing a pattern can be challenging, especially if you don’t have a well-defined process. At PMC, the design review process begins when the customer and the foundry’s casting engineer review the required casting shape. It consists of drawings or models of a casting-friendly pattern and more core boxes. Technical discussions typically include tolerances required, allowable machine stock, machined and non-machined surfaces, and the castablility of the desired casting. Tooling design can vary, depending upon the pattern material, casting...

Industries that rely on castings

Metal casters can develop complex shapes in many sizes using a wide variety of materials with unique properties that serve many different purposes. That’s why metal castings are vital to many key industries such as agriculture, healthcare, and mining. Without castings, these industries and the role they play in our everyday lives wouldn’t be the same. Agriculture “Agriculture is the world’s oldest industry; without it, society as we know it would not exist (avalon-castings.com, n.d.). Farmers grow the...

PMC reduce cost blog

Reduce the cost of your casting

A lack of casting knowledge is at the root of nearly every cost driver for castings. To complicate matters, even if you have general knowledge or experience in casting, every foundry uses different processes. What works to reduce cost in one operation can drive up the cost in another. Even if you have general casting knowledge, get the foundry involved as early as possible in the design process. Casting engineers and designers have greater control over the cost of...
