Casting Processes: When To Use Which Method

Posted by Dave Olsen on 7/17/18 10:10 AM


There is more than one way to bake a cake. Ingredients, temperature, bake time, and how many you are serving dictate your approach. Making brownies for the third grade class is not the same as baking an elaborate wedding cake for 350 degrees.  The same is true when it comes to selecting a right metal casting process to manufacture any component.  Which process offers the best all-in cost, considering requirements for features, material, quality, and quantity?  

The list of methods to produce metal parts is long, and includes machining/hogouts, forging, fabrication, and more. In this article, we will just discuss various casting processes you might select to make an important component.

What to Look For When Choosing a Casting Supplier

Posted by Dave Olsen on 2/5/18 2:05 PM

The process of choosing the right metal casting supplier should not be the same as choosing your supplier for bolts, manufacturing equipment, or office supplies. While some may treat metal castings as a commodity, they are far from it and the process for selecting the right supplier for a specific application requires careful consideration.

Supplier qualification is the most important part in the purchasing process. Traditionally, a purchaser’s primary responsibility was to find qualified and responsive suppliers. In some cases, purchasers assumed that any supplier willing to contractually meet the purchase requirement was qualified. However, using low cost and unqualified suppliers can cause quality issues, and wasted time and money in the long run.

To help you through the process, here are some things to consider when choosing the right metal casting supplier.

What Is The Continuous Casting Process?

Posted by Dave Olsen on 4/18/17 2:40 PM

Overview of Continuous Casting

Continuous cast shapes are produced by introducing molten metal into a vertical or horizontal mold that has the ability for rapidly chilling the metal to the point of solidification. The rapid chilling in the mold ensures a fine, uniform grain structure in the solidified metal with higher physical properties than sand castings. Once solidified, the cast shaped bar is cut to a desired length.

The most common shapes produced are tubes and solids, but square, rectangular, hexagonal, and many other irregular shapes can also be produced to match a desired finished part profile.
