Core Box Design And Production
LeClaire Manufacturing is an expert manufacturer of robust sand and permanent mold casting cores. As a matter of fact, we make some of the most complex core boxes and assemblies for aluminum castings in the country. Our largest core assembly, consisting of 21 cores and 4 chills, helped make a leak-tight braking component.
Our experienced, highly skilled design team assists in developing core concepts, helping offer you maximum flexibility. Whether the design calls for a top- or side-blow core machine or hot box or Isocure™ cold box processes, our equipment is up to the task!
The Core Making Process
Core making is an essential part of creating cast products, since cores enable more complexity in casting by allowing for hollow areas and a greater range of structural elements. We create the cores through either a hot box or cold box method, both of which operate on similar principles:
- Sand gets blown into a core box, the tool used to form the core
- This sand mixes with a resin to act as a bonding agent
- The resin cures, either through a catalyst (in the cold box process) or through baking (in the hot box process)
- The core is inserted into the casting tool where molten material forms around it before being removed so that the sand and resin are no longer present in the finished piece.
Multiple cores can be combined and used in this way to create highly complex pieces, as in the leak-tight braking component example described above. Our foundry core making machines and equipment can create simple components as well as those meant for more complex applications. We also can assist you with design choices and process questions, ensuring our equipment operates up to your standards in creating a high-quality product.
Why Is the Core Making Process in Castings Important?
A high-quality core can impact your product in several ways, including:
- The quality of the finished piece
- Production efficiency by limiting the number of malformed parts
- Holding down overall production costs
Low-quality cores may fail during the pouring or setting step of the casting process, resulting in an inaccurate or incorrect part. In these cases, a new one must be created, and the process restarted. This extends the production process and introduces additional costs. At LeClaire Manufacturing, we pride ourselves on high-quality cores for the agriculture, military, heavy vehicle, marine, and valve and pump industries, among many others.
