Casting our Foundry for your Molding Needs

March 4, 2013

Which type of casting is most appropriate for your medical, automotive, or component application? What is the difference between plaster mold castings and sand castings? When is a prototype casting the best option for your desired use? If you are in the market for extensive foundry work and expertise, then we would like to welcome you to our Pattern Shop and foundry.

How do we decide on which casting process to use? Depending on the geometry and configuration needed for the component, our foundry experts choose the most appropriate process to achieve the component’s desired applications.

In our foundry, we work with both plaster mold castings and sand castings, again giving K&H the unique opportunity to combine the two in a hybrid casting process. This allows us to quickly turnaround prototype castings from volumes of one to one thousand, in a variety of casting methods. Here’s a brief outline on each type of casting we offer:

Plaster mold castings: This type of casting will closely resemble a die casting, typically featuring thin wall thickness and tighter tolerances. Additionally, plaster molds have more of a Plaster Moldsmooth and cosmetic surface finish.

Sand mold castings: Made with fine sand, these castings tend to be heavier castings with substantial wall thicknesses, though we use a fine no-bake sand so that the surface finish is still not that of a plaster molded part. They allow for ornate detail and are the more traditional castings.Sand Mold

Hybrid mold castings: This combination allows thin wall castings in combination with heavy sections, so it is still maintaining good structural integrity, cosmetic surfaces where required, and low porosity.

K&H offers a unique system to keep your costs to a minimum; many of our customers take advantage of our KAN-BAN inventory system. With this we will cast your yearly order, machine and finish the components, and store them at our facility. You only order the quantity needed for the month or week, thereby reducing your cost through quantity, have a week or less lead time, and no in-house inventory.
