Investment Casting vs Die Casting? Which One Should You Choose?

Casting is a tried and testing method of manufacturing. There are various techniques, but most involve pouring a liquid material into a mold. When it hardens, the mold is removed and various treatment procedures can be applied for a stunning finish. The process is mostly used to create solid and hollow designs in a wide range of industries.

Though conventional methods still apply, technological advancements have led to the evolution of casting. There are specialized varieties for different applications, including die casting and investment casting. If you’re interested in the latter, PPCP Inc in Lebanon is an example of a company that produces investment castings. If you’re wondering whether you should work with a specialist like this, you’re in the right place.

This article has collected advantages and disadvantages of different casting methods. This will help you make an informed decision.

How Does Investment Casting Work?
The process involves creating a wax pattern, which is repeatedly dipped into a liquid ceramic slurry. When the material hardens, it takes the shape of the casting. When the wax has melted out, molten metal is poured into a cavity. The metal solidifies in the mold and can be extracted accordingly.

How Does Die Casting Work?

This involves forcing molten metal under high pressure into a die cavity. These are created with hardened tool steel that has been machined in the shape of die cast parts. This can be used to manufacture parts for various functions, including those in the automotive industry. Replacement parts can be produced for truck repair shops, underlining the usefulness of the process. If you work in this industry and need repairs, use a directory for truck repair shops such as FleetPal to help you find something suitable. Here you can find maintenance solutions across the United States.

Which Process is Right for Me?

To help you discover the best method for you, we’ve prepared a few key considerations when evaluating the casting process. There isn’t a one-size-fits-all solution, since every project, product, and company is different. By reviewing the points below, you can make a better decision on which casting method is applicable.

Design Complexity

The complexity of your design geometry is a huge factor. Investment casting is great because it offers great design flexibility. You can cast intricate shapes, incorporating interesting design features like logos and other information.

You can achieve precise results for complex geometries. Die casting offers dimensional results, but nothing like Investment casting.

Material Selection & Annual Usage

Investment casting is suitable for various alloys. There are greater material options than with die casting, providing useful flexibility. Alloys can be cast that would be challenging with a machine. Investment casting is good for smaller production runs, but with the right budget can be used in larger production. Die casting is ideal for high-volume products, because it relies on excellent consistency and repeatability.

Part Size & Tolerance
Investment casting can accommodate casts up to 200 pounds. There is some limitation to the size of parts you can produce, like with die casting. Here there are similar size limitations, which are less restrictive than with Investment casting. Investment Casting delivers on tight tolerances, where the smaller the casting, the greater the dimensional accuracy. On the whole, die casting is more suitable for large-scale pieces, but that doesn’t mean investment casting loses relevance in these situations.
