Train Parts Manufacturer-Investment Casting Saves Finishing Time


If you’re fabricating parts out of bar metal, chances are that it’s costing you a lot of extra time and money. If those parts require extensive machining, you could be losing significant money in scrap, especially if you’re using pricey metals or alloys.

An increasing number of shops that make metal parts that are intricate, require extensive machining or are produced repetitively or in limited quantities, are finding that investment casting is the ideal solution.

Investment casting offers a variety of alloys while saving finishing time and material waste. The process can also enable a company to combine two or more parts into a single piece, saving on fabrication, welding or assembly and machining time. The range of metals and alloys that can be investment-cast is broad, including low-cost alloys such as carbon and many tool steels or costly alloys such as aluminum, stainless steel, hastalloy, cobalt and inconel.

When it comes to making metal parts, investment casting can provide a high return on investment for your shop and customers. Somewhat overlooked today, investment casting offers opportunities to create “near-net shape” parts of virtually any metal, even in low quantities.

Investment casting is an ideal process for those who fabricate or use metal parts repetitively, whether intricate shapes or components that require precise tolerances. If those parts weigh between 1 ounce and 30 pounds, they can be investment-cast in close tolerances with surfaces that require little finishing.

As opposed to forming parts from bar metal, investment casting is also beneficial for fabricators who want to combine components into a single piece or use pricey metals and want to avoid wasted material while minimizing machine time.

Train Parts Manufacturer look at the somewhat higher initial cost and don’t realize all the savings of investment casting in time and materials. While reducing the demand on machine time is a significant savings, there is also substantial added savings in costly metals used to fabricate many parts. Depending on the metals and alloys used to make the castings, the differences in material costs could be stunning.
