One of the reasons for having parts made by investment casting is that the process is capable of maintaining tight tolerances. This minimizes secondary machining and enables reproduction of fine. What’s left unasked though is, what tolerances can investment casting
Swiss screw CNC lathes are highly productive machines, but running them at less than maximum efficiency can mean a significant loss of output. This blog explains the kind of precision machining work they are best suited to and how to
Exposed to hot, fast moving and corrosive gasses, exhaust manifolds need an uncommon set of qualities if they are to survive and contribute to efficient combustion. Impro successfully sand casts these parts in a specialized metal and by paying close
If you’re looking for a North American source of investment castings, Impro can help. We started investment casting at our plant in Mexico in late 2022, and with extensive precision machining services on site, we’re able to finish as well
Impro uses sand casting to produce engine blocks for high horsepower and other applications. Sand casting has advantages over other casting processes, but also poses some challenges. Here’s an introduction to how iron engine blocks are made. Design Expectations and
The tough alloys used for demanding applications in the oil and gas sector pose serious machining challenges. Cutting forces are high, inserts wear rapidly, and chips refuse to break. Add these problems to the tight tolerances and complex geometries required
Many components of power generation equipment perform best when produced in cast iron. It’s a metal that can dampen vibration, distribute heat, hold up to wear and withstand high loads. Impro sand casts an extensive range of components in iron
It’s said Swiss machining originated with the need to produce tiny screws for the Swiss watch industry. True or not, the definition has broadened over time. Today it describes a technology for precision machining small cylindrical parts quickly and efficiently.
Engineers turn to nickel-based superalloys when stainless steel can’t provide enough corrosion resistance or high temperature strength. The downside of alloys like Inconel® though, is that they are hard to machine. This makes investment casting the most practical manufacturing route.
The combustion gases expelled from a gas turbine will quickly erode and can even melt most steels. For internal components to survive in such an environment, they are investment cast in nickel-based superalloys, precision machined and carefully inspected. Here’s an
Investment casting is ideal for producing parts that will be highly loaded, subjected to high temperatures and pressures, or require precise geometry that minimizes secondary operations. This is especially true when the alloys used are expensive and hard to machine.
Cavities in parts made by sand casting, like valve bodies, pump housings, and engine blocks, are there mainly to channel, guide and hold fluids. They can also reduce finished part weight and save on material. In principle they could be
