An Introduction to Impro Mexico’s Investment Casting Process Capabilities

June 22nd, 2023

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

Inconel® Investment Casting

June 6th, 2023

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.

An Introduction to Making Gas Turbine Nozzle Assemblies

June 1st, 2023

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

Quality Control in Investment Casting

May 19th, 2023

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.

Introduction to Impro’s Total Manufacturing Solutions for Gas Turbine Nozzle Assemblies

May 11th, 2023

The end covers, fuel nozzles, ,bearing housings and associated components at the heart of a gas turbine are some of the hardest parts of any kind to manufacture. Forged and cast from high strength alloys, it takes precision machining of

Precision Aluminum Investment Casting

April 26th, 2023

A high strength-to-weight ratio, excellent thermal conductivity and good corrosion-resistance are just some of the reasons for using aluminum. If you’re looking for low mass, good heat transfer, or the opportunity to avoid coating processes, precision aluminum investment casting is

Creating Molds for Investment Casting

April 18th, 2023

The investment casting process produces parts with fine features, thin walls and excellent surface finish. This cuts down on machining operations, and reduces the amount of metal needed, lowering part mass and saving time and cost. However, these advantages are

Draft Angles in Investment Casting

March 14th, 2023

Draft angles on cast parts limit the designer’s freedom and complicate secondary machining operations. One of the advantages of investment casting over other casting processes is that draft angles can be practically zero. This blog post explains what draft angles
