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

An Introduction to Sand Cast Iron Engine Blocks

June 20th, 2023

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

Precision Machining for Oil & Gas Applications

June 15th, 2023

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

Sand Casting for Power Generation Equipment Applications

June 13th, 2023

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

Overcoming Common Challenges in Swiss Screw Machining

June 8th, 2023

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.

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.

Creating Internal Cavities in Sand Cast Parts

May 19th, 2023

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

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

Sand Casting for Commercial Vehicle Applications

May 9th, 2023

Components used in commercial vehicles must have strength, toughness, and a little ductility. Good heat transfer properties and low density are bonus factors. These requirements push part designers to the family of cast iron alloys, and this is a metallurgy

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
