Advantages of Sand Casting for Exhaust Manifolds

November 7th, 2023

The list of processes for making exhaust manifolds includes several casting technologies. Selecting the optimal one entails considering quantities required, the physical size of the manifold, geometric requirements, details of the application, service life, and of course cost. In most

Applications of Gas Turbine Nozzle Assemblies in Power Generation and Aerospace

October 30th, 2023

Gas turbines are deployed on the ground and in the air. The two use cases are very different, yet the fundamentals remain the same: a continuous combustion process generates thrust and rotary motion. Impro is a leader in parts for

Applications of Swiss Screw Machining in Various Industries

October 24th, 2023

Switzerland is famous for high quality watches, and tiny, high-precision screws contribute to their success. Today, though, the machine tool technology developed to make these intricate parts is used to produce a host of other items too. This blog explores

Maintenance and Repair of Gas Turbine Nozzle Assemblies

October 17th, 2023

Nozzle assembly components don’t last long in the challenging environment inside a gas turbine engine. Thermal cycling causes fatigue, high temperatures cause creep, and corrosive gasses erode precisely machined surfaces. If not monitored closely and inspected regularly parts can fail

Introduction to Impro Mexico’s Precision Machining Process Capabilities

October 10th, 2023

Our precision machining facility produces complex, high value-added, mission-critical components from bar stock for customers in transportation, agricultural and construction equipment, industrial machinery and other industries. These precision machining operations launched in Mexico in 2016. In 2021 they were transferred

Common Problems with Hydraulic Orbital Motors and How to Fix Them

September 27th, 2023

Agricultural, construction and landscaping machinery use hydraulic orbital motors because they’re rugged and durable. When sized correctly for the application and maintained correctly, they will provide years of trouble-free service. However, on rare occasions, issues can arise. This blog identifies

Material Selection for Gas Turbine Nozzle Assemblies

September 19th, 2023

Not many alloys can survive in the environment downstream of the combustion chamber in a gas turbine engine. It’s too hot, forces are high, the gases are extremely corrosive and they’re flowing quickly. Together, these factors make material selection one

Manufacturing Techniques for Gas Turbine Nozzle Assemblies

September 12th, 2023

In a gas turbine engine the nozzle assembly comes just after the combustion chamber. It directs fast moving gasses onto the turbine blades that generate the rotary motion needed for power generation. It’s a complex piece of engineering, produced in

Vacuum Brazing and its Applications

September 5th, 2023

Like welding, brazing is a method of permanently joining separate metal pieces. Where brazing differs though is that there’s no melting of the pieces being joined. This makes it the preferred process in applications where it’s important that material properties

17-4 Stainless Steel Investment Casting and its Applications

September 5th, 2023

Stainless steel is produced in a large number of grades that have austenitic, ferritic or martensitic structures. 17-4 is a martensitic grade that can be precipitation hardened, (leading to the 17-4 PH designation). It’s often investment cast and is a

Thin-Walled Investment Casting and its Applications

August 29th, 2023

Wall thickness refers to the distance between opposite sides or surfaces of a solid metal cast region. In a part like a cover the wall thickness is the distance between inner and outer surfaces. Thin walls are difficult to cast,

Manufacturing Combustion Parts for Aircraft Engine and APU Applications

August 21st, 2023

The heart of the axial flow turbine engine is the combustion chamber. This is where fuel and air are mixed and ignited, with air velocity determining how far through the chamber the flame front extends. Parts used in the combustion
