Choosing the Right Material for Swiss Screw Machining
December 5th, 2023
Swiss screw machining is valued for its ability to produce complex parts while driving down individual piece costs. This blog explores how material selection contributes to that goal, while helping meet design objectives. Parts Produced by Swiss Screw Machining Swiss-style
Introduction to Air Flow Test in Precision Parts Manufacturing
November 14th, 2023
Mass air flow measurement provides a functional test of precision machined parts like those used in gas turbine engines. It’s important for minimizing temperature variations and vibration, preventing overheating and maximizing efficiency. Impro Aerotek produces and repairs the highly engineered
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 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

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
