From Design to Reality: The Journey of a Cast Metal Part
June 3rd, 2024
Manufacturing should always be considered during product design. Preferably, it should be discussed with the team or supplier who will make the part. Skipping or rushing this part of the development process leads to parts that cost more than they
Advances in Gas Turbine Nozzle Assembly Technology
May 21st, 2024
Higher temperatures and pressures increase gas turbine efficiency and reduce emissions, but at a cost. Components downstream of the combustors suffer more fatigue and wear, resulting in shorter lifetimes and more repair work. Gas turbine component manufacturers are responding with
The Role of 3D Printing in Investment Casting
March 5th, 2024
Investment casting yields accurate metal parts with detailed features, thin walls and smooth surfaces. This is achieved by using wax patterns that replicate the part being made. These patterns can now be made by 3D printing, which saves time and
Materials Matter: Choosing the Right Alloy for Investment Casting
January 30th, 2024
Investment casting works well for complex parts with fine features. Being near-net shape, it minimizes secondary machining, which can lower costs and reduce lead time. It’s not ideal for all metal alloys though. This blog discusses what’s involved in choosing
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
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
