Heat Shields & Fairings
Hi-Tek Manufacturing manufactures heat shields and fairings for use in the gas turbine application. Composed of a high temperature super alloy, the components varied in size from 6" to 16" in length, 4" to 8" in width, and 4" to 8" in height. The finished part featured a material finish of 16 RMS and was run though X-ray, FPI, CMM, and hard gauging to insure that we met the customer's specifications.
AS 9100D Certification Including ISO 9001:2015
Hi-Tek Manufacturing uses various tools and methods to provide an ongoing effort to improve its products and processes. One such method used to provide Continuous Improvement is centered on the DMAIC process.
Process Capability Measurement
As the Hi-Tek quality team populates customer requirements, process capability is the assurance of the repeatability of each manufacturing operation.
The use of laser ablation technology allows us to precisely clear the thermal coating, a much more precise process than _____ preventing us from having to ship the part to another facility mid-process
Turbine Root Form Grinding
Turbine root form grinding improves the surface integrity of the jet engine turbine blades by applying less residual stress. A reduction in stress results in extended fatigue life, allowing ground turbine parts to run faster and for longer periods than milled or broached products.
Hi-Tek has a met lab staffed with engineers that has decades of experience. Tests that are typically performed in the lab include failure testing, corrosion testing, chemical analysis, weld testing, and metallography
The sinker EDM process is largely used to create complex cavity shapes in tool and die applications. Such applications include metal stamping dies and plastic injection molds
Tungsten Inert Gas (TIG) Welding
Many aerospace components produced by Hi-Tek require TIG welding. Multiple TIG welding stations are maintained and staffed by fully trained and certified welders using industrial certified equipment. In addition to Nadcap certification, Hi-Tek's TIG welding and weld repair if fully certified/approved by all of its aerospace prime customers.
Fluorescent Penetrant Inspection (FPI)
Hi-Tek maintains two full time Level III FPI inspectors that operate state-of-the-art equipment to ensure quality and compliance to specifications, drawings, and models
Fast Hole EDM
Electrical discharge machining, or EDM, is a reductive process that eliminates the need for a traditional tool head and all of the problems that come with it.
Vertical Cylindrical Grinding
HI-Tek has Cylindrical Grinding capabilities for parts as tall as 42", outside diameters up to 42". The X-Axis and Y-Axis have 36"x 36" travel with linear glass scales in all axes. The T-slot table is 36" in diameter, and the fully enclosed machine uses a single point dresser on the OD/ID grinding spindle.
Creep Feed Grinding
Our 10-continuous dress creep feed grinding machines utilized open structured wheels and robust coolant delivery systems to accurately and effectively remove super alloy material across complicated geometries found on fir tree / dovetail shapes as well as other surfaces.
Hi-Tek has many 3 & 4 Axis Vertical Milling machines and 5-Axis Vertical & Horizontal Milling machines
