Welcome to Henan San Kuang Machinery Technology Co., Ltd. – a trusted manufacturer specializing in custom machining for aerospace components. Since our establishment in 2022, we have built a state-of-the-art facility spanning 10,000–30,000 square meters, equipped with advanced CNC equipment and a skilled team of 51–100 employees. Our annual export value of US$2.5–5 million reflects our commitment to serving global markets, including North America, Europe, and Asia. We are proud to offer precision machining of Inconel 718 high-temperature alloy, a material renowned for its exceptional strength and oxidation resistance at extreme temperatures. Whether you need prototype development or large-scale production, our custom machining services deliver components that meet the rigorous demands of aerospace applications.
Inconel 718 is a nickel-chromium superalloy that maintains mechanical properties up to 700°C (1290°F). It is widely used in jet engines, gas turbines, rocket motors, and other high-stress environments. Our machining process is optimized for this difficult-to-machine alloy, utilizing advanced cutting tools, rigid setups, and specialized coolant strategies to ensure precision and surface integrity. Below are the key features and specifications:
Key Features & Benefits
- High-Temperature Performance: Inconel 718 retains strength and resists creep up to 700°C, ideal for turbine blades and combustion chambers.
- Corrosion & Oxidation Resistance: Excellent resistance to corrosion from exhaust gases and high-temperature oxidation, prolonging component life.
- Precision Tolerances: We achieve tolerances as tight as ±0.005 mm, ensuring interchangeability and optimal fit in assemblies.
- Complex Geometries: Our 5-axis CNC machines and EDM capabilities allow us to produce intricate shapes, internal cooling channels, and thin walls.
- Customizable Surface Finish: From Ra 0.4 μm for sealing surfaces to Ra 1.6 μm for general areas, we tailor finishes to your application.
- Scalable Production: From single prototypes to high-volume runs (up to thousands of parts), we maintain consistent quality.

Frequently Asked Questions
-
What is the typical lead time for custom Inconel 718 aerospace parts?
Lead time depends on complexity and quantity. For simple prototypes, 2–3 weeks; for complex production runs, 4–8 weeks. Rush orders are available upon request. -
Do you provide material certification for Inconel 718?
Yes, we source from certified mills and provide material test reports (MTR) with traceability to heat number. -
Can you machine Inconel 718 to very tight tolerances like ±0.002 mm?
We can achieve ±0.002 mm on select features with specialized processes. Please discuss your tolerance requirements during the design stage. -
What surface finishes do you offer for aerospace components?
We offer Ra 0.4 μm for sealing surfaces, Ra 0.8 μm for general bearing areas, and Ra 1.6 μm for non-critical surfaces. Shot peening, anodizing, and passivation are also available. -
Do you have experience with parts for jet engines and turbines?
Yes, we have produced turbine blades, nozzle rings, combustion chamber liners, and other high-temperature components for aerospace clients. -
What is your minimum order quantity (MOQ)?
We accept orders as low as 1 piece for prototypes. For mass production, MOQ is typically 50–100 pieces, but we can be flexible. -
Which quality certifications do you hold?
We are certified under ISO9001, QS9000, and other internal quality systems. Specific aerospace certifications (e.g., AS9100) are in progress – please inquire for details. -
How do you ensure the quality of machined Inconel 718 parts?
We use CMM inspection, surface roughness measurement, optical measurement, and in-process gauging. A full inspection report is provided with each shipment.
