Product Introduction

We focus on the high-precision manufacturing of Aero Engine Blade, covering key aerodynamic components including fan blades, compressor blades and turbine blades.

Our products adopt a combined process of precision electrochemical machining (PECM) and five-axis simultaneous ultra-precision cutting technology, which enables efficient machining of difficult-to-machine materials such as nickel-based superalloys and titanium alloys, and achieves excellent surface integrity and aerodynamic precision.

Our blades are widely applied in aero engines, gas turbines and aerodynamic prototypes for experimental verification, providing customers with customized solutions that meet the requirements for high temperature, high stress and high reliability.

Frequently Asked Questions

What information is required to quote a custom Aero Engine Blade?

Please provide drawings, 3D models, material requirements, surface treatment requirements, quantity, accuracy requirements, and application scenario. If physical samples are available, they can also be supplied for structure and process evaluation.

Can samples be made first for validation?

Yes. We support sample development and small-batch trial production. Customers can complete dimensional confirmation, assembly testing, and fit validation before moving into subsequent batch production.

What is the typical sample development lead time?

The sample development lead time is typically 7-45 working days. The exact schedule will be confirmed based on the structural complexity of the aero engine blade, material, machining process, heat treatment, and surface treatment requirements.

What is the Minimum Order Quantity (MOQ)?

The standard MOQ is 10 pcs. It can also be discussed flexibly based on sample testing, small-batch trial production, or the planned follow-up batch order.

Do you support the process from small-batch trial production to batch production?

Yes. We can support sample development, small-batch validation, and batch production according to the customer project schedule, while maintaining consistent machining standards and dimensional consistency for repeat orders.
