Sensor components are often compact, complex, and require micron-level precision to ensure accurate signal
detection and environmental durability.
At Reko, we specialize in machining miniature housings,
connectors, and mechanical structures for various sensors — guaranteeing consistent accuracy and stability
under harsh conditions.
In the aerospace industry, aluminum is among the most widely used metals. As the third most abundant metal on
Earth, aluminum perfectly meets the high standards required in aerospace applications. Its lightweight, high
strength, and good toughness make it ideal for aircraft structural components, engine parts, and aerospace
electronic devices.
We process components for diverse sensor types including temperature, pressure,
flow, position, acceleration, and optical sensors, covering core structural parts such as housings, brackets,
connectors, and heat sinks. Equipped with advanced five-axis machining centers, 3D coordinate measuring machines,
and an experienced engineering team, we not only meet complex structural and high-precision machining demands but
also shorten delivery cycles while ensuring quality.

Manufacturing sensors is far from simple. From ultra-tight tolerances and delicate geometries to diverse material requirements and demanding surface finishes, every step presents unique challenges. Consistency, reliability, and compliance with strict industry standards make sensor production even more complex. Overcoming these obstacles requires advanced CNC machining capabilities and rigorous quality control.
Machining housings and components with ±0.01mm or better tolerances is critical but difficult to maintain consistently.
Many sensor parts have thin walls, deep cavities, or micro-holes that are prone to deformation during machining.
Engineering plastics and stainless steels used in sensors have very different cutting behaviors, challenging tool selection and stability.
Functional surfaces often require Ra 0.8μm or finer, making surface finish control a challenge in mass or small-batch production.
Anodizing, passivation, and plating must ensure corrosion resistance and airtight sealing, while avoiding defects like uneven coating.
Machining precise sealing grooves and connector threads requires both accuracy and repeatability.
During CNC machining, heat and cutting forces can distort small or delicate sensor parts.
Tiny features and surface-treated parts require advanced inspection methods (CMM, profilometry), increasing complexity.
