Product Description
304 316L Stainless Steel Precision CNC Milling Metal Small And Micro Parts
Product Application
These are ultra-precision, small-scale metal parts designed for applications where miniaturization, complex geometry, and material performance are critical. They serve as essential building blocks in advanced technology and medical devices.
- Medical & Surgical Devices: Components for minimally invasive surgical tools (articulating joints, micro-gears), implantable device housings (pacemaker clips, neurostimulator parts), and micro-fluidic connectors.
- Micro-Optics & Photonics: Precision mounts for lenses, fibers, and lasers, alignment pins, aperture plates, and shutter blades for optical assemblies and sensors.
- Electronics & Connectors: Micro-pins for high-density connectors, RF shielding cans, miniature heat sinks, and springs/contacts in consumer electronics, telecommunications, and semiconductors.
- Watchmaking & Precision Mechanics: Gears, pinions, bridges, and screws for mechanical watches and high-precision instruments.
- Aerospace & Defense: Miniature actuators, sensor components, and guidance system parts requiring reliability in small form factors.
Product Description
We specialize in the design and manufacture of micro and miniature metal components using high-precision CNC milling and turning of 304 and 316L stainless steel. Our capability focuses on producing parts with features measured in microns and overall dimensions often under 10mm.
Working with these materials, we achieve exceptional dimensional accuracy, surface finish, and geometric complexity at a small scale. 304 stainless steel offers excellent general-purpose performance, while 316L provides superior corrosion resistance and biocompatibility for medical implants.
Our processes are optimized to overcome the challenges of micro-machining, such as tool deflection and heat management, enabling us to produce intricate features like thin walls, micro-holes, fine threads, and complex 3D contours with repeatable precision. These components are ideal for prototyping and production where miniaturization cannot compromise part integrity or function.
