Custom CNC Machining Stainless Steel Sensor Housings
Precision enclosures for automotive, industrial, aerospace, and medical sensors — machined from metal for durability, EMI shielding, and environmental protection.
- Aluminum
- Stainless Steel
- Titanium
- ±0.01 mm tolerance
Metal Sensor Housings
We machine sensor housings from solid metal stock — no casting, no welding, just precision CNC from bar or block.
CNC Turning
Single‑setup turning of cylindrical housings — bores, threads, sealing faces, and O‑ring grooves with ±0.01 mm accuracy.
- Concentricity guaranteed
- H7/g6 fits
- NPT / G / M threads
CNC Milling
Flanges, mounting holes, side ports, non‑cylindrical features, and complex cavities — all machined in one or two setups.
- Thin‑wall capability
- Sealing surfaces
- Bosses & standoffs
Precision Boring
Internal bores for sensor probes, bearings, and bushings with extreme roundness and surface finish (Ra ≤ 0.4 μm).
- Ø2 – Ø200 mm range
- Sub‑micron roundness
- Press‑fit ready
- Post‑processing: Clear anodizing, hard anodizing (Type III), black anodizing, and light bead blasting.
Materials We Work With
Select from a wide range of metals — each chosen for its specific performance in sensing environments.
Aluminum Alloys
6061 · 7075 · 5052
Lightweight, excellent thermal conductivity, and natural EMI shielding. 7075 offers near‑double strength for demanding applications.
- Anodizing available (clear/black/hard coat)
- Good machinability
- Ideal for weight‑sensitive sensors
Steel & Stainless
303 · 304 · 316L · 17-4PH
Corrosion‑resistant, high strength, and excellent for harsh environments. 316L preferred for marine, medical, and chemical.
- Salt spray resistant
- High pressure capability
- Passivation available
Titanium & Specialty
Ti‑6Al‑4V · Hastelloy · Inconel
Titanium for aerospace/medical where strength‑to‑weight and biocompatibility matter. Hastelloy/Inconel for extreme heat or corrosive media.
- Highest strength‑to‑weight
- Biocompatible options
- Extreme temperature capability
Surface & Protection Finishes
From powder coating to anodizing, we offer a range of finishing processes to improve part performance and appearance.
Passivation
Removes free iron from stainless steel surfaces — restores corrosion resistance after machining.
Type II (clear/color) and Type III hard coat for aluminum. Adds wear resistance and corrosion protection.
Mechanical Finishes
Bead blasting, brushing, polishing, and laser engraving — achieve the exact surface texture and branding.
Nickel plating, zinc plating, and electroless nickel for steel and copper alloys — adds hardness and corrosion resistance.

Inspection & Testing
Every sensor housing is inspected and tested to ensure it meets your specifications — from material to final sealing.
Dimensional Inspection
CMM, optical comparators, and bore gauges for 100% critical dimension verification. Tolerances down to ±0.01 mm.
Surface & Thread Profiles
Profilometers for Ra/Rz on sealing surfaces. Thread gauges for NPT, G, and Metric profiles — full GO/NO‑GO inspection.
Corrosion & Environment
Salt spray (ASTM B117), humidity cycling, and thermal shock tests — available for automotive and outdoor applications.
Material Traceability
Mill test reports (MTR) for every batch. RoHS, REACH, and conflict‑mineral compliance documentation available.
