These precision machining tracks share similar processes, materials, and quality standards.
Common materials include 304/316L stainless steel (industrial sensors), aluminum 6061-T6 (lightweight/automotive), titanium Grade 2 (chemical/medical), and PEEK/Delrin (non-metallic/high-purity). Material selection depends on the sensing environment, temperature range, and chemical exposure. We advise on material selection during quoting.
We machine O-ring grooves for static face seals, radial O-ring pockets for piston sealing, gasket surfaces for EMI/EMC gaskets, and hermetic seal pockets for glass-to-metal seal (GTMS) feedthroughs. For IP67/IP68 enclosures, we machine tongue-and-groove joints with O-ring channels. Leak testing is available on request.
Yes. We machine internal threads from M3 to M80 and larger, including metric fine, UN/UNF, BSPP, and NPT threads for sensor mounting and cable gland ports. We also machine optical windows with retaining ring threads. All threads are gauged with calibrated Go/No-Go gauges.
Standard tolerances: ±0.01mm on critical locating diameters, ±0.05mm on overall dimensions, and ±0.05mm on depth of internal features. For sensor alignment bores, we hold concentricity within 0.02mm True Position. Our Zeiss CMM verifies all GD&T callouts on the drawing.
Yes. We offer fiber laser marking for serial numbers, date codes, 2D Data Matrix codes (ECC200), logos, and customer part numbers. Laser marking is permanent and suitable for industrial and medical environments — no ink, no wear. Marking depth and contrast are verified per customer specification.
Absolutely. We prototype sensor housings in as little as 3-5 working days, with no minimum order quantity. Single-piece prototypes and small batches (2-50 pieces) are our specialty. We provide DFM feedback to optimize housing design for cost-effective production at higher volumes.
Stainless steel 304 or 316L provides durability and corrosion resistance for harsh environments. For applications needing magnetic transparency, aluminum 6061 or brass are better options.
Sensor alignment directly affects measurement accuracy. We recommend ±0.02mm on mounting bore positions and ±0.01mm on sensor pocket depths for consistent signal performance.
IP67 or IP68 rated sensor housings require precision O-ring grooves. TruPart machines gland depths to ±0.05mm with smooth groove floors to ensure reliable sealing over the product lifespan.
Straight vs. right-angle cable exits affect installation clearance. Design the cable gland thread early — M12x1.5 and PG9 are common standards we machine daily for sensor housing applications.
Hard anodizing on aluminum or electropolishing on stainless sensor housings prevents galling on threaded connections and resists corrosion in outdoor or washdown environments.
