Processing Customized 304 Stainless Steel CNC Milling Hollow Metal Shell
These are precision-machined, ventilated or styled metal housings designed to protect sensitive internal components in medical and laboratory equipment, while providing necessary airflow, visibility, or aesthetic design.
Medical Electronic Devices: Ventilated enclosures for portable monitors, infusion pump controllers, ultrasound transducers, and handheld diagnostic scanners that require EMI shielding and heat dissipation.
Laboratory & Diagnostic Equipment: Perforated side panels or access covers for analyzers, centrifuges, DNA sequencers, and incubators to allow for airflow while maintaining structural integrity and a professional appearance.
Sterilization & Surgical Equipment: Baskets, trays, or casing components for autoclaves, instrument washers, or surgical light handles featuring drainage or ventilation holes.
Wearable Medical Devices: Rigid, breathable external chassis for advanced prosthetic limbs, rehabilitation exoskeletons, or durable external sensor housings.
Medical Device Prototyping: Functional and aesthetic enclosures for proof-of-concept devices and pre-production units.
We specialize in fabricating complex, perforated or (openwork) metal enclosures from 304 stainless steel using high-precision, multi-axis CNC milling. This process involves machining a solid block of material to create a unified shell with integrated precisely patterned cut-outs, ventilation grids, logo cutouts, or decorative openwork designs. Unlike sheet metal fabrication, CNC milling from solid stock allows for the creation of true 3D contours, integrated mounting bosses, and complex internal features alongside the pattern, all in a single, rigid piece. This results in a highly durable, cleanable, and professional enclosure with excellent structural integrity. 304 stainless steel provides ideal corrosion resistance, strength, and a hygienic surface for medical environments. We offer end-to-end service from design optimization for manufacturability (DFM) through to final finishing and inspection.
| Category | Parameter | Details / Specification |
|---|---|---|
| Base Material | Material | AISI 304 Stainless Steel (Plate or Block, UNS S30400) |
| Material Form | Precision ground plate or solid block. Thickness defines enclosure depth. | |
| Key Properties | Excellent corrosion resistance, good strength-to-weight ratio (when), biocompatible surface, sterilizable. | |
| Design & Geometry | Primary Feature | Integrated(Openwork) Pattern – holes, slots, grids, or custom designs machined through the enclosure walls. |
| Envelope Size (Max) | Up to 500 x 400 x 150 mm (LxWxH) – subject to machine capacity. | |
| Minimum Web/Feature Size | 1.0 mm for remaining solid sections betweenfeatures (design dependent). | |
| Pattern Types | Round holes, hex holes, slotted vents, custom artistic patterns, logo cutouts. | |
| Pattern Tolerance | Hole/slot position within ±0.05 mm. Pattern consistency across the part. | |
| Manufacturing & Precision | Core Process | 3+2 Axis or 5-Axis CNC Milling. Utilizes small-diameter end mills for finefeatures. |
| Wall Thickness | Minimum practical wall thickness: ~1.5 mm for structural integrity post-machining. | |
| Dimensional Tolerance | Overall enclosure dimensions: ±0.1 mm. Critical mating/interfacing features: ±0.05 mm. | |
| Flatness/Parallelism | Critical for sealing surfaces, typically held within 0.1 mm over the span. | |
| Surface & Finish | As-Machined Finish | Visible tool marks from milling. All edges deburred. |
| Standard Finishes | Satin Brushed, Bead/Sand Blasted (Matte), Vibratory Polished. | |
| Premium Finishes | Mirror Polishing, Electropolishing (for enhanced corrosion resistance and cleanability). | |
| Coatings | Powder coating or PVD coating for color and additional protection (applied post-machining). | |
| Secondary Operations | Common Add-ons | Tapped holes for assembly, EMI shielding gasket grooves, integral hinges or latches (machined features), laser etching for labels/logos. |
| Quality & Compliance | Inspection | 100% visual inspection for defects. Dimensional verification of critical features via CMM. |
| Cleanliness | Thoroughly cleaned to remove all machining coolant and metallic debris. | |
| Documentation | Dimensional inspection report, material certification. Can support FDA Design History File requirements. | |
| Standards | Suitable for devices requiring compliance with IEC 60601-1 (safety) and ISO 13485 (quality management). |
