| 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). |
