Customised Hospital Equipment Model Factory
Manufacturing Process for Hospital CT Scanner Scale Model
I. Material Selection Phase
Utilizing a multi-layer composite material approach:
Main Frame: CNC-machined from aerospace-grade 6061 sandblasted to Ra1.6 surface roughness
Gantry Ring: Thermally formed transparent acrylic with UV-printed cross-sectional imaging layers
Patient Table: Magnetic ABS rail system with counterweights to replicate realistic sliding resistance
Control Panel: Laser-engraved linen composite board with embedded LED backlit buttons
II. Core Production Process
1. Structural Fabrication
5-axis machining for main support brackets, preserving original bolt positioning holes
Gantry constructed via triple-layer lamination: frosted light-guide panel (inner), film-printed scan patterns (middle), anti-glare coating (outer)
PTFE lubrication strips installed on table rails for authentic movement resistance
2. Surface Detailing
Control knobs: Investment-cast zinc alloy with micro-bead blasting finish
Emergency stop button: Dual-shot molded with spring-loaded return mechanism
Cable ports: Hand-wrapped silicone wiring bundles, color-coded per medical standards (yellow/blue)
3. Painting & Weathering
Base coat: 3-layer electrostatic spray of DuPont medical-grade gray
Panel markings: Screen-printed with UV-cured ink
Wear effects:
Dry-brushed aluminum powder on high-contact rail surfaces
Airbrushed rubber wear patterns on foot pedals
Oxidizing fluid applied to simulate corner corrosion
III. Quality Control & Packaging
3D-scanned verification against source data (±0.3mm tolerance on critical dimensions)
Functional testing:
Table movement speed: 18cm/s ±5%
Gantry tilt angle deviation ≤1°
Shockproof packaging: CNC-milled EPP foam inserts with equipment positioning markers
Key Advantages
Developed through on-site research at medical OEM facilities, this process delivers:
1:1 replicated warning labels and operational interfaces
Removable housing to showcase internal mechanics
Optional DICOM image projection upgrade
