Medical and health-screening equipment often combines electronics, sensors, displays, printers, structural components, and user-facing interfaces in a single enclosure. That makes enclosure manufacturing more than an appearance-driven exercise. The housing must provide structural support, accurate openings, reliable component positioning, serviceability, and a finish suitable for repeated public use.
This project involved medical device enclosure manufacturing for a self-service health screening workstation designed to integrate a large display, receipt printer, forehead temperature detection, facial recognition, blood oxygen measurement, and an external blood pressure module. The equipment was intended for health screening environments such as enterprises, airports, airlines, and other public or institutional locations.
At Zhongrongda, we manufactured the complete enclosure system using a combination of ABS, SPCC cold-rolled steel, and acrylic. Our Engineering Team had to coordinate CNC-machined ABS panels, a welded sheet-metal frame, an acrylic functional interface panel, surface finishing, and final assembly.
The project required us to balance appearance, dimensional accuracy, structural strength, component access, and manufacturability rather than treating the enclosure as a simple cosmetic shell.

Customer Requirements
The workstation needed to house multiple electronic and sensing components while remaining easy to assemble, maintain, and operate.
The internal SPCC steel frame had to provide sufficient structural support for the touchscreen display, thermal printer, temperature sensor, facial recognition camera, blood oxygen module, control board, power supply, and related electronics.
The ABS housing required accurately positioned openings for the display, camera, printer outlet, temperature detection module, facial recognition system, and blood oxygen interface. The workstation also needed a dedicated interface for an external blood pressure measurement unit.
From a service perspective, the enclosure was designed as a detachable structure. This allowed technicians to access the display, printer mechanism, sensors, and internal electronics during assembly, debugging, maintenance, and consumable replacement.
Appearance was equally important. The customer required a predominantly white enclosure with a clean, integrated appearance, rounded edges, uniform seams, and an inset acrylic interface panel. The finished housing also needed to tolerate routine cleaning and disinfection associated with public-use equipment.
The acrylic panel incorporated engraved and screen-printed functional labels, including areas for temperature detection, receipt printing, and blood oxygen measurement.
Manufacturing Challenges
1. Multiple Functional Openings
The enclosure contained numerous openings located across curved and assembled ABS components. Small positional errors could affect the fit of displays, sensors, printer mechanisms, and interface components.
We therefore treated the opening layout as an assembly requirement rather than simply a machining requirement.
2. ABS and Acrylic Fit
One of the most important challenges was controlling the relationship between the ABS housing and the inset acrylic panel.
The acrylic had to sit securely inside the housing slot without excessive clearance, interference, lifting, or uneven gaps. We paid particular attention to the machining dimensions of the acrylic, the ABS mounting groove, and the final painted dimensions.
3. Large Integrated Base
The large one-piece base platform combined a substantial ABS structure with multiple assembled components. CNC machining, bonding, filling, sanding, and painting could introduce dimensional changes or visible deformation.
The process therefore required controlled machining and progressive surface preparation rather than relying on a single finishing operation.
4. Internal Structural Integration
The SPCC frame had to support the equipment while leaving adequate space for wiring, electronics, heat dissipation, assembly, and future maintenance.
This meant the enclosure structure and internal frame had to be considered together.
5. Surface Quality
The finished ABS housing was required to have a smooth white painted surface without dents, scratches, obvious machining marks, or uneven seams.
For a public-facing health screening device, cosmetic defects are particularly noticeable, so surface preparation became an important part of the manufacturing process.
Our Engineering Solution
At Zhongrongda, our Engineering Team approached the project through a combination of DFM review, process planning, machining control, fixture considerations, and inspection.
During the DFM stage, we reviewed the relationship between the ABS housing, SPCC frame, acrylic panel, and equipment interfaces. We paid particular attention to the locations where separate components had to work together during final assembly.
For the ABS components, we planned CNC machining around the external geometry, screen window, printer opening, sensor interfaces, and acrylic mounting features. Multiple prototype pieces were then assembled and adjusted to achieve the required fit.
The SPCC frame was laser cut, CNC bent, welded, corrected, and ground. Welding deformation was controlled before the frame moved to surface preparation and coating.
For the acrylic panel, CNC machining was used to produce the external profile and positioning features. The functional markings were engraved and screen printed after machining.
Our manufacturing team also used progressive sanding and surface preparation on the ABS housing to reduce CNC tool marks and visible seams before painting. The final coating process included ABS-compatible primer and white gloss paint.
