Medical Device Prototypes: High Precision, Cleanliness, and Biocompatibility
The medical device industry has extremely strict requirements for product precision, cleanliness, and biocompatibility. During the new product development phase, functional verification, assembly testing, and clinical simulation through prototypes can significantly reduce later registration and mass production risks. Dongguan Yiruida Technology Co., Ltd. provides professional prototype manufacturing services for medical device companies, following the ISO13485 quality management concept, and supports the entire process from concept validation to small batch trial production.
Types of Medical Device Prototypes We Can Make
- Diagnostic Equipment: External housing of in vitro diagnostic instruments, test card brackets, reagent kit components
- Surgical Instruments: Surgical forceps handles, orthopedic guides, minimally invasive instrument grips
- Rehabilitation Equipment: Orthotic parts, walking aid connectors, rehabilitation training equipment housings
- Implant Trial Parts: Orthopedic plate prototypes, dental implant models (used only for appearance and assembly verification)
- Medical Electronics: Monitor housing, ultrasound probe handles, medical power mounting bases
Applicable Materials and Requirements
| Material | Features | Typical Applications |
|---|---|---|
| Medical Grade ABS | Resistant to disinfectants, paintable | Instrument housings, panels |
| PC (Polycarbonate) | High transparency, impact resistance | Viewing windows, transparent housings |
| POM (Acetal) | High rigidity, wear-resistant | Gears, sliding mechanisms |
| Stainless Steel (304/316L) | Corrosion-resistant, sterilizable | Surgical instrument handles, brackets |
| Aluminum Alloy | Lightweight, oxidizable | Internal structural brackets |
| High-Temperature PU (Molding) | Simulates PC/ABS | Small batch trial production parts |
Note: For parts that directly contact the human body or are implanted, please confirm the material compliance. We can provide material certificates and traceable documents upon request.
Process Selection Recommendations
| Quantity | Recommended Process | Advantages |
|---|---|---|
| 1-10 pieces | CNC Machining (Plastic/Metal) | High precision, real materials, functional testing |
| 10-50 pieces | Vacuum Molding (PU) | Low cost, similar appearance to mass production |
| 50-200 pieces | Molding or multi-cavity molds | Small batch supply |
| Functional Test Pieces | CNC Metal | Real mechanical properties |
Quality Control and Documentation

- Complies with ROHS, REACH requirements (as per customer needs)
Typical Application Cases
1. Housing of In Vitro Diagnostic Instruments
A medical technology company needed 10 sets of instrument housings for clinical testing. They used CNC machining of medical-grade ABS, with spray painting and logo screen printing, and applied a fingerprint-resistant coating. The delivery time was 7 working days, and the prototype successfully passed hospital trials.
2. Functional Prototype of Surgical Forceps Handle
A surgical instrument factory needed to verify the grip feel of a new design. They used CNC-machined 316L stainless steel handles, followed by brushing and passivation, and provided three units for doctors to test. Based on feedback, the design was quickly modified, avoiding mold rework.
3. Small Batch Trial Production of Rehabilitation Braces
A rehabilitation equipment company needed 50 sets of brace connectors for limited patient trials. They used vacuum molding production, with the material being disinfectant-resistant PU resin, costing only one-third of CNC machining, with a delivery time of 5 days.
