Medical Device Prototype Development Partner for Functional Plastic Enclosures

Multi-Material CNC Plastic Prototypes with DFM Review, Assembly Validation, and Cosmetic Finishing

YS Precision supports medical device companies, healthcare product developers, and engineering teams with complete prototype development solutions.

We help customers transform early-stage product designs into functional prototypes through:

• Plastic CNC prototyping
• Engineering design review
• DFM analysis
• Multi-material manufacturing
• Surface finishing
• Prototype assembly validation

For this project, YS Precision manufactured a complete medical equipment housing prototype system based on customer-provided:

• 3D CAD models
• 2D engineering drawings
• Product requirements

The project involved approximately:

60 individual components

including:

• ABS plastic housing parts
• PC components
• Nylon mechanical parts
• Silicone sealing elements
• Functional buttons

Approximately:

50 prototype sets

were manufactured and delivered to a European medical equipment company for product validation.

Project Highlights

From Medical Device Design Concept to Functional Prototype

Medical device development requires more than producing individual parts.

Engineering teams need prototypes that allow them to evaluate:

• Product structure
• Assembly performance
• User interaction
• Appearance quality
• Manufacturing feasibility

YS Precision works as an extension of customer engineering teams, providing support from:

Design Review → Prototype Manufacturing → Assembly Validation → Product Improvement

This approach helps customers identify potential issues before moving into:

• Injection molding
• Tooling development
• Mass production

DFM Review Before Plastic Prototype Manufacturing

Before manufacturing started, YS Precision performed a detailed Design for Manufacturing (DFM) review.

Our engineers analyzed the product design including:

Assembly Structure

Reviewing:

• Component interfaces
• Assembly sequence
• Potential interference problems

Plastic Part Design

Checking:

• Wall thickness
• Structural strength
• CNC machining feasibility

Manufacturing Process

Evaluating:

• Suitable materials
• Machining methods
• Surface finishing requirements

Through early engineering communication, we help customers reduce:

• Design risks
• Prototype modification cycles
• Development time

Multi-Material CNC Plastic Prototyping Capability

Medical equipment often requires different materials for different functions.

This project included multiple engineering materials:

ABS CNC Machined Parts

Used for:

• Main housings
• Exterior covers

Advantages:

• Excellent machining performance
• Smooth cosmetic surface
• Good painting capability

PC Plastic Components

Used for:

• Functional structural areas

Advantages:

• High impact resistance
• Good dimensional stability

Nylon Prototype Components

Used for:

• Mechanical parts requiring strength and durability

Advantages:

• Wear resistance
• Good mechanical performance

Silicone Components

Used for:

• Sealing elements
• Flexible buttons
• User-contact areas

YS Precision manages multiple material requirements within one project, providing a complete prototype development solution.

Functional Medical Device Prototype Manufacturing

Unlike appearance-only models, this project required functional prototypes suitable for engineering evaluation.

The prototypes were manufactured for:

• Assembly testing
• Structural verification
• Design improvement
• Product demonstrations

YS Precision focuses on producing prototypes that are close to the final product in:

• Structure
• Appearance
• Assembly behavior

Cosmetic Finishing for Medical Equipment Prototypes

Medical products require professional appearance quality.

This project included:

Polishing

Improving:

• Surface smoothness
• Cosmetic appearance

Spray Painting

Providing:

• Uniform color
• Professional finish

Silk Screen Printing

Adding:

• Product labels
• Interface markings
• Brand elements

The finishing process allows customers to evaluate the prototype as a near-production product.

Prototype Assembly Validation

One of the most important steps in medical product development is confirming that all components work together.

YS Precision performed prototype assembly verification including:

• Housing assembly
• Silicone part integration
• Component alignment checking

The assembly process helped identify:

• Fit problems
• Interference issues
• Design improvement opportunities

before production tooling investment.

Low Volume Medical Device Prototype Production

This project required: 50 complete prototype sets

Low-volume prototype manufacturing is commonly required for:

• Medical device startups
• Healthcare equipment companies
• Product development teams

Typical applications include:

• Engineering validation
• Functional testing
• Clinical demonstration
• Product certification preparation

YS Precision supports customers through:

Prototype → Validation → Small Batch Production
