How It Works
Molten plastic is injected into a mold. The shape hardens into a precise medical part.
Importance in Healthcare
Medical products need strict standards. This process guarantees safety and accuracy.
2. Benefits of Medical Injection Molding
High Precision Production
Even the smallest details are accurate. Perfect for surgical tools and implants.
Cost-Effective Manufacturing
Mass production reduces costs. More products, less waste.
Biocompatibility
Materials used are safe for human contact. Ensures no harmful reactions.
Scalability
Production can be small or large. Adaptable to demand.
Fast Production Cycles
Automation speeds up manufacturing. Critical for urgent medical needs.
3. Role of a Mold Maker in Medical Injection Molding
Custom Mold Design
A mold maker creates precise molds. Designs fit medical specifications.
Material Selection Expertise
Choosing the right plastic is crucial. Biocompatible and durable materials are required.
Ensuring Tight Tolerances
Molds must be exact. Even minor defects can cause failure.
Long Mold Lifespan
A high-quality mold lasts for many cycles. Ensures consistent production.
4. Common Medical Products Made with Injection Molding
Surgical Instruments
Scalpels, forceps, and retractors need high precision.
Implantable Devices
Pacemakers, joint replacements, and stents use biocompatible plastics.
Diagnostic Equipment
Test tubes, sample containers, and lab trays require strict accuracy.
Drug Delivery Systems
Syringes, inhalers, and insulin pens must be defect-free.
IV Components
Valves, tubing, and connectors are mass-produced efficiently.
5. Materials Used in Medical Injection Molding
Thermoplastics
- Polycarbonate (PC) – Strong and impact-resistant.
- Polypropylene (PP) – Lightweight and chemical-resistant.
- Polyetheretherketone (PEEK) – High heat resistance.
Silicone Rubber
Flexible and biocompatible. Used in medical tubing.
Bio-Resorbable Polymers
Dissolve in the body over time. Used for sutures and implants.
6. Cleanroom Injection Molding
Why Cleanrooms Matter
Medical parts must be sterile. Contaminants can cause infections.
Types of Cleanroom Molding
- ISO Class 7 (10,000 particles per cubic foot)
- ISO Class 8 (100,000 particles per cubic foot)
Strict Hygiene Protocols
Workers wear protective gear. Machines are sterilized regularly.
