Medical Injection Molding MedAccred-accredited processes for complex, validated medical devices

Not always. It depends on the device class and regulatory pathway. However, validation is typically required for parts used in Class II and III devices, or for any component directly involved in patient safety, dosage control, or critical performance.

Revalidation may be required if there are changes to the mold, material, equipment, or process parameters. Regulatory bodies or internal quality systems may also mandate periodic revalidation to ensure continued compliance.

No, they serve different purposes. Process validation confirms that the injection molding process consistently produces parts that meet quality and regulatory requirements. It involves steps like IQ, OQ, and PQ to establish and document process stability. Part approval, ensures the molded part itself meets all dimensional, functional, and performance specifications. This may include first article inspections, material verification, or biocompatibility testing. Both are essential in regulated medical manufacturing, but validation focuses on how parts are made, while approval focuses on what is made.

Medical OEMs are accountable for device safety and performance. IQ/OQ/PQ validation provides documented proof that the molding process is controlled, repeatable, and capable of producing compliant parts. It reduces risk, satisfies regulatory requirements, and helps speed up audits, market entry, and design changes.

Validation planning should start early, ideally during tool design. This allows time to integrate sensors, define critical-to-quality parameters, and align the process with regulatory goals. Early involvement avoids costly rework and ensures smoother FDA or notified-body approval.

Timelines vary based on part complexity, tooling readiness, and documentation scope. A typical validation from IQ through PQ may take 4–8 weeks. Your injection molding partner is the best source for determining timelines.
