Additionally, when working with our Medical Solutions Team, you’ll have access to a group fully dedicated to bringing your medical device to life, from concept to reality. From R&D to project management and production, our Medical Solutions Team can support you at every step of the process.

The Medical Solutions division ensures a customer-focused and personalized approach to every project in order to achieve the highest quality standards and meet customer deadlines.

The necessary clean room classification is determined by your product’s intended use, risk profile, and regulatory requirements. High-risk, implantable, or critical-path medical components usually require an ISO Class 7 environment, while lower-risk or non-patient-contact components may be suitable for ISO Class 8.

To determine the right classification, we assess your product’s clean room injection molding requirements, including material selection, exposure risk, downstream sterilization, and applicable regulatory standards. This makes sure the clean room environment is appropriate without adding unnecessary complexity or cost.

An effective injection molding clean room design is centered on contamination control and process stability. Key design features include:

• HEPA filtration systems to control airborne particles
• Positive air pressure to prevent contaminants from entering the clean room
• Controlled zoning and material flow to separate clean and non-clean areas
• Non-contaminating machinery and materials designed for medical manufacturing

These elements work together to maintain consistent environmental conditions and support reliable injection molding in clean room operations.

Yes. We manage the entire validation lifecycle for cleanroom molded components. This includes comprehensive documentation of:

• Installation Qualification (IQ)
• Operational Qualification (OQ)
• Performance Qualification (PQ)

These validation activities ensure that processes are controlled, repeatable, and compliant with relevant cleanroom injection molding standards, providing full traceability to support regulatory submissions and audits.

Yes. While both processes require controlled cleanroom environments, cleanroom LSR Injection Molding involves additional technical considerations. Liquid Silicone Rubber requires specialized metering and mixing equipment, along with precise control of temperature, pressure, and curing conditions.

Because LSR components are often used as seals, membranes, or flexible medical parts, even minor contamination can compromise performance. Maintaining a clean environment is therefore critical to preserving material integrity and ensuring consistent part quality.

Yes. Achieving tight tolerances is often a key factor for clean room precision injection molding. The controlled environment greatly reduces particulate contamination and process variability, both of which can affect dimensional accuracy.

Our clean room facilities are equipped with advanced tooling, process controls, and monitoring systems that enable the production of highly precise medical components, including parts that require micron-level tolerances.
