By combining our cleanroom injection molding capabilities with in-house engineering support and automated toolmaking systems, our team can help reduce supplier complexity while simultaneously expediting the development timeline and improving production efficiency.
From rapid prototyping and bridge tooling to high-volume manufacturing programs, Seaway Plastics can provide hands-on support throughout the complete lifecycle of medical products that demand stringent contamination control, repeatability, and regulatory-focused manufacturing practices.
ISO Class 7 & ISO Class 8 Cleanroom Injection Molding Services
ISO Class 8 Cleanroom Injection Molding
ISO Class 8 cleanrooms are required for a broad range of medical molding applications, including molded device housings, packaging components, fluid management products, and other medical devices that require controlled manufacturing conditions. These environments exchange air approximately ten to twenty-five times per hour and utilize filtration systems capable of removing airborne particles as small as 0.5 microns.
ISO Class 7 Cleanroom Injection Molding
For more contamination-sensitive injection molding projects or devices, Seaway Plastics also operates ISO Class 7 cleanrooms that feature significantly higher air exchange rates and enhanced particulate control capacity. These climate-controlled environments use HEPA filtration systems capable of removing airborne particles or contaminants as small as 0.3 microns while still delivering the tightly controlled production and assembly services required for advanced medical devices and diagnostic components.
Cleanroom Molding Equipment & Production Flexibility
Given the nature of medical devices and components, tremendous operational and production flexibility is required in a manufacturing partner to meet stringent requirements and parts or sub-assemblies with variable part sizes or volume requirements. Seaway Plastics operates cleanroom injection molding equipment ranging from 44 to 180 tons, allowing us to support everything from early-stage medical prototypes to scalable commercial production projects.
In addition to our thermoplastic molding services, we can also address needs for liquid silicone rubber (LSR) molding for medical applications that require flexibility, chemical resistance, and biocompatibility. This includes components used in fluid management systems, wearable devices, seals, and other precision medical products.
Our cleanroom molding capabilities include:
- Tight-tolerance rapid medical tooling
- Material and product traceability under ISO 13485 guidelines
- Vacuum systems with deionized air blasting
- Four-stage compressed air filtration
- Secondary finishing operations
- Complete cleanroom kit assembly
By consolidating all molding, inspection, assembly, and packaging services under one service provider, OEMs in the medical space can trust that strict protocols are adhered to throughout the production process. Seaway Plastics helps reduce unnecessary handling, simplifies the supply chain management process, and is a critical aspect of supporting faster production timelines for medical device manufacturers.
