Precision Clean Room Injection Molding Design Services

Evok Polymers has extensive experience designing injection molded components for ISO Class 5 through Class 8 clean room environments (equivalent to Class 100 to Class 100,000 under Federal Standard 209E). Our design approach focuses on minimizing particle generation, optimizing material selection for low outgassing, implementing compliant mechanisms to eliminate wear debris, and ensuring parts can be effectively cleaned and validated. With our semiconductor and medical device background, we understand the specific contamination control requirements for various clean room classifications and design accordingly.

Our clean room design methodology incorporates multiple contamination control strategies: selecting ultra-pure, medical-grade materials with minimal outgassing; designing compliant mechanisms that eliminate particle-generating joints; optimizing mold design to minimize flash and improve cleanability; implementing proper venting to prevent trapped air and contamination; conducting rigorous molding trial reports with particle monitoring; and performing first article qualification with detailed inspection protocols. Our founder's experience developing $40 million in ultra-clean liquid delivery systems for semiconductor applications ensures proven expertise.

Material selection for clean room applications depends on your specific requirements, but we commonly work with medical-grade polycarbonate, ultra-pure polypropylene, PEEK, liquid silicone rubber (LSR), and other high-purity resins that meet USP Class VI, ISO 10993, or semiconductor-grade specifications. Our material selection process evaluates biocompatibility, chemical resistance, sterilization compatibility, outgassing characteristics, particle generation potential, and regulatory compliance to identify the optimal resin for your clean room environment and application.

Yes, Evok specializes in designing compliant mechanisms in collaboration with Studio Weber and Associates. Compliant mechanisms achieve motion through the deformation of flexible components rather than traditional hinges, bearings, or joints. This approach is ideal for clean room applications because it eliminates particle-generating wear points, reduces part count, simplifies cleaning validation, and improves reliability. Our Hinj design philosophy is organized around dematerialization and performance optimization through compliant mechanism research and development, making us uniquely qualified for ultra-clean applications.

Our New Part Development Pipeline typically progresses through five stages: Concept Feasibility (2-3 weeks), Alpha Research with prototypes and design iterations (3-4 weeks), Beta Development with single cavity tooling (4-6 weeks), Qualifications including molding trials and first article approval (2-3 weeks), and Product Launch preparation (1-2 weeks). Clean room projects may require additional validation time for contamination testing and protocol development. We emphasize speed to market through cross-functional collaboration while never compromising on the quality and cleanliness standards essential for your application.

Yes, we offer rapid prototype services specifically tailored for clean room applications. Prototyping allows you to validate design, fit, function, and material performance before committing to production tooling. We select prototyping processes that maintain cleanliness considerations and provide both cosmetic and functional verification. Our prototype services help identify potential contamination issues early, validate compliant mechanism performance, test material compatibility with cleaning protocols, and ensure parts meet your ultra-clean requirements before significant tooling investment.

Evok's analytical testing capabilities include mold flow analysis to optimize material flow and minimize contamination risks, tolerance analysis to ensure precision fits in clean room assemblies, particle generation testing during molding trials, outgassing analysis for semiconductor and medical applications, dimensional inspection with 30 points per critical dimension, and cleanliness validation protocols. Our team uses various analytical tools to solve problems and optimize part performance. We work closely with third-party testing laboratories when specialized clean room certifications or regulatory compliance testing is required.

Evok's pricing is transparent and project-specific. CAD design services start at $110/hour for engineering and part design. Prototype services range from $100-$300 per part depending on size and prototyping system. Production part pricing focuses on achieving the lowest cost per part while maintaining jewelry-quality standards—we're passionate about itemizing and prioritizing cost structure. We're very upfront with costs so you can contribute to optimized design decisions.
