Cleanroom and medical injection moulding companies play a critical role in the production of high-precision plastic components for use in healthcare and pharmaceutical applications. These companies are trusted to manufacture parts that meet the tight hygiene, quality, and regulatory standards, working within ISO Class 6 or ISO Class 7 cleanroom environments. From medical device housings to surgical components and diagnostic equipment, medical injection moulding companies and cleanroom injection moulders are relied upon to deliver consistent, traceable, and compliant products.
PlastikCity Partners – Medical & Cleanroom Injection Moulding Companies
Medical injection moulding companies typically specialise in working with medical-grade polymers such as polypropylene, polycarbonate, PEEK, and TPE. These materials are selected for their biocompatibility, sterilisation resistance, and mechanical properties. The moulding process is tightly controlled to ensure part integrity, with documentation and traceability systems in place to meet regulatory requirements such as ISO 13485. These moulders can produce single-use components or complex assemblies, supporting a wide range of medical applications. All-electric moulding machinery is favoured due to its increased cleanliness and precision.
Choosing the right medical or cleanroom injection moulding company is essential to ensure your components meet the required standards for cleanliness, precision, and regulatory compliance. You need to consider the company’s cleanroom classification (such as ISO Class 6 or 7), experience with medical-grade polymers and provable history within the sector. A reliable partner will also offer support with material selection, design for manufacturability, and validation processes, helping you avoid costly delays and ensure product safety from the outset.

Supporting Information
Medical injection moulding companies offer a precise and repeatable process used to produce plastic components for healthcare and pharmaceutical use. It involves injecting molten medical-grade plastic into a high-precision mould under controlled conditions, then allowing it to cool and solidify. The process is ideal for creating parts with precise specifications and intricate measures, such as diagnostic test casings, inhaler components, and surgical device housings. When carried out in a cleanroom, the process also protects against particulate contamination that could compromise product safety or regulatory compliance.
One of the main advantages of cleanroom injection moulding is its ability to maintain sterility and reduce contamination risks during production. This is particularly important for components used in invasive procedures or direct patient contact. Cleanrooms equipped to ISO Class 6 or 7 standards ensure filtered air, controlled humidity, and strict personnel protocols, all of which contribute to a stable and hygienic manufacturing environment. These conditions support regulatory approval and allow manufacturers to meet the quality standards expected in the medical sector.
In addition to cleanliness and precision, medical injection moulding companies and cleanroom injection moulding offer excellent scalability for both low and high-volume production. The process supports consistent part replication with minimal variation, which is vital for regulatory audits and ongoing quality assurance. Many cleanroom moulders also provide secondary services such as ultrasonic welding, assembly, and packaging within the same controlled environment, helping reduce handling and contamination risks. With the right partner, you gain access to a full-service solution that meets strict industry requirements while keeping production efficient and cost-effective.
