Cleanroom-Ready Machines for Safe and Scalable Production

Contexo develops cleanroom-compatible assembly systems designed for high-volume medical device manufacturing — whether producing 800,000 diagnostic kits or 1.2 million insulin doses per day.

All systems are built in accordance with international medical standards and certified cleanroom regulations. Using standardized modular platforms, Contexo’s machines handle for example assembly, sealing, welding, stamping, inspection with maximum precision and flexibility. To ensure cleanliness during assembly, all stations are encapsulated and free of corners, edges and dead spaces. The minimal footprint and individual customer layouts are also taken into account to minimise clean room production costs. Up to 65 production stages can be integrated in one assembly machine.

Each solution can be customized to integrate laser processes and other manufacturing steps, ensuring smooth automation across all product lines. Intelligent process control guarantees consistent quality, repeatable performance, and long-term operational stability.

Laser-Integrated Assembly Systems for Medical Devices

Contexo specializes in laser-integrated assembly machines that combine advanced laser processing with high-precision automation. These systems are used for safety syringes, nasal spray devices, child-resistant closures, droppers, and syringe systems.

By collaborating with all major laser manufacturers, Contexo designs customized laser solutions that fit perfectly into existing production environments. From concept and process development to validation and commissioning, every project is managed with clear communication and on-time delivery.

Integrating laser technology increases manufacturing flexibility, enhances product quality, and enables cost-efficient production — helping medical manufacturers bring new devices to market faster and more reliably.

Continuous Motion Technology for Needle Shield Assembly

As the global demand for prefilled syringes rises, so does the need for high-quality needle shields. Contexo’s continuous-motion needle shield assembly machine offers maximum efficiency, speed, and stability for large-scale production.

At its core, the system features dual synchronized central towers that assemble and crimp with exceptional accuracy. This continuous-motion design delivers high output rates while maintaining robust, repeatable processes — essential for reliable medical production.

Contexo’s standardized machine platform allows for rapid configuration for rigid or soft needle shields, ensuring scalable automation solutions that can adapt to evolving product requirements.

Long Lifespan, Low Maintenance, and Flexible Design

Contexo assembly machines are engineered for durability, precision, and ease of maintenance. Their mechanical components guarantee years of smooth operation with minimal downtime. 100% inline vision inspections guarantees zero defects.

Built from stainless steel and fully encapsulated parts, the systems are optimized for hygienic cleanroom environments. All surfaces are easy to access and clean, simplifying daily operation and reducing maintenance costs.

Thanks to their compact, space-saving layout, Contexo machines enable cost-effective cleanroom production. Their modular structure allows easy adaptation to new products or changing requirements — ensuring long-term usability and high return on investment.

GMP Compliance and Complete Qualification Services

In the medical device industry, adherence to GMP (Good Manufacturing Practice) is essential. Contexo provides comprehensive GMP-compliant qualification for all systems and processes, meeting FDA and ISO standards.

Customers receive a complete qualification package (DQ, IQ, OQ) including documentation, testing, and log generation. Every project follows a fully validated process, ensuring full traceability and quality assurance throughout the product lifecycle.

With its deep understanding of regulatory frameworks and technical validation, Contexo ensures that each assembly system delivers certified reliability and compliance with global standards.

Fast Project Execution and Time-to-Market Advantage

Contexo stands out for its short project times and efficient implementation process.

“Contexo is well prepared and provides companies with its full range of experience,” says Matthias Müller, Contexo’s CCO. “We are ready to go — our systems can be deployed very quickly.”
