From initial concept and development through to final assembly and packaging, we provide complete end-to-end manufacturing support for our medical customers. By leveraging advanced plastic welding technologies, we enhance product durability, structural integrity, production efficiency, and overall device functionality.

Our commitment to quality, technical excellence, and responsive customer support enables us to deliver bespoke solutions tailored specifically to the demanding requirements of the medical industry — ensuring confidence and reliability at every stage of production.

MILITARY & AEROSPACE SECTOR

We have spent many years developing and delivering advanced plastic joining, sealing, and cutting technologies for the assembly of highly specialised, reliable, and mission-critical military and aerospace products.

Our extensive knowledge of plastic welding equipment within the defence and aerospace sectors enables us to provide expert guidance, precision tooling, and flexible production solutions across a wide range of essential equipment used daily in the field.

Applications include battery enclosures, communication devices such as radios, and full-face respiratory masks with integrated filtration systems. Through robust engineering and advanced welding technologies, we help ensure these products meet the highest standards of durability, performance, and operational reliability — supporting those who rely on them in critical environments.

CONSUMER PROJECTS

With many years of experience developing and providing advanced plastic joining, sealing, and cutting technologies, we support the manufacture of a wide range of everyday consumer products — the items people use every day without ever asking, “How was this made?”

Our extensive expertise in plastic welding equipment enables us to offer expert advice, precision tooling, and flexible production solutions across the consumer goods sector. This spans an exceptionally broad range of products, from baby nappies and adult razors to food and cake cutting systems, household appliances, and countless other items found in daily life.

Through innovative plastic joining technologies, we help manufacturers improve product durability, efficiency, and quality — ensuring the everyday items people rely on are produced safely, reliably, and at scale.

ON-SITE SUPPORT

In addition to providing machines, tooling, trials, and product development, we offer full support both on-site and in-house throughout every stage of installation, production, and development.

Our team can assist in person with machine and tooling setup, calibration, and maintenance, ensuring your systems operate smoothly from day one. We also provide remote support, including virtual guidance and phone-based troubleshooting, to answer questions and resolve issues quickly as they arise.

With Rainbow, you have a partner dedicated to keeping your processes running efficiently and reliably at every stage.

CONSULTANCY SERVICES

We provide expert guidance on part design, including energy directors, weld geometry, and other critical plastic joining requirements. With decades of experience, we are happy to share our knowledge to help you design parts that meet your specific welding and performance needs.

Our team can also conduct full trials and testing, generating early weld data and identifying any adjustments required. This ensures your parts are optimised for production and ready to move confidently to the next stage of manufacturing.

BESPOKE SOLUTIONS

At Rainbow Medical and Ultrasonics, we design and manufacture all tooling and special-purpose machinery in-house using advanced 3D CAD systems and our fully equipped CNC toolroom. This gives us complete control over quality, precision, and delivery for everything we offer.

Our in-house capabilities include trials, design development, tooling modifications, and support with early-stage prototype and welded part design. We also provide small- to medium-scale production on-site, helping you move your projects forward quickly, efficiently, and with confidence.
