Summary

Rainbow Ultrasonics Ltd, based in Royston, UK, is a small, active company established twelve years ago. With a single employee and £318,677 in assets, it's a solo-founded operation overseen by two directors. The company holds a stellar 5.0 Google rating based on one review. It’s an irregular importer, primarily dealing in electrical machinery and equipment, with its last import activity occurring over two years ago.

The company’s website reveals a fascinating dual focus. While officially described as operating in dormant company industries, Rainbow Ultrasonics is actually a leader in ultrasonic welding, cutting, and processing solutions for the medical industry. They design and develop bespoke plastic joining and cutting technologies, offering everything from custom tooling to full-scale production equipment. They even operate a Class 7 Clean Room for verification and validation. Beyond medical applications, they also distribute Oxira air purification units, leveraging ultraviolet (UVC) technology.

Financially, Rainbow Ultrasonics Ltd presents a mixed picture. Current assets increased by 78% to £320,000, while net current assets liabilities rose by 58% to £260,000. Cash bank on hand, however, declined by 21% to £47,000. Creditors increased significantly, jumping 280% to £62,000, and trade creditors ballooned by 1500% to £19,000. Debtors also saw a substantial increase, rising 130% to £270,000. The company’s small size (meeting two of three criteria for a small company) allows for agility, but the increase in creditors and the decrease in cash reserves suggest it may be burning through money. As a small company, it’s exempt from an audit, so the figures are unaudited. It's not clear if the Oxira distribution is a new venture or a long-standing side project, but it appears to be a growing area of focus.
