RDX Coating System

The RDX Coating System from Harland Medical Systems is a development/pilot production scale, economical coater for applying ultraviolet cured medical device coatings. Available in two models, the RDX coaters integrate both dip coating and curing in one compact unit.

RDX Series Coaters are ideal for coating catheters, guidewires, introducers, and similar medical devices. The modular construction means you can select from pre-engineered feature packages and automation options you need for your particular application without the long lead times and high costs associated with custom designed equipment.

A servo controlled motion column lowers a cassette of devices into individual solution tubes. These tubes are removable and disposable to help keep coating solution fresh. You program the immersion speed, immersion distance and extraction speed that is right for your device and coating chemistry. The J-shaped solution tubes allow you to coat long devices without the need for unusually high ceiling clearance. The deck of solution tube openings can be configured to a height convenient for your device length. And for coating shorter lengths a Straight Dip configuration can be used.

A Dual Solution option accommodates two separate solutions for those coating technologies requiring two unique fluids.

Cure Process

The UV Cure Sources produce a flood of the proper spectrum UV light to cure today’s coating chemistries. To assure uniform cure, the parts individually rotate in front of the UV sources. Each source can cure 25 cm of part length. Sources can be added into pre-wired compartments to coat up to 170 cm of device length. An automatic cover closes over the solution tube funnel openings to protect light-sensitive coating solution from UV exposure during curing.

A mechanical shutter opens and closes for precise control of cure time. When this shutter is closed and no curing is underway, UV sources can be reduced to standby power to conserve energy and extend bulb life.

CoatingWorks™ Software

The versatile, intuitive Harland CoatingWorks software helps you program each operation of the RDX coater. Coater actions are selected from a menu and added to the coating sequence. These protocols can then be stored in memory for future use. After programming, firmware takes over the actual operation of the coater. Program creation and editing are password protected.
