GWX Coating System

Harland Medical Systems presents the GWX Series Coating System for applying and curing ultraviolet and heat cured medical device coatings. The GWX coater integrates both dip coating and curing in one compact unit and is ideal for coating catheters, guidewires, introducers, and other similar medical devices.

The pre-engineered modules mean you can select the feature packages and automation levels you need for your particular application, without the long lead times and high costs associated with custom-designed equipment.

Dip Module

The GWX Series Coating Systems are designed to coat low column strength devices, such as guide- wires and small diameter catheters up to 180 cm in length. By raising the solution tubes up, the devices remain stationary and do not follow a bend, allowing them to remain straight in their strongest position. As the tubes rise, coating solution flows through the solution tubes to assist the parts into the solution. The dipping module then lowers at a precise rate to accurately apply the coating. And the coating solution is maintained at a constant level as solution is consumed while coating the parts.

Cure Module

The GWX coater can be equipped with an ultraviolet cure module, a heat cure module, or both. The cure module slides into position and surrounds your parts after dipping, so there is no need for a separate curing oven. The GWX can provide both heat and UV energy to supply whatever your coating chemistry demands. Heat or UV cure can be simply selected in the Harland CoatingWorks™ protocol creation program.

UV Cure
The UV Cure Module produces a flood of the proper UV wavelength light to cure today’s UV-cured coating chemistries. Cool operation of UV sources minimizes heat buildup and a built-in radiometer monitors UV intensity and sounds an alarm if intensity drops below a set level.

Heat Cure
The cure module can also provide heat for thermally cured coatings. Moving air helps maintain temperature from top to bottom.
