Guyson publishes finishing newsletters

Guyson International has produced two new finishing newsletters highlighting the benefits it can bring to a variety of component manufacturers in the medical sector.

One newsletter covers Guyson's blast finishing products and the other covers its spray wash and ultrasonic-cleaning products.

Both are available on request from the company's customer service department in either PDF or hard-copy formats.

The surface preparation and treatment newsletter introduces the topic of maintaining surface topographic control, which is a key attribute of medical devices and instruments.

It further explains how a consistent surface finish, measured typically in amplitude parameters such as Ra or Rz, must be maintained within specific statistical control limits to achieve surface-finish consistencies.

The newsletter introduces the Multiblast RXS400, which has been designed for the work-cell manufacturing environment such as medical implant and instrument production.

This type of machine is typically quick to set up and the blast parameters can be stored in a menu system for later recall to aid consistency of product-surface topography.

Robot load or robot gun manipulation and post non-contacting surface finish measurement options are available.

This system is ideal for companies that already possess manual blasting and that want to improve surface preparation consistency while increasing throughput.

The newsletter also features the Guyson Mediblast range of stainless-steel blast cabinets, which has been engineered for medical product manufacturers and laboratories in which the introduction of ferrous contamination would be detrimental to production.

Also introduced is a bench-top blast cabinet that is suitable for dental labs and hospital departments involved in prosthetic repairs.

The 'Euroblast Select - variable height' and the Euroblast SBP4 are sit-down manual-blast cabinets that optimise operator comfort and productivity when blasting for extended periods.

Both allow operators to perform for longer periods of time with minimum levels of fatigue.

A foot-pedal operated blast-control leaves both hands free for component manipulation.

The medical-cleaning newsletter features the Microclean multi-stage ultrasonic aqueous wash system, which is suitable for applications including prosthetic implants manufactured in stainless steel, titanium or other alloys.

This system is suitable for high-volume manufacturers, but smaller precision cleaning and passivation systems are also available for manufacturers with lower volumes.

The newsletter also shows the Microsolve cleaning systems, which are used for precision stain-free cleaning of medical/optical lens components to remove any traces of airborne dust, machining oil residues and finger prints from the optics prior to anti-scratch vacuum-coating processes.

The Microsolves are suitable for removing silicone oil from nasal intubation tubes in clean-room environments.

Guyson's Kerry Microsolve systems use 3M Novec HFE (hydrofluoroether) or HFC (hydrofluorocarbon), which do not contain chlorine, do not deplete the ozone layer and are compatible with SED regulations.

Guyson's Kerry ultrasonic baths and tanks are suitable for high-quality precision cleaning.

All can deliver quality cleaning benefits to the medical-instrument manufacturer.

The Formula 750 hot power-washer uses safe aqueous cleaning technology.

It can replace the potentially harmful trichloroethylene in a medical-component cleaning process.
