Leading industrial finishing equipment manufacturer Guyson International successfully exhibited equipment from their blast finishing and ‘Kerry’ branded ultrasonic cleaning ranges at the TCT + Personalize show, held at the NEC, from the 28-29th September 2016. This exhibition covers all aspects of 3D printing, additive manufacturing (AM) and rapid prototyping and Guyson were on Stand No. J26.

Showing for the first time at ‘TCT + Personalize’ was a variation of the Guyson Euroblast® 6SF blast cabinet which has been devised especially for the additive manufacturing (AM) market. These particular Guyson AM bead blast systems, the smaller Euroblast 4SF ‘AM’ was shown last year, are designed specifically for the Additive Manufacturing market where the blasting of Stainless, Aluminium, Titanium or Inconel built components is often undertaken as is often the case with aerospace and medical components. Some of these exotic materials have the potential to create explosive dust when blasted, so special provision is made with these Guyson blast systems to mitigate those risks.

The Guyson ‘AM blast systems’ can be specified with a variety of options that can be chosen from, depending on the level of perceived risk involved, options including: full earth braiding to the cabinet, gun, dust collector and hose and include ground nuts on all the main contact points to prevent any static spark generation and also anti-static fabric gauntlets to allows the operator greater flexibility when blasting whilst preventing media escape. Also externally located LED lighting, for good illumination of the blast area, so as to not create any chance of a spark within the blast chamber.

The Guyson AM blast cabinets are complemented with the new range of AM specified dust collectors, Guyson exhibited the mid-range C600-AM dust collector designed to accompany the Euroblast 6SF–AM which was also on show. Again conscious of the explosive potential of some of the materials that can be involved in additive manufacturing the C600-AM dust collector has a host of features and options to minimise risks including; explosion relief valve, explosion isolation valve, secondary HEPA filtration, waste bin balance pipe - this enables dust collection in a plastic bag (located in the collection bin hopper) that can be quickly sealed on removal, minimising dust in the open atmosphere and a waste bin level sensor. Depending on the specific zone or environment, the AM dust collector range can be specified with fully ATEX compliant motor, controls and switchgear.

Mark Viner, Guyson International’s Commercial Director explains that “the Euroblast 6SF-AM is just one of a range of seven 'standard' cabinet sizes in which Guyson’s premier quality Euroblast cabinets is supplied, a range that also includes sit-down and variable height cabinet designs, together with choices of blast guns, suction or pressure fed operation and a vast range of options and special features to aid component handling”. Mark continues, “the additive manufacturing sector is a key market for us here at Guyson and we work with many organisations, both in the UK and globally, from equipment manufacturers to end users and rapid prototype organisations. It makes sense that we tailor our product to meet the exacting standards that this new and growing sector demands”

Guyson also displayed a Mediblast 1400, (based on their Formula 1400) a fully 316L stainless steel constructed blast cabinet. This version showcases the type of high-end specialist manual cabinet that Guyson offers for blasting medical and dental implants (whether AM or conventionally manufactured) – where no ferrous contamination can be tolerated. The Guyson Formula blast range offers three cabinet sizes, including a bench-top version, and is ideal for smoothing out striation lines, finishing SLS prototypes or creating the perfect keyed surface for painting on FDM 3D printed components.

Also exhibited was a KS525 ultrasonic cleaning tank, representative of Guyson's ‘Kerry’ branded ultrasonic cleaning ranges, all of which provide fast and effective precision cleaning of prototypes in a fraction of the time required by hand cleaning. In addition, these Kerry ultrasonic baths and tanks can be used for support removal on certain prototypes.

The KS525 ultrasonic cleaning tank is just one of their extensive ultrasonic cleaning tank range, with six standard cleaning tank sizes. These aqueous wash tanks’ capacities range from 21 to 275 litres and all are robustly constructed using AISI 316L polished stainless steel for durability, while Kerry ultrasonic generators ensure powerful parts cleaning and long equipment life. Standard KS ultrasonic tanks operate at 38 kHz (±10%); however, the optional Kerry Guysonic generator with Primewave® controls allows the operator to select switchable dual frequency (36/66 kHz ±10%) and variable power control.

Prospective users of Guyson equipment are encouraged to submit sample components for free feasibility testing to the company’s extensive Component Finishing Centre in Skipton, North Yorkshire.
