Industrial finishing equipment manufacturer Guyson International reports that it has recently installed a second Formula 1600 blast cabinet for the surface finishing of rapid prototypes at Renishaw PLC, one of the world’s leading Additive Manufacturing (AM) technology providers based in Gloucestershire, UK.
Both Guyson Formula blast finishing cabinets have been installed to enable Renishaw’s in-house R&D department to explore the potential that blast finishing has in order to create desirable surface textures on their additively manufactured metallic prototypes.
The Guyson Formula blast cabinet range comprises four strong and durable steel cabinets that are ideal for light industrial applications or when blasting is required on an intermittent basis. All use the industrial quality model 400 blast gun, which can be tailored to suit air supplies of between 8 and 16 cubic feet per minute when blasting at 80 PSI.
The F1600 has a full height side opening door on the right hand side of the cabinet and has internal cabinet dimensions of 1070 x 760 x 770 mm; large enough to accommodate most prototypes.
Blasting is controlled by foot pedal, leaving both hands free to manipulate part under the blast nozzle if it is held in the gun holder, or with one hand to hold the gun and one hand to rotate the part if using the gun free hand.
The F21 dust collector comes standard with this cabinet but if more regular or continuous blasting is required, then the optional F41 dust collector with a double size filtration area can be specified. All Formula blast cabinets have sealed gauntlet gloves, a protected toughened glass viewing window and a quick release media changeover facility; useful if a variety of different blast media is used.
Blast finishing is used to remove surface step lines created during the prototype building process as well as create a bright ‘as new’ surface finish for sintered products.
