BLAST APPLICATIONS
Blast cleaning and finishing
At Guyson we offer blast cleaning and finishing solutions for a vast range of
surface treatment applications. We can
help you to select the most appropriate system for your particular needs -
whether a basic manual blast cabinet
or a customised machine, for use by an
operator or automated - and the right blast abrasives to achieve the results you wish.
| The video briefly highlights applications such as carbon removal, metal deburring, plastic deflashing, heat scale and investment removal, glass etching and surface preparation. |

blast applications - or click a shortcut button:
Deburring
- Blast finishing can speedily remove lightly attached burrs from complex machined components and can be more effective than hand or machine deburring in areas with poor accessibility. Non-abrasive deburring media leave even fragile materials untouched. Alternatively, Guyson can combine efficient deburring with controlled surface modification, if required.

Stripping
- Paint, lacquer and other coatings can be stripped off with speed and precision without damage to sensitive substrates and with no hazardous chemical handling or disposal problems. If component irregularities are part of the coating problem, blasting can often strip parts and leave surfaces in an improved condition for re-coating. Our Wheelmaster blast systems are regularly used by bodyshops and garages for refurbishing alloy wheels.
- Guyson blast equipment offers a faster, easier and safer alternative to labour intensive paint stripping methods such as manual scrubbing, sanding, grinding, scraping and wire brushing, chemical cleaning and acid etching.
- Blast equipment from Guyson can help achieve new levels of precision, speed and efficiency in many architectural restoration operations.

Cleaning without dimensional change
- Using dryblast techniques pioneered by Guyson, even complicated shapes and sensitive materials can be efficiently cleaned without substrate erosion or dimensional change. Ideal for the precision cleaning of moulds, dies and tools without damage to delicate surfaces. Large wheel-blast systems are often quoted for the efficient cleaning of dies used in extrusion processes.
- Guyson Pencil Blast equipment is frequently used for cleaning or removing heat scale from small intricate shapes, cavities and mould surfaces. It can also be used for localised peening applications and is often specified in conjunction with a Guyson Formula blast cabinet in aero engine repair and overhaul departments.

Deflashing
- Beadblasting can be used to rapidly and thoroughly deflash resin-moulded or die-cast components. Brittle flash can be cleanly removed from intricate components without altering adjacent surfaces by precise selective impact treatment. Alternatively, the flash can be removed whilst an overall cosmetic finish is produced on adjacent surfaces.
- Guyson's advanced media reclamation systems eliminate the clogging and dust problems which may be created in less advanced deflashing equipment. Guyson systems also address the static and other problems associated with plastics deflashing.

Descaling
- Use bead or grit blasting to quickly remove heat scale, surface discoloration, oxides, rust, weld scale or corrosion. Restore a component's looks and remove surface problems that interfere with painting, plating, coating, drawing and other processes. A Guyson blast descaling system may represent a viable alternative to chemical descaling methods such as caustic or acid processing with none of the inherent safety concerns of using hazardous chemicals.

Rapid prototype finishing
- If the objective of your rapid prototyping work is to get the model as near as possible to the finished article for evaluation, testing, or actual short run work, then Guyson blast equipment delivers the finish you require. Blast finishing can smooth out step lines, create the right cosmetic finish, and provide a keyed surface for painting. With our blast equipment you can achieve that essential finish that makes your products stand out from the crowd.
- Choose Guyson for that critical finish on Selective Laser Sintering (SLS) prototypes: used often on automotive components, resin and the latest stereolithography bluestone resin prototypes. See how Guyson blast equipment for rapid prototype finishing

Surface etching
- Improved surface preparation or 'keying' of component surfaces can be achieved using Guyson blast equipment. Fine media blasting in one of our automated blast systems delivers very real improvements in adhesion for performance critical components such as medical implants when they are etched prior to ceramic or PVD/CVD coating.
- Blasting is also able to achieve an optimum surface profile for improved coating adhesion which leads to subsequent improvements in performance and lifespan of machine cutting tools and drills.
- A light surface etch improves bonding to smooth substrates and is often used in the automotive interior and trim market to aid bonding of veneers, plastic and rubber to superstructures.

Cosmetic finishing
- Increasingly, cosmetic finishes can be the competitive edge that makes your product more attractive to the consumer. Whether you are addressing minor surface imperfections, replacing an inconsistent manual blasting operation or streamlining a high-production process, we can help. Guyson uniquely combines expertise in unusual media that create a distinctive surface finish with automation techniques to impart the look of quality with uniform, consistent results. Appearances count more than ever today. Guyson can demonstrate alternative finishes to help you achieve the look you are after, then recommend an automatic blast system to meet your production requirements.
- Manual blast systems come into their own on larger, heavier or lower volume components. Euroblast® manual cabinets fitted with side loaders prove the ideal solution for stone and tile reconditioners, refurbishment companies and restoration workshops seeking to replace slower and more labour intensive methods. Blast finishing can deliver effective cosmetic finishing, artificial ageing and distressing on stone, brick, glass, wood, fabric, ceramic, plastic and rubber artefacts.

Investment removal
- Removing tough, strongly adhering investment from castings made using the lost wax process calls for greater cutting power, which is achieved using hard angular abrasive blast media in an automated or manual pressure feed system. Typical components which would require a very fine tolerance level on intricate shapes and curves include items such as turbocharger hot end wheels, cylinder heads, aero-engine turbine blades, gold and silver jewellery, and dental plates.

Shot peening
- Guyson shot peener systems utilise the latest in process controls and draw on our pedigree in blast automation, enabling us to build peening systems that can deliver a predictable intensity with consistent, repeatable results, to your specifications. Many Guyson automated Multiblast® machines have been sold for peening turbine rotors and blades to comply with worldwide aerospace standards.

Engraving and etching glass
- Blasting can be used as a fine etching process to produce logos and insignia on glass, pottery, cutlery and medals, in an extremely fast operation – a drinking glass can be etched with a measure insignia in around one second. Also distinctive patterns, textures and frostings can be achieved on flat plate glass and art glass by use of varied media types and pressure settings. Ranges of dedicated machines specifically designed for glass etching include Euroblast GL manual blast cabinets for flat glass decoration.
