Micro-abrasive blasting works by uniformly mixing air with an abrasive media, then propelling the mixture out of a small nozzle tip at high velocity. The process is sometimes referred to as precision sandblasting or pencil blasting because the handpiece is held like a pencil and the end of the nozzle resembles the tip. The consistent flow provided by a MicroBlaster® model, the micron sized abrasive particles, and the small opening of the nozzle deliver a stream of abrasive that is very focused, making it an ideal process for a variety of precision applications.
Micro-abrasive blasting is cost effective and environmentally friendly.
Micro-abrasive blasting equipment
Micro-Abrasive BlastersThe micro-abrasive blaster is the heart of the system. It generates the abrasive stream by mixing compressed dry air with the abrasive media. Comco offers three lines of micro-abrasive blasters to meet a range of applications.
MicroBlaster®: Tough enough to perform in high volume production environments, this compact blaster is also an affordable choice for shops requiring micro-abrasive blasting only a few days a week. It is ideally suited for both manual and semi-automated applications.
AccuFlo™: This new blaster provides more flexibility and enhanced powder flow control for a wider range of applications. It is ideally suited for both manual and semi-automated applications.
The increased power and powder capacity this blaster offers enables the use
of larger nozzles or multiple nozzles. It is ideally suited for both manual
and semi-automated applications.
has integrated the precision of micro-abrasive blasting with an advanced
machining platform for superior control quality and repeatability.
In addition to the micro-abrasive blasting unit, the following components are required for efficient blasting:
Workstations: When the abrasive stream is propelled from the nozzle, there must be a means of containing the spent abrasive. The workstation not only captures the abrasive particles but also provides the operator with a high visibility work area. A Magnifier is also available to aid visibility when blasting small parts.
Dust Collectors : The dust collector is specifically designed to handle micron-sized particles, maintaining good operator visibility and a clean workstation.
Spares And Repairs : Because of the abrasive nature of microblasting, regular maintenance and repairs are necessary on the most common wear items. We offer a full backup and support service and hold stock of most common nozzles and normal wear parts and can offer repair advice, assistance and refurbishment for old or non-functioning blasters.
Custom Abrasive Blast Systems
Over the last couple of years, Epak Electronics Ltd have supplied numerous custom automated systems based around specific applications customer have had for micro abrasive blasting. In conjunction with customer needs, we have developed a sophisticated multi-nozzle surface abrader in 150 and 170mm belt widths, a motorized rotary blast nozzle and several other customer specific applications. If you have an automation requirement, please contact us to discuss your needs.
The micro-abrasive blasting system includes the following components: micro-abrasive blaster, workstation, air dryer and dust collector. Accessories are available to make the application easier and these include many sizes and types of nozzles, a magnifier, special ring nozzle for wire stripping and options for the blasters including a touchstart handpiece, a blast timer, constant air bleed and splitters for multi-nozzle blasting.
ApplicationsThe versatility of micro-abrasive blasting is one of its greatest assets. The process is used in a variety of industries from the manufacture of medical implants to the restoration of prehistoric fossils.
Find out how best to process your parts in our Applications Lab. Whether your application is among the many tried and tested or something new, we offer parts testing to find the best method in micro-abrasive blasting. We would request you send us sample parts that are indicative of those used in production rather than parts that are un-useable or scrap as it gives you a better idea of how the process could work as one of your process improvement steps.
Most applications are performed manually, but advancements have led to a
rise in automated operations.
