Comco manufactures micro-abrasive blasting equipment. MicroBlasting is the process of accurately mixing air and abrasive to texture, deburr, clean or erode a surface. A few industry applications include:

  • deburring valves, poppets, splines and fuel injectors
  • deburring PEEK implants, stents and bone screws
  • cleaning holes in turbine blades
  • texturing load cells for better bond adhesion
  • removing MgO to expose contacts for bonding on heat-sensing harnesses
  • texturing orthopaedic implants
  • milling channels to control fluid transfer and heat buildup on ring bearings
  • removing metalization on ceramic components
  • texturing injection mold cavities to hide splay lines, flow lines, knit lines, blush marks and other molding flaws
  • applying serial numbers to lensses without micro-cracks on ring laser gyros
  • removing oxides and HAZ from laser cut stents
  • removing PTFE coatings on guidewires
  • cutting composites
  • machining vias in glass and silicon
  • removing graphite on mechanical heart valves

  • ProCenter Plus
    The ProCenter Plus™ combines a compact dust collector and chair-height work chamber in one freestanding unit. It creates a clean, comfortable work environment with great visibility and is the perfect partner to any of our blasters....

  • Everything but the Blaster

    Comco’s innovative ProCenter Plus delivers a space-saving WorkStation, dust collector and air dryer in one freestanding unit. It is the “everything else” you need to construct the appropriate blasting environment.

    Designed specifically for MicroBlasting, Comco’s ProCenter Plus combines all necessary accessories into one self-contained system on wheels that is convenient for any workplace. It rolls easily through a standard doorway and has a footprint of only 30″ x 34″.

    A System Anyone Can Use

    The ProCenter Plus provides an ergonomically-designed MicroBlasting cabinet for any operator. It features chair-height access and wide hand holes that have comfortable, flat, cushioned bases. This space and comfort allow the operator a greater range of motion than conventional irises provide. Operators do not need heavy, awkward gloves if this all-in-one unit is partnered with the focused abrasive delivery of Comco’s AccuFlo® blaster. The large viewing area is well lit, and an optional magnifier can be installed to assist with the processing of small parts.

    Powerful Enough for Production

    Every facet of the design—the shape,materials and components—takes advantage of modern manufacturing techniques and capabilities to create a rugged and efficient system. The curved floor, air jets and HEPA filtration all work together to provide a clean work environment during multi-shift blasting without the need for frequent maintenance.

    Quiet Enough for a Museum

    The ProCenter Plus operates at a sound level of just 68 dBA. Through integration of the workstation and the dust collector, Comco’s engineers improved both, incorporated a silencer and opted for a smaller fan. The result is a compact system that not only does a better job of collecting spent abrasive, it does so more quietly.

    To reduce noise without sacrificing efficiency, our engineers focused on:

    • Optimizing our downdraft technology. By allowing the spent abrasive to naturally fall through the floor and into the collection hopper, less airflow is required.
    • Reducing resistance in the path of the airflow by eliminating places within the system that cause a drop in pressure. The result is a compact system featuring a smaller fan that still achieves high volumes of air flow.
    • Minimizing the velocity of the air as it leaves the system and keeping the airflow away from the operator. The ProCenter Plus’ wide exhaust port sits on the back of the system and points toward the floor.

    When Only HEPA Filtration Will Do

    A powerful dust collector with advanced downdraft technology, the ProCenter Plus comes equipped with an easy-to-replace HEPA filter. Spent abrasive is swiftly evacuated from the large, well-lit chamber, keeping the work area clean. HEPA air filtration means 99.97% of all particles greater than 0.3 micron in size are removed.

    The air coming out of the ProCenter Plus is cleaner than what goes in, because we believe in leaving a place better than we found it. Our HEPA equipped ProCenter Plus efficiently cleans the air before it’s discharged back into the work area.

    ESD Control for Static Sensitive Applications

    Available on our ProCenter Plus, the ESD control option is designed for static-sensitive applications, such as conformal coating removal, PCB failure analysis, set-top board refurbishments and delicate medical electronics blasting.

    The ESD Control ProCenter Plus floods the blast chamber with ionized air to dissipate any charge developing through the blasting process.

    Maintenance in Minutes

    Filter cleaning is a “knock.” The filter mallets allow the operator to quickly knock off spent abrasive that accumulates on the underside of the HEPA filter. Regular use of the filter mallets maintains airflow in the work chamber.

    Emptying spent powder from the hopper isn’t the usual mess found with most dust collectors. When cleaning is necessary, removal of spent abrasive is quick and easy with a half-turn of a butterfly valve at the bottom of the hopper.

    The HEPA filter does not need to be replaced often. When it does, simply lift off the cover to expose and swap the filter. No tools are necessary.

  • AccuFlo micro-abrasive blaster
    Our newest MicroBlaster, the AccuFlo®, is our most precise, most flexible and most efficient unit available. Due to our patented Simoom® technology, the AccuFlo easily transitions from use in manual applications to fully automated production environments....

  • Abrasive blasting naturally creates harsh environments.  Erosion increases as the size of the abrasive decreases.  Effectively mixing abrasive with high pressure air and keeping the machine from wearing itself out quickly is a significant engineering challenge.  The AccuFlo® was designed around the following principles.

    KEEP IT SIMPLE

    Our engineers focused on avoiding turbulence at all costs, especially when introducing abrasive into the air stream. Bends and complex shapes focus the abrasive force, which causes rapid wear and tear within the system.

    KEEP IT SLOW

    We believe that particle acceleration should only happen at the nozzle.  Any change in the diameter of the hose or passageway through the machine causes a change in abrasive particle velocity.  Particles traveling at higher velocities wear out the inside of the machine faster.  Changes in diameter of the internal passageways also cause more friction within the blaster.  Any increase in friction reduces the amount of pressure available at the nozzle for particle acceleration.

    MAKE IT ACCESSIBLE

    Machine wear is inevitable in an abrasive environment.  Eventually any component that comes in contact with the abrasive media requires replacement.  The AccuFlo was designed so that essential components exposed to abrasive are accessible and do not require an engineering PhD to replace.  The modulator can be replaced by removing two screws that attach the cover.  The mixing chamber is accessible from the outside of the unit with an adjustable wrench.  Cycle and hour counters help set routine maintenance cycles for those wear parts.

    Featuring Simoom® Technology

    During the early stages of the AccuFlo’s development, we prioritized creating a media mixing technology that was superior to the modulated feed used in our older MicroBlasters. We found that while the modulator itself was a great way to fluidize very fine abrasives, more could be done to intensify the pulsing mechanics of the system to create a more streamlined flow path and reduce turbulence. Simoon Technology is the result of several years of this research and development.

    The PowderGate® Valve

    Originally released as part of our PowerFlo and DirectFlo line, the PowderGate Valve replaced the traditional pinch-valve which simply crushes a soft abrasive hose.  The PowderGate Valve proved to be tremendously wear-resistant and functional in harsh environments. So, we redesigned it to work in our AccuFlo blaster, too.  This scaled-down version fits neatly in the abrasive mixing chamber on the tank, features a straighter flow path, and sits in an easily-accessible spot on the side of the system.  Comco’s PowderGate Valves last hundreds of thousands of cycles in a production environment without maintenance.
