MicroBlasting Technologies for Automotive Manufacturing
Micro-precision sandblasting is deceptively simple. Unlike traditional sandblasting, this process uses very fine media, small nozzles, and a consistent abrasive feed to deliver a tool with a laser-beam focus and exacting precision. Clean, strip, texture, etch and deburr delicate surfaces without causing dimensional changes to part geometry.
What can be achieved with MicroBlasting?
MicroBlasting is an effective solution in the automotive field for precision deburring of fuel splines, and gears, texturing stator connectors and glass for bond adhesion and.
Delineation
0.007″
Create a consistent surface finish with a 0.007″ delineation between blasted and unblasted regions.
Depth Control
70 nm
Etch channels for microfluidics with precise depth control.
Surface Finish
0.13 – 3.8 micron
Control the Ra and Sdr of your finish within 10%
Conformal Coating Removal
Selectively remove conformal coating from printed circuit boards without damage to the board.
Fuel injectors
Automated system designed to peen the interior of the fuel injector, allowing for higher compression pressures to meet new emission requirements.
Multi-axis Load cells
Joining dissimilar materials, like flex circuitry to aluminum, requires unique surface enhancements. This includes the removal of anodized finishes and the creation of properly developed surfaces.
Connectors
The harsh environments of fuel systems require effective sealing at the connector sites. Proper surface preparation makes the joint more durable.
Brittle vs. Ductile
The coating removal process uses the abrasive qualities of MicroBlasting to carefully erode layers of unwanted material from a base substrate. The process takes advantage of the different physical properties of the two layers. Brittle materials can be removed from soft ductile layers, or soft ductile layers can be removed from brittle layers.

Need a consistent and repeatable surface finish?
What do you include in your surface finish specification? How you define a surface texture makes a difference. Do you define it by the method or the results?

Nozzle Angle
Abrasive particles transfer the most impact energy when the nozzle is positioned at 90° to the target, but abrasive particles ricochet at this direct angle, crowding and slowing the stream. When cleaning or eroding surface material, hold the nozzle at or near a 75° angle to the target.

The AccuFlo® produces a steady flow of abrasive which ensures consistent results. It processes parts faster than most traditional micro-abrasive blasters, and it does so with greater powder efficiency. The AccuFlo is able to handle a wide-range of abrasives and suits most MicroBlasting applications.
