Applications/Micro Abrasive Blasting/Precision Machining Applications

MICROBLASTING APPLICATIONS FOR PRECISION MACHINING

 

Micro-abrasive blasting is ideally suited to precision machining applications.

Deburring Precision machined parts – Burrs left by the machining process may need to be removed. Angled nozzles are often used to deburr openings on complex components such as waveguides and manifolds.

Removing EDM recast and discoloration – EDM processing leaves a residue of graphite compounds that can effectively be removed by micro-abrasive blasting.

Finishing and texturing injection mold cavities – Whether cut by laser, EDM or another method, the surface of a mold cavity may require finishing to prevent plastics from sticking.  Micro-abrasive blasting is an effective process for removing EDM without damaging the intricate geometries of molds.

 Cleaning runner nozzles – Like molds, the nozzles are subject to similar residue build-up.  Manual cleaning must be done with great care since they are easily susceptible to damage.  Micro-abrasive blasting provides an effective method for cleaning off the residue with pinpoint accuracy, increasing the lifespan of expensive nozzles.

Custom Flex Circuit Abrader

We had an unusual request for blasting the back of flex circuits to improve the laser solderability of the parts. The backing was too reflective and meant that the laser welds were not always consistent. A custom machine was built to create a uniform area over the back of the area that is soldered. This means that the area would not reflect the laser and improve the efficiency of the weld.
