“…Also, powder blasting is considered the only feasible technique to create thousands of holes at once with a low cost, high speed, and high accuracy for the production of Zeus panels [8]. Other technologies, such as ultrasonic machining, photoforming of photosensitive glass, and laser machining, are not suitable for those applications because of either the technological requirements or cost limitations.…”

Sandblasting, a conventional technique which is used for paint or scale removing, deburring, and glass decorating, has recently been developed into a powder blasting technique for brittle materials capable of producing micro-structures larger than 100 lm. This article describes an investigation of the effects of the impact angle of particles, the scanning times, and the standoff distance on the surface roughness, the weight-loss rate of samples with no mask, and the wall profile and overetching of samples with different mask patterns in powder blasting of soda-lime glass. The parameters are the various impact angles between 50 and 90°, the scanning times of a nozzle up to 40, and the standoff distances between 70 and 100 mm. The widths of the mask pattern are 0.2 mm, 0.5 mm, and 1 mm. The powder used is Al2O3 sharp particles, WA#600. The mass flow rate of powder during the erosion test is constant at 175 g/min and the blasting pressure of the powder is 0.2 Mpa. After a series of necessary experiments are performed, the results are investigated and analysed. As a result, a fundamental basis is established that can be applied to powder blasting to produce micro-mechanical parts of glass.

“…This socalled "powder blasting" process, developed for, e.g., flat panel displays [20] and microcounter-flow heat exchangers [21], was recently exploited to fabricate fluidic structures for capillary electrophoresis [22]. Glass removal rates with this process, which consists in directing a jet of powder particles to a brittle material in order to erode that material locally, are typically between a few mm/min and 1 mm/min.…”

The applicability of glass chips with powder-blasted microchannels for electrophoretic separations was examined, and the performance was compared to microchannels etched with hydrogen fluoride (HF), using bicarbonate buffer and rhodamine B and fluorescein as model compounds. The measured electroosmotic mobilities in all chips were comparable, with values of ca. 7 x 10(-4) cm(2) V(-1)s(-1). The effect of electrical field strength and detection length on the separation efficiency was monitored. It was found that the main source of dispersion is of the Taylor-Aris type, which was discussed in relation to channel roughness differences. Although in powder-blasted channels with a separation length of 8.20 cm, 7-9 times lower plate numbers were obtained than in a HF-etched channel with similar dimensions, successful separation of five fluorescein isothiocyanate (FITC)-labeled amino acids was obtained on a powder-blasted chip within 80 s. Efficiencies of up to 360 000 plates/m were demonstrated on this chip, when a higher buffer concentration was used at a field strength of 664 V/cm. It can be concluded that powder-blasted microchannel chips, although they have a lower separation efficiency compared to HF-etched chips, perform well enough for many applications. Powder blasting can therefore be considered a low-cost and efficient alternative to HF etching, in particular because of the possibility to fabricate access holes through the glass with the same process.

“…If the length l c and the depth d c of the lateral crack can be obtained, the erosion rate Q, which is defined by the ratio of the removed workpiece weight to the unit weight of the abrasives, can be calculated from the following equation [4]. Here, it is assumed that each abrasive removes the workpiece in proportion to the depth and surface area of the lateral crack.…”

The main objective of this research is to develop a mechanical etching technique to produce micro mould dies having micro pockets of hundreds of µm. A powder blasting technique is applied to stainless steel plates based on predefined process conditions. This paper describes the performance of a powder blasting technique and the effect of the number of nozzle scanning times and the stand-off distance of the nozzle on the depth and width of pockets. Required blasting and measurement steps are performed to extract the relationships between given process parameters and machined results. Experimental results show that increasing the number of nozzle scanning times and decreasing the stand-off distance of the nozzle increase the depth and width of machined pockets. Increase of the width of the pockets results from mask film wear. The results of this research can be a fundamental basis to produce more accurate and smaller micro pockets using the powder blasting process.
