Microblasting – Areas of application
Demoulding blasting
Mould cavities are densificated after the surface has been cleaned (2 steps technology) in order to reduce demoulding forces and reduce cycle times. Tribological additives are simultaneously dispersed into the mould surface in order to avoid material adhesion.
Electrode cleaning
Cu and graphite electrodes are uniformed after milling, i.e. loose parts are removed, surface pores opened and burrs removed (even in the case of miniature electrodes) so that the service life is extended, targeted blasting is carried out and surface roughness on the tool is reduced.
Adherend surface preparation
Defined surface topographies ( structures ) are produced for the mechanical anchoring of galvanic layers, PVD, CVD, metal injection and plasma coatings etc. Our range includes manual and automatic microblasting machines.
Structuring
Defined VDI-compliant surface geometries and roughness values for plastic injection moulds are generated. The erosion of mould cavities can sometimes be dispensed with. Surface structures can be applied straight after milling or grinding.
Selective Laser Melting (SLM)
The mould inserts, which are constructed with close-contour cooling using layering processes, should be uniformed and subsequently densificated in at least 2 steps after final forming with iepco microblasting technology. This allows even denser mould surfaces and optimally demouldable mould cavities to be achieved.
Cutting and punching tool construction
Very wide range of applications, particularly with subsequent PVD, CVD or galvanic coating. Tangential rounding of the cut edges in the micro range (µm) optimises the service life of the tool edge. Application likewise in 2 steps: cleaning and edge rounding in the first stage, densification of the tool surface in the second microblasting step.
