MasterFinish 75

Standard injector microblasting machine for the defined optimizing and uniforming of mould surfaces

 

Every operation on metallic surface leaves residual substance like so-called “white layer” after wire or cavity-sinking EDM operation, or residue after grinding. These inadequate surfaces often lead to problem at ejecting of plastic parts or to contamination by deposit. Your moulds can be prepared adequately for high productivity and long running-time by surface treatment using XINTECH micro-blasting unit. In this multiple-stage process, exactly defined blasting agents are used of which composition and the grain diameter are specified for each application. The quality of produced parts depend mostly on the condition of the mould, especially in plastic processing field.

EDM-operated surfaces: The “white layer” which arises after wire or cavity-sinking EDM operation (melting zone in case of hardened metal) can be removed by using XINTECH micro-blasting technique. An optimizing of the surface roughness takes place at the same time. XINTECH MasterFinish is able to carry out blasting operation with pressure setting < 0,5 bar even without blasting-media accelerator. Grinded surfaces: Grinding wheel of flat or cylindrical grinding machine influence the operated surfaces negatively, for example : groove, overheating or carbide contamination. Such loose particles can be removed completely by XINTECH micro-blasting process. After this operation, the cleaned surfaces can be smoothed to the desired friction coefficient.
