Blasted workpiece

Cast iron parts with dirt haze often lead to complaints

During the blasting process, blasting media contaminated with oil or grease transports and distributes the contamination. All surfaces coming into contact with the abrasives are wetted with the oils and greases within a short time. The result is uncontrolled carry-over.
Surfaces to which a corrosion protection coating is to be applied must therefore be purified with considerable effort by washing and drying, and degreased. This results in unnecessary costs and requires time and natural resources.
In the casting of die-cast parts, the blasting process is frequently used to produce a surface finish.

By wetting with an oil film, dust particles from abraded metal and contamination can adhere to the surfaces of the cast parts. This contamination film causes inhomogeneous darkening of the cast parts. This discolouration can vary greatly. Thus, for example, shot-blasted parts from Monday’s production can differ from those of Wednesday’s production. In the automotive industry, for example, this is frequently unacceptable and leads to complaints and re-working.

With PantaTec, good blasting results can be continuously achieved.
