Surface cleaning
Shot Cleaning

Surfaces which are blasted with round or angular abrasives are cleaned and prepared for downstream coating processes. Descaling and deburring of cast or forged components, descaling of and rust removal from steel profiles or the removal of old paint and other coatings are just a few typical examples. Especially when angular abrasives are chosen, shot cleaning alters specific properties of the surfaces. It can be used to roughen brake pad mounts, for instance, create a positive fit with brake pads or roughen surfaces in prepara- tion for a subsequently applied metallic coating, e.g. prior to galvanising.

Roughening

Roughening is used to create positive fits, e.g. for brake pad mountings, and to improve adhesion. The slight roughening of surfaces to improve adhesion for subsequent coatings is known as sweeping. Matting roughens, for example, rolling mill rolls in a defined manner. Metallic workpieces also undergo roughening as preparation for chrome or nickel coatings.


Deburring

The purpose of deburring is to remove casting burrs and to eliminate or round off cut edges. Typical applications are the deburring of cast parts made of steel or non-ferrous metal as well as machined workpieces such as turned and milled, laser-cut, plasma-cut and flame cut parts.


Rust removal

Rust removal is used to recondition or repair surfaces for a subsequent new coating.


Decoating

Decoating is often also called cleaning and is a very important and multifaceted process. Typical decoating applications are the removal of old paint on existing components and structures, such as buildings and bridges, for the purpose of preparation and repair and subsequent recoating, and for inspection and revision. Oil and grease residues can be removed, e.g. from vehicle parts, and moulds for metal die-casting and injection moulding as well as for glass can be cleaned. Welding slag and other welding residues can also be removed.


Descaling

Descaling is used to remove scale that occurs after heat treatment, forging, pressing or rolling. Examples of blasting products are any hot rolled products such as sheet, wire and bar steel as well as forged products.


Smoothing, Polishing

This blasting application is used to remove marks caused by the machining of workpieces. Matt functional surfaces of tools can also be polished.

Suitable abrasives:


Matting is the process of optically refining surfaces by using fine, angular blasting media. It is a special form of rough blasting, whereby a much finer blasting medium is used. Matt-blasting gives surfaces a homogeneous, matt finish.


Fettling

Fettling or casting fettling is a special application used in the foundry industry. It involves the removal of molding sand and casting residues from workpieces made of grey cast iron, cast steel as well as aluminum cast in sand.


Cleaning

During blast cleaning the blasting material is freed from adhering foreign layers such as scale, rust, paint, etc. It is the generic term for the blasting processes described on this page such as derusting, decoating, descaling or cleaning.


Structure

Structure blasting generates defined surface roughness. In addition to the processing of precision and injection molding tools, this process is also used in the jewelry industry to achieve a special surface finish.


Sweeping

Sweeping is used to roughen blasting material and make surfaces more adherent for a subsequent coating, such as paint.
