Blasting technology

Q: Which blasting processes exist and what are they used for?

Common processes include compressed-air blasting (pressure and siphon), wet/slurry blasting, dry ice and soda blasting as well as turbine blasting. Applications include rust removal, paint stripping, cleaning, roughening/satin finishing, surface peening and pre-treatment before coatings.

Q: How do I choose the right abrasive, nozzle and pressure?

Select abrasive by base material, desired roughness (Rz/Ra), cutting performance and recyclability: e.g., white aluminum oxide/coal slag for aggressive removal, glass beads for fine finishes, steel shot/grit for reusable media, plastic for gentle cleaning. Size the nozzle by orifice and Venturi geometry, and set pressure and air volume to suit the part, media and compressor.

Q: Which factors influence removal rate, surface appearance and cost-effectiveness?

Influencing factors include media type/grit size/hardness, nozzle wear and orifice, blast pressure, standoff distance and impact angle, cycle time as well as extraction/filtration and moisture content. Proper recycling/separation, dry compressed air, tight hose connections and suitable PPE increase process safety, consistency and efficiency.

Discover high-quality abrasives such as aluminum oxide, glass beads, steel grit and plastic media as well as nozzles, nozzle holders, blast hoses, blast pots and blast cabinets. We also offer extraction and filter technology, personal protective equipment (PPE) and a wide range of accessories. Whether pressure blasting, siphon blasting, wet and slurry blasting or dry ice and soda blasting – we tailor your blasting solution precisely to the part, surface requirements and cycle time.

Use & benefits

Blasting technology ensures consistent surface preparation, optimal adhesion for coatings and defined roughness profiles. For cleaning, decoating or matting – properly designed blasting systems increase process stability, reduce rework, lower media and energy costs and deliver reproducible surface results in both workshop and series production.

Technology & settings

Abrasive selection: by base material and target roughness – e.g., white aluminum oxide or slag for aggressive removal, glass beads for a fine finish, steel grit/shot for durable, recyclable processes, plastic for delicate surfaces.
Nozzles: choose by orifice (6–12 mm) and Venturi geometry for pattern and pressure efficiency.
Blast pressure: typically 2–8 bar; lower pressures for fine or temperature-sensitive substrates.
Air demand & compressor: match output to nozzle size and takt time; ensure dry compressed air.
Extraction & filters: choose to suit dust class; size filter area, separation efficiency and air volume correctly.

Accessories & integration

The range includes blast pots, metering and mixing valves, moisture traps, air dryers, protective and blast hoses, nozzle holders, blast cabinets, viewing windows, separators, filter and extraction systems, blasting hoods and PPE as well as pressure gauges, gauges, cleaning and test media. We verify the compatibility of nozzle, hose, air demand and abrasive and integrate the system into your workshop or line.

Frequently asked questions about blasting technology

Which blasting processes exist and what are they used for?

Common processes include compressed-air blasting (pressure and siphon), wet or slurry blasting, dry ice and soda blasting as well as turbine blasting. Applications include rust removal, paint stripping, cleaning, roughening/satin finishing, surface peening and pre-treatment prior to coatings.

How do I choose the right abrasive, nozzle and pressure?

Choose the abrasive based on material, target roughness (Rz/Ra), removal rate and recyclability: e.g., white aluminum oxide/slag for heavy cutting, glass beads for fine finishes, steel shot/grit for reusable media, plastic for gentle cleaning. Size the nozzle by orifice and Venturi geometry, and select pressure and air volume to match the part, media and compressor.

Which factors affect removal rate, surface appearance and cost-effectiveness?

Influences include media type/grit/hardness, nozzle wear and orifice, blast pressure, standoff distance and impact angle, cycle time as well as extraction/filtration and moisture content.
