Blasting

There are two ways to throw abrasive at a part. With a centrifugal wheel, or with compressed air through a nozzle. They do the same thing. Not at the same rate, and not for the same parts. The throughput difference A wheel propels the abrasive mechanically. The blades throw it, and the energy comes straight […]

Wheel blast machines differ in how the part moves in front of the wheel. Everything else follows from that: which parts you can process, and how fast. Tumble barrel Parts sit in a rotating barrel. The wheel throws the abrasive, and the parts tumble, exposing every face. For: small, robust parts in bulk. Castings, forgings,

Two families of round metallic abrasive, with different prices and different behaviour. The choice is not obvious, and in shot peening it matters more than in blasting. How they are made Cast shot is produced by atomising molten steel. The droplets solidify into spheres. Cut wire is produced from drawn wire, cut into cylinders with

Environmental requirements no longer come only from the authorities. They come from customers’ specifications, since those customers need certifications of their own. The good news is that in blasting, the environmental choice usually coincides with the economical one. The abrasive that comes back into the circuit The fundamental difference is between abrasive that recirculates and

The foundry is the sector where surface cleaning is hardest, for four reasons that usually show up together. Problem 1: complicated shapes that need complete cleaning A casting has ribs, channels, bores and shadowed areas. The abrasive jet reaches exposed surfaces easily and the rest with difficulty. The requirement is 100% cleaning, not 90%. Sand

In the automotive industry, surface preparation is not a final operation. It is a condition for the product being safe and reliable. The applications, though, differ enormously from each other, and the equipment that suits one is wrong for another. Cleaning castings Foundry parts arrive in the automotive industry carrying moulding sand, burrs and oxides.

Blasting and shot peening look like the same thing. From a subcontracting point of view, they are not. Blasting: a visual result In blasting, the result is assessed mainly visually: the degree of surface cleanliness and the roughness achieved. You agree the grade, the work is done, verification is by comparison. The conversation is simple

For small or medium parts, a blast cabinet is enough. But for large metal structures, heavy industrial components, or large-scale series production, the solution is a blast room — a complete industrial space, specifically sized for such parts — followed, in many production lines, by a dedicated painting booth. Blast rooms Industrial blast rooms generally

Sandblasting car wheels is the most effective way to prepare a wheel for a new finish — whether that’s refurbishing, restoration, or simply stripping old paint before repainting or powder coating. Unlike manual sanding, blasting cleans the entire surface uniformly, including hard-to-reach areas between the spokes. What blasting removes from a wheel The process removes

Many people search online for sandblasting sand, out of habit — but the correct term used in the industry today is blasting media (or blasting abrasive). Quartz sand hasn’t been used as a blasting abrasive for decades (over 40 years), precisely because of the health risks described below — although many people still call it
