Machine type for your parts
Tumble machines take batches of small robust parts. Hook and hanging-chain machines take fragile or awkward parts. Roller conveyors take plate and profiles.

The running cost of a shot blaster is in its wear parts and abrasive, and a quote that is low on price is often low on liner and blade material.

01
Tumble machines take batches of small robust parts. Hook and hanging-chain machines take fragile or awkward parts. Roller conveyors take plate and profiles.
Ask the material of cabinet liners and wheel blades, and the expected hours before replacement. Those parts wear from the first hour.
Wheel count and motor size set coverage and speed. Ask how many and where they are placed on your part.
Ask the filter type, airflow and whether it is in the price. Aluminium dust raises an explosion risk, so ask how that is handled.
02
Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

| Require this | A pass looks like |
|---|---|
| Blast your parts at the planned speed and inspect them. | Cleanliness and profile meet the grade in the contract, checked by your coating supplier or inspector. |
| Run the dust collector through the test. | No visible dust leaks from seals, doors or the stack. |
| Open doors and service hatches while running. | Wheels stop before the opening allows access. |

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.

Every machine we source in this area is on the Metal & CNC page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
