Demonstrating an Automatic Conveyor Sandblasting Machine on Your Own Parts
For an automatic conveyor sandblaster, the decisive demonstration is a trial run on the buyer's actual metal workpieces, checking finish, throughput, and fit within the stated chamber and conveyor settings.
Before comparing suppliers of an automatic conveyor sandblasting machine, decide that no demonstration counts unless it runs the buyer's own metal workpieces through the line. A machine that looks convincing on sample parts may behave differently on the geometry, coating, or batch mix the buyer actually handles.
Build the demonstration around practical checks. Do the buyer's parts fit the working chamber, catalogued at 1,400 × 1,100 × 1,000 mm, with clearance for the conveyor path? With 12 blasting guns, how is coverage arranged across the part width, and can the buyer see the finish at each conveyor speed within the 0–5 m/min range? Ask for a trial at the low and high ends of that range and compare surface results and cycle time. In the RFQ, request that the trial use the buyer's material and that acceptance criteria for finish and consistency be agreed in writing before the test.
Before requesting a quote, confirm with the supplier whether a demonstration on the buyer's workpieces is possible, what sample quantity and part sizes are needed, how results will be recorded, and which catalog values are reference figures rather than guarantees for the supplied model.
