Shot Blasting and Surface Cleaning Process

Shot blasting is a controlled surface process, not a universal cosmetic cure. Huabo uses listed flat-belt and tracked equipment for compatible die cast components. The route is selected after considering geometry, part-to-part contact, machined surfaces and what will happen next, such as painting, powder coating or direct shipment.

Process sequence

1. Review incoming condition: confirm oil, heavy flash, deep dents or corrosion that blasting alone should not be expected to correct.
2. Protect critical areas: identify machined sealing faces, threads, grounding pads, bearing seats and fine cosmetic details.
3. Select loading method: choose flat-belt orientation or tracked cleaning according to contact and coverage risk.
4. Approve a trial: compare texture, coverage and dimensional/appearance impact with the requirement.
5. Clean and inspect: remove retained media and check for collision marks, missed areas or exposed defects.
6. Transfer to finish/packing: prevent the cleaned surface from being recontaminated.

Acceptance should describe the intended surface

Common sourcing mistakes

Requesting 鈥渟and blast finish鈥?without a visual standard allows different media and textures to be treated as equivalent. Sending a machined component without marking sealing faces can lead to unwanted surface change. Choosing tracked cleaning only for price can create collision marks on thin or visible parts. These risks are reduced during drawing and sample review.

RFQ information

Send the drawing, alloy, current/raw surface, desired appearance, protected zones, batch size and next coating process. Huabo can then propose the equipment route and identify where a trial sample is necessary.
