Grit Blasting for Chennai Plants

Plants around Sriperumbudur, Oragadam, Ambattur, Thiruvallur and Gummidipoondi make, machine and fabricate castings, welded frames and machine bases. Grit blasting is the preparation that suits these parts.

The process uses steel abrasive to remove scale, rust and foundry sand from the part, and leaves an even, profiled surface that primer accepts uniformly. It also reveals casting defects before they are painted over.

For a Chennai plant, batches of parts may be dispatched to our Bengaluru facilities, about 350 km away, and returned blasted and primed. Where the work is a structure that cannot be moved, our team blasts it at your site to the same standard.

Grit Blasting Projects from Chennai

We begin with photographs or a drawing, and the parts follow. On arrival they are inspected for oil and grease, and machined faces, bores and threads are masked. Blasting is carried out to Sa 2 or Sa 2½ as specified, after which dust and abrasive are blown out of pockets and cores.

Primer is applied promptly in the same unit, and parts can be finish painted in our booths. Castings that must be stress relieved before machining can pass through our furnaces first, so that furnace, blasting and paint remain under one roof.

Frequently Asked Questions

Is grit blasting available at our plant near Chennai?
Yes. We confirm the arrangement after reviewing the parts, the quantity and the schedule.
Is it worthwhile to send parts about 350 km?
Repeat batches of castings or frames, where every part needs the same finish, benefit most from our Bengaluru facilities. A single structure is often better blasted at your site. If you share the details of the parts, we will advise which arrangement fits.
Our castings are going for zinc or aluminium spray. Which abrasive is used?
Metal spray requires a clean, sharply profiled surface, and the abrasive is chosen to achieve this. Please indicate which coating follows, and we will select the abrasive and the grade accordingly.
What should be provided with an enquiry?
We would appreciate drawings or photographs, the material, approximate size and weight, the quantity, the blast grade required and the coating that follows. Please also mention whether the parts must be stress relieved first.
