Shot Blasting Machines

Shot Blasting Machines Built for Cleaner, Stronger, Paint-Ready Surfaces

Rust, scale, sand and old coatings don't come off with a wire brush, not at production speed anyway. Airo Shot Blast Equipments designs and manufactures industrial shot blasting machines that clean metal parts fast, leave a uniform finish, and keep running shift after shift.

What Is a Shot Blast Machine and Why Do Factories Rely on It?

A shot blasting machine throws small steel abrasives (shot or grit) at a metal surface at very high speed. A spinning blast wheel does the throwing. The impact knocks off rust, mill scale, sand, burrs and old paint, and it leaves a slightly roughened surface that paint, powder coating or galvanizing grips well.

Compared with manual grinding or chemical pickling, it is quicker, more consistent, and far less dependent on operator skill. The same abrasive is also cleaned and reused many times, so running costs stay low.

At a glance card:

• Cleans: rust, scale, sand, paint, weld spatter
• Works on: castings, forgings, fabricated parts, structural steel, springs, pipes
• Result: uniform finish, better coating adhesion
• Bonus: improves fatigue life when used for shot peening

Product Range

Types of Shot Blasting Machines We Manufacture

Every part behaves differently in a blast chamber, so one machine doesn't suit all. Here is how our range breaks down.

1. Hanger Type Shot Blasting Machine. For large or awkward parts such as heavy castings, fabricated frames and gearboxes. The load hangs on a hook and rotates while it's blasted from all sides.
2. Tumblast (Tumble Belt) Machine. For small, tough parts like bolts, forgings, bearing components and small castings that can be tumbled without damage.
3. Table Type Shot Blasting Machine. A rotating table holds medium-sized components and presents every face to the blast stream. Good for batch work.
4. Spinner Hanger Machine. A compact version of the hanger machine with hooks that spin, ideal for mid-weight parts and mixed-batch loading.
5. Wire Mesh Belt Machine. For delicate or thin parts (springs, stampings, aluminum die castings) that need a gentler, continuous flow.
6. Roller Conveyor Machine. For plates, sheets, beams and profiles that pass straight through the chamber, common in steel fabrication.
7. Pipe Blasting Machine. For cleaning the outside (and, with a special setup, the inside) of pipes before coating.
8. Continuous Line and Automated Systems. For high-volume plants that need loading, blasting, cleaning and unloading with almost no handling.
9. Custom Blasting Solutions. Odd shapes, tight floor space, special finishes: we'll design around your part instead of forcing it into a standard machine.

How a Shot Blasting Machine Works, Step by Step

1. Load. Parts go into the chamber by hook, table, belt or conveyor.
2. Throw. The blast wheel accelerates abrasive to high velocity and hits the surface.
3. Clean. Rust, scale and residue break away on impact.
4. Separate. A separator lifts the abrasive out of the mixture, sending clean media back and dust to the collector.
5. Filter and finish. The dust collector removes fine particles so the air is clean and the parts come out dry, clean and ready for coating.

Key Components

We build the parts that wear out fastest with the most care, because that's what decides your maintenance bill.

• Blast wheel and impellers: Made from wear-resistant alloy for longer life and steady throw.
• Control cage and blades: Set to aim the abrasive stream where it's needed, cutting wasted shot.
• Manganese or wear-lined chamber: Protects the body from constant abrasion.
• Bucket elevator and screw conveyor: Move the abrasive quietly and reliably back to the hopper.
• Air-wash separator: Keeps only good-size shot in circulation for a consistent finish.
• Cartridge or bag-type dust collector: Keeps the shop floor and the environment clean.
• PLC panel and safety interlocks: Simple, operator-friendly controls with protection built in.

Applications 

1. Foundries: Removing sand and burnt-on residue from iron and steel castings.
2. Forging units: Cleaning scale after heat treatment.
3. Steel fabrication and structural work: Preparing beams, plates and frames before painting.
4. Automotive and auto components: Cleaning and peening gears, springs, axles and suspension parts.
5. Pipe and tube manufacturing: Surface prep ahead of coating or lining.
6. Railways and heavy engineering: Cleaning wagons, bogies and heavy assemblies.
7. Galvanizing and powder coating shops: A dependable pre-treatment step.
8. Construction equipment and agri machinery: Long-lasting finishes on rough-duty parts.

Benefits

• Faster cycle times: Minutes instead of hours per batch.
• Even finish: The same surface profile on the first part and the thousandth.
• Better paint and coating life: A properly profiled surface bonds far better.
• Lower labor dependency: Less fatigue, less skill variation, safer for workers.
• Recyclable abrasive: Steel shot is used thousands of times.
• No acid waste: No pickling tanks or chemical disposal headaches.

Which Shot Blast Machine Is Right for Your Component?

Machine type	Best for	Typical parts	Loading
Hanger	Large, heavy parts	Castings, frames, housings	Hook / trolley
Tumblast	Small, robust parts	Forgings, bolts, small castings	Bulk load
Table	Medium, flat or round parts	Discs, plates, wheels	Rotating table
Spinner Hanger	Mixed medium loads	Brackets, gears, mid castings	Hooks
Wire Mesh Belt	Delicate parts	Springs, stampings, die castings	Continuous belt
Roller Conveyor	Long or flat sections	Plates, beams, profiles	Conveyor
Pipe Blaster	Pipes and tubes	Steel pipes	Rollers / feed

How to Choose a Shot Blasting Machine: Size, Capacity and Abrasive Type

• Part size and weight: Decides the chamber type and the loading method.
• Batch volume: A few parts a day and a few tonnes a shift need very different machines.
• Material: Cast iron, steel, aluminum and stainless need different abrasives and intensity.
• Finish required: Steel shot gives a smoother, peened surface; steel grit gives a sharper, cleaner profile.
• Floor space and power supply: Tell us your layout limits early so we design around them.
• Dust and pollution norms: Confirm your local requirements for the collector.
• Future growth: Leave headroom if production is likely to rise.
