Shot Blasting for Engine Blocks & Parts

Precision. Performance. Perfection. At Airo Shot Blast, we deliver cutting-edge shot blasting solutions for engine blocks and automotive parts that redefine durability, cleanliness, and surface integrity. Engine components endure extreme pressure and temperatures—cleanliness and precision surface preparation are vital. That’s where our expertise in engine block shot blasting machine comes in.

Why Shot Blasting is Essential for Engine Parts

The engine block, along with crankshafts, cylinder heads, pistons, and connecting rods, demands surface preparation that ensures optimal performance and long-term resistance to wear and corrosion. Shot blasting serves this exact purpose by:

• Removing casting sand and scale

• Improving surface roughness for better paint/coating adhesion

• Revealing cracks or defects for inspection

• Enhancing fatigue strength through shot peening

Whether for cast iron, aluminum, or steel parts, our blasting machines adapt to every material and design complexity.

Engine Block Cleaning with Precision

Our engine block shot blasting machines offer unparalleled consistency. Dirt, grease, flash, and rust are thoroughly removed from internal and external surfaces. This pre-cleaning is critical before:

• CNC machining

• Painting or powder coating

• Quality inspection

• Final assembly

Airo Shot Blast systems guarantee even coverage and high-speed processing, delivering both efficiency and reliability.

Customized Shot Blasting Solutions for Automotive Components

Different components demand different treatment intensities and abrasives. We supply custom-engineered shot blasting machines for a wide range of engine-related parts:

1. Engine Block & Cylinder Heads

• Cleaning method: Turbine wheel shot blasting

• Media used: Steel shots or grits

• Benefits: Complete removal of burrs, sand, and scale without damaging threads or fine passages

2. Crankshafts & Camshafts

• Cleaning method: Rotational hanger type blasting

• Advantage: Reaches complex geometries; ensures uniform peening for improved fatigue resistance

3. Connecting Rods & Pistons

• Media used: Fine steel grit or stainless steel shots

• Purpose: Create optimal micro-profile for coating, enhance fatigue life

We configure everything — from abrasive type and flow rate to blast pressure — to meet industry-specific standards such as ISO 8501, SAE J442, and automotive OEM requirements.

Machine Types Best Suited for Engine Parts

At Airo Shot Blast, we manufacture and supply the following machines, each purpose-built for automotive engine part processing:

Hanger Type Shot Blasting Machine

Perfect for crankshafts, connecting rods, and camshafts. Parts are suspended on rotating hooks for 360° blast coverage.

• Load capacity: 300–5000 kg

• Dust-free operation with advanced filter units

• Optional PLC automation

Tumble Type Shot Blasting Machine

Ideal for smaller, bulkier parts like pistons or valves.

• Continuous batch processing

• Durable manganese steel lining

• No part-on-part damage due to rubber belt rotation

Rotary Table Shot Blasting Machine

Suitable for heavy engine blocks and heads.

• Single/multiple table designs available

• Adjustable blasting angles for full surface treatment

• Robust steel cabinet with wear plates

Superior Abrasives for Maximum Impact

The choice of abrasive media plays a decisive role. We offer a wide selection compatible with our machines:

• Steel Shot (S330–S660): Best for cast iron engine blocks

• Steel Grit: Removes scale and creates angular profiles

• Stainless Steel Shot: Used for aluminum or rust-sensitive parts

• Cut Wire Shot: Suitable for precision peening of crankshafts

All media are recyclable, eco-friendly, and cost-effective when used with our integrated reclamation systems.

Integrated Dust Collection for Clean Operation

Clean air = clean operation. Each of our shot blasting machines for engine components comes equipped with a high-performance dust extraction system. These systems:

• Collect fine particulates and scale residues

• Ensure operator safety

• Comply with international environmental norms (CE, OSHA)

Our filter cartridges are self-cleaning and designed for 24/7 industrial use.

Shot Blasting vs. Other Cleaning Methods

Method	Surface Finish	Cycle Time	Media Recovery	Eco-Friendly
Shot Blasting	Excellent	Fast	Yes	Yes
Chemical Cleaning	Variable	Slow	No	No
Wire Brushing	Inconsistent	Moderate	No	No
Ultrasonic Cleaning	Good (internal)	Slow	No	Yes

Clearly, shot blasting is unmatched in its effectiveness, cost-efficiency, and sustainability for mass production.
