Product Description

Product Description

ATHI Q32 Series Tumble Belt Shot Blasting Machine(Rubber / Steel Crawler Type)

The ATHI Q32 Series is a compact, batch-type shot blasting machine designed for the surface cleaning, rust removal, and strengthening of small to medium-sized workpieces. It uses a high-speed blasting turbine combined with a tumbling belt to ensure 360° coverage without dead angles.

How It Works: Workpieces are loaded into the blasting chamber. As the rubber or steel crawler moves, it gently tumbles the parts. The high-speed abrasive stream cleans the surfaces evenly. Finally, the crawler reverses to automatically unload the cleaned parts.

Our Core Advantages

Unlike standard tumble blasters, ATHI provides Application-Specific Solutions to protect your workpieces while maximizing efficiency.

1. Dual-Track Options for Zero Damage:

· Rubber Belt (Standard): Designed for non-ferrous metals and delicate parts. The high-wear-resistant rubber absorbs impact, ensuring "Zero Collision Damage" to your products.

· Mn13 Steel Belt (Heavy Duty): Designed for heavy castings and high-temperature parts (>100°C). Made of Mn13 High Manganese Steel, offering superior load capacity and impact resistance.

3. Automated & Labor Saving:
· Supports Automatic Hydraulic Loading & Unloading systems (optional). One operator can manage 2-3 machines simultaneously, reducing labor costs significantly.

2. Built to Last (Longer Lifespan):
· The blast chamber is lined with Mn13 protective plates (not cheap rubber or standard steel), extending the machine's service life by 3-5 times compared to competitors.

· Blade Lifespan:Taiwan made special material blades, which has 1000-1600 hours lifetime.

4. Eco-Friendly Operation:

· Equipped with a high-efficiency dust collector, keeping dust emissions ≤15 mg/m³ and noise ≤85 dB, ensuring a safe working environment.

Application Industries

· Die Casting & Precision Casting: Removing sand and oxide scale without damaging part geometry.

· Heat Treatment: Cleaning oxide skin after heat treatment.

· Automotive Parts: Gears, springs, shafts, and fasteners.

· Stainless Steel & Aluminum: Surface texturing and aesthetic finishing.

Installation & Service

· 35 Years' Experience: Expertise in shot blasting manufacturing.

· Global Trust: Successfully delivered 2,000+ projects in over 80 countries.

· Global Standards: ISO9001, ISO14001, CE, and TUV certified.

· Worry-Free Service: Providing one-stop solutions, including overseas installation and lifetime technical support.
