Surface Preparation for Parts That Cannot Be Tumbled
While tumble blast machines are ideal for bulk hardware, heavy or delicate components suffer edge breakage, thread stripping, and surface denting if tumbled together. The hook type shot blasting machine (Q37 series) suspends components individually or on tree fixtures, delivering complete surface descaling with zero part-on-part contact.
No Collision Damage: Ideal for delicate aluminum housings, thin-walled ductile iron castings, high-precision gear blanks, and complex welded frames.
Thorough Rust and Scale Removal: Strips thermal scale, slag, and rust across intricate geometries, preparing surfaces to ISO 8501-1 SA 2.5 cleanliness before liquid coating or powder painting.
Flexible Batch or Single-Piece Processing: Accommodates individual large workpieces up to several tons, or multiple small parts suspended on multi-tier fixtures.
How Dual-Hanger Rotation Systems Maximize Output
Standard hanging systems eliminate cleaning dead-zones while keeping blast cycles continuous:
Internal Workpiece Rotation & Oscillation: Inside the blast cabinet, the motorized hanger continuously rotates and oscillates, presenting internal cavities, ribs, and deep recesses directly into the multi-angle blast streams.
Dual-Hook Non-Stop Operation (Y-Track System): While one hook is rotating inside the sealed cabinet undergoing blasting, the outside hook is simultaneously being unloaded and reloaded by operators.
Multi-Wheel Blast Coverage: Multiple direct-drive blast heads are strategically positioned on the chamber side walls to cover both upper flanges and lower structural bases in a single cycle.
Core Configurations: Single Hook vs. Dual Hanger Overhead Systems
To match different shop lifting capacities and plant layouts, two primary hook blaster configurations are available:
Single Hook Blast Machine: Compact footprint suited for job shops and intermittent batch cleaning of medium-to-large single components.
Dual-Hanger Y-Track Blast System: High-throughput configuration engineered for continuous foundry casting lines and heavy structural fabrication workshops.
Heavy-Duty Engineering Standards by HQAMUR
High-Wear MN13 Interior Protection: Blast zones directly facing blast wheels are lined with thick rolled MN13 manganese armor, preventing shell wear under aggressive metallic shot impacts.
Precision Seal on Overhead Slot: Multi-layer wear-resistant rubber sealing plates close the overhead conveyor roof slot, preventing abrasive escape while allowing smooth hanger travel.
Automated Pulse-Jet Filtration: Integrated pulse-jet cartridge dust collectors maintain strong cabinet negative pressure and deliver clean emissions below 20 mg/m³.
