Double Hook Shot Blasting Machine: High-Efficiency Surface Treatment for Batch Processing
Introduction
In industries such as automotive, foundry, and heavy machinery manufacturing, components like gears, castings, forgings, and engine blocks require consistent and thorough surface preparation to ensure durability and performance. Double hook shot blasting machines are engineered to automate the cleaning, descaling, and peening of medium-to-large parts in high-volume production environments. By utilizing dual rotating hooks to suspend and rotate workpieces during blasting, these systems optimize throughput, precision, and energy efficiency.
Hook Shot Blasting Machine
37 series hook type sand blast machine/ hook abrasive blaster is mainly used for surface cleaning and strengthening of steel structural parts, castings, aluminum alloy parts and other spare parts. It is widely used in foundry, mechanical and steel industry . This series has following advantages: no pit, double hook without rail exchanging, compact structure,and high productivity.


Features:
1. The equipment is mainly applied in the processing of medium and small size workpieces in large scale. It has the advantage of high efficiency, compact structure.
2. Workpieces can be transported continuously. The working procedure is that, setting the speed, hanging workpieces over the hooks, and removing them after shot cleaning.
3. Each single hook can hang weight from 50 kgs to 2000 kgs with high productivity and stable running.
4. It makes a best effect on complicated workpieces both the surface and inner part, such as cylinder cap of engine and motor casing.
5. It is an ideal choice for auto, tractor, diesel engine, motor and valve industry.
