Q38、Q48 Series Catenary Type Shot Blasting Machine

1.What are Q38 and Q48 series hanging chain type shot blasting cleaning machines?

The Q38、Q48 Series Catenary Type Shot Blasting Machine are among the core products of Shandong Kaitai. As high-efficiency equipment for batch surface treatment of workpieces, they automatically convey workpieces into the blasting chamber via an overhead conveying system. 

High-speed shot blasting impacts are adopted to remove scale, rust and welding slag, so as to improve the surface quality and fatigue resistance of workpieces. The core difference between the two models lies in their operation modes. The Q38 series features a continuous through-type design. Driven by the overhead chain, workpieces pass through the blasting chamber at a constant speed and are cleaned during transportation, delivering extremely high production efficiency. 

It is especially suitable for mass production of small and medium-sized workpieces with a single specification. In contrast, the Q48 series adopts a stepping through-type operation. After entering the blasting chamber, workpieces stop at fixed positions and rotate on their own axes. 

They are thoroughly cleaned from all directions before being conveyed out. Although this stepping mode results in a slightly longer processing time per hook, it achieves more thorough and uniform cleaning effects, making it particularly applicable to complex-shaped workpieces such as engine cylinder blocks and motor housings. Both models have the advantages of compact structure and easy integration into automated production lines, serving as ideal options for industries including automobile, tractor and valve manufacturing.

2. Main Operation Mode

The following are the core parameters of the three mainstream models in the Kaitai series. You can make a preliminary model selection according to the size and weight of the workpiece:

3. Main Technical Parameters

There are significant differences in parameters among different models of  Q38、Q48 Series Catenary Type Shot Blasting Machin. The key parameters of several common Kaitai models are listed below:

4. Main Application Fields

This equipment is highly suitable for processing medium-sized workpieces that can be hung, especially parts with complex inner cavities and high requirements for cleaning uniformity:

Auto Parts: engine cylinder block, cylinder head, crankshaft, connecting rod, etc.

General Machinery: motor housing, gears, water pumps, valves, etc.

Casting and Forging Parts: various small and medium-sized steel castings, iron castings and forgings.

5. Usage Recommendations

Balance between Efficiency and Tightness: If production efficiency is the top priority, the Q38 continuous type is the first choice; if more attention is paid to environmental protection and shot material loss, or workpieces have complex shapes requiring longer cleaning time, the Q48 stepping type is a more reliable option.

Focus on Core Components: The quality of blast wheels and the service life of wear-resistant liners are critical to the stable operation of the equipment. Confirm the type of blast wheel adopted by the manufacturer (e.g., Model Q034) and the material of wear liners (e.g., ZGMn13 high manganese steel).

Supporting Systems: High-efficiency shot separators and pulse back-blowing dust removal systems are equally important, as they directly affect the cleaning effect and environmental compliance.

For more precise parameters and quotations, it is recommended to contact the equipment manufacturer directly and provide the maximum size, weight, material of your workpieces as well as the expected production efficiency.
