Automotive Hook Type Pass Through Shot Blasting Machine for Continuous Operation in Metal Cleaning

The pass-through monorail shot blasting machine is a high-efficiency continuous surface treatment equipment. Equipped with an overhead monorail conveyor, it transports workpieces through an enclosed blasting chamber. High-speed abrasives including steel shots and grit strike workpiece surfaces to eliminate impurities and optimize surface performance, making it ideal for mass and batch production of metal parts.

• Continuous and Automated Surface Cleaning
  • Realizes uninterrupted processing: Workpieces are hung on the monorail hanger, automatically entering, passing through the blasting zone, and exiting the chamber, without manual handling in the middle.
  • Strong cleaning capacity: It can quickly remove rust, scale, oxide layers, welding slag, oil stains, and old paint films on the surface of workpieces. The cleaning uniformity is high, and the surface roughness can be controlled stably (generally Ra 1.6-6.3 μm).
• Surface Strengthening Function
  • Through controlled shot peening, the surface of metal workpieces (such as steel structural parts, castings, forgings) forms a residual compressive stress layer, which effectively improves the fatigue resistance and service life of the workpiece, and is suitable for parts subject to dynamic loads (e.g., automotive chassis parts, engineering machinery components).
• Adaptability to Workpiece Size and Shape
  • The monorail conveying system can adapt to workpieces of different weights (from tens of kilograms to several tons) and shapes (such as structural components, pipe fittings, hardware tools, and small-to-medium-sized castings/forgings).
  • Adjustable process parameters: The blasting speed, abrasive flow rate, and monorail running speed can be adjusted according to the workpiece material and surface requirements to meet different treatment standards.
• High Environmental Protection and Resource Utilization
  • Equipped with a sealed blasting chamber + dust removal system, which effectively collects dust and abrasive particles, reduces dust emission, and meets environmental protection requirements.
  • Integrated abrasive recycling system: The used abrasive is screened, separated (to remove impurities such as dust and oxide skin), and recycled, which reduces abrasive consumption and production costs.
• Compatible with Subsequent Process Linkage
  • Seamlessly integrated with painting, spraying and electrophoresis, it forms a complete surface treatment line. Higher production efficiency is achieved, and the roughened workpiece surface effectively improves coating adhesion.
