Shot Blasting Pre-treatment System

Product Overview

The shot blasting pre-treatment system is designed to remove rust, scale, welding residue, and surface contaminants from metal workpieces before coating. By propelling abrasive media at high speed onto the surface, it creates a clean and uniform substrate, improving coating adhesion and overall durability.

This type of pre-treatment is widely used in powder coating lines, painting systems, and heavy-duty industrial finishing applications where higher surface cleanliness and roughness consistency are required.

Key Features

Consistent Surface Preparation

Shot blasting ensures uniform cleaning results across complex geometries, helping achieve stable coating quality in subsequent processes.

Enhanced Coating Adhesion

The process forms an ideal anchor profile on the metal surface, supporting better bonding between the substrate and coating layer.

High Throughput Capability

Designed for continuous operation, the system can be integrated into automated production lines to match different production capacities.

Flexible Equipment Configuration

Available in multiple formats such as hanger type, roller conveyor type, and tunnel type systems, depending on workpiece size, weight, and production flow.

System Components

Shot blasting chamber

Turbine blasting units

Abrasive circulation and separation system

Dust collection and filtration system

Required surface cleanliness level (e.g., Sa2.5)

Production capacity and line speed

Abrasive type and recycling efficiency

Integration with downstream coating processes

Why Choose Shot Blasting Pre-treatment

Compared with chemical pre-treatment methods, shot blasting provides a dry and environmentally manageable solution, reducing water usage and chemical discharge. It is especially suitable for applications where strong mechanical cleaning and stable surface roughness are required.
