Scrapers made of laser-cut copper sheets, hand-welded
Shield Body Structure:
Segmented steel frame, laser-welded
Micro bearings built into hinge joints
Tube segment assembly machine tracks CNC precision milled
2. Hydraulic System Restoration
Thrust Cylinders:
Aluminium alloy cylinder bodies anodised
Piston rods mirror-polished and coloured
Hydraulic hoses silicone injection moulded
Piping Layout:
Main oil lines made of copper tubing heat-bent into shape
Valve assemblies 3D-printed with resin and coloured
3. Professional Coating Solution
Base treatment:
Full-piece sandblasting for degreasing and desizing
Epoxy primer electrostatic spraying
High-temperature baking curing
Industrial texture:
Hydraulic oil stain glaze layered painting
Worn areas dry-brushed for an aged look
Safety markings using transfer printing process
IV. Dynamic display system
Movable Mechanisms:
Rotating blade disc with variable-speed motor
Extendable hydraulic cylinder
Tube segment assembly robotic arm
Lighting Effects:
LED spotlights on the excavation face
Red light flow in the hydraulic system
Backlit buttons on the control panel
