3. ‌Rubber Hammer and Wooden Wedge‌

• ‌Feature‌In conjunction with lever action for stress relief and fine adjustment.

• ‌Feature‌：

• Hardness: Shore A 50-60 (to prevent indentation marks upon striking)

• Wood楔 Material: African Ebony (Density ≥ 1.1 g/cm³)

• ‌Effect‌: Addressed complex curves such as door creases and wheel arches

‌Section II: Inspection and Auxiliary Equipment‌

1. ‌Coating Thickness Gauge‌

• ‌Accuracy±1μm (Factory Paint Thickness Detection to Prevent Misjudgment)

• ‌UsageEnsure paint surface integrity (thickness fluctuations post-repair must be <5μm)

2. ‌Polarized Light Refraction Detection Lamp‌

• ‌Parameter‌：

• Color Temperature: 5600K (Simulated Natural Light)

• Diameter of Light Spot: 30 cm (covering the detection area)

• Refractive Angle: adjustable from 15° to 75°

• ‌FeatureObserving 0.1mm-level tiny indentations through light interference deformation

3. ‌Vehicle Interior Scope‌

• Resolution: 1080P/60fps

• Bend Angle: 270° Dual-Axis Adjustment

• ‌AppliedA-pillars, sill beams, and other enclosed structures internally repaired

‌Special Scenario Tools‌

1. ‌Dry Ice Jetting Repair System‌

• ‌PrincipleUtilizing -78°C dry ice particles to impact metal surfaces to eliminate micro stresses

• ‌Parameter‌：

• Pressure Range: 0.5-2.0 MPa

• Jet Particle Size: Φ1.5-3.0mm

• ‌ApplicableAluminum alloy body, galvanized steel plate repair and anti-oxidation treatment

2. ‌Electromagnetic Pulse Repair Device‌

• Repair Depth: ≤8mm (for carbon fiber composite materials only)

• ‌ScenarioNew Energy Vehicle Battery Pack Protection Plate, Carbon Fiber Roof Indentation

3. ‌Acoustic Resonance Detector‌

• ‌FeatureDetecting Hidden Metal Fatigue with Sound Waves Between 10-25kHz

• ‌PrecisionIdentifies internal micro-cracks in steel plates with a thickness of 0.8mm (≥0.02mm)

‌Section 4: Enhanced Efficiency Equipment Repairs‌

‌V. Key Technical Points of Tool Usage‌

1. ‌Light Angle ControlAt an angle of 15°-30° between polarized light and concave surfaces, the deformation of light patterns is* pronounced.

2. ‌Temperature Gradient Management‌：

• Winter repairs require preheating to above 15℃ (to prevent metal fracturing)

• The repair temperature of aluminum alloy should not exceed 80℃ (to avoid intergranular corrosion).
