Production Line for Vibration Tables & Environmental Chambers

1. Raw Material Preparation

2. Machining & Forming

• CNC Machining Centers: Metal components (frames, chambers, vibration platforms) undergo milling, drilling, and turning to achieve dimensional accuracy within ±0.02mm.
• Sheet Metal Bending: Press brakes form stainless steel sheets into chamber bodies, doors, and vibration table enclosures, with edge rounding for safety and aesthetics.
• Welding & Assembly: Robotic MIG welding ensures airtight seams for environmental chambers, while vibration table bases are reinforced with ribbed structures to withstand dynamic loads up to 2000kgf.

3. Surface Treatment

• Deburring & Polishing: Automated grinding machines remove weld beads, followed by electrolytic polishing for chamber interiors to achieve Ra 0.8μm surface finish, preventing particle adhesion.
• Powder Coating: Exteriors are coated with electrostatic powder (epoxy-polyester hybrid) in RAL 7035 (light gray) or custom colors, baked at 180°C for 20 minutes for corrosion resistance.

4. Subsystem Integration

• Vibration Table Assembly: Integrates servo-hydraulic actuators (for large displacement) or electromagnetic shakers (for high-frequency vibration), paired with precision guide rails and load cells for displacement/force feedback.
• Environmental Chamber Systems: Installs refrigeration units (scroll compressors), heating elements (incoloy sheathed), humidity generators (ultrasonic atomizers), and air circulation fans with HEPA filters.
• Control Panel Mounting: Embeds PLCs (Siemens/Schneider), HMI touchscreens, and sensors (PT100 thermistors, humidity probes, accelerometers) for real-time parameter monitoring.

5. Calibration & Testing

• Vibration Calibration: Uses laser interferometers to verify frequency ranges (5Hz-2000Hz), acceleration (up to 100g), and displacement (peak-to-peak 50mm) compliance with ISO 16063-21.
• Environmental Performance Testing: Chambers undergo temperature cycling (-70°C to +180°C), humidity control (10%-98% RH), and thermal uniformity tests (±0.5°C at 100°C) per IEC 60068-3-5.
• Safety Validation: EMC testing, overload protection checks, and door interlock verification ensure compliance with CE/UL safety standards.

6. Quality Inspection & Packaging
