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

Quality Certification Statement: [Guangdong Jianqiao Testing Equipment Co.,Lltd] 

– Leader in Reliable Vibration Test Tables & Climatic Test Chambers

1. Globally Recognized Certifications: Meeting International Benchmarks

• ISO 9001:2015 Quality Management System Certification: This certification covers our entire production chain—from raw material procurement and R&D design to manufacturing, assembly, and after-sales service. It proves that we have established a standardized, traceable quality control system to ensure consistent product quality across every batch.
• CE Certification (EU): Our products fully comply with the EU’s Machinery Directive (2006/42/EC) and Electromagnetic Compatibility (EMC) Directive (2014/30/EU). For Vibration Test Tables, this means strict control over vibration frequency accuracy (±0.1Hz) and noise levels (<65dB at full load); for Climatic Test Chambers, it guarantees precise control of temperature (-70℃ to +150℃, ±0.5℃) and humidity (10%RH to 98%RH, ±2%RH), meeting the testing needs of industries such as automotive, electronics, and aerospace in the EU.
• GB Standards Compliance (China): In line with national quality requirements, our products meet GB/T 2423 (Environmental Testing for Electrical and Electronic Products) and GB/T 13309 (Vibration Test Machines for Packaging), ensuring compatibility with domestic industrial testing standards.

2. Strict In-House Quality Control: From Design to Delivery

• R&D & Design: Our engineering team uses FEA (Finite Element Analysis) to optimize the structural stability of Vibration Test Tables (e.g., ensuring the tabletop bears up to 500kg without deformation) and simulates extreme climatic conditions (e.g., rapid temperature changes of 10℃/min) for Climatic Test Chambers, ensuring design feasibility before production.
• Raw Material Inspection: Key components—such as high-torque motors for vibration systems, stainless steel inner chambers for climatic chambers, and precision sensors for temperature/humidity control—are sourced from certified suppliers (e.g., Siemens, Omron) and undergo 100% incoming inspection, including material composition testing and performance sampling.
• In-Process Testing: During manufacturing, every Vibration Test Table undergoes a 24-hour continuous vibration test at full frequency range (5Hz to 2000Hz) to check for abnormal noise or performance drift; every Climatic Test Chamber is subjected to a 72-hour cyclic test (alternating high/low temperature and humidity) to verify the stability of its refrigeration, heating, and humidification systems.
• Final Certification & Documentation: Before delivery, each product receives a personalized “Quality Certification Report,” which includes test data (e.g., vibration acceleration accuracy, temperature fluctuation curves), certification marks, and a 2-year warranty commitment. Customers can also request third-party on-site re-testing to confirm compliance.
