Core Equipment Craftsmanship

Extreme Craftsmanship for Combined Stress

Aerospace-grade precision that solves seismic, sealing and structural fatigue challenges under high acceleration and deep vacuum.

Multi-Channel Coordinated Intelligent Coupling Algorithm

A built-in high-order matrix algorithm coordinates the dynamic balance of temperature, humidity and pressure, automatically compensating heat during vacuum evacuation to avoid temperature loss.

Dynamic Flexible Thermal Insulation Sealing

The shaker interface uses a proprietary ceramic insulation layer and double-layer silicone rubber sealing, absorbing high-frequency vibration displacement for leak-free low-pressure operation.

Aerospace-Grade Full Weld & Seismic Reinforcement

Thickened SUS304/316L inner liner with full argon-arc welding plus exterior mesh reinforcement withstands pressure differentials and 100g vibration impact.

High-Efficiency Vacuum Evacuation & Gas Replenishment

A high-speed rotary vane vacuum pump with pneumatic isolation and fine-tuning valves delivers rapid, stable decompression, with dust-free dry gas replenishment to protect test samples.

EMC-Grade Anti-Interference Electrical Wiring

Power and signal wiring are fully separated with multi-layer shielded cables, protecting sensors from shaker magnetic fields and high-frequency inverter interference.

Multi-Mode Flexible Assembly Architecture

Integrated or split control-cabinet design based on on-site space, with lifting or translation rails for quick docking with the shaker.
