Products & Instruments
Mihana Tech operates some of the world's most specialised VIG and vacuum science instrumentation โ built over four decades of focused research. Each instrument below represents a genuine capability, not an off-the-shelf service. Many of these systems were designed and built in-house specifically for the demands of VIG and vacuum science. We also design and build systems to client specification for those who want these capabilities in their own facility.
VIG Testing & Measurement Instruments
Guarded Hot Plate (GHP) System
World-unique capabilityOur custom guarded hot plate system measures thermal transmittance at a spatial resolution that resolves heat flow through a single sub-millimetre support pillar at milliwatt precision. No comparable commercial instrument exists anywhere in the world.
- U-value measurement from 1.0 down to 0.4 W mโปยฒ Kโปยน
- Pillar-scale heat flow resolution at milliwatt precision
- Full VIG panel and component-level assessment
- Combined HotBox measurements for frame-level evaluation
- Traceable calibration for standards compliance (NFRC, ISO)
Surface Wave Analysis
Acoustic characterisationSurface wave measurement techniques for acoustic and mechanical characterisation of glass panels and VIG units. Supports sound transmission loss assessment and structural integrity evaluation โ increasingly important as VIG competes on acoustic performance alongside thermal insulation.
- Sound transmission loss assessment for VIG units
- Standards-relevant acoustic performance testing
- Structural integrity and defect detection
- Comparative analysis across panel configurations
Pillar Test Rig
Component-scale testingDedicated test infrastructure for characterising individual support pillars โ the most thermally and mechanically critical component in a VIG. Component-scale insight essential for pillar design optimisation. This level of testing is unique to Mihana Tech.
- Compressive strength and elastic/plastic deformation
- Friction and shear response characterisation
- Local thermal conductance measurement
- Geometry, material and surface condition variables
- FEM simulation support for results interpretation
Mechanical & Load Testing
Structural validationStructural response and failure assessment of glass plates, IGU and VIG units across the full range of relevant loading conditions. Supported by FEM simulation for rigorous analytical interpretation and direct extrapolation to product design.
- Point-load and uniform wind pressure testing
- Thermal gradient and HotBox thermal loading
- Impact testing and failure analysis
- FEM simulation and design extrapolation
- Standards-relevant test protocols
Vacuum & Gas Analysis Instruments
Residual Gas Analysis (RGA) & Gas Testing
Vacuum scienceSpecialised vacuum instrumentation for outgassing assessment, cavity pressure evolution, getter performance and residual gas identification. These measurements directly inform seal design, manufacturing process parameters and VIG lifetime prediction โ the defining challenge of VIG manufacturing.
