Oven Patents by Problem Solved
Faster heat-up
2023 Improved preheater: preheating parts shortens the ramp.
2025 Energy-saving faster heat-up system
Heat recovery
2024 Thermal-storage heat recovery: exhaust heat is stored and fed back.
2023 High-efficiency pass-through oven
Special heating
2024 IR array heating module for vacuum: no convection, so IR heats the work directly.
2015 High-power UV-LED: UV curing light source.
Related: heat recovery saves 20-25% energy and recovers 25% of solvents.
Zone control
2024 Real-time per-zone temperature control: each zone measured and tuned alone; one zone's drift won't spoil the batch.
No-stop airflow
2024 Door-closed airflow adjustment: set from outside while running; no heat or cleanliness lost.
Damper sealing
2024 Dual-layer damper: sealing drives N2 use and chamber O2.
Related
- Uniformity tuned while running, no cool-down: ±1.5%.
- Multi-layer dampers seal above 99%.
- Main/aux N2 loops auto-switch flow; O2 down to 10ppm.
High-temp clean chamber
2020 High-temp clean oven structure: keeps the chamber clean in clean inert processes up to 530°C.
Doors and moving parts
2020 Door handle, 2020 bearing housing, 2023 improved gate: these cycle most, so distortion and seal failure start here.
Related
- 99.97% HEPA; cleanliness up to ISO 14644-1 Class 4 @0.3µm.
- Pressure relief keeps positive pressure, an N2 curtain guards the inner door, and a cooling jacket keeps O2 down to 10ppm in cool-down.
Energy Use
Power cost and heat-up time: how heat is made, kept and recovered.
