Multi‑hole Quartz Gas Diffusion Plate for New‑energy Research Laboratory-sara
Pubblicato il: September 12, 2026
Title: Multi‑array Drilled Quartz Plate for Fuel‑cell Gas‑diffusion Test Bench
Customer Background: Overseas university new‑energy research laboratory
Customer Requirement:
Quartz glass plate with hexagonal‑arranged through‑holes, aperture range 2 mm‑8 mm, working temperature up to 1100 °C, no deformation under cyclic high‑temperature atmosphere. Flatness and hole‑position accuracy directly affect gas diffusion uniformity for fuel‑cell R&D experiments.
Our Solution:
Adopt high‑purity JGS1 quartz raw material. Program‑controlled CNC ultrasonic drilling for hexagonal hole array, followed by stress‑relief annealing and double‑sided optical polishing. Strict hole‑spacing tolerance ±0.03 mm.
Project Result:
Gas‑diffusion uniformity reaches above 94%. The plate has run continuously for 7‑month cyclic high‑temperature experiments without crack or distortion. The laboratory places repeat orders for follow‑up research batches.
Case Study 2: Micro‑drilled Quartz Vacuum Carrier Plate for Optical Equipment Manufacturer
Title: Precision Micro‑hole Drilled Quartz Vacuum Chuck Plate for Optical Coating Equipment
Customer Background: European optical equipment manufacturer
Customer Requirement:
Thick quartz plate with dense micro‑hole array for vacuum adsorption. Aperture 0.3 mm, hole pitch 1.5 mm. No micro‑cracks around holes. The plate works under vacuum & high‑UV environment for lens‑coating positioning fixtures. Traditional mechanical drilling easily brings chipping and hidden micro‑cracks.
Our Solution:
Picosecond laser precision drilling with gradient‑energy parameter to minimize heat‑affected zone. Post‑process chemical polishing & full annealing. Every hole is inspected under metallurgical microscope.
Project Result:
Zero hole‑edge micro‑cracks found in acceptance test. Vacuum‑adsorption performance fully meets the machine specification. Customer transfers all this‑type quartz component sourcing to our company after sample validation.
