Production Process
1. Raw Material Cutting
- Utilizing premium diamond cutting heads, we achieve precise cutting of materials with thicknesses ranging from 0.1mm to 5.0mm.
- Our capabilities support a wide variety of shapes—including square, circular, and custom profiles—to accommodate diverse application requirements.
- With meticulous craftsmanship, we ensure a tight dimensional tolerance of ±0.05mm, delivering exceptional precision and quality.
2. Dual-Axis CNC Precision Machining
Our dual-axis CNC equipment is capable of beveling, chamfering, drilling, slotting, and custom profile fabrication.
Beveling: Supports C-edge, R-edge, and 2.5D curved edges.
Chamfering: Handles C-angle, R-angle, and complex chamfers with a minimum tolerance of ±0.05mm.
Drilling & Slotting: Enables high-precision hole drilling and slot cutting on glass, delivering efficiency and accuracy to meet diverse machining requirements.
3. Ultrasonic Cleaning
Each glass piece undergoes a 10-stage purified water ultrasonic cleaning process, thoroughly removing oil stains, dirt, and chemical residues from the surface. This multi-stage purification ensures optimal cleanliness, laying a solid foundation for subsequent processing and defining the final product quality.
4. Chemical Strengthening
Through a precise controlled process comprising 2-hour preheating, 4-hour chemical strengthening, and 4-hour cooling, we apply stringent parameters to treat both soda-lime glass and high-alumina silicate glass. Post-treatment results demonstrate:
Soda-lime glass:
· Surface compressive stress (CS) >450 MPa
· Depth of layer (DOL) >8 μm
High-alumina silicate glass:
· Surface compressive stress (CS) >650 MPa
· Depth of layer (DOL) >40μm
The process delivers remarkable performance enhancement, achieving up to IK08 drop-ball impact resistance standard for exceptional durability.
5. Physical Strengthening (Thermal Tempering)
Our physical strengthening process is suitable for glass with 2.0mm and greater thickness. Through advanced treatment technology, the tempered glass achieves:
Fragmentation control: When shattered, generates >40 fragments within a 50×50mm area, all in blunt-angle morphology, effectively eliminating sharp debris hazards.
Small-size compatibility: Capable of tempering glass as small as 75×75mm, maintaining high performance standards.
6. Printing Process
Utilizing fully automatic printing equipment, and with 80% of inks from Seiko (Japan) High-Performance series, we achieve:
Precision multi-layer registration for complex patterns (10+ layers)
Specialized ink compatibility:
High-temperature ceramic inks
IR (infrared) inks
Metallic inks
Outdoor-grade UV-resistant inks (1,250+ hours accelerated weathering test) ensuring:
Zero fading/discoloration
Superior adhesion under prolonged sun/rain exposure
7. Printing Curing & Baking
Our facility features dual-mode curing systems—flatbed UV curing units and professional convection ovens—enabling:
Precision temperature control to activate physic-chemical bonding between inks and glass substrates
Enhanced adhesion through optimized thermal reaction parameters
Post-curing QC:
100% of products undergo 4B Cross-Cut Test (ASTM D3359) to verify:
Ink adhesion strength ≥4B (＜5% detachment)
Long-term durability compliance
8. Adhesive & Film Lamination
Capable of handling various double-sided films, explosion-proof films, heat-insulating films, and AB adhesive materials.
Equipped with high-precision alignment systems and a dust-free working environment to ensure:
Bubble-free adhesion
Full functional performance (protection/insulation/sealing)
Compliance with diverse industry requirements
9. Final Inspection
All glass products undergo:
100% visual inspection by QC specialists (5+ years experience) checking for:
Surface scratches · Bubbles · Color deviations
AQL-0.65 random sampling inspection for guaranteed quality consistency
10. Packaging
Each glass piece receives dual-sided PE protective film covering against dust/moisture/scratches
Vacuum-sealed packaging prevents oxidation/humidity damage
Customized heavy-duty cartons or wooden crates with EPE foam inserts for:
Shock absorption、Stacking pressure resistance 、Long-distance transport safety
