Frequently Asked Questions
I. Equipment Performance & Application
1. What types of glass can the VIBRAN flat & bent combined tempering machine process?
The machine is compatible with various architectural glass, including flat/bent tempered glass, ultra-clear glass, LOW-E glass (offline/online), silk-screen printed glass, embossed glass, and colored glass. It supports glass thickness ranging from 4mm to 25mm, with minimum size 300×300mm and maximum size 3.0×6.0m, meeting demands for curtain walls, windows, doors, and decorative glass.
2. What is the production capacity of the machine?
The production capacity of our Automotive Glass Bending & Tempering Furnace depends on glass size, thickness, and process requirements.
For automotive rear and side windows, the typical capacity is approximately 60 pieces per hour, with stable performance and high yield. We can also provide a customized solution and accurate capacity data based on your specific product specifications.
3. Does the machine comply with international standards?
Yes. The tempered glass produced meets global standards such as ISO 12543 (tempered glass for buildings), CE (EU), and ASTM C1048 (US). The machine itself is manufactured in accordance with IEC 60204 (electrical safety) and GB/T 20186 (Chinese glass tempering equipment standards), ensuring compliance with import requirements of major markets.
II. Core Components & Quality
4. What material is the heating element (furnace wire) made of, and what is its service life?
We use high-performance FeCrAl alloy or Nichrom heating wires (optional premium grade). Key features include high temperature resistance (up to 1400℃), corrosion resistance, and stable heating. Under normal operating conditions (8-10 hours/day, regular maintenance), the service life is 12-18 months. We also provide original replacement wires for quick maintenance.
5. What type of insulation material is used in the furnace, and how effective is it?
The furnace lining adopts high-quality aluminum silicate (ceramic fiber) cotton, with continuous operating temperature 1000-1200℃ and thermal conductivity as low as 0.025 W/(m*K). It minimizes heat loss (energy saving 25-40% compared to traditional machines) and keeps the furnace surface temperature ≤50℃ for safe operation.
6. How to ensure the optical quality of tempered glass (no wind spots/stress spots)?
The machine uses a cold-riveted air grid with 0.05mm precision adjustment for air knife spacing. Equipped with patented micro-injection nozzles, it delivers uniform cooling airflow. Combined with optimized heating curves, it reduces defects like wind spots and stress spots, ensuring the finished glass has high transparency and flatness (conforming to ISO 12543-2 optical standards).
III. Operation & Maintenance
7. Is the machine easy to operate, and what training is provided?
The machine features a PLC touchscreen control system with one-click parameter recall (stores up to 100+ process recipes). No professional programming skills are required--operators can master basic operations in 1-2 days. We provide free on-site training, including machine setup, parameter adjustment, and troubleshooting. A detailed English operation manual and video tutorials are also included.
8. What is the maintenance cycle, and how to reduce downtime?
Daily maintenance: Clean the roller table, check heating wire status, and inspect air pressure. Monthly maintenance: Tighten electrical connections, calibrate temperature sensors, and clean the air grid. Annual maintenance: Replace insulation cotton, inspect servo motors, and overhaul the quenching system. The machine is equipped with remote monitoring (optional), allowing our technicians to diagnose faults remotely and reduce downtime to 4-8 hours (for common issues). We also stock key spare parts in regional warehouses for quick delivery.
9. How to handle glass breakage or jamming during operation?
The machine is installed with high-sensitivity glass position sensors. In case of jamming, it automatically stops feeding and triggers an alarm. The furnace door can be opened manually for safe glass removal. Our technical team provides 24/7 support to guide you through emergency handling via video call.
IV. Order & After-Sales
10. What is the lead time for the machine?
Machine lead time: 90-150 working days (standard model); 90 working days (customized model).
11. Do you provide installation and after-sales support?
Yes. We offer turnkey solutions, including: On-site installation and commissioning by certified engineers (30-40 working days). 1-year warranty for the entire machine (2 years for core components like PLC and servo motors). Lifelong technical support: 24/7 hotline, remote diagnosis, and on-site service (response within 48 hours for nearby regions).
12. Can you customize the machine according to specific requirements?
Absolutely. Customization options include: Glass size range (e.g., larger bending radius for curved glass). Production capacity (e.g., high-speed lines for mass production). Special functions (e.g., automatic loading/unloading, remote monitoring). Localized electrical standards (110V/220V/380V, 50/60Hz) to match your regional power supply.
V. Pricing & Payment
13. What is the pricing structure, and are there any hidden costs?
Our pricing includes the machine, core accessories (heating wires, insulation cotton), installation tools, and training. No hidden costs--additional expenses (if any) will be clearly stated in the contract, such as shipping fees, customs duties, or optional accessories (e.g., extended warranty).
14. What payment terms do you accept?
We support flexible payment methods for B2B cooperation:
T/T (Telegraphic Transfer): 30% advance payment, 65% payment before shipment, 5% balance after commissioning.
L/C (Letter of Credit): Accepted for orders above 100,000 USD (via major international banks). Partial payment plans can be negotiated for long-term partnerships. For more customized questions about your project, please contact our sales team for personalized support!
