Manufacturing Capabilities

Frequently Asked Questions

1. How long does the equipment production take?

The standard production cycle is 30-70 days depending on customization. Detailed timelines are provided after technical plan confirmation.

2. What information is needed for a customized quote?

Please provide workpiece type, dimensions, weight, expected daily output, coating process requirements, and available factory space.

3. Is on-site installation provided?

Yes, professional engineers provide turnkey installation and commissioning (typically 30-60 days) until the equipment operates stably.

4. What is the warranty and after-sales support?

We offer a 12-month warranty, remote technical debugging within 2 hours, and on-site support for major mechanical failures.

5. What is the temperature control accuracy of the furnace?

The system maintains a temperature control accuracy of ±2℃, with uniformity within the furnace kept at ≤±5℃.

6. How does the system achieve energy saving?

Through a composite insulation layer (high-alumina refractory brick) and a flue gas waste heat recovery exchanger that preheats combustion air, reaching a utilization rate of ≥72%.
