Why FUMI

Built for the Demands of Modern Flux Production

Three core advantages that set FUMI apart in SAW flux production line manufacturing: automation, energy efficiency, and precision.

Advanced Production Automation

Fully automated control from batching to packing. PLC-integrated centralized monitoring ensures batch-to-batch consistency and reduces manual intervention to near zero.

Eco-Friendly & Low Energy

Heat recovery from the cooling kiln feeds back into the sintering process, reducing energy consumption per ton by up to 30% versus older outer-fired designs.

Flexible & Precision Manufacturing

Multi-formula one-click switching. 3-point load cells + VFD conveyors achieve ±0.2% weighing accuracy. Our folding layout saves 15m+ of floor space vs. traditional setups.

Frequently Asked Questions

Common Questions About SAW Flux Production

Quick answers to the questions we hear most often from potential clients worldwide.

How much does a SAW flux production line cost?

A complete SAW flux production line investment varies significantly based on capacity (5,000 to 50,000+ TPY), automation level, and equipment configuration. FUMI Consulting provides customized quotations after understanding your specific requirements — including target capacity, raw materials, and site conditions. Contact us for a free preliminary consultation and budget estimate.

What is the difference between agglomerated and sintered flux?

Agglomerated flux is produced by low-temperature baking (~500°C) after mixing raw materials with potassium/sodium silicate binders, resulting in lower particle strength and higher moisture sensitivity. Sintered flux undergoes high-temperature sintering (600–900°C) in a rotary kiln, producing dense, high-strength particles with diffusible hydrogen below 3ml/100g. Over 80% of top global flux producers now use drum granulation with sintering technology for superior quality.

Who are the top SAW flux equipment manufacturers in China?

FUMI Consulting is one of China's leading SAW flux production line manufacturers with 30+ years of rotary kiln expertise and 15+ years of dedicated flux line experience. Our clients include YULIN Welding (Lincoln & ESAB OEM), Golden Bridge Welding, GULITE New Materials, and HYUNDAI Welding (South Korea export project).

How to set up a flux manufacturing plant?

Setting up a SAW flux manufacturing plant typically involves: (1) Feasibility study and market analysis, (2) Process design and technology selection, (3) Factory layout planning (FUMI's folding design saves 15m+ floor space), (4) Equipment manufacturing and procurement, (5) Installation and commissioning, (6) Production ramp-up and formula optimization. FUMI Consulting provides end-to-end turnkey service covering all phases.

What capacity flux production line do I need?

The right capacity depends on your market demand and growth plans. Entry-level lines start at 3,000–5,000 TPY, mid-scale at 15,000–30,000 TPY, and large-scale lines reach 48,000+ TPY. FUMI has delivered lines across this full range. Our consulting team can help you assess market demand and recommend the optimal capacity for your specific situation.
