Factory & QC
One Roof: Design, Machining, Assembly, Calibration
Published workshop photographs provide context. Request the model-specific production, testing and acceptance records relevant to your order.
How Your Analyzer Is Built
Machining
Frame, turntable and feeding mechanisms machined and inspected.
Assembly
Furnace, balance, electronics and pneumatics integrated per model SOP.
Testing & acceptance
Agree the model-specific test record and factory acceptance criteria before shipment.
Export packing
Fumigation-free wooden cases, shock indicators, sea/air worthy.
Four Core Workshops
Mechanical Workshop
CNC machining centers and sheet-metal lines produce frames, turntables and sample-handling mechanisms in-house — tolerance control stays in our hands, not a supplier's.
Electronics Assembly
DSP controller boards, wiring harnesses and touch terminals are assembled and aged on SMT lines with ESD controls, powering every analyzer model.
Furnace & Heater Winding
Round-well furnaces, silicon-molybdenum and SiC heaters are wound and filled in-house — the core of our 1050–1600 °C temperature control.
Calibration & Metrology
Imported reference balances, certified thermocouples and CRMs for each coal rank verify every unit against GB/T, ISO and ASTM requirements.

Quality Management
- Quality-system documents can be requested for review
- Incoming inspection on balances, thermocouples and imported key components
- Model-specific testing and reference-material records can be requested
- Serialized production records — every unit traceable to its build sheet
- Third-party inspection scope can be discussed for a defined order
Video factory tour before you order
We regularly host live walk-throughs for overseas buyers: see the line running your model, watch a CRM verification, and meet the engineers who will support you after delivery.
