Liquid and flavor system
Provide viscosity, VG/PG direction, nicotine system and any ingredients that may affect wicking or residue.
Core Technologies / Ceramic / Mesh Coil
Ceramic & Mesh Coil Technology
Choose ceramic or mesh by liquid, airflow, power and draw.
02
Changhan Technology
Compatibility First
The coil is approved as part of a device, liquid, airflow and power system.
Atomization Decision
Choose the Right Coil
Choose ceramic or mesh by liquid, airflow, power, device shape and draw.
Draw and output target
Define MTL or DTL direction, airflow range, resistance target and target power range.
Device envelope
Share reservoir, chimney, contact, assembly and available atomizer dimensions.
Design Variables
Coil-to-Product Matching
Match heating area, resistance, wicking and airflow to the intended device and liquid.
Heating area
Surface geometry changes heat distribution, ramp behavior and contact with the wick or ceramic body.
Resistance tolerance
Target and allowable variation must match the chipset, output mode and protection logic.
Wicking rate
Liquid supply must recover between draws without flooding the air path or drying the heating surface.
Air path
Inlet, chamber and outlet geometry influence draw resistance, cooling and aerosol delivery.
Resistance and output
Measure resistance distribution and behavior across the agreed power range.
Saturation and recovery
Observe startup, repeat draws and recovery under the defined use pattern.
Flavor and aerosol review
Use an approved evaluation method and reference liquid for sensory comparison.
Leakage and dry-hit checks
Review storage, orientation, draw sequence and temperature conditions relevant to the product.
Engineering Output
An approved coil, liquid, airflow and power combination with stated tolerances and test conditions.
