When sourcing an incense making machine, you must evaluate the production capacity (sticks per minute), which typically ranges from 150 to 300 sticks/min for standard automatic models. Pay close attention to the mold diameter compatibility (usually 1.3mm to 5.0mm) to ensure it meets your market's preferences. Additionally, verify the motor power and voltage requirements (e.g., 220V/380V) to ensure compatibility with your local industrial power grid. High-quality machines should feature stainless steel contact parts to prevent corrosion from herbal or chemical additives.
