Encourage entire-process personalization from mold creation to structural design. For instance, we won the annual innovation supplier award after customizing a specifically shaped ceramic PTC heater for a European brand to fit its equipment space constraints.

Develop strategic partnerships with source raw material producers and experiment on key materials' test batches. To guarantee that the performance of every batch of products is constant and to trace the batches of raw materials, the MES system is employed; significant quality concerns can be traced back to the source of raw materials.

Core technologies are ① ultrasonic dewaxing precision casting (accuracy ±0.02mm); ② fully automatic winding cold needle technology (efficiency increased by 50%); ③ multi-layer composite insulation layer process (voltage resistance increased by 3 times). 187 patents have been officially approved.

For quality concerns, apply the "three guarantees" policy (return, replacement, and repair) and unconditionally return and exchange items. Create a quality traceability system whereby problem batches can be rapidly locked and recalled, assuming customer joint losses.

Suli Group's primary subsidiary is Jinzhong Electric Heating. Being a main business of Suli Technology concentrating on clean heating, we combine the resources of the parent firm in electric heating technology research and development, worldwide channel network, and industrial chain integration.
