Coil Head Assemblies: The complete, pre-built coil unit ready for mass installation into pods or sub-ohm tanks. This includes the coil wire (Kanthal, NiChrome, SS), the wicking material (organic cotton, ceramic), the metal housing, and the rubber insulating grommet and positive pin.Child-Resistant Packaging Disposables: Utilize specialized packaging that meets specific international safety regulations (like CRC in the US). This often involves push-and-turn or squeeze-to-open mechanisms that are difficult for children to open but accessible for adults, which is a critical requirement for market access in many regions.https://cbu01.alicdn.com/img/ibank/2016/245/366/3234663542_1094337179.220x220xz.jpgDual Battery Box Mod Kits: The workhorses of the advanced vaping world. Using two 18650 batteries in series, they provide extended battery life and significantly higher power output (often 200W+), enabling intense cloud-chasing and high-performance vaping. Their larger size is a trade-off for all-day power.510 Connectors: The industry-standard threaded interface that connects a tank to a mod. It consists of a threaded outer ring and a positive pin insulated from the outer threading. Manufacturing these to precise tolerances is critical for universal compatibility, reliable conductivity, and preventing e-liquid leakage onto the mod.
