We are a leading Manufacturer of Disposable Vapes and Zirconia Ceramic 510 Cartridges based in Shenzhen, China. Since 2015, we have focused on OEM/ODM manufacturing of premium Zirconia Ceramic 510 Cartridges, Vape Pens, and 510 Thread Batteries.
Quality First
Quality is our top priority. We produce only high-standard cartridges, overseeing every step from material selection and quality control to production, testing, and packaging. All raw materials—including hardware metals, ceramic cores, glass, plastics, and silicones—are sourced from reputable suppliers known for consistency and reliability, even when this means higher material costs.
Skilled Production & Innovation
Our 10 production lines are staffed with highly skilled workers who minimize errors in handmade processes. We employ custom-designed semi- or fully-automated machines for assembly and testing, ensuring secure ceramic mouthpieces with very low cap-off rates. Our cotton-wrapped ceramic heating elements are optimized for pure flavor and consistent vapor performance. Continuous research and improvement are integral to our production process.
Global OEM Partnerships
We specialize in OEM services for custom-branded products and have collaborated with over 600 brands worldwide, with approximately 80% based in the United States and Canada. Our partnerships are built on reliability and trust.
We always welcome new collaborations—let’s work together!
