The materials used for e-cigarette casings are diverse, with common options including plastic, stainless steel, aluminum alloy, zinc alloy, glass, ceramic, and liquid silicone. Each material has its own characteristics and is suitable for various design and functional requirements.
1. Plastic Materials
PCTG
This material offers glass-like transparency and density, with excellent food safety and flame resistance properties. It is free from Bisphenol A (BPA). PCTG is always use for the tank of CBD and THC disposable vape.
PC (Polycarbonate)
Known for its transparency, impact resistance, and dimensional stability, PC is commonly used in e-cigarette atomizer tanks and mouthpieces. PC materials always use for standard casing of disposable vape pens.
2. Metal Materials
Aluminum Alloy
Lightweight and strong, aluminum alloys can achieve a matte finish through surface treatments like anodizing, enhancing the tactile feel. The e-cigarette brand Juul, based in the United States, uses aluminum extrusions for its casing.
Stainless Steel
Durable and corrosion-resistant, stainless steel is more costly but suitable for high-end e-cigarette products. Stainless steel material often used for regular-shaped vape pens and vape batteries.
Zinc Alloy
This material is also lightweight and strong and can be shaped into complex forms through processes such as die casting, making it suitable for e-cigarette casings.
3. Other Materials
Paper Tubes
An environmentally friendly option, but not widely used due to issues with strength and cost. In certain cases, such as disposable e-cigarettes or products with specific designs, paper tubes may be used for their lightweight and portable characteristics.
Glass
Attractive and provides a good tactile experience, but is costly and fragile, so it is generally used for decorative elements. The 3D glass thermal bending molding process is widely used in e-cigarette casing production, enabling seamless molding and enhancing aesthetic appeal.
Ceramic
Resistant to high temperatures and corrosion, but also expensive and difficult to process. Some e-cigarette brands have attempted to use ceramic for components like vape cartridges, but large-scale production has not been achieved.
Liquid Silicone
Non-toxic, odorless, highly transparent, soft, and elastic, with resistance to twisting and deformation. It has a long service life and withstands both cold and high temperatures. It is widely used in e-cigarette mouthpiece silicone covers, seals, and casings. OSKVAPE B07 is the vape battery with silicone casing.
Summary
The choice of material for e-cigarette casings depends on various factors, including design requirements, cost considerations, processing difficulty, and user experience. Each material has its own advantages and disadvantages, and manufacturers select and optimize based on practical needs. With ongoing technological advancements and market development, new materials and processes will continue to emerge, bringing more innovation and possibilities to the e-cigarette industry.
