As the CBD and cannabis vape market continues to evolve, product innovation is no longer limited to hardware design alone. Today, brands are differentiating themselves through oil formulations, flavor combinations, and multi-effect experiences. One of the fastest-growing trends is dual-flavor and dual-formula vape cartridges—and traditional filling methods are no longer sufficient to support this shift.

To meet this emerging demand, Longwill Machinery has developed a Dual Oil Tank Semi-Automatic Cartridge Filling Machine, specifically designed for filling two different oils into a single cartridge with precision, efficiency, and control.

Designed for the Rise of Dual-Flavor & Dual-Formula Cartridges

Single-flavor CBD cartridges are becoming increasingly commoditized. In response, more brands are introducing innovative products such as:

• Dual-flavor cartridges

• CBD + minor cannabinoid blends (CBN, CBG, etc.)

• Day/Night or function-based oil combinations

• Terpene-forward formulations with layered flavor profiles

While these products stand out on the shelf, they introduce new challenges in production. Using a single oil tank machine requires frequent oil changes, repeated cleaning, and increases the risk of cross-contamination. Fully automated dual-oil systems, on the other hand, are often costly and overly complex for small to mid-sized brands.

Our dual oil tank semi-auto solution is built precisely for this gap.

Dual Oil Tank & Dual Nozzle Configuration

This machine features two independent oil tanks, each paired with its own filling nozzle. The system allows operators to:

• Load two different oils simultaneously

• Maintain independent temperature control for each oil

• Prevent flavor mixing or residue contamination

• Fill cartridges with two oils in a controlled sequence or ratio

Whether you are working with different viscosities, terpene profiles, or cannabinoid formulations, the dual-tank design ensures stability and consistency throughout the filling process.

Semi-Automatic Control for Maximum Flexibility

Unlike fully automated systems, this machine is intentionally designed as a semi-automatic solution with hand-held filling control.

Why semi-auto?

• Dual-oil cartridges often require human judgment, especially during R&D or early production stages

• Oil behavior can vary depending on formulation, temperature, and ratio

• Operators can visually monitor oil flow and adjust in real time

This balance between automation and manual control allows brands to scale beyond hand filling—without losing flexibility or committing to full automation too early.

Ideal for Product Development and Scalable Production

The Dual Oil Tank Semi-Auto Cartridge Filling Machine is especially suitable for:

• Brands launching new dual-flavor or blended oil products

• Small to medium batch production

• Market testing before full-scale automation

• Manufacturers with multiple SKUs and frequent oil changes

It enables faster changeovers, reduced downtime, and a more efficient workflow compared to traditional single-oil filling setups.

Key Benefits at a Glance

• Supports two different oils in one cartridge

• Reduces cleaning time and oil waste

• Improves filling consistency and product quality

• Lower investment compared to full automatic lines

• Ideal bridge between manual filling and automation
