Proshine Cartridge Filling Gun 50ML
The Proshine gun features a 50 ml barrel with a minimum scale of 1 ml, allowing precise dosing in 1–5 ml steps. It’s designed for continuous filling thanks to its large capacity. The kit includes five lure-lock needle sizes (12#, 13#, 14#, 15#, 16#), two needles per size, and a syringe adapter to switch from cartridges to darts. A heated pad provides fast, even heating for smooth oil flow. Best for users who value continuous filling, versatile needle choices, and consistent heating in one setup.
Who it’s best for: small-scale cartridge producers, DIY oil users, and enthusiasts needing adjustable dosing and reliable heat control. Limitation: not ideal for very viscous formulations that require higher temperatures or more aggressive pumping actions beyond the included needle sizes.
Crossing Upgrade 50ml Cartridge Filling Machine
This model fills up to 50 units of 1 ml in about 5 minutes and switches oils in roughly 60 seconds. It uses an easy-to-read dial for 1 ml increments and includes an annular heat barrel that heats the oil indirectly, protecting your product from direct heater contact. The semi-automatic gun delivers precise dosing with a heated syringe for smooth oil flow. Best for fast throughput with strong protection against oil scorching. Choose this if you need a balance of speed, precision, and oil safety.
Best for: operators who want rapid, repeatable 1 ml dosing with reliable heat management. Limitation: more complex setup than basic handheld guns; requires attention to the heated barrel operation and maintenance of the annular heating system.
Crossing Handheld 50ml Two-Tube Cartridge Filler
This handheld filler uses a 50 ml capacity and features a precision dial with 1 ml increments. It boasts an annular heat barrel to prevent oil burning and ensures a no-drip, stainless steel piston with a Luer lock tip for clean, accurate dosing. Best for portable setups and on-the-go filling tasks. Better for small batches and quick changes between oils; avoid this if you need heavy automation or very large-volume production.
Best for: compact operations requiring portability and precise manual control. Limitation: pacing and workload depend on operator consistency; not ideal for high-volume production without additional equipment.
Moonshan 2-300g Liquid Filling Machine
This fully automatic, 3-in-1 weighing filling machine uses a digital control panel to tare, start, and adjust speed, filling up to 300 g bottles with precision. A hygienic peristaltic pump keeps liquid in contact only with silicone tubing, reducing contamination risks. It offers weight-based, time-based, and price-based modes for flexible operation. Best for those who need automated, multi-mode filling with hygienic pumping. Limitation: designed for lighter, non-viscous liquids; ensure compatibility with your product’s viscosity and material compatibility.
Best for: small-to-medium batches requiring automated weighing and three fill modes. Limitation: may be less efficient for very viscous substances or bottles outside typical dimensions.
Hanchen Peristaltic Bottle Filler 5 Oz
Hanchen’s 5 oz bottle filler uses a two-nozzle peristaltic pump design. It is noted for high accuracy (about ±1%) and suitability for small bottles, with a focus on easy cleaning since the tubing is replaceable. Best for small-bottle bottling and less viscous liquids. Caution: viscous or particulate-laden liquids may challenge accuracy or tubing integrity; verify tubing compatibility with your formula.
Buying guide: key considerations for selecting an oil cartridge filling machine
- Volume and capacity: Do you need handheld portability or a benchtop unit with higher continuous fill capacity?
- Viscosity compatibility: Are your oils thin, thick, or particulate-rich? Peristaltic pumps excel with liquids that don’t clog tubing.
- Heating method: Is indirect heating (annular/heated syringe) enough to prevent burning without overheating?
- Dosing precision: Do you require 1 ml increments or larger steps for faster throughput?
- Feed system and hygiene: Do you need replaceable tubing and easy cleaning to prevent cross-contamination?
- Adaptability: Are multiple needle sizes or adapters important for switching between cartridge and dart formats?
FAQ
- What dosing precision should I expect from these machines? Many offer 1 ml increments with ±1% accuracy depending on the model and viscosity of the oil.
- Can these machines handle different bottle sizes? Some units support 0–300 g or 50 ml cartridges, while others are dedicated to specific capacities; verify your bottle dimensions before purchase.
- Is heating necessary for all oils? Heating helps especially with thicker oils; check the product’s heating mechanism to ensure compatibility with your material.
- Are replacement parts available? Many use replaceable tubing and standard needle sizes; confirm availability of needles and adapters in the kit.
- Is automation required for high volume? For larger volumes, benchtop automatic or semi-automatic models are recommended over handheld devices.
- What maintenance is typical? Regular cleaning of tubing, nozzles, and seals reduces cross-contamination and maintains dosing accuracy.
