Proshine 50ML Cartridge Filling Gun
The Proshine 50ML cartridge filling gun is designed for users who need longer runs between recharges. Its 50 ml barrel supports continuous injection with a minimum scale of 1 ml, making it easier to set precise doses at 1–5 ml. The product emphasizes complete accessories, including multiple lure lock needle sizes for solid connections, and a heat pad to improve oil flow. Best for small labs or teams that fill multiple cartridges in one session. A limitation is the need to manage needle changes for different cartridges, which may slow down multi-type runs.
- Best for: Medium- to high-volume cartridge filling with straightforward 1–5 ml dosing.
- Why selected: Large capacity reduces frequent refills, and the heat pad aids even heating of viscous oils.
- Caution: Switching needle types may require additional setup time.
CROSSING Upgrade 50ml Cartridge Filler
This CROSSING model emphasizes efficiency, claiming up to 50 fills of 1 ml in about five minutes and quick oil changes in 60 seconds. It uses an annealed heat barrel with an air gap to heat oil without exposing it to direct heating elements. The dial enables easy increments from 1 to 5 ml for precise dosing. Best for operations prioritizing speed and oil protection. A potential drawback is the need to ensure the annealing chamber remains clean to prevent oil residue buildup.
- Better for: Quick, precise fills with a focus on protecting sensitive oils.
- Why selected: Fast cycle times and oil-protective heating design.
- Caution: Regular cleaning is essential to maintain heat efficiency.
CROSSING Handheld 50ml Cartridge Filler Gun
This handheld CROSSING device features a readable dial for 1–5 ml increments and a stainless steel piston with a no-drip tip to deliver precise doses. It’s built to fill up to 50 units in five minutes and facilitates fast oil changes. The annular heat barrel design reduces direct contact between oil and heating elements, protecting the product. Best for on-the-go operators who need precision without a bulky setup. A limit is its reliance on manual dosing, which may be slower than automated systems for very large batches.
- Choose this if: You need portable, precise filling in smaller workspaces.
- Why selected: Durable design and clear dial enable consistent dosing.
- Caution: Manual operation may be slower for high-volume days.
Proshine 50ML Cartridge Filling Gun (Alternate)
This version mirrors the Proshine 50 ml capacity with a focus on complete accessories, including multiple needle sizes for robust connections and the same heat pad feature. It emphasizes seamless transitions from cartridge to dart filling with a syringe adapter. Best for buyers who want flexibility in accessory options. A caution is ensuring compatible syringe adapters for non-cartridge tasks.
- Best for: Buyers needing flexible accessory compatibility.
- Why selected: Broad needle assortment supports different cartridge types.
- Caution: Verify adapter compatibility for non-cartridge use.
Moonshan 2-300g Liquid Filling Machine
This Moonshan model combines digital control with a peristaltic pump, enabling weight-based, time-based, and price-based operation. It features a hygienic pump that keeps liquid contact to silicone tubing only and can fill bottles up to 300 g. Best for those needing three modes and fast throughput for a range of liquids. A limitation is its larger footprint, which may not fit tight workspaces without layout adjustments.
- Better for: Automated, multi-mode filling with versatile liquids.
- Why selected: Three operation modes and hygienic peristaltic pumping.
- Caution: Requires space planning due to size.
CSY-3200 Weighing Diaphragm Pump Filler
The CSY-3200 model provides a wide filling range from 10 to 3000 g, with a 1 g division value. It supports bottles up to 32 cm tall and can handle flow up to 3.5 L/min. It’s a solid choice for customers needing high accuracy and a robust filling range for heavier liquids. Best for larger bottles and high-precision weighing. A caveat is that diaphragm systems may require more maintenance to keep seals clean.
- Choose this if: You need very wide weight range and precision.
- Why selected: High accuracy and broad compatibility with heavy liquids.
- Caution: Regular diaphragm maintenance is recommended.
Hanchen Peristaltic Liquid Filler
The Hanchen filler uses a two-nozzle peristaltic pump with high accuracy (±1%), making it ideal for small-bottle bottling under 5 oz. It emphasizes hygiene by keeping only the tubing in contact with the liquid, and its design allows easy cleaning and tubing replacement. Best for small-bottle cosmetics or fragrance lines. A limitation is that viscous liquids may not be suitable, requiring liquid viscosity checks before use.
- Best for: Small-batch bottling of thin liquids with high accuracy.
- Why selected: Peristaltic pump minimizes contamination and simplifies cleaning.
- Caution: Not ideal for viscous formulations.
Moonshan 6 Head Liquid Filling Machine
This six-head Moonshan model is built for higher throughput, with six independent channels and a diaphragm pump. It’s designed for thin liquids such as juice or essential oils, with repeat accuracy better than ±1%. Best for mid- to large-scale operations that fill multiple products simultaneously. A caution is ensuring product compatibility with six simultaneous channels in your facility layout.
- Best for: High-throughput environments with multiple product lines.
- Why selected: Independent channels prevent cross-talk between products.
- Caution: Requires adequate bench space and channel management.
Buying Guide: Key Purchase Considerations
What capacity and throughput do you need?
Choose 50 ml models for medium to high-volume fills or multi-head machines for very high throughput. If you fill many small bottles, dosing precision and speed matter most.
What dosing accuracy is required?
Look for 1–5 ml increments with a clear dial or digital control. Peristaltic pumps provide hygiene advantages, while diaphragm systems offer strong accuracy over larger ranges.
How important is oil protection and heating?
Heated syringes or heat pads help viscous oils flow smoothly. An annular heat barrel design minimizes direct contact between heat sources and oil, reducing burn risk.
What are space and setup considerations?
Portable handheld units fit tight spaces, while six-head machines require more bench area. Ensure your work area accommodates the machine’s footprint and required clearance for loading and cleaning.
What maintenance is involved?
Regular cleaning of tubing and heating elements is essential, especially with viscous or particulate oils. Replacement parts like needles, tubing, and seals should be readily available.
What’s the best value strategy?
Balance upfront cost with ongoing efficiency. A higher-capacity or multi-head system saves time on large runs, while a compact gun or handheld model reduces upfront investment for beginners or occasional users.
