Our liquid capsule filling machines are designed for filling oils, herbal extracts, suspensions, and other liquid formulations into hard gelatin or vegetarian (HPMC) capsules. These machines are ideal for manufacturers of pharmaceuticals, nutraceuticals, dietary supplements, herbal products, and other liquid-filled capsule applications.
We offer a full range of liquid capsule filling systems — from research-scale models to high-output production lines — to meet different production capacities and formulation requirements.
A liquid capsule filling machine is a specialized device used to accurately fill empty hard capsules with liquid or semi-liquid formulations. Compared with traditional powder/ granule capsule filling machines, liquid capsule fillers require more precise dosing systems, reliable sealing/banding mechanisms, and careful handling of capsule materials to prevent leakage and ensure long-term stability.
Liquid-filled capsules are increasingly popular for:
Oil-based supplements (e.g. fish oil, herbal oil extracts)
Fat-soluble vitamins or actives
Herbal extract suspensions / emulsions / tinctures
High-potency formulations with better bioavailability
Any formulation where powder encapsulation is unsuitable
Compared to softgel capsules, liquid hard capsules — produced by a liquid capsule filling + sealing line — offer a cost-effective, efficient, and flexible alternative.
Our machines adopt advanced dosing systems (ceramic pumps, peristaltic or positive-displacement pumps) to ensure precise and consistent filling — with typical dosing accuracy within ±2–3%.
Fully supports both gelatin and HPMC hard capsules, giving flexibility depending on customer demand or formulation requirements.
Designed to handle a wide range of liquids — from low-viscosity oils to suspensions and emulsions — making it ideal for nutraceuticals, herbal extracts, vitamins, and other specialized products.
For liquid-filled capsules, sealing is crucial. We offer full filling + sealing / banding line solutions to ensure capsule integrity — preventing leakage during storage, transport, and use. jspharma.net+1
Whether you need small-batch runs for R&D or pilot production, or large-scale industrial output, our product range covers various capacities to meet different business scales.
Ideal for small-scale production, R&D labs, or product development. Compact size, flexible adjustment, and easy to operate.
For large-scale nutraceutical or pharmaceutical production. Includes integrated filling, sealing/banding, drying, inspection, and capsule output.
For special requirements (e.g. high-viscosity oils, emulsions, suspensions, dual-fill formulations, special capsule sizes/materials), we offer customized filling and sealing configurations tailored to client needs.
Our liquid capsule filling machines are widely used in:
Nutraceutical & dietary supplement manufacturing (e.g. fish oil, herbal oil, vitamin formulations)
Herbal & botanical extract encapsulation
Pharmaceutical liquid formulations (e.g. oily medicines, suspension-based dosage)
OEM/ODM supplement production for global brands
Pilot production, R&D labs, contract manufacturers
Production Volume & Output Demand — small-batch R&D vs mass production.
Liquid Formulation & Viscosity — thin oils, suspensions, emulsions — choose suitable pump & sealing system. tech-long.com+1
Capsule Type — gelatin vs HPMC vegetarian capsules.
Sealing / Banding Requirement — for liquid capsules sealing integrity is critical.
Scalability & Customization — whether you need a pilot unit or a full production line.
Q1: What kind of liquids can be filled?
A: Oils, suspensions, emulsions, herbal extracts, fat-soluble actives, and other liquid or semi-liquid formulations — as long as the viscosity is suitable and formulation is compatible with hard capsule materials. tech-long.com+1
Q2: Can the machine handle both gelatin and vegetarian (HPMC) capsules?
A: Yes. Our liquid capsule filling machines are compatible with both types. jspharma.net+1
Q3: How accurate is the liquid filling?
A: With our precision dosing system (ceramic or positive-displacement pump), dosing accuracy can reach ±2–3% under proper parameters. jspharma.net+1
Q4: How is capsule sealing handled to prevent leakage?
A: We provide integrated filling + sealing/banding lines. The sealing system ensures a consistent seal — preventing leaks during storage and transportation. jspharma.net+1
Q5: Is the machine suitable for small-scale production or R&D?
A: Yes — we offer compact laboratory/pilot machines, suitable for small batches, product development, or trial production.
