Liquid Capsule Filling And Sealing Machine Common Questions
Do you have questions about our fully automatic liquid capsule filling and sealing machine? Find the answers below.
A liquid capsule filling and sealing machine is used to fill hard or soft capsules with liquid formulations and then seal them to prevent leakage and ensure product integrity.
The machine opens empty capsules, fills them with liquid using precision pumps, and then seals the capsule edges with a banding or ultrasonic sealing mechanism for leak-proof closure.
Yes, most liquid capsule machines can handle a wide range of liquid viscosities, including oil-based substances like fish oil and CBD, as well as some water-based extracts.
These machines usually support capsule sizes 00 to 5, with adjustable dosing mechanisms to match different capsule volumes and liquid thickness.
Sealing methods include gelatin band sealing, ultrasonic sealing, and thermal sealing, depending on the machine model and capsule material.
Sealing prevents leaks, extends shelf life, and ensures consistent dosing, especially for temperature-sensitive or volatile liquid ingredients.
High-precision models offer filling accuracy within ±1% to ±2%, ensuring pharmaceutical-grade consistency and minimizing waste.
Yes, most machines are built to meet GMP, FDA, and CE standards, using stainless steel construction and hygienic design for pharmaceutical applications.
Production rates range from 1,000 to over 15,000 capsules per hour, depending on the machine type (semi-automatic or fully automatic) and product viscosity.
You can purchase high-quality machines from specialized manufacturers like Yundu Filling Machine, which offers customized solutions and after-sales support.
Products like essential oils, herbal extracts, omega-3 fish oils, and fat-soluble vitamins (A, D, E, K) are ideal for encapsulation in liquid form due to their absorption and stability needs.
Yes, liquid filling typically requires hard gelatin or HPMC capsules with heat resistance and compatibility for sealing. Softgel machines are used for soft capsules.
Softgel machines form and fill capsules from gelatin sheets, while hard capsule machines fill pre-formed empty capsules and then seal them—ideal for smaller batch flexibility and lower costs.
Yes, fully automatic machines can open, fill, seal, and eject capsules in one continuous process, reducing labor and increasing production efficiency.
Regular cleaning, pump calibration, and sealing module checks are essential. Machines should be cleaned after each batch to meet GMP hygiene standards and avoid cross-contamination.
