softgel capsule structure
A pill capsule is a simple yet highly engineered delivery system. Most capsules consist of two main parts: a body and a cap that fit together to enclose the active ingredients. Some capsules are one-piece softgel capsules designed for oils or liquids, while the more common hard capsules are two-piece and ideal for powders, гранулы, или гранулы.
Capsules can hold powders, бусы, жидкости, or oils, and some are specially coated for enteric or delayed release. Choosing the right type depends on ingredient form, стабильность, and how it will be consumed, which also affects capsule filling and efficiency.
Table 1-Typical capsule Fill Form and Recommended Capsule Type
| Filling Form | Best Capsule Type |
| Пудра | Hard capsule |
| Oil | Мягкие капсулы |
| Sensitive enzymes or probiotics | Enteric capsule, coated vegetarian capsule |
Capsule size affects dose capacity, проглатываемость, and even production considerations like machine compatibility. Для производителей, the right size is not just about volume, powder density and flow behavior are equally important. Here’s a detailed capsule size chart for better understanding.

Choosing the right size ensures smooth capsule filling process and optimal dosage. Low-density powders like herbal extracts or probiotics often require larger capsules, while high-density actives may fit in smaller sizes. Manufacturers should consult their capsule supplier’s exact volume specifications for precise planning.
Capsule shells aren’t just containers—they’re like tiny guardians, protecting the ingredients and controlling how quickly nutrients are released. The shell material affects capsule filling, стабильность, and final product quality. Суммируя, the shell plays both protector and gatekeeper from factory to consumer.
Now, let’s take a look at the different types of capsule shells and how each one plays a unique role in your product’s performance and production process.

Hard gelatin capsules are two-piece shells that hold powders or granules and release them quickly, making them great for multivitamins or powdered supplements. Soft gel capsules are one-piece and flexible, perfect for oils or liquid suspensions like fish oil. They dissolve a bit slower but boost absorption, seal liquids tightly, and mask taste. Hard gel capsules are easier and cheaper to make, while softgel capsule give delicate liquids extra protection.
Table 6-comparison between Powder capsules and Liquid Capsules
| Особенность | Powder-Filled Capsule | Liquid-Filled Capsule |
| Поглощение | Стандартный, depends on dissolution | Often faster for fat-soluble ingredients |
| Сложность производства | Простой | Более сложный, requires specialized equipment |
| Стабильность полки | Stable if moisture-controlled | Sensitive to temperature and oxidation |
| Fill Types | Сухие порошки, гранулы | Масла, эмульсии, liquid suspensions |
| Расходы | Ниже | Выше |
Powder capsules release ingredients steadily and are easy to fill, making them ideal for most vitamins and herbal extracts. Liquid capsules dissolve faster for fat-soluble nutrients like oils and emulsions, but they need special equipment, careful handling, and sealed shells to stay stable.
Once you know which type of capsule fits your product, the next step is bringing it to life on the production line. Making capsules looks easy, but in reality, turning powders and oils into uniform, ready-to-use empty pill capsules takes precision, время, И правильное оборудование. Here’s how the process unfolds in real factories.
Подготовка сырья: Powders or liquids are weighed, blended, and conditioned for smooth flow.
Shell production: Gelatin or HPMC is formed into empty gel capsules through dipping or molding.
Наполнение: Powders are dosed with tamping pins; liquids are injected into softgels.
Запечатывание & banding: Hard gelatin capsules are locked; softgels are sealed.
Сушка & осмотр: Capsules are dried, polished, and inspected for weight, форма, and defects.
Упаковка: Final capsules are packaged into bottles, блистерные карты, или пакетики.
Capsule shell line: Forms empty gelatin or HPMC shells.
Hard capsule filling line: Dosing, трамбовка, sealing stations.
Softgel encapsulator / liquid filler: Handles oils, эмульсии, and liquid blends.
Осмотр & упаковочные машины: Weight check, metal detection, полировка, and bottling.
Shell production: Gelatin or HPMC solution is deposited on pin bars to form uniform capsules.
Conditioning & sizing: Capsules are dried and cut to the right size.
Наполнение: Powders or liquids are metered and deposited.
Запечатывание & полировка: Hard gel capsules are locked; while soft gel capsule are sealed and polished.
Final QC: Capsules are checked for weight, integrity, and appearance before packaging.
Real factories face four main challenges when filling capsules. Knowing them helps you understand why advanced equipment matters.
Filling capsules might seem simple, but powders can be tricky, flowing unevenly or clogging the doser. Too much or too little in each capsule leads to wasted material and failed batches. Поэтому, keeping weight variation around ±3–5% keeps capsule production on track.
Capsules are fragile, and a rough touch can easily damage them. Misaligned caps or too much force during filling can crack shells or cause gelatin softgel capsule to leak. Keeping the right alignment and gentle turret speed helps each capsule stay perfect and ready for use.
Fine powders can clump, bridge dosing holes, or stick to rods, causing underfills and waste. Anti-bridging designs, coated rods, and gentle vibrations keep the powder flowing smoothly.
Powder dust can sneak around the line, creating mess and risking contamination. Enclosed stations, HEPA filters, and gentle airflow keep the dust in check and the production safe.
When it comes to turning tricky powders and delicate shells into perfectly filled capsules, the machine you choose can make all the difference. Право capsule filler machine doesn’t just speed up production, it keeps every dose accurate, every shell intact, and every capsule filling line running smoothly. Let’s see what matters most when picking one capsule making machine.
When evaluating an automatic capsule filling machine, there are several factors that determine whether it will keep your line running smoothly:
Output and speed: How many capsules per hour do you need? Machines vary from small-scale lab units to high-speed production lines capable of tens of thousands per hour. Picking the right capacity ensures your line meets demand without overworking equipment.
Fill accuracy: Precision is everything. Look for machines that consistently meet your target fill weight, typically within ±3-5%, to avoid waste and failed batches.
Capsule compatibility: The machine needs to handle the types you use, whether gelatin, HPMC, or specialty shells, without bending, трещины, or causing jams.
Powder or liquid handling: Мелкие порошки, sticky granules, or liquid oils each pose unique challenges. Machines with anti-bridging mechanisms, rod coatings, or enclosed liquid injection systems help prevent common issues.
Hygiene and dust control: A well-designed enclosure, HEPA filtration, and positive-pressure zones protect both product and operators from airborne dust.
Support and service: Consider warranty, spare parts lead times, and availability of validation support. A machine that comes with strong service backing can save months of headaches.
Джинлу Упаковка designs NJP series capsule filling machines with real-world production challenges in mind, turning common pain points into smooth solutions.
Precision powder handling: Adjustable feeding angles, anti-bridging pneumatic vibration dosing stations, and rods treated with non-polar electronic polishing keep powders moving consistently, preventing underfills and sticking.
Capsule care: Gentle groove air blast pin, servo-controlled tamping, and in-line alignment ensures intact shells without cracks or leaks.
Clean and safe design: Enclosed filling stations, and positive-pressure zones reduce dust and contamination, while integrated design makes cleaning simple.
