Capsules are a popular form of medication delivery, and the technology used to manufacture them has improved significantly over the years. This article offers an overview of different capsule manufacturing technologies, and how each type of technology can be used to create capsules that are safe, effective, and reliable. It will cover topics such as capsule filling, printing, and coating. As well as discuss the advantages and disadvantages of each technology. Through this article, readers will gain an understanding of the different capsule manufacturing technologies and their capabilities. Which will help them make informed decisions when selecting a technology for their capsule production needs.

Introduction To Capsule Manufacturing

Capsule manufacturer is one of the most popular forms of oral dosage forms and is used to deliver a wide range of active ingredients and excipients. Capsules are available in various sizes and shapes, depending on the application and formulation. The most common types of capsules are hard and soft gel capsules, liquid-filled capsules, and vegetarian or vegan capsules. Capsule manufacturing involves the encapsulation of specific active ingredients, excipients, and fillers within the capsule shell. The process requires specialized machinery and process systems that vary depending on the type of capsule being manufactured.

Processes And Technologies For Gelatin Capsules

Gelatin capsules are made of gelatin, a protein derived from collagen that is extracted from animal sources such as bovine hide, porcine skin, and avian bones. Gelatin capsules are most commonly used to deliver solid dosage forms such as tablets, pellets, and powders. The process of making gelatin capsules involves several steps: first, the gelatin is mixed with water, glycerin, and other ingredients to form a gelatin solution which is then poured into molds. The molds are then dried and heated in an oven to harden the gelatin. The capsules are then filled with the active ingredients and sealed.

Technologies For Liquid Filling Of Capsules

Liquid-filled capsules are used to deliver liquid, semi-solid, and viscous products and can be made from gelatin or non-gelatin materials. Liquid-filled capsules are typically made using a rotary die-filling process. This process involves the application of pressure to the capsule contents to ensure that the liquid is evenly distributed within the capsule. The capsule is then sealed with a heat-sealing process.

Liquid capsule filling technology is a process used to fill capsule shells with liquids, semi-solids, or pastes. The technology is often used to fill nutritional supplements, such as vitamins, minerals, and herbal extracts, in capsules. It is also used to fill pharmaceutical drugs, medical devices, and other products into capsules.

The process of liquid capsule filling starts with the selection of a liquid or semi-solid material, such as oil, gel, or paste, which is then dispensed into a pre-formed capsule shell. This dispensed material is then sealed and compressed into the desired shape and size, ensuring that the capsule is properly filled.

Vegetarian And Vegan Capsule Manufacturing

Vegetarian and vegan capsules are increasingly popular due to their sustainability, lack of animal byproducts, and vegetarian-friendly ingredients. Capsules are typically made from plant-based materials such as pullulan and hypromellose. The process of making vegetarian and vegan capsules involves the mixing of plant-based materials with water and other ingredients to form a dough-like consistency. The dough is then fed into a die-filling machine, which forms the capsules and seals them.

Production Capacity And Scalability

Capsule manufacturing is a highly scalable process and can easily be scaled up or down to meet changing production requirements. The production capacity of capsule manufacturing depends on the type of capsule being produced. The size and shape of the capsule, and the type of machinery and process systems being used. For example, the production capacity of gelatin capsule manufacturing can range from 1,000 capsules per hour to several million capsules per hour. While the production capacity of liquid-filled capsules can range from 500 capsules per hour to 1,200 capsules per hour.

Cost Considerations For Capsule Manufacturing

The cost of capsule manufacturing is largely dependent on the type of capsule being produced and the type of machinery and process systems being used. The cost of capsule manufacturing is also affected by the cost of raw materials, the cost of labor, and the cost of energy, and utilities. Additionally, the cost of capsule manufacturing can be affected by the size and shape of the capsule. The type of packaging, and the complexity of the process.

When it comes to capsule manufacturing, cost considerations are of utmost importance. The cost of the manufacturing process will ultimately determine the cost of the finished product. So it is important to understand the various costs associated with capsule manufacturing. The most important cost consideration is the type of equipment used to create the capsules. Depending on the capsule size and formulation, some equipment may be more cost-effective than others. For example, if a customer needs a small batch of capsules. It may be more cost-effective to use a manual capsule-filling machine than a high-speed, automated one.


Capsule manufacturing technologies are an important part of the pharmaceutical industry. Different technologies are available, each with its own advantages and disadvantages. The choice of the most appropriate technology for any particular application will depend on a variety of factors. Such as the capsule size, shape, and material, as well as the desired production rate and quality. Understanding the different capsule manufacturing technologies and their associated benefits and limitations is essential for ensuring the quality of the final product.
