In the pharmaceutical and nutraceutical industries, capsule moulds play a pivotal role in the production of capsules. As a leading capsule moulds supplier, we understand the diverse needs of our clients and offer a wide range of capsule moulds tailored to different applications. This blog post aims to explore the different types of capsule moulds, their features, and applications.
1. Hard Gelatin Capsule Moulds
Hard gelatin capsules are one of the most commonly used types of capsules in the pharmaceutical and nutraceutical industries. They are made from gelatin, a protein derived from animal collagen. Hard gelatin capsule moulds are designed to produce two-piece capsules, consisting of a body and a cap.
Features
- Precision Engineering: Hard gelatin capsule moulds are precision-engineered to ensure consistent capsule size and shape. This is crucial for accurate dosing and easy filling of the capsules.
- High-Quality Materials: These moulds are typically made from high-quality materials such as stainless steel or brass, which offer excellent durability and resistance to corrosion.
- Customizable: Hard gelatin capsule moulds can be customized to meet specific production requirements, including capsule size, shape, and printing options.
Applications
- Pharmaceuticals: Hard gelatin capsules are widely used in the pharmaceutical industry for the encapsulation of solid and semi-solid dosage forms, such as powders, granules, and pellets.
- Nutraceuticals: They are also commonly used in the nutraceutical industry for the encapsulation of vitamins, minerals, and other dietary supplements.

2. Vegetative Capsule Moulds
With the increasing demand for vegetarian and vegan products, vegetative capsules have gained popularity in recent years. Vegetative capsule moulds are used to produce capsules made from plant-based materials, such as hydroxypropyl methylcellulose (HPMC) or pullulan.
Features
- Vegetarian and Vegan-Friendly: Vegetative capsule moulds allow for the production of capsules that are suitable for vegetarians and vegans, making them a popular choice in the health food and supplement industries.
- Good Barrier Properties: These capsules offer good barrier properties against moisture, oxygen, and light, which helps to protect the contents of the capsule from degradation.
- Compatibility with a Wide Range of Fillers: Vegetative capsules can be filled with a wide range of fillers, including powders, granules, and liquids.
Applications
- Health Food and Supplements: Vegetative capsules are commonly used in the health food and supplement industries for the encapsulation of natural ingredients, such as herbs, botanicals, and probiotics.
- Cosmetics and Personal Care: They are also used in the cosmetics and personal care industries for the encapsulation of active ingredients, such as vitamins, antioxidants, and essential oils.

3. Soft Gelatin Capsule Moulds
Soft gelatin capsules are another type of capsule commonly used in the pharmaceutical and nutraceutical industries. They are made from a gelatin-based shell that is filled with a liquid or semi-liquid formulation.
Features
- Sealed and Tamper-Evident: Soft gelatin capsules are sealed during the manufacturing process, providing a tamper-evident package that helps to ensure the integrity of the product.
- Enhanced Bioavailability: The liquid or semi-liquid formulation in soft gelatin capsules can enhance the bioavailability of the active ingredients, making them more effective.
- Customizable Appearance: Soft gelatin capsules can be customized in terms of size, shape, color, and printing, allowing for brand differentiation and product identification.
Applications
- Pharmaceuticals: Soft gelatin capsules are widely used in the pharmaceutical industry for the encapsulation of drugs, especially those with poor solubility or stability.
- Nutraceuticals: They are also commonly used in the nutraceutical industry for the encapsulation of omega-3 fatty acids, vitamins, and other dietary supplements.
4. Gelatin Capsule Pin Bars
Gelatin capsule pin bars are an essential component of the capsule manufacturing process. They are used to form the gelatin film that is used to make the capsules.
Features
- Precision Design: Gelatin capsule pin bars are designed with precision to ensure the uniform formation of the gelatin film. This is crucial for the production of high-quality capsules.
- Material Selection: The pin bars are typically made from materials that are compatible with gelatin, such as stainless steel or brass, to prevent contamination and ensure the quality of the capsules.
- Easy to Clean and Maintain: Gelatin capsule pin bars are designed to be easy to clean and maintain, which helps to ensure the long-term performance of the equipment.
Applications
- Capsule Manufacturing: Gelatin capsule pin bars are used in the manufacturing of all types of gelatin capsules, including hard gelatin capsules and soft gelatin capsules.

5. Considerations When Choosing Capsule Moulds
When choosing capsule moulds for your production needs, there are several factors to consider:
Production Volume
- If you have a high production volume, you may need to invest in high-speed capsule moulds that can produce a large number of capsules per minute.
- For low-volume production, manual or semi-automatic capsule moulds may be more suitable.
Capsule Size and Shape
- Different applications may require different capsule sizes and shapes. Make sure to choose capsule moulds that can produce the desired size and shape of capsules.
Compatibility with Fillers
- Consider the type of fillers you will be using in the capsules. Some capsule materials may be more compatible with certain fillers than others.
Quality and Durability
- Look for capsule moulds that are made from high-quality materials and are built to last. This will help to ensure the long-term performance of the equipment and the quality of the capsules.
