Custom Softgel Manufacturing

We specialize in manufacturing nutraceutical formula softgels. Softgels are some of the most popular forms of delivery method for vitamins & supplements. 

Manufacturing Process of Softgels 

Softgel encapsulation is a common practice, as it is very versatile. The process of producing a softgel capsule is comprised of four main stages:

  1. Preparing gelatin
  2. Preparing the fill
  3. Begin encapsulating the fill
  4. Finishing touches on filled softgels

Preparing the Gelatin

Preparing the gelatin capsule is the very first step in the process. To note, this process is not identical to the process of making veggie softgels. But to begin with gelatin softgels, you must get the ingredients for it together. The four main components are:

  1. Gelatin
  2. Plasticizer
  3. Water
  4. Additives for various traits
To begin, a machine will melt a large quantity of gelatin with the other three components. Not only will it melt all the ingredients, but it will allow for the appropriate mixing of all components. The four components are mixed until the blend is going to make a softgel shell that is durable and effective for the intended use. The addition of coloring agents and other additives will make every blend unique for creating the perfect softgel shell. Following the completed mixture of all ingredients, the mixture needs to stay warm, so it maintains the consistency of a liquid. 

Encapsulating Your Formula Inside A Softgel

Specifically, with softgels, the process of encapsulating the formula happens simultaneously as the shell is added to a machine along with the blend. This process all takes place in a room that is temperature-controlled and with a humidity of around 20%. Having optimal conditions for softgel manufacturing is key to producing a high-quality end product. 

The process of creating a finished softgel starts with the blend of gelatin, which is prepared previously. The gelatin blend will be poured onto two drums, which are extremely cold. The drums roll continually, causing the gelatin blend to both solidify and roll off as a solid sheet, but it will be split in half. With both halves now ready, they will be put through a process that will cut each half to the appropriate size and shape. The two matching halves will be met together, but first, your custom blend will be inserted into a heated wedge. This heated wedge will be encased by both halves of the softgel. Once the wedge is in place, and the softgel is nearly closed, the wedge will inject the custom formula into the softgel. This being the final step of the process, the wedge is removed, and the softgel is quickly sealed or coated as directed and will be set aside to cool and settle. 

Drying & Finishing Process

The softgels will  be put into a cool drum, which will rotate fast to help the gelatin congeal. The finished softgel will undergo further drying, which is a process that is comprised of a couple of steps: 

  1.  Tumble drying
  2.  Drying tunnel
A tumble dryer is a machine that will dry the softgels for no more than 45 minutes. The outcome from this step is going to be the removal of nearly 25% of water within the softgel capsules. 
After being in the tumbler machine, the softgels are introduced to the drying tunnel. This is an environment where the softgels are laid on racks, and subject to swift flow of air continually flows for up to 48 hours. This is the final drying step for the softgel capsules before inspection.
