Gelatin Softgel Die Roll V.S. Veggie Softgel Dies

With the popularity of vegetable softgel, more and more manufacturers try to make veggie softgel. As we know softgel die roll is one of the most crucial parts of softgel tooling which affect the leakage, filling accuracy, and shape directly. Here Joysun would like to share some differences between dies for gelatin softgel and veggie softgel.

The cavity size (pocket size) differs. To manufacture a same filling amount of softgel, gelatin requires a relatively smaller cavity size while the vegetable softgel needs a bigger pocket to do so. This is because gelatin ribbon has better elasticity, so it can expand bigger to hold more filling oil.

Lip/step design changes. Another difference visible to the naked eye is that we usually use single lip dies for gelatin softgel manufacturing. While in vegetable softgel production, bi-lip and triple-lip are more often used. We also change the cutting edge height and angle to make a better cutting. A good cutting is directly related to a good seam and sealing on softgel.

The utilization efficiency of dies space is not the same. Since cavity/pocket size for vegan softgel is bigger than gelatin softgel, this means in the same limited space(length*diameter), the number of cavities on a vegan die is much less than that of gelatin softgel die. Therefore, the utilization rate of vegan dies is lower. More shell material wastage and higher production cost.

The wedge/segment, guide plate, and gear can only be used again when the user orders exactly the same dies (with the same cavity shape, size, layout). Otherwise, a full set mold should be replaced.

JS provides softgel dies for animal gelatin such as bovine, pigskin, and fish powder; and die rolls for vegetable softgel such as starch, tapioca, carrageenan compounding raw material.
