Some capsules are easily confused because of the manufacturing process. Two-color capsules can be made of two-color shells for easy identification.
At present, many capsules are produced in large quantities. Careful observation shows that the capsule is a large caliber and a small caliber. Some manufacturers are powerful and can fully mechanize production. In the case of high production safety factor, monochrome capsules can be made. However, in order to ensure production, most manufacturers use capsules with different colors, which is also used to distinguish two parts with different calibers, so as to avoid mistakes in mass production, leading to high-speed assembly line failure and wasting a lot of raw materials.
The transparent shell capsule is to let users know whether the capsule contains particles or powder, which is convenient for use. In addition, some capsules have changes in internal particles or powder after deterioration, which is also to remind users whether the capsules are safe and normal.
All transparent capsules do exist and can be produced at one time, but as just said, the original monochrome capsules may reduce the production safety factor, and if transparent capsules are used, it is more difficult to identify and greatly reduce the production safety factor.
