manufacture & filling gel

Dipping

Pairs of the stainless-steel pins are DIPPED into the dipping solution to simultaneously form the caps and bodies

Spinning

The pins are ROTATED to distribute the gelatin over the pins uniformly and to avoid the formation of a bead at the capsule ends

Drying

The gelatin is DRIED by a blast of cool air to form a hard shell

Stripping

Series of bronze jaws STRIP the cap and body portions of the capsules form the pins

Trimming

The stripped cap and body portions are TRIMMED to the required length

Joining

The cap and body portion are JOINED and ejected from the machine

Rectification

The empty capsules are oriented on the same direction (i.e. body end downward)

Separation

Separation of caps and bodies

Filling

Dosing of fill material

• Stroking-in/Dribbling-in

• Auger/Spindle dosing

• Tamping/Disc-dosing

• Dosator/Tube-dosing

Replacement of Caps & Ejection of Filled Capsules

The cap and body bushing portions are rejoined. Pins are used to push the filled bodies up into the caps for closure and to push the closed capsules out of the bushings

Sealing

To develop TAMPER-EVIDENT capsules

• Gelatin Banding (sealing with colored band of gelatin)

• Heat Welding (fuses the cap and body to the body through the double wall thickness at their juncture)

• Thermal Coupling (uses a liquid wetting agent)
