Capsule Filling and Sealing Machine

A capsule filling and sealing machine are used mostly in pharmaceutical industry to be used for production of large number of capsules. Companies that have high volume of production prefer this machine because it has the capability to produce equal sized, same weight and high-quality capsules.

The system is highly automated that no faulty or damage capsule can exit the production setup. It ensures proper filling of material with quality standards.

Suppository Filling and Sealing Machine

One of the latest methods used for drug intake in human body are suppository medicines. These suppository drugs are carried inside the body through rectum, vagina or anus.

A suppository filling and sealing machine fills the material in powder, tablet or liquid form. Cut down in different shapes. Cools the process to a standard temperature and finally seals the suppository medicine that can easily enter human body.

Hard Capsule Liquid Filling and Sealing Machine

Hard capsule liquid filling and sealing machines can easily be used to fill solutions and suspension into hard capsule. Its stepless converter of frequency make its operation easy. Pharmaceutical industry is using this machine on a high scale to produce better health care supplements.

Its human machine interface and automatic process ensure proper filling and sealing of capsule without any compromise on quality. Highly precise pumps and servo motors are used to control the input of material at both upper and lower end.

Vial Filling and Sealing Machine

Around 2000 different types of vial filling and sealing are used around the globe in which pharmaceutical industry itself uses 86% of it. These machines are highly reliable and safe in their processes. Liquids, substances, solids and solutions are filled in these vials and then sealed in a proper way to avoid any contamination.

Vials for oncology and biopharmaceutical industries are the most common used in the whole world. These machines are very efficient that they properly seal the while with heat, rubber or foil so it’s better prevention. Machines these days can give an output of 650 vials per minute which is a huge number when it comes to bulk production.

Soft Gel Capsule Filling and Sealing Machine

An electromechanical machine which fills gelatine shells with liquid, solutions and suspensions. Depending upon the dosage, Softgel capsule filling and sealing machine makes best suppository or oral medicines. Softgel material is entered in system of die, there the solution or substance is injected in it and them finally properly sealing is done.

Industries like pharmaceutical where production capacity is too high, these Softgel encapsulation machines provide much benefit to them.

Pouch Filling and Sealing Machine

Pouch filling and sealing machines are mostly used in food, cosmetic and pharmaceutical industry. Medicines, dugs and other hair products are packed in these pouched and sealed with melting by high temperature.
