    1.What are ointments and how to prepare them?

    Ointments are formulations prepared for application on body usually skin.  Their appearance is “semi-solid” as they have an oily or greasy consistency. Most ointments are usually prepared with substances that act as a drug on the area it is applied to usually skin and/or get absorbed into the blood to act systematically.

    prepare them

    Petroleum jelly is often used in their preparation and hence the greasy nature, and many dyes and aromatic substances are added to make them acceptable for human use.

    The main purpose of using ointments out of all the skin product is to achieve an occlusive effect, which not only drives the medication into the skin more rapidly but also provides more protection against loss of moisture, as they tend to remain on the skin for longer durations than a solution or cream base, since the common ingredients used in the preparation is often mineral oil and petroleum.

    2.What materials are used to make ointment tubes?

    The first collapsible tubes were made of a number of materials including tin, zinc and lead. These tubes were sometimes coated with wax from inside to avoid material adhesion. Now a days you will find aluminum tubes more often used in various industries because of its property as a perfect container.

    perfect container

    As to why aluminum is a perfect container there are certain points. For instance aluminum does not have a leeching effect i.e. it does not contaminate the product by releasing its residues making it safe, it can withstand high fluctuation in temperature thereby increasing shelf life of the product and many more.

    Apart from aluminum, tubes are also made in plastic such as polyethene. Majorly plastic tubes are used in cosmetic and food industries. Unlike aluminum tubes plastic tubes retain their shapes when squeezed with unique decoration that’s appealing to the buyer from marketing and sale point of view.

    3.What is an automatic ointment filling machine?

    You are now aware that ointments are semi-solid dosage forms and these are packed mostly in collapsible tubes. Now the question is how they are packed? Well you can simply weigh and fill the product in an empty tube, use a hand held sealing tool and seal the tube or you can avoid all the laborious work and buy an automatic ointment filling machine.

    Adjustment of machine according to individual tube specification

    tube specification

    Before pressing the debugging button you need to make sure that the cup seat, plate (turning), cooling ring, heating sprayer, code searching and tube pressing hammer, filling nozzle and material cylinder are adjusted according to the length and diameter of the tubes. Here is how you do it.

    1. Place the cup seats with the tubes into the holes of rotary disc. Rotate the pulley manually. Adjust the height by loosening the screws of rotary table and turning the handle of the table. This will make the bottom of the internal blade 3-5mm away from the tail of the tube.
    2. After rotary table adjust the heating ejector pin. For a convenient debugging remove the cooling protection ring. Move the cup seats with tubes to the heating unit by manually rotating the pulley. Loosen the screws of the heating ejector pin to facilitate manual ejection of heating pin. At this point the tail end of the tube will be 3-5mm away from the holes of heating sprayer. Tighten the screws to lock the settings.

    heating sprayer

    1. Adjust the pressure of clamp according to the size of the tube.
    2. Loosen the nuts of ejector pin to raise the ejector pin to a height 10mm higher then the cup seat. Once adjusted tighten the screws.
    3. Now finally you have to adjust filling and lifting ejector pin height, color code and tube feeding.
    4. Turn on the chilling unit by opening cold water valve and start debugging.

    11.What are failure solutions of an ointment filling machine?

    • Material contact and heating holes blocked: It occurs when the tubes are filled with excess material and adherence of the material with the wall of the container. Adjust the air blowing unit and the volume of material according to the capacity of the tube.
    • No tube ejection from cooling ring: This issue can be resolved by adjusting cooling ring, heating temperature and increasing the distance between the tube and the heating unit to more than 5mm.

    Adjusting tubes

    Adjusting tubes- Picture- Courtesy- You Tube

    • Sharp edges at one or both side: Alignthe heating device vertically to the center of the hole of the rotary table. Adjust the volume of cooling water. Reduce the heating temperature and clamp pressure.
    • Color code position is not right: Adjust the position of the tube before adjusting color code unit followed by adjusting the angles of the detector. If the problem not resolved check the height of the tubes.
    • Vertical and horizontal code adjustment: Adjust the light emitted by the detector to avoid overlapping.
    • Transparent tube adjustment: Insert a code searching hammer in to the tube diameter. It will shade the light emitted by the detector.
