    5.What Parts Constitute Ampoule Filling and Sealing Machine?

    The parts in the ampoule filling and sealing machine make it a specialized unit. To bring about precise injection, each component in this handy unit has an important contribution. Here is a list of parts constituted in the ampoule filling and sealing machine.

    Parts Constitute Ampoule Filling

    Parts of Ampoule Filling and Sealing Machine

    Safety Glass

    To safely monitor the progress of the ampoule filling and sealing process, a glass safety door is utilized. This door is a safety feature that decreases the exposure of the operator to the machine while the latter is filling and sealing.

    Ampoule Entrance

    The ampoules are loaded at the machine entrance by the operator or by the ampoule-feeding machine. Then conveyor systems carry them towards the filling station.

    Filling Unit

    It is the main area where ampoules are loaded with different types of injectable solutions. The filling unit consists of catheters and different types of pumps. The pump system aids in the circulation and fluidity of different therapeutic preparations.

    Catheter

    It is a fine needle-like component and its job is to feed the liquid preparation into the ampule. Its main goal is to dispense precise dosing solutions without causing wastage.

    Sealing Unit

    This zone has a burner that radiates flame to melt and soften the ampoule structure. This burner is called a brushed fire head and is responsible for hermetically sealing the ampoule. The molten glass is joined at the sealing station to create a proper sealing structure of ampoules. Different types of regulators are also present in the sealing station that control the placement and temperature of the brush fire head.

    Stand

    This forms the base of the ampoule filling and sealing machine. It is responsible for providing the stability to the machine.

    Touch Screen

    It is a high-tech gadget that has clearly labeled options for programming the machine. Monitoring, supervision, diagnosis, and troubleshooting of the machine are carried out by a sensitive and intuitive touch screen.

    Finished Product Outlet

    The steady motion of conveyors aids in transporting filled and sealed ampoules outside of the machine via the finished product outlet. These products are transferred to the collection bin and then moved to further processing steps.

    6.What are the Filling Methods in Ampoule Filling and Sealing Machine?

    The ampoule filling and sealing machine uses different filling methods to fulfill the liquid filling demands of different industries. Here are the basic filling methods employed by the ampoule filling and sealing machine.

    Vacuum Filling This type of filling is done in a closed system and utilizes the vacuum for drawing liquids in the ampoules. There is no contamination in vacuum filling. Moreover, it results in precise filling.
    Pressure Filling It uses pressure forces to draw the injectable into the ampoules. It is fast and is used for loading high-viscosity liquids.
    Volumetric Filling This kind of filling is vastly utilized for filling ampoules. It loads a pre-measured quantity of liquids. The pump and piston are used in volumetric filling.

    7.Enlist Sealing Methods for the Ampoule Filling and Sealing Machine.

    There are two main sealing methods in the ampoule filling and sealing machine. These sealing approaches are detailed one by one below:

    Pull Sealing Approach

    Pull Sealing Approach

    The melting and sealing process occurs in the middle of the glass ampoule by the intense flame. In this sealing method, the elongation of a thin layer of glass ensues to create a strong seal, thus the name “pull sealing method”. This creates a thin neck of glass ampoules and a pointed seal.  However, there are differences in the height of the glass ampoule by this sealing method. Moreover, the irregular-shaped neck of ampoules causes an increased chance of cutting.

    Tip Sealing Approach
