It is mainly used in medical, chemical packaging and other industries. Different industries have different requirements for pharmaceutical aluminum plastic composite cover.
More understanding of the pharmaceutical aluminum plastic composite lid, today we will look at how to judge the quality of the aluminum plastic composite cover by appearance?
1. Check the riveting point. The size of the riveting point is the same, and the table should be smooth, uniform thickness, no rough edges, and the color is consistent with the color of the plastic cover.
The diameter of the riveting point should be 1-1.5mm larger than the diameter of the aluminum cover riveting hole (the side side length of the flanging side of the aluminum plastic composite cover is 1-1.5mm).
The automatic molding machine can meet all the above requirements, and the manual riveting will appear on the table with uneven surface, round and round, and drawing.
Hair edge and other phenomena, especially using manual electric heating tools for riveting, the temperature can not be controlled, cause the riveting materials to be heated uneven, change color, even.
I'm going to have a focal point.
2. Check the clearance. Check the gap between the plastic cover and the aluminum cover, and the bottle cap with the mechanical equipment is the pressure formed by the heating side, the plastic cover and the aluminum cover.
The hand riveting can't add pressure, so the gap between the aluminum cover and the plastic cover is large and can be moved up and down.
3. Check whether the aluminum cover is deformed, whether the edges of the aluminum cover are neat, whether the aluminum cover height conforms to the packaging requirements and the table and oxidation treatment (or film processing).
). The roundness of the aluminum cover directly affects the normal work of the sealing machine. The clearance between the inner diameter of the aluminum cover and the outer diameter of the bottle mouth should not be too large, otherwise the seal will be sealed.
There will be wrinkles.
4. Check whether the aluminum cover is open after opening of the medical aluminum plastic composite cover, and whether it is flat. Check the breakpoint burr after opening of the breakpoint medical aluminum plastic composite cover.
Whether it is too large or not, should not feel. Check whether there is burr or unbroken place after opening of the carved medical aluminum plastic composite cover, and the mark should not be turned up, no row.
The hand feeling.
5. The aluminum cover must be made of aluminum alloy, and the thickness of aluminum is also the important reason for the direct impact on the strength of the aluminum cover.
The thickness of the material varies with the change of the outer diameter. The average diameter is 13--20mm aluminum cover, and the thickness of the aluminum is within 0.18--0.2 LMM range. 28 --
Aluminum cover of 33mm, aluminum thickness of 0.23--0.25mm range of choice.
At home, there are some small cottage enterprises that do not have the production conditions, neither automatic equipment nor clean environment, and aluminum cover is not cleaned and used.
Manually combine the aluminum cover and the plastic cover, and then use the electric soldering iron or simply; The tool is hot riveting some of the raw material manufacturers even directly with the pharmaceutical preparations.
Contact with rubber plugs, also by manual assembly (such as oral liquid preparations in the domestic general use of the status of manually assembled rubber plugs) is not consistent with GMP.
Standard. If carefully checked according to a, b and c, it is possible to distinguish mechanical riveting and hand-riveted medical aluminum plastic composite cover.
In the case of possible, the pharmaceutical factory should master the production process condition of the pharmaceutical aluminum plastic composite cover, so as to ensure the quality of the purchase.
