7 steps of Blood collection tubes Manufacturing Process
- Cap and stopper process
- Labeling process
- Dosing process
- Capping process
- Centrifuge process
- Shrink packaging process
- Final Packaging process
Cap and stopper Combination
The 1st step in blood collection tube manufacturing process is combining rubber stopper cap and the plastic stopper cap using cap combination machine.
There are two ways of cap combination in production lines. One is up-press cap, the other one is push-down cap showing in the picture.

Labeling
2nd step in the production line step is labelling. Using a labelling machine can efficiently apply stickers or labels on the products like containers, tubes, bottles and etc.

Dosing
Using an automated system to feed the equipment with the products which contain liquid.
Capping
Using capping machines to apply caps on the tubes.
Centrifuge
Using centrifuge machines to cause denser substances and particles to move outwards in a radial position. This can help additives spread on the tube evenly. ( See video above)
Shrink Packaging
Using a heated air system to shrink a tray of blood collection tubes. Sometimes, we will use Aluminum plastic packaging to well protect the tubes.

Final Packaging
Carton packaging and storage.
