Pinjection is a manufacturing company producing needle-based injection systems (NIS).

Various parts are produced by either plastic injection molding or metal forming and after passing several quality control steps they are assembled into pens. The pens are sent out to pharmaceutical companies so that the medicine cartridge is inserted and ready-to-use pens are packaged to be shipped to the pharmacy.

Pens are produced in different color codes identifying the installed medicine as required by the pharmaceutical company. The color codes are easily identified by the patients.

Most of our products are used to deliver different types of insulin products. However, pens are also used to inject a wider range of biotech products ranging from growth hormones to supplements. 

We deliver pens in three individual packages as follows:

  1. The “Dosing Mechanism” – involves more than 10 smaller parts that smoothly and precisely apply the required displacement. 
  2. The “Cartridge holder” – contains and covers the prefilled glass cartridge and includes standard threads to install the needle.
  3. The “Pen Cap” – protects the cartridge holder and matches the dosing mechanism color code.
