Security seals GST

Production process

Design department

Here experts create unique samples of security seals. Everything starts with a technical sample – a 3D model is developed by specialists taking into account ergonomics and child-proof safety factors. In case of approval of the industrial design, the second stage comes.       

Tool shop

The 3D model is transferred to drawings. For the future security seal, a prototype mold is being developed for production.           

Plastics casting site

In the mold, the initial castings of the product are produced. The form is made taking into account the material from which the product will be made.

Quality control

At the casting stage security seals pass quality control. This helps to avoid possible technical defects.


All components of the seals are assembled into a single product. The finished security seal passes quality control, and serial production of the product begins.

Marking shop

A computer system assigns a unique number to the security seal. It is also possible to place the customer's logo, dashes and other code options to display other desired information.
