TET machine molds plastic tube shoulders and heads of tubes and injects them to tube body. All mechanical movements are controlled by a cam disc. All important functions are monitored and regulated by an electronic control system.

The whole machine consists of several component blocks. The main component of the machine is a rotary table with 10 pressing tools. Each of these pressing tools consists of a die head with a pressing die that defines the outer shape of the tube head and the opening of their neck. The inner shape of the tube head is formed by a core.

The rotary table rotates 36 ° per working cycle. Each pressing tool goes through all 10 workstations.
