One-Shot® A Pillar Bicolor

Why is this methodology so revolutionary?


the components are made in two moulds, with two machines, one of 100 tons and the other of 300 tons and two operators in charge of the presses. Another man takes care of joining the two pieces, through the ultrasonic welding machine.


this part of the traditional process is still manual and affects component costs and lead times.


the coupling of the components takes place mechanically: produced separately, they are then placed one on top of the other.


this could cause coupling problems during assembly and small aesthetic imperfections, which may be visible to the outside eye.


it is necessary to superimpose the two components and create pegs which are then dissolved.


The monolithic piece turns out to be very heavy. It is a procedure that creates a component that is not aligned with the Horizon 2020 standards.

Thus was born the revolutionary One-Shot® process!

Summing up

Traditional method

  • Using 2 presses
  • Use of mold + ultra sound welding machine
