The reduced viscosity that ultrasonic melting induces in all plastic materials means that the Sonorus 1G micro molding machine uses much lower molding pressures than alternative micro molding technologies.
The inability to reduce viscosity in melted material, and the fact that traditional micro molding machines are variations of larger scale macro injection molding machines, means that they use disproportionately high injection pressures and molding pressures. Not only does this lead to significant material degradation, but it also limits the use of these technologies for the manufacture of complex and intricate plastic parts.
The Ultrasion Sonorus 1G uses molding pressures of about 300-400 bar compared with the usual pressure of 1500-2000 bar in traditional micro molding technologies. This means that extremely delicate core pins and intricate core pin configurations can be used, and are not destroyed by high molding pressures.
In addition, low molding pressures make the Ultasion Sonorus 1G very well suited to delicate overmoulding applications.
