This micro-moulding process uses ultrasonic waves, instead of a screw and a heated barrel, to melt the plastic material before it is injected into the mould. The ultrasonic waves lower the viscosity of the melted polymer which then fills thinner geometries with a much lower injection pressure. The machine heats only the amount of plastic needed for each mould cycle so you can mould small quantities, or change the material, with little material waste.
It is used to mould components for hearing aids, implantable devices, and other micro-mechanical systems.
The process can reduce energy consumption up to 90 percent compared with standard injection moulding. The maximum shot size is under two grams.
Use the process to quickly test different materials with low-cost tools during product development.
You get the small moulded sample seen on the picture.
All samples come with a laminated information card.
