The first Freeformer to be delivered to an Asian processor is currently operational at Singapore's Tempco Manufacturing. The company is already a major user of Arburg molding machinery, including thermoplastic and thermoset injection molding machines, micro-injection molding machines, and bulk molding compound (BMC) compression molding machines. Tempco is using its Freeformer to form sample parts.
Furthermore, Tempco, a leading molder of electrical and electronic compounds, will take delivery of its 100th Arburg machine in October according to David Chan, David Chan, Managing Director of Arburg Singapore and responsible for the entire ASEAN region.
With Arburg Plastic Freeforming, the standard granulate is initially melted in a plasticizing cylinder similarly to injection molding. A stationary discharge unit with a special nozzle then applies tiny plastic droplets layer-by-layer onto the part carrier using high-frequency piezo technology at a specified duty cycle of 60 to 200 Hertz. Depending on the nozzle used, the diameter of the droplets generated under pressure is between 0.2 and 0.3 millimeters.
