Injection molding machine Micro Tech
Designed for the Cleanroom
A small injection molding machine with the designation Micro Tech has been developed by hw.tech GmbH, Gottmadingen, Germany, and Paramecc GbR, Bahlingen, Germany, specifically for production of medical devices. The predecessor was the Micro Plus small electric injection molding machine, which was also developed jointly and presented by hw.tech for the first time at the Fakuma 2006.
The machine targets the microinjection molding market, a field where exact screw recovery and injection of extremely small amounts of melt is essential. Since the Micro Tech has been designed for cleanroom operation, all machine movements are generated with the aid of ball screws and servomotors. Instead of a toggle, a powerful torque motor is used for mold clamping. The machine is claimed to have extremely high part precision. Simultaneous operation along several axes assures short process times. The machine is available with clamping forces of 60 and 100 kN, with a screw diameter of 12 or 14 mm. The machine generates a maximum injection pressure of 2,400 bar and achieves injection velocities of up to 300 mm/s.
