High Precision Plastic Micro-injection Molding Machine for Production of Miniaturized Parts

A first bottom-up high precision plastic micro-injection molding machine which helps the miniaturization of products and producing high precision micro plastic parts such as micro bio-mechanisms, micro-pumps, micro nozzle, medical parts, micro lenses and optical connectors. Other machines only attempt to reduce the size of conventional designs while our machine adopts a revolutionary upward injection design eliminating the air entrapment problem and the need for shutoff valves that restricts melt flow. There are four servos each at the four corners of the mold clamping to automatically adjust clamping pressure for minimum mold distortion. Two linear motors are used to propel the plastic into the mold giving unmatched acceleration and precision well below milligram level. The precision is further enhanced by real-time pressure signature analysis to account for any variations. The mechanical design is simple with mechatronic control for future performance optimization through software upgrades.
