摘要
The plastification- and injection device for microinjection molding, comprises plastification cylinder (5) and a snail with volutions. The snail is formed conically thrust snail in conveying direction. The snail is coupled with rotatory drive (4) and linear drive. A piston-spraying device is connected with the plastification cylinder via a melt channel (11). Displacement means are intended for the adjustment of the width DELTA of the gap between the snail outside diameter and the cylinder inside diameter. The plastification- and injection device for microinjection molding, comprises plastification cylinder (5) and a snail with volutions. The snail is formed conically thrust snail in conveying direction. The snail is coupled with rotatory drive (4) and linear drive. A piston-spraying device is connected with the plastification cylinder via a melt channel (11). Displacement means are intended for the adjustment of the width DELTA of the gap between the snail outside diameter and the cylinder inside diameter. On the melt way of the conical snail to the piston-spraying device an intermediate storage is intended for the reception of plastic melt, so that the snail can be continuously operated. A gravimetric metering unit is intended in the device. A section continuously decreases in conveying direction of the outside diameter of snail webs (3) and the diameter of snail core (2) remains constant. An independent claim is included for a method for the production of lesser weft weight for microinjection molding.
