Abstract: The invention relates to an injection molding unit for an injection molding machine for processing plastics, comprising an electro-mechanical dosing motor (D) for rotating a worm conveyor (11) during dosing of the plasticizable material, and an electro-mechanical injection motor (E) for the axial movement of the worm conveyor (11) relative to a plasticization unit (10). The injection motor (E) comprises a spindle drive having a spindle (16). The axes of the dosing motor (D) and of the injection motor (E) are aligned with one another. Due to the spindle (16) of the injection motor (E) being rigidly connected to the rotor (12) of the dosing motor (D) and due to the fact that the dosing motor (D) can be blocked by a braking means in a direction of rotation, an alternative compact, energy-saving injection molding unit is created.

Abstract: The method of evaluating an optical defect in a transparent material includes irradiating the material with light to produce scattered light from the defect, rotating the material about a rotation axis passing through the defect, measuring scattered light intensity at a scattering angle (?s) to the rotation axis by means of a detector, determining the dependence of the measured scattered light intensity on rotation angle (?s) around the rotation axis and characterizing size and/or shape of the defect from that dependence. The apparatus for performing the method has a light source, a rotatable holder for the transparent material, a light sensitive receiving device and an imaging optical system for imaging scattered light from the material within a certain angular range on a detector surface of the receiving device.
