    Abstract: A method for preparing cellular plastic particles comprising the steps:



    providing a plastic material in the form of pre-expanded plastic material particles,
    loading of the pre-expanded plastic material particles with a blowing agent under the influence of pressure,
    expanding the pre-expanded plastic material particles loaded with a blowing agent for the production of cellular plastic particles, in particular cellular plastic particles with lower density, under the influence of temperature, wherein the expanding of the plastic material particles loaded with blowing agent under the influence of temperature is carried out by irradiating the plastic material particles loaded with blowing agent with high-energy thermal radiation, in particular infrared radiation.

    Abstract: An apparatus (100), assembly and process for depositing fiber material on a surface (131) is provided herein. The apparatus (100) comprises an material extruder (101) having a clutching mechanism configured to engage a fiber material with a extruder motor that is configured to feed said fiber material into a filament guide. The apparatus (100) further includes a modular layup nozzle (109) comprising a cold end portion (110), hot end portion (116) and output nozzle (108). The cold end portion (110) is configured to receive said fiber material and cool down the temperature thereof by using a coolant before said fiber material enters a hot end portion (116) of the apparatus (100). The hot end portion (116) further comprises a heat block (118) that is configured to convert the fiber material into a molten form and deposit said fiber material into a composite part (131) through a output nozzle (108). The fiber material is then cut by a cutting assembly (103) after a deposit operation is complete.

    Abstract: A method for heating a preform (1) comprising a body portion (4) extending along a longitudinal axis (A1). The method comprises the following steps:—introducing the preform (1) into a heating apparatus (5) comprising an array of infrared emitters (50) arranged in multiple columns (Cj) and rows (Ri); —setting power levels of the infrared emitters (50) so as to divide said array into subsets of columns (SCn); and—heating the preform while translating it in a direction parallel to the rows (Ri), and simultaneously rotating it around its longitudinal axis, the rotation and translation speeds, and the power levels of the infrared emitters (50) being set so that the power levels of the subsets of columns (SCn) facing zones (42) of the body portion extending longitudinally are different from the power levels of the subsets of columns facing the rest of the body portion, said zones extending relative to one another in a polygonal array.
