METHOD OF PRODUCING DOME COVER, DOME COVER AND DOME-LIKE CHAMBER

摘要

FIELD: process engineering.;SUBSTANCE: dome cover 6 is made by moulding comprising the following stages: forming cavity 14 with the shape of dome cover 6 between top die 12 and bottom die 13 of mould 11 furnished with stop channel 16 to feed molten polymer material into position of top die 12 corresponding to zenith section of dome cover 6, and feeding molten polymer material into cavity 14 via stop channel 16. Polymer material fed from central section corresponding to said zenith section 15 flows uniformly toward periphery of cavity 14. Therefore pressure and temperature difference in cavity 14 differs to limit inhomogeneity of moulding dome cover 6. Dome cover is produced in compliance with abode described method. Dome chamber comprises dome cover made as described above and dome chamber arranged inside dome cover.;EFFECT: limiting partial inhomogeneity of moulding, particularly, in stop channel and outlet areas.;6 cl, 10 dwg
