FIELD: engines and pumps.
SUBSTANCE: proposed method comprises cutting out circular and lengthwise work pieces from glass fabric impregnated with binding agent. Note here that lengthwise work pieces are arranged inclined to glass fabric warp direction. Split metal insert with skewed inner wall is arranged on mould male die edges to embrace male die spherical part with uniform annular clearance over flange thickness. Flange inner and outer layers are composed of annular work pieces and inner and inner and extra layers on male die. Lengthwise work pieces are laid in said clearance to make butt joint and to overlap joints by the next lengthwise work pieces. Then, produced multilayer pack is subjected to hot moulding.
EFFECT: higher quality.
