Abstract

1430479 Moulding composite trim members MATEC HOLDING SA 27 April 1973 [28 April 1972] 20267/73 Heading B5A The invention relates to a method of making a composite trim member, e.g. for a vehicle body, the trim member comprising a visible skin 3 of plastics material, first and second subjacent layers 12, 14 also of plastics material and at least one substantially rigid portion 13. The drawing shows a production line for the trim members comprising at station A an oven 1 for heating the mould part 2, and at station B a pivotable support 4 and an electrostatic spraygun 5 for spraying dry blend powder to form the skin 3. At station C the powder is melted on the mould and at station C1 a hand impermeable vibration damping layer 14 is deposited from a hopper 15. At station C2 the layer 14 solidifies. A cooling station D is provided with sprinklers 6 for a liquid which may contain a binding agent. Station E comprises an injection mould 2, 11 and an injection head 7 supplied from a polyol reservoir 8, a polyisocyanate reservoir 9 and a reservoir 10 for accelerator catalyst containing a foaming agent. Mould member 11 carries a load bearing wall 13 of moulded felt with inserts 13a. The moulded article is removed from the mould at a station F, the mould members 2, 11 being returned to stations A and E respectively. In a modification, instead of injecting the moulding material, it may be placed directly on the layer 14 and the mould part 11 placed in position before foaming commences. The foam layer 12 may be of sound absorbing material.
