摘要

Injection moulding of plastic articles with a sheet or leather covering comprises positioning the sheet (7) with its outer surface in contact with one half (1) of mould. Plastic melt (6) is injected into the interior of mould (3) between inner surface of sheet and other mould half (2). Before interior is completely filled with melt, gas (8) under atmospheric pressure is introduced into melt
