Abstract

The invention relates to a production technology of an automobile seat decorative cover. The production technology comprises the steps as follows: a seat decorative cover base material is placed in an electrical heating oven to be heated, wherein the temperature of the upper oven of the electrical heating oven is controlled within 310-330 DEG C, the temperature of the lower oven of the electrical heating oven is controlled within 340-360 DEG C, the heating time is controlled within 90-100 seconds; the heated seat decorative cover base material is laid between an upper die and a lower die of a forming machine, wherein the temperatures of the upper die and the lower die of the forming machine are both controlled within 3-7 DEG C; the forming machine is operated to obtain a semi-finished automobile seat decorative cover, wherein the forming pressure is controlled within 18-20 MPa, and the forming time is controlled within 55-65 seconds; burrs on the edge of the semi-finished automobile seat decorative cover are removed to obtain the finished automobile seat decorative cover. The production technology adopts PP / PET composite material heating and mold cold-press molding and is free from addition of any chemical composition; the production technology produces no poisonous substance in the whole production process and belongs to an environment-friendly technology.
