Female die adsorption mould is often used in the parts such as automotive instrument panel and door guard plate, and is particularly suitable for occasions with high requirements on product surface process. For example, the IMG-L process in the IMG process uses a female die engraved with a skin pattern to form a skin with a skin pattern in the shape of an interior part on the smooth film in the mould, and then the skin is vacuum adsorbed on the skeleton base material.

[0003] Turnover demoulding is a way of turning the product out of the mould. In turnover demoulding, one half of the mould is stationary, and the other half is provided with a movable template.
