AI Technical Summary
Technical Problem
In existing technologies, the foam is not evenly dispersed in the mold, resulting in slow molding and dehydration, making it difficult to apply to small or complex molded fiber products.
Method used
By employing a porous mold and a vacuum system, the foam is rapidly and uniformly dispersed and water and air are efficiently removed through the sealing of the mold and the rapid supply of foam, thus forming a multi-layer molded fiber product.
Benefits of technology
It enables rapid forming and efficient dehydration of molded fiber products, improving product quality uniformity and precision, and making it suitable for various packaging solutions to replace plastics and aluminum.

Abstract
The invention relates to a method for forming a moulded fibre product. In the method, a layer (10) is formed by a mould pair (11) of a mould (12, 13) from a foam comprising fibres, water, air and a blowing chemical. Furthermore, in the method, the foam is fed between the moulds (12, 13) and the mould pair (11) is closed and opened. The foam is fed via one of the moulds (12, 13) while the mould pair (11) is sealed from its sides. The invention also relates to a moulded fibre product.
