    Abstract: The present invention relates to a method for manufacturing a cellulose pulp composition for a moldable cellulose fiber based web, said method comprising:a) providing a cellulose pulp composition comprising at least 50 wt% chemical or semi-chemical wood pulp based on dry weight,b) subjecting the cellulose pulp composition provided in step a) to low consistency (LC) refining at a consistency in the range of 1-7 wt% to an SR value in the range of 18-50 as determined by standard ISO 5267-1, c) subjecting the LC-refined cellulose pulp composition obtained in step b) to high consistency (HC) refining at a consistency in the range of 12-40 wt% with a refining energy of at least 150 kWh/t, andd) diluting the HC-refined cellulose pulp composition obtained in step c) to a consistency in the range of 0.1-10 wt%. The invention further relates to a method for manufacturing a moldable cellulose fiber based web and a method for manufacturing a molded cellulose fiber based product.
