Pulp molding equipment are working in a wet and difficult environment, pulp is abrasive. The choice should be guided by three objectives, long life lasting, manufacturing efficiency and the minimum energy consumption.
Stainless steel is a absolute must for all components in contact with pulp, there is no exception to this rules.
Efficiency required tough, simple and excellent mechanical design of the equipment, a user friendly interface with the machinery, and the minimum maintenance work.
Energy consumption is the key to competitiveness, an efficient plant should not exceed a total energy of 3,5 kW per kilo of paper and a “must have” is the recycle of energy and water through an exchange tower.
SPM molders are fully rotary molders to insure the best drainage and an even thickness distribution of pulp on top an sides of the packaging as they are the main cause of warping and uncontrolled shrinkage during the drying process. In order to further improve the surface aspect and moisture content of products SPM molders are equipped with an Wet-Press station.
