Embodiment Construction

[0025] In the following when using directional terms such as up or down relative to the pulp mold, the molding surface of the pulp mold is considered the top and the bottom plate is considered the bottom.

[0026] figure 1 Is a schematic diagram of a manufacturing process for producing molded fiber products, showing a forming section 1 for forming pulp molded articles, a drying section 2 for drying pulp molded articles, and for subjecting dried pulp molded articles to after Post-processing stage 3 of the processing steps, such as lamination, edge trimming of pulp products, packaging of pulp products and the like. The forming section 1 comprises a plurality of rotatable cages 4 each having two oppositely positioned tool carriers 5 . The holders 4 alternately have pulp dies 20 or punches 10 mounted on the tool carriage 5, e.g. if the first holder has a punch, the second holder has a die, and the third holder is a punch mold etc. The tool carriage 5 can be pushed out or pulled...

Abstract

Pulp mould, comprising a porous sintered body (11) having an outer surface (13) and an inner surface (12) wherein a limited area (14) of said inner surface (12) is machined providing a machined surface (14), surrounding an unmachined portion of said inner surface (12).

Description

technical field Background technique [0001] Packaging from molded pulp is used in a wide variety of fields and provides a biodegradable and environmentally friendly packaging solution. Products formed from molded pulp are commonly used as protective packaging for consumer goods such as cellular telephones, computer equipment, DVD players, and other consumer electronics and other products that require packaging protection. Furthermore molded pulp products can be used in the food industry, such as hamburger shells, cups for liquid contents, dinner plates and the like. In addition, molded pulp products can be used to form the structural core of lightweight multi-ply panels or other lightweight load-bearing structures. These products are often complex in shape and in many cases their expected time on the market is short. In addition, the size of this product range can be relatively small, so the advantage is that the production cost of the pulp mold is low, and the mold can be...
