After vacuum absorption of excess water to form a wet embryo, the moisture of the wet embryo is reduced to about 40% by natural drying or through a special drying channel. After that, the process of shaping and molding is carried out.
Q2: What are the advantages of the dry pressing process of pulp molded tableware?
A2: 1. The dry pressing process of pulp molded tableware consumes less heat energy and reduces energy consumption.
2. Most of pulp molded tableware is pulp products, which can recycle waste paper, with low cost and low price.
3. The thickness of the pulp molded tableware is thick, and the effect of shock and compression is good.
4. When using for packaging electronic products, pulp molded tableware can prevent static electricity.
Q3: What are the disadvantages of the dry pressing process of pulp molded tableware?
A3: 1. Dry pressed products (including semi-dry pressed) have rough surface and poor aesthetics.
2. The wall thickness of dry-pressed products is thicker and takes up a larger volume.
Q4: What are the main product types and application areas of the dry pressing process for pulp molded tableware?
A4: Dry press products are mainly used for lining boxes of low-end electronic products and precision components. Or used in industrial, agricultural and some medical packaging fields such as egg trays, fruit trays, urinals, and kidney-shaped trays.
