The pulp molding hot press, also known as the pulp molding shaping machine, is a core post-processing equipment in the pulp molding production line. It utilizes precise high-temperature and high-pressure technology to perform secondary shaping on dried pulp molding products, effectively correcting deformation caused during the drying process while optimizing the surface smoothness of the products. This not only enhances the aesthetic appeal of pulp molding products but also significantly boosts their market competitiveness.
In the pulp molding production process, after wet pulp blanks undergo drying (either by oven or air-drying), they tend to experience varying degrees of shape deformation (such as edge warping and dimensional deviations) due to moisture evaporation and fiber shrinkage. Additionally, the product surface is prone to wrinkles, which directly affect the usability and appearance quality of pulp molding products.
To address this, professional shaping treatment using a pulp molding hot press is required after drying: Place the pulp molding products to be processed accurately into customized pulp molding molds. Once the machine is activated, under the combined action of high temperature (100℃-250℃) and high pressure (10-20 MN), the products undergo hot-press shaping. The end result is qualified pulp molding products with regular shapes, precise dimensions, and smooth surfaces.
For the wet pressing process (where pulp molding products are directly hot-pressed without pre-drying), the hot-pressing time typically exceeds 1 minute to ensure complete drying of the products and prevent mold or deformation caused by residual internal moisture. The specific duration can be flexibly adjusted based on the thickness and material density of the pulp molding products to meet the production needs of products of different specifications.
The pulp molding hot press we provide adopts a thermal oil heating method (ensuring uniform temperature rise and precise temperature control, suitable for continuous pulp molding production) and has a pressure specification of 40 tons. It can meet the shaping needs of small and medium-sized pulp molding enterprises for products such as food containers, egg trays, and electronic liners, making it a key supporting equipment in the pulp molding production line.
