Proceeding step by step. No matter how complex the shape of the product is, its wall thickness is consistent everywhere. After the pulp molded product is formed, it will be a wet paper base with a moisture content of
because the power that pushes the slurry to the mesh mold for filtration is a vacuum, and the maximum force does not exceed one atmospheric pressure. At the beginning, the wet paper blank formed by Dongguan Qianyi Environmental Protection Technology Co., Ltd. is adsorbed on the mesh mold. The wet strength is very low and must be closed by another corresponding convex or concave mold to place the wet paper blank in the mold cavity after the mold is closed. Internal air pressure is used to transfer the pulp molded products. The pulp molded products are formed on a single convex or concave mold and transferred in the mold cavity after the mold is closed. Due to these particularities of pulp molding, product design and mold design are more difficult. 3. Pulp molded product design Dongguan Qianyi Environmental Protection Technology Co., Ltd. Pulp molded product design is not just the design of structural equipment. Many of the properties of the product are determined by raw materials, additives, fillers and production processes. Therefore, the design of pulp molded products is a comprehensive technology of process and structure.

In addition to the general physical strength and other requirements for paper Dongguan Qianyi Environmental Protection Technology Co., Ltd. products, some basic requirements should also focus on the following properties from the process and structural design according to the different uses of the products to meet Specific usage requirements.

Absorptivity: The liquid-repellent properties of pulp molded products include the ability to absorb water, oil, ink and other liquids, which is particularly important for paper tableware.
