Pulp molding is also known as plant fiber molding, it is a processing method of plant fiber pulp through special molds into various molding products. There are mainly dry pressure methods and wet pressure methods.
Dry pressure method pulp molding process, is a process of pulp with a certain concentration of slurry, add an appropriate amount of additives, through adsorption molding to form wet paper mold, wet paper mold billet from the mold into the drying road (mold drying), and then hot pressure shaping after the drying products.
Wet pressure pulp molding process, is a certain concentration of pulp, add an appropriate amount of additives, through the adsorption to form wet paper mold, wet paper mold is transferred to the hot pressure molding mold for drying (mold drying), to produce molded pulp products.
Pulp Molding Process Description
Pulping
Based on raw pulpboard, waste paper, cartons and other fibrous materials, the paper is converted into fibers and suspended in water through a series of processes such as breaking and refining, forming a pulp slurry. Depending on the characteristics required for the final product, the fiber length and pulp concentration can be flexibly adjusted to meet production needs.
Forming
The pulp slurry is dewatered on the mold through vacuum suction to form a green body. The prepared pulp is transferred to the forming mold via the suction system, where it forms a wet molded blank. At this stage, the blank has no hardness and contains a large amount of moisture, but the basic shape of the product has already been formed.
Drying
After pulping and forming, molded pulp products usually contain a relatively high moisture content. To ensure their performance and quality, they must be processed through a drying operation. The formed molded pulp products are then dried in hot air at 180–220 °C. Driven by fans, the moisture evaporated from the products is extracted from the drying chamber.
Hot Pressing
After the forming and drying stages, the pulp products are basically set in shape. They are then subjected to hot pressing under high temperature and relatively high pressure so that their appearance becomes neat and smooth, while their toughness and shock resistance are improved. The process typically operates at temperatures of 180–250 °C.
Demolding
The wet molded blank formed on the forming mold undergoes hot setting, during which about 98% of its moisture is evaporated by electric heating, giving the product good toughness and strength. Depending on requirements for product precision and surface smoothness, the demolding time is generally between 120 and 180 seconds.
Trimming
After hot setting, the molded products still have burrs around the edges. Through the trimming process, the finished products become more refined. Trimming is generally divided into straight cutting and ring cutting. Different trimming methods can be selected according to product requirements.
Bonding and Assembly
Bonding can also be regarded as a laminating or compositing process. To enhance strength, products are often made by bonding two molded pulp parts together. In addition to providing better rigidity, the overall packaging appearance is also more refined compared with single-piece packaging.
Materials Used in the Pulp Molding Process
Waste paper is one of the most common natural fibers used in pulp molding process. It is readily available, affordable, and can be easily recycled. Waste paper is used to create a range of packaging products, such as trays, bowls, plates, and cups.
Sugarcane bagasse is a byproduct of sugarcane processing and is a popular natural fiber used in pulp molding process. It is biodegradable and compostable and can be used to create a range of packaging products. Sugarcane bagasse is also lightweight and strong, making it an ideal material for packaging.
Bamboo is a fast-growing and renewable natural fiber that is used in pulp molding process. It is durable, lightweight, and biodegradable, making it an eco-friendly alternative to traditional packaging materials. Bamboo can be used to create a range of packaging products, such as trays, bowls, plates, and cups.
Wheat straw is a byproduct of wheat production and is used as a natural fiber in pulp molding process. It is biodegradable and compostable and can be easily molded into a variety of packaging products. Wheat straw is also lightweight and strong, making it an ideal material for packaging.
Wood pulp is a natural fiber that is made from wood chips and is used in pulp molding process. It is biodegradable and compostable and can be easily molded into a range of packaging products. Wood pulp is also lightweight and strong, making it an ideal material for packaging.
