Pulp molding is a process that turns waste paper and cardboard into useful packing materials like egg trays, fruit trays, egg boxes (cartons), coffee cup trays, and more. One of the most common types of pulp moulding machine for sale is the egg tray machine. With such a machine, waste paper can be recycled into sturdy packaging for chicken eggs, and that packaging itself can also be recycled. Furthermore, such a machine produces no pollution, and the raw materials are just water and paper, so it is environmentally friendly. By switching up the molds, other paper pulp-based items can also be created.
Stages Of Pulp Molding Process
There are four main stages in an egg tray production line: pulping, forming, drying, and packing. During the first stage, pulping, water and paper waste are mixed together using a hydraulic pulper. To ensure the right consistency of pulp is produced for the creation of high-quality end products, the correct ratio of water to paper must be used. This ratio will differ depending on the sturdiness requirements of the end products.
Once the pulp has been created it is moved to a pulp pool. From there, a vacuum pump is used to move it onto the pulp forming machine. Once the pulp is formed, it is transferred onto mold transfers. The size and design of the mold transfers will determine what type of egg trays are produced and the scale of the production line.
The duration of the drying process will depend on the system used and the surrounding environment. Cheaper plants just rely on natural drying, which is highly dependent on the climate. Other plants use brick drying systems or metal line drying systems. Once the egg trays are dry, they are sent to the packing area where machinery is used to pack many units together for more efficient transportation to distribution centers.

The most advanced pulp molding machines are completely automatic. With such a machine, factory productively is improved tenfold, and the cost of labor is radically lower. Automatic machines only require around six workers to operate at full efficiency, and they can produce upwards of 6000 trays per hour. It’s important to look at the output rate when comparing different models. Keep in mind that automatic machines require a much greater initial investment, so many mass production packaging plants opt for the more affordable semi-automatic egg tray machine.
Customizations
Pulp molding machines from the best manufacturers can be customized to meet the specifications of the buyer. Therefore, it’s a good idea to know exactly what your company’s specifications are before you start obtaining quotes for different machines from different brands.
Price Discounts
Egg tray machines costs vary greatly depending on many factors including the size of the egg crate making machine, the operation mechanism of the machine (manual, semi-automatic or fully-automatic), the machine’s warranty, and the location of the supplier. If you are looking for the best prices, be sure to check out international vendors like those based in Indonesia, India, South Africa, and China. More information here
