Though there is an increase in the usage of plastic worldwide in the last few years, many countries are restricting the use of plastic since it is not biodegradable. Hence, many businesses are forced to consider using biodegradable materials like paper for packaging the products they are selling. This has increased the demand for packaging made from paper and pulp. Many businesses are considering purchasing a machine for making pulp molded products, and are interested in finding suitable pulp molding machine manufacturers who can supply the machine which they require at an affordable price.

Before finalizing the manufacturer for the machine for making paper pulp molded products, a prospective buyer should understand the applications of the machine, and the process for making the products from waste paper. Though egg trays are the most widely used products which are made from waste paper pulp, there are other products like apple trays, egg cartons, fruit trays, seedling tray, shoe support, electronics tray, trays for bottles which can be made from the pulp. While some machines can make only one kind of tray, other machines allow the user to make different types of molded products from pulp according to the user requirement, so the manufacturer should be selected accordingly.

Though waste paper is the most commonly used raw material for the pulp molding machine, such as egg tray molding machine, the machine manufacturer can design it to process different types of related material like cardboard, agro waste. The raw material is converted into paper pulp using a hydraulic pulper, which converts the paper pieces into a slurry with paper pulp by adding water. The pulp produced is then passed through a pulp refiner, which ensures that the pulp produced is of size small enough to be converted into mold required. If the pulp pieces are large, it may be difficult to form a mold of the uniform quality required.

The most important part of the machine is the process of molding the pulp in the shape desired, using the molds which are provided. The pulp molding machine is applying pressure to the paper pulp using the mold, so that it is formed in the shape which is desired. In some cases the molded pulp product will have two or more parts, so a forming mold and transfer mold may be required. The paper pulp at this stage will have a high moisture content, so the molded pulp should be dried, to remove the unwanted water. If the molded product contains a lot of water, it could result in mold at a later date, adversely affecting the quality.

After the molded product from pulp is dried to ensure that the moisture level is below the desired level, it is then packed, so that it can be supplied to the customer using the packing section of the machine. Manufacturers are offering different options for the machines, they can supply each section separately or all the sections together. Depending on the amount the user is willing to invest, the buyer of the machine for molding paper pulp can opt for a semi-automatic machine, manual or fully automatic machine from the manufacturers. Manual machines are cheaper, yet the labor expenses are usually higher.

Before purchasing the machine, the buyer should estimate the number of paper molded products that he will be able to sell based on demand and market conditions. Most of the manufacturers are supplying machines of different capacities based on the demand from their customers. Larger machines will be more expensive, require more electricity, will require more space for installation, and will also need more labor for production. Hence most of the buyers of these machines are placing orders with egg tray machine manufacturers only when they have confirmed orders. They are also ensuring that they have adequate raw material like waste paper.

Based on the requirement of the customer, the manufacturers can ensure that the molded pulp tray or other product is supplied in different colors. The products can be made waterproof by using some additives. The machines are usually made from powder coated steel to ensure durability. The manufacturers design the automatic and semi automatic machines to have a control panel so that the user can set the parameters and control the machine. The machine manufacturer has a provision for changing the molds quickly so that one machine can be used for making a large number of different products from paper pulp. This allows the machine owner greater flexibility, increasing profit.
