1. Egg Tray Molds—Key Part of An Paper Egg Tray Machine

Importance of Molding Dies

For one thing,  a wide range of molded products can be manufactured by different molding dies. For the other thing, they also have a lot of influence on the quality and quantity of molded pulp products. While designing molds, many factors should be taken into account, such as the shape, appearance, size of groove, even the space between each groove. Considering that the molding dies are used frequently, their texture should be durable in use. We have an innovative design team to meet all your requirements.

Various Paper Pulp Molding Equipment from Beston

As the key part of the whole molding system, pulp forming equipment represents the technical merits of a company. As a rule, there are two kinds of molds, namely, forming mold and transfer mold. Beston Group offers many types of rotary molding machines for different customers. The output ranges from 800 to 6500 pieces per hour. We are providing the most satisfactory solutions that help our customers build a complete egg tray production line. In order to extend the scope of products without increasing the investment costs, we create detachable molding dies. In this way, it is possible for our customers to produce egg trays, fruit trays, shoe trays, etc. with one molding machine.

 2. Vacuum Pump

It is mainly used in forming process to attach the pulp fiber to the mold and remove the most water of pulp. As a necessary part of egg tray making machine, it has the following functions.

Improving adsorption capacity.

On the one hand, it can improve the compactness between the molds and pulp as well as the density of pulp fiber. As we know, both dehydration and forming processes are in connection with the adsorption capacity. That is to say, the vacuum degree has a great impact on the quality of pulp products, such as appearance, durability, stiffness. In our molding system, a safe and stable vacuum pump is used, which features low noise and high vacuum.

Removing some water out. 

On the other hand, most water is pumped out to increase the efficiency of drying system. From this perspective, it is also a dehydration process. The water tank is mainly applied to store vacuum and water to keep vacuum stable during the production process. Better yet, the water can be effectively recycled. The vacuum pump designed and developed by Beston has the advantages of high vacuum stability, small occupation area, and easy maintenance. Our vacuum pump has been praised by the molded pulp products manufacturers at home and abroad and it is widely used in a paper pulp tray production line.

3. Air Compressor

This is a machine compressing air to increase gas pressure, which is widely adopted in many industries. It is also a vital unit of egg tray production line. In the molding system, we use piston air compressor to separate the molded products from the dies.

4.Cleaning Device

Cleaning system is an optional part of the molding system, which is easy and energy-efficient to assemble. It is used for flushing the residual pulp off after demolding. For one thing, it is beneficial to mold maintenance to extend the service life of paper tray forming machine. For another, it ensures the quality of pulp products. As for different pulp molding machines, we have different cleaning devices, such as high-pressure cleaning pump, cleaning sink.

Role of  Egg Tray Molding System

This system plays a key role in an egg tray production line. The design and quantity of molds directly affect the quality and yield. Besides, the factory scale is determined by this system to some extent. For these reasons, molding is considered as the most important link in an egg tray production process. In a general way, this system is composed of a vacuum pump, an air compressor, a pulp molding machine and cleaning devices. Each piece of equipment makes a great difference, so it is crucial to choose suitable pulp molding equipment. With an experienced technical team, a complete egg tray production line and superior components can be provided by Beston Group.

How Does Egg Tray Molding System Work?

In general, molding system follows pulping system. It aims to make the paper pulp into molding products. Here are the specific procedures. First, pump the pulp into the forming molds. Then shape up through absorbing and pressing. So it often needs the help of vacuum pumps and air compressor. Then the wet products are moved out of the molds by transfer molds. After demolding, the cleaning device performs its role to flush the molds. Here is the paramount part of a pulp molding production line. Although it sounds complex, Beston egg tray molding system is often fully-automatic and easy to operate. Thus, it is significant to choose durable and reliable pulp forming machine to reduce the labor input and improve efficiency. Our company is positioned to be the best equipment supplier for all egg tray manufacturers.

We always strive to be a model for egg tray machine suppliers to offer you the best products and the best service at the best costs.
